Student Created Labs
Recently, strange things have been happening in 4th
grade. The students have taken over and created their own science labs!! Classmates
joined forces to come up with their best lab demonstration to show weathering,
erosion, and/or deposition. Each group went “shopping” for materials in the
science lab, set up the lab, and presented it to the class.
Cotton balls represent rocks that get washed downstream by a river and eventually end up in a new location. |
Here is what two students had to say about the lab:
Our wreathing, erosion, and deposition lab gave us the
ability to come up with a lab by ourselves. Instead of us following someone
else’s steps, we got to create our own steps! It was really fun and I hope we
could do something like it again! It was challenging, but that’s what made it
fun! See, what we did was, we got to come up with a way to show weathering,
erosion, or deposition. Then we got to show it to the whole class! It was like
an exciting way of learning about science! –Taylor
My group made our science demonstration
for erosion and deposition. We compiled our ideas. One person’s idea was to
have a paper towel tube with sand in it and pour water into it which would
demonstrate erosion because as our teacher taught, erosion is when something
like sand is picked up and moved to a new location. I thought that if we added
a tank and some spoons that we could show deposition. So we stacked some books
on top of each other and we did use a paper towel tube with sand in it. Then we poured water into it and left
some behind. After that we had the tube leading to a big bucket with water in
it. We also put rocks in it because we knew that when rock hits water it
releases some sad. When the sand floated to the bottom we knew we managed to
show erosion and deposition. – Zyonne
