Today during
our normal science block we started a new project, which was a lab, called "How Long Does It Take a Bean Bag to Drop?" The purpose of this lab was to see how the distance an object is dropped affects the time it takes the object to fall.
our normal science block we started a new project, which was a lab, called "How Long Does It Take a Bean Bag to Drop?" The purpose of this lab was to see how the distance an object is dropped affects the time it takes the object to fall.We dropped bean bags from different heights:
- the seat of a chair in the science lab
- the lab table
- top of the doorway
- two different heights of stairs.
We dropped the bag three times from each height. That was the fun part!
After we had finished dropping the bags and finding out the time, we had to graph the data we got and the find the average speed. To find the speed you divide the distance by the time. By this time class had already ended, so we finished the rest in the next class. I think that everyone agrees that this was one of the more interesting labs we have done so far. This class was a long class, but there isn't much to say because we only worked on our lab.
Useful definitions for distance, average speed and speed:
Distance: The extent of space between two objects or places.
Average Speed: The overall rate of speed at which an object moves; calculated by dividing the total distance an object travels by the total time.
Speed: The distance an object travels per unit of time.
