Grade 2 Science · World 6: Push & Pull Playground · Level 43
Test Your Design
Record trials in a table and decide if a design works as intended.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 43
- After you build a design, test it. Do it more than once, to be sure it works every time and not just by luck.
- Keep everything the same except the one thing you're testing: the same car, the same push, the same floor.
- Write the results in a data table. This class tested two ramp designs three times each.
- Design B rolled farther in every trial, so it worked better at making the car go far. If a design doesn't work every time, improve it and test again!
Georgia Standards of Excellence in Science:
- S2P2.c — Record and analyze data to decide if a design solution works as intended to change the speed or direction of an object with a force (a push or a pull).
