I remember going to the school science fair as a child and looking at the erupting volcano in awe. It was indeed fun to execute a few of my own experiments at the science fairs in school.
Come to think of it, science experiments can be quite fun & educational for children in elementary school mainly because they provide an element of surprise and a sense of achievement after having conducted one successfully.
Some QuickSchoolers took 30 minutes off today to run some internet searches on popular projects for science fairs. Here’s a few cool experiments that we will soon be trying out ourselves:
1. How much energy is stored in a peanut?
This experiment uses a (fire) lit peanut to heat up 1/2 a cup of water. Students can then approximate how much chemical energy was stored in the peanut.
This experiment will require adult supervision as needles & fire is involved.
2. Making a model arm
We use it every day and probably do not even think about how it works. The human arm is a complex structure made up of bones, joints, ligaments, and muscles. But how does it all work? What makes us pick up that cup of coffee or throw that football to an exact area fifty yards away? This project will go deep into the human arm and how it works.
From sunrise to sunset, shadows of buildings, trees and other objects move slowly, but continuously. In the northern hemisphere, shadows cast west in the morning, north at noon time and east in the late afternoon. Knowing the direction of shadows is very helpful for telling the time and the directions. To tell the time using the shadows we use sundials or sun clocks. Sundials have been used for centuries to tell the time.
4. The good old erupting volcano
For those who still want to try out this experiment, knock yourself out!
Have fun teaching! =]
