What your child will learn
Four big ideas, discovered by testing rather than by being told.
- What gravity is — and how it moves your car
- The difference between stored energy and motion energy
- How ramp angle, weight and wheel size change how far a car rolls
- How to collect data and use it to make real design choices
What's in the box
Everything your child needs, except a few books from home.
- Building bricks and wheels
- 2 weighted blocks
- The ramp board
- A measuring tape
- Your workbook
- The companion guide, for the grown-up helping
You'll also need three to five big books from home. They set the ramp's height.
What you'll do, section by section
Seven short videos, one for each part of the workbook. Watch a step, then do it yourself.
| Section | What you'll do | What you'll learn | Video |
|---|---|---|---|
| Start Here | What you'll doOpen the box and meet the parts. | What you'll learnWhat's in the kit, and how to test safely. |  1:54 |
| Activity 1 · Build & Roll | What you'll doBuild the car. Then test it on ramps of different heights. | What you'll learnHow the ramp's steepness changes how far the car rolls. |  11:01 |
| Activity 2 · Load It Up | What you'll doAdd weights to the same car and run it again. | What you'll learnHow the weight of the car changes how far it rolls. |  3:50 |
| Ramps Long Ago | What you'll doLook at ramps people built long ago, and ramps we use today. | What you'll learnThe ramp is one of the oldest tools people have. |  1:45 |
| Activity 3 · Size It Up | What you'll doSwap the wheels. Test the same car again. | What you'll learnWhether wheel size changes how far the car rolls. |  3:33 |
| Science Spotlight | What you'll doFind out why the car moves at all. | What you'll learnGravity pulls it. Stored energy becomes motion. Friction slows it down. |  2:04 |
| Grand Challenge | What you'll doDesign and race one best car. | What you'll learnHow to use three tests' worth of data to make a real choice. |  1:54 |

The workbook leads the way
Your child builds, tests, and writes down what they find. The videos follow the workbook page by page — you don't need to know any science to help.
