Lillian, 4th grade Digital Learner @ Buck Lake
My name is Lillian and I am in 4th grade. I am the only member of this team, but my mom and dad (who are 39) helped a lot with the problem solving side of things.
My solar car: The Dragon’s Lair!

Here are the the links to my team explanation & vehicle performance.

Flow of Energy
The energy that powers my solar car starts at the sun. The light energy flows from the sun to the solar panel, which converts it into electricity, and through the wires to the motor. The motor uses the electricity to spin the 1st pulley wheel, causing the rubber band to move and spin the 2nd pulley wheel. The 2nd pulley wheel is attached to the axle, making the axle spin also. Since the wheels are attached to the axle, they rotate, moving the entire car forward.
Balsa wood, 3-volt solar panel, motor, bamboo kabob sticks, hot glue, wax, T-Rex tape, scotch tape, metal, paper, feather boa, origami paper, wires and alligator clips, pulleys, medium wheels, and craft sticks.
Problem 1: My car wasn’t moving! My mom and I figured out that my motor was spinning inside my gear, and my gear wasn’t moving. (The hole on the gear was too large. It wasn’t staying in one position on the motor.)
Solution 1: Switch to pulleys! If one thing doesn’t work, try another. I switched to pulleys and it’s working really well.
Problem 2: My solar panel had to be removable! My teacher needed all the solar panels back after we finished our projects. So, since I couldn’t use permanent glue, I used wax. But well… wax melts in sunlight.
Solution 2: After I looked at some other team’s ideas for attaching their solar panels, I decided to attach the solar panel to the bamboo skewers with hot glue, which would come off easily.
