This fourth grade Virginia SOL (4.1, 4.2) aligned experiment has students exploring how friction effects cars traveling down different surfaces.
In my directions, I have given suggested surfaces to use, which have worked great for me, but the surface section of the data table is left blank if you wish to change the surfaces to fit your classroom needs.
Materials needed for this experiment:
-Ramp or cardboard to create incline
-Books to put underneath incline ramp
-Variety of surfaces to use for independent variable
-Rulers & meter sticks
Components of this experiment:
1. Students will complete the questions scientific method. This includes hypothesis (student formed), independent variable, dependent variable, and constants in the experiment.
Independent Variable: Surfaces (materials)- We change!
Dependent Variable: Distance car travels off ramp
Constant: Toy car, number of books holding the ramp up, etc.
2. Students will complete the experiment using the toy car. Each material or surface should be tested 3 times to make up for human error. Students will record the distance the car traveled off the ramp inside the data table on the first page.
3. Once all surfaces have been tested and the data is recorded, students will complete the 'after experiment' questions.
4. Students will use their data they collected from their experiment and create a line graph for each surface they tested. They should graph all three trials.
My students LOVED this experiment! If you have any questions, please let me know. If you enjoyed this product, please leave a rating or comment below! Thank you!
