Edible Cars in Science Class!!

 WCMS students had fun creating edible cars this month.

Here's what Sarah Hall, one of Mrs. Knipp's 7th grade students, had to say about the project:

    Here is some of what we learned during this unit and with our edible car project:

 First of all we learned that friction is a force that holds back the movement of a sliding object. We realized that in our car we did not want friction, because our car wouldn't roll down the ramp as well. Therefore, we used slick wheels (Salami, in the back), and placed some marshmallow pieces in between the wheel and the banana we used for the body. Also, we learned that acceleration is the rate at which an object changes its velocity or vector quanity. To increase acceleration with our car, we used smaller wheels in the front and larger wheels in the back. Next, we were taught that momentum was mass, or weight, multiplied by velocity which is the rate at which an object changes in position. To increase our momentum, we used a banana for its higher weight and once again, the smaller wheels in front and larger wheels in the back increased our velocity as well which helped our momentum. Then, we learned that inertia was the tendency to resist changes in their state of matter so we froze our banana car to keep in solid and to prevent our marshmallow fluff from melting. Lastly, we expanded our knowledge by learning that aerodynamics is the study of forces and the resulting motion of objects through the air, so we used the banana because of its pointed front and stem in the back.

Check out all of the creativity!
