We built an elastic band powered Lego car

Math

• The child learned about measuring distances as they adjusted the length of the elastic band to determine the car's speed.
• They practiced counting and quantifying as they counted the number of rotations the wheels made with each trial.
• The child applied basic addition skills by calculating the total distance traveled by the car after multiple trials.
• They explored geometry concepts such as angles and shapes by observing how the car's path changed based on the angle of the elastic band.

Science

• The child learned about potential and kinetic energy by understanding how the elastic band stores energy and transfers it to the car's motion.
• They explored the concept of friction by observing how different surfaces affected the car's speed and distance traveled.
• The child gained an understanding of force and motion by experimenting with different elastic band tensions and observing the resulting movements of the car.
• They engaged in the scientific method by formulating hypotheses, conducting experiments, and analyzing the results.

For continued development related to this activity, encourage the child to explore other simple machines and their applications in real-life situations. They can investigate pulleys, levers, inclined planes, and gears. This will further enhance their understanding of physics and mechanical principles.
