Vehicle Experiments

We took our robotic car back out of its box and this time, tried programming with it.

We connected the motor to a computer chip, and put that all together on the car. With this, we were able to use code to tell the car what to do. Similar to when you push the gas pedal on a car, we could tell the car to move forward and backwards.

Using our code and our brains, we tried to make the car go to the red cones and stop just before. We adjusted and did our best to change the speed and period of driving.

It was an interesting experiment. Some of us wanted to make the car turn, but with only one motor, we couldn’t. Next time, we will add another motor!





Look at things that float in the water!

Our week of vehicle experiments has continued, this time by looking at things that float in the water.

When we talked all about safety and parachutes, we also talked about safety on ships. What happens if someone falls overboard? Well, we can throw them a life preserver. It can float! What about if you are riding on a motorboat? You should wear a life jacket! It can float too. How about at the beach? Look out for the life guard! Hm… Did you notice the pattern?

Speaking of the life preserver, how does it float? And why can people float sometimes, but not always? We talked all about sinking and floating, including with a model. We tried all different kinds of things, and came to some conclusions.


安全性とパラシュートについて話したとき、船の安全性についても話しました。もし誰かが海に落ちたら?救命胴衣を投げてあげましょう。浮くこともできる!モーターボートに乗っている場合は?救命胴衣を着るべきです!これも浮きます。ビーチではどうでしょうか?ライフガードに気をつけて ふむ… この模型に気づきましたか?


First, we need to think about the material. Stone will sink immediately. Wood and plastic will usually float. That’s a good start.

Then, we need to think about balance. If our floating thing isn’t balanced, it won’t make a good boat, and might take in water. Air escaping from under the Lego block made it sink right away. Our PET bottle boat sunk after one side was too heavy.

Finally, we can think about air. Air is lighter than water, so if we fill something with air, it makes a good flotation device! Even a bottle 99% filled with water might float to the top just from that little bit of air.

We spent a whole morning trying different things and building miniature boats for our Lego person. I’m sure they could have used a life guard by the end of it!





Make our own boat!

We took that knowledge and decided to make our own boat. Last year, we used sticks to make a raft. It looked like it would work well, but the glue did not hold it together strongly.

This year, we will try egg cartons. They are already together, so we don’t need to use glue. We added some color with crayons instead of paint, hoping that the wax would help to repel water. Our material is only cardboard though, so don’t leave it in the water too long!

After the coloring, poking holes for the mast, designing and attaching the sail, and any finishing touches, we were finally the captain of our own ship!

Better take care, because our class is full of expert sailors and gruff pirates😄 Hoist the sail and pull up the anchor!

Bon voyage, fair winds, and following seas!

私たちのクラスは熟練した船乗りと不機嫌な海賊でいっぱいなので、気をつけたほうがいいですよ! 帆を張り、錨を上げろ!




そこで、今回「小学生の間に英検準2級をめざすCHES Saturday Class」を開講し、単なる「英検対策」ではなく、基礎的な英語のルールを「学ぶ姿勢」、とっさに反応できる「英会話力」、自分自身の思いを「声に出せる思考力」も育み、お子さんの将来に活かせる英語学習を身につけることをめざすことにしました。

目標達成にはまず基礎的なルールを確実に学び、同時に練習する必要があります。そして、もしも目標を1つ達成することができれば、その「How to do」と「 What to do」が身につき、応用していくことで他の課題の目標達成にも役に立ち続け、お子さんの将来に活かせるはずです。
