Starting with the ideas of friction, we thought of many examples of why things slow down. We took our investigation to the hallway to test out different surfaces. Which surface caused our toy cars to slow down? What surfaces were harder for the car to travel on? We later took to the skies! We all agreed that wind is a force. But can that force cause friction? We swung parachutes, walked into the wind, and pulled plastic bags. 
The next idea we talked about was gravity. How do things fall? We talked a bit about the "why" as well, but watching things fall was definitely a lot more fun. Using a ball of yarn, string, tissue, paper, and a paper helicopter we got to witness the path they took on the way to the ground.
We then took ramps to apply what we knew about friction and gravity. What ramp height made the car move and go the fastest? We came to the conclusion that the answer was "high."
Below is our schema showing what we have learned so far.
1. Friction happens when things rub together.
2. Friction slows down moving things.
3. Friction can make things hot.
4. Gravity is a force that makes things fall toward earth.
5. Things stay still until a force happens.
Here's a side note: Super cool videos related to gravity? Try "how to wash your hands in space" or "no gravity music video" (safe for kindergarten)
