Experimenting with Air Drag and Streamlined Vehicles
We used just a few materials for this experiment (I’m including the affiliate links for your convenience.)
Two identical toy cars. We used ones similar to these.
colored cardstock, cut into rectangles
stack of books
Prediction: Ask your child their predictions! What will the shapes do to the cars? Will one shape go faster? Why? What will happen when air is applied to the cars?
What is drag? Drag is air resistance caused by disturbances in the flow of air over an object. This force slows down moving objects like the cars in our experiment.
Have fun with your air flow experiments! You might also like our Bernoulli’s Principle air glider project:
