6th Grade's 1st Challenge

2010-10-14T10:02:00.000-07:00

The 6th grade began their year in science with a challenge: Construct the tallest stable tower you can using only uncooked spaghetti and marshmallows. Many of this year's projects will involve designing, creating, and testing products; the Spaghetti & Marshmallow Tower was an introduction to product design and distribution of forces, as well as cooperative group work.

Building a safe and supportive community is a major focus in our middle school at the beginning of the year-- students will all experience the most growth in middle school if we have a strong community in which to learn and take chances. We have been dedicating our time to learning about what makes each of us unique and what brings us together as a community. These studies will culminate with our "Museum of Us" evening. All family members and friends are invited to see the middle school students' exhibits at the school on Thursday, Sept. 23, 7:00-8:00 pm.
After we finish the Family Tree piece of the "Museum of Us," we'll be moving on to study physics in science class. The first questions we'll be asking are: What is a force? What happens when forces are balanced? What about when they are unbalanced? In science class we'll become aware of forces all around us, how they interact and how they affect us in our everyday lives. Then we'll move on to describing and measuring motion.
On another note, as the school year begins, it's important to focus on building strong study habits. I recently came across the following article describing some of the latest research on effective study habits: http://www.nytimes.com/2010/09/07/health/views/07mind.html?src=me&ref=general

8th Grade Motion Experiments

2010-04-28T19:20:00.000-07:00

Just before April break, the 8th grade presented their findings after conducting their own experiments involving MOTION. Many groups used toy cars; a few groups used ramps.
Here are a few questions tackled by our investigative teams:
How does the mass of an object affect the distance it will travel?
How does the surface material of a ramp affect a car's speed?
How does the steepness of a ramp affect how fast a car moves across the floor?

The nervous system in our body is the way we react to things like pain, laughing, etc. One nerve can be up to 2 feet long! But, it could also be microscopic. Our spinal cord is just a big bundle of neurons (nerves). If our spinal cord is broken it could cause major problems to our nervous system. There are millions of neurons in our body. The neurons have many parts like the nucleus, axon, myelin sheath, and dendrites.
Here are some suggestions for people who don't exercise. Exercise has a massive effect on your body especially the brain. Exercise helps the brain calm down. Exercise also helps organize your thoughts. And believe it our not it improves your memory. Exercise can increase a person's ability to plan and organize thoughts. The more exercise you get, the farther you will be able to run and you will become less tired. So those are some reasons you should exercise more.

Physical Activity Boosts Brain Activity

2010-01-25T18:10:00.001-08:00

Recent research shows that physical activity improves certain aspects of brain function. Very soon, all middle school students will be studying the science behind this important link. I'm proud that Guilford's middle school population is so active, fit, and (for the most part) happy to be outdoors! We'll be incorporating more physical activities into our daily school schedule so that we can reap the academic benefits.
Please read the article in the post below-- it includes tips for helping students achieve academic success (yes, exercise is one suggestion!).

Six Ways to Help Students Raise Their Grades

Friday, 06 June 2008 10:48 administrator

By Annie Burnquist
With the school year ending, millions of high-school students are preparing for that last minute push to raise their grades -- and parents are looking for ways to help. Here are six tips to boost your child's final-exam scores.

1) Exercise the body to give the brain a boost.

Physical activity increases blood flow to the brain, feeding it with oxygen and learning-boosting nutrients like glucose. "Exercise in many ways optimizes your brain to learn," says Dr. John Ratey, a Harvard Medical School professor.

Getting students to workout greatly improves their classroom performance. One study found that 15 to 45 minutes of exercise before class reduced fidgeting among children by half. In a study that looked at three groups of students with different physical education routines, the group that exercised the most did the best on tests, even though they spent the least amount of time in class.

2) Create a healthy study space.
Where kids study is almost as important as what they study. So designate a specific spot for studying. Doing so sends the message that your household takes academics seriously. And although the area should be free of distractions like TV, video games, and phones, it should also reflect what the student needs -- not what mom wants. Developing this habit early in life will pay off immensely during college.

Aesthetics matter. One study found that grades were 25 percent better for students who study near a window; natural lighting promotes concentration.

3) Encourage interactive learning.
An ancient Chinese proverb goes: "Tell me, I forget. Show me, I remember. Involve me, I understand." Students perform better when actively engaged with the material. A great way to ensure that engagement is to hire a personal tutor.

Tutors were once too expensive for most Americans. Calculus tutors cost about $100 per hour -- and an instructor's quality varied with location. That's all changed thanks to online tutoring services They provide all the benefits of old-fashioned tutoring -- like one-on-one attention, a customized educational experience, and instant feedback -- at a considerably lower price. Kids who use our tutoring service typically raise their grade by at least half a letter.

4) Get plenty of sleep.
Sleep is essential to the brain's ability to learn. Teenagers should get at least eight hours each night. Grade schoolers need at least 10. Late-night cram sessions don't produce much long-lasting knowledge, and they compromise the ability to analyze and recall information during tests.

One study by Harvard psychiatry professor Robert Stickgold found that after learning a new skill, student performance didn't improve until after at least six hours of sleep. "It's as if you have to wait for the dough to rise," he explained.

Psychology professor Pamela Thacher cross-referenced college student grade point averages with sleeping habits and found that "you can't do your best work when you're sleep-deprived. . . If you use all-nighters, your GPA is slightly lower on average."

5) Encourage communal learning.
Group learning is more exciting than thumbing through a textbook. As social psychologists David Brandon and Andrea Hollingshead have concluded, "interaction with others leads to active processing of information by the individual."

Thanks to the internet, kids don't need to confine their study partners to people in their immediate area. There are plenty of high-quality online forums for kids to talk to each other or adult experts. As psychology professor Rena Palloff and international studies professor Keith Pratt noted in a paper on online learning communities, the "keys to the learning process are. . . the collaboration in learning that results from these interactions."

6) Have a study plan.
Creating a study plan is an effective way to manage stress and use time efficiently. A recent study by the American College Health Association rated stress as the #1 impediment to academic performance among college students in the

United States

. And during finals season, academic anxiety can be especially bad.

Luckily stress can be substantially reduced with just a little bit of planning. By creating a realistic study schedule and breaking down assignments into small, manageable pieces, students can avoid stress leading up to an exam.

Is this an animal cell or a plant cell? How can you tell?

December Curriculum Update

2009-12-13T09:48:00.000-08:00

After Thanksgiving, 6th, 7th, and 8th grades started new units in science class. 6th and 7th have been learning about the tiny units that make up all living things: cells! After we got some perspective about the sizes of things (atoms, molecules, cells, tissues, organs...), we learned about the many parts of cells (organelles). We'll spend next week making our own Cell Cities!
Each student will make a city that carries out all of the jobs that our cell organelles perform.

8th grade is working on an electricity unit. We've seen the effects of static electricity, and now we're moving on to current electricity. Students are working in pairs to complete their electricity challenges. So far, they've succeeded in lighting a bulb with only a wire and a battery (not as easy as it sounds!); next week each team will explore circuits and invent a device that can tell if a material is a conductor or nonconductor.

After the holiday break, we'll be learning about how materials move in and out of cells. Experiments will involve eggs, potatoes, vinegar, salt water, food coloring, and corn syrup. No, we won't be eating them! We'll also focus on the important processes that happen in our cells (cellular respiration) and in plant cells (photosynthesis).

The Microbe Investigators did an excellent job!

2009-11-22T12:08:00.001-08:00

The science room was bustling on Friday as the Microbe Investigators presented their experiments to the public! The 7th and 8th grades hosted two 1st grade classes, the 6th grade, and many parents. The Investigators taught our visitors about microbes and graciously answered questions. One investigative team even brought microbe-produced food to attract visitors to their poster (it worked!).

REMINDER!

2009-11-17T18:31:00.000-08:00

I just want to remind everyone that on Thursday mornings, I lead a Science Extra Help session before school. Students are welcome from 8:00-8:30 (in the science room). More students tend to come just before a test or project due date, but middle schoolers can join me any Thursday as long as they tell me the day before that they'll be coming.

6th Grade Recycling Ambassadors

2009-11-07T11:15:00.000-08:00

For the past three weeks, the Recycling Ambassadors have been learning about where our waste goes. We visited the Windham Solid Waste Management Recycling Facility to follow the journey of items in our recycling bins. In fact, while we were on a tour of the facility, a truckload of recyclables from Guilford was dumped right in front of us! We got to see what happens in the busy facility and find out where our glass, plastic, paper, and cardboard ends up. And, in case you were wondering, the 6th grade class, Mrs. Davis, and 2 chaperones weigh 2,581 pounds! (We all got on the scale together.)
We've talked about reasons that people recycle as well as what can and cannot be recycled in Guilford. In teams of 3-4, students created, rehearsed, and presented lessons to grades K-5 in our school. Different teams made Powerpoint presentations, posters, skits, and interactive games to play with the younger students. It was very exciting to have teams come back to our science room feeling so excited and proud of how well their presentations went. In fact, teachers have been asking me if we can come back to work with them throughout the year. The Recycling Ambassadors have been working hard. As this unit draws to a close, we'll be moving on to do more hands-on scientific investigations.

Microbe Investigations

2009-11-07T10:24:00.000-08:00

The 7th and 8th grades have been studying microorganisms (bacteria, viruses, yeast, mold...). At this point in our unit, all students are undertaking investigations that they designed. The Microbe Investigators came up with their own experimental questions and made a plan to answer them. These are some of the questions currently being investigated:

Where are there more microbes-- inside or outside?
Does temperature affect the growth of microbes?
Which has more microbes- blue cheese, garlic cheddar, or milk?
Does the boys' or girls' bathroom have more bacteria?
Does using hand sanitizer or washing with soap and water eliminate more microbes?

Want to know the answers to these questions, and more? We'll be sharing our results at the Microbe Exhibit on November 20th.

The 8th grade has experienced mini-lessons with three guest teachers: Mr. Wood, Mr. Patno, and Mr. Mizrahi. Other 8th graders have been asking for this opportunity, and in the future we'll be learning from Miss Crowder and Mr. McPhail...and possibly others!

Junior Iron Chef Competition

2009-11-07T09:24:00.000-08:00

6th Grade's Farm to School Program had very exciting Wednesday last week!

The Challenge: Be the cooking team to make the most delicious apple crisp using local apples
The Prize: Our panel of judges will select the most scrumptious apple crisp. The winning recipe will be made by 6th grade for the entire middle school to enjoy next week!
The Event: Imagine this scene in the science room...

Teams of 3 are eagerly waiting at their prep tables; bowls, peelers, cutting boards, secret ingredient lists in front of them. The team names alone are enough to make your mouth water--Apple Crispies, The Crispy Cookers, Smashing Apples, Sweet Sugar Savers, The BFGs, and Crisp Crunchers.
Ms. Kramer and Mrs. Davis announce ground rules and the teams take off!
Teams send one member for ingredients and begin the frantic preparations: Flour is flying, apple peels are proliferating, salt is sprinkling! The Iron Chefs are working together and delegating tasks. Some chefs are carefully mixing their crumb topping; others are washing measuring cups before adding the next ingredient.
When the prep time comes to a close, all 6 crisps are lined up on a baking pan and baked to perfection.
Later in the day, the entries are revealed to the judges. The judges enjoy a spoonful of each crisp, cleansing their palates between tastings, and noting their comments on the judging sheet.
The votes are tallied...though all crisps are delicious delights, the winner is the crisp with the homemade caramel drizzled on top.
All Junior Iron Chefs get to eat the fruits of their labor :)

Tips for Parents

2009-11-07T08:37:00.000-08:00

The Middle School had our first round of parent/teacher conferences on Thursday and we'll be continuing on Monday. I found this article that I wanted to share with parents who are wondering how they can help their child be successful. It's from the National Middle School Association (www.nmsa.org).

Tips For Parents

The first tip is thinking ahead... One of our best tools as parents is being prepared. As your son or daughter gets to the middle school years, get ready for at least occasional conflicts. Think through what is truly important to you. Is the youngster's hairstyle as important as homework? Isn't curfew more of a concern than crabbiness? Obviously, dawdling is a lot easier to accept than drugs. As these give-and-take situations start, know ahead of time what areas you are willing to negotiate and what areas are absolutes.

Break down big chores into small parts. Sometimes young people feel overwhelmed by tasks, especially those they've let go for a long time. A disastrous bedroom, twenty-three overdue math assignments, a long-term project that's "suddenly" due in a few days (or hours!);all of these cause the preadolescent to choose to give up rather than get started.

Help your child by setting up smaller goals: clean off your bed; get five assignments done tonight; assemble the materials for the project. Preadolescents have trouble structuring tasks so that they are more approachable. In an even and off-hand way, we can help them in this.

Encourage your middle schooler to keep a daily list (weekly is too much) with a few things on it to be done that day. It may be necessary to assign a specific time to each task. When the task is completed, draw a line through it to show accomplishment.

Don't hesitate to remind your middle schooler about appointments and due dates. Try to think ahead about materials required for a project (unless you look forward to late-evening visits to K-Mart). This will not last forever. When this same child was learning to walk, we held his or her hands and made the path smooth. Now he or she is learning to take on a tremendous assortment of life-tasks and changes; hand-holding (but not the firm, physical grip previously necessary) is needed for about a year or so as your middle schooler gets started on the road to being a responsible adult.

Be willing to listen — but don't poke or pry. Kids this age value independence and often seem secretive. Keeping to themselves is part of the separateness they are trying to create. Let them know you'd love to help them, but don't push them into a defensive position.

If your child is in the midst of a longtime friendship that is falling apart, the best thing you can do is stand by and be a good listener. It is devastating for us to see our children hurting, but taking sides or intervening is not appropriate, nor will it help. Preadolescents do survive these hurts, especially if they know we are there to listen to their pain.

Friends are people who accept us as we are. They listen, they don't needlessly criticize, they back us up when we're right and pick us up when we're down. Be a friend to your middle schooler; some days kids feel you're the only one they have.

All friendships have ups and downs. Children need to learn that being "best friends" isn't always smooth sailing. People have differences of opinion and even get angry, but they still care for each other. This is what's going on when we get involved in those "I-hate-her-she-is-so-stuck-up-and-how-could-she-do-this-to-me" conversations. As parents we must help our kids see that one problem doesn't ruin a relationship, but stubbornness might. Middle schoolers have a lot of spats and falling outs, but often the friends are back together again in a short time.

When reprimanding, deal only with the precise problem, don't bring in other issues. "The trash is still here, and I want it out, now," is better than, "You are so lazy! I told you to take that trash out two hours ago and it's still here! You'd live in a pigsty, wouldn't you? Well, you aren't the only one in this house, you know..."

If the issue is minor, keep things light. The shoes on the floor, the wet towel on the bed, the carton left open; these are maddening, perhaps, but not earth-shattering. Call attention to them in a humorous way, so your middle-schooler knows you want action but you aren't being punitive. "Either the cat's smarter than I thought or you left the milk carton open on the counter. One of you please put it back before it spoils."

Don't use power unless it's urgent. Parents have the ultimate power, and kids know it. We don't have to "prove" it to them at every turn. Save your strength for those really important issues you've decided are non-negotiable. Eventually kids are going to possess power of their own, and we want them to be able to use it wisely.

Curriculum update, Sept 20

2009-09-20T18:38:00.000-07:00

We've had a busy start in middle school science! After we got to know our classroom community and procedures, we moved on to a pressing matter: how to identify poison ivy. We're going to spend time working on and learning on the Nature Trail this year and don't want While the 6th grade drew scientific illustrations of Toxicodendron radicans, the 7th and 8th grades came up with solutions to this itchy problem. Then the students presented their solutions (Pull it out! Avoid it! Spray it with herbicide!) and debated the pro's and con's of these proposals.
Last week (Sept. 14-18), we focused on the question, "What is Life?" and learned about the Six Characteristics of Living Things. Students in all classes generated questions about life on Earth, many of which we'll be revisiting as this year of LIFE SCIENCE progresses.
This week (Sept. 21-25), we'll begin to learn about the vast biodiversity that exists on Earth. We'll come up with our own ways of classifying items and learn about the classification systems that scientists have developed. Next week we have two guest speakers coming to our classroom-- Mary Lou Forward will share her own experiences with biodiversity in Madagascar, and Jesse Palmer will do trail work with us and discuss his upcoming trip to Antarctica. 7th and 8th graders met Jesse last year before he left for the South Pole, and he told me he's looking forward to seeing them again!
