Lesson 2

In this lesson, we will finish making a slide and compare the speed of the ball with which it will roll.

Step 6. Take two tubes and put them on the legs like rails. don’t forget about the distance between the rails for the ball you measured.

Step 7. Fix the rails with plasticine to the legs. Be careful, plasticine should not block the path of the ball.

Ready. 

Now let’s see for which group the ball will go faster along the hill.

Conclusion

In this project, the students made a roller coaster for balloons to understand the theme of speed. The students compared the speeds of the balls of different groups, thereby strengthening their understanding of the terms faster and slower.
