One of the coolest I've ever seen is a substance called "oobleck".
easy
because their cool, low maintenance, cheap and easy to feed
a good science experiment for 6th graders that is fun is making insta snow its fun and inexpensive
Vinigar and baking soda, coca cola and mentos. By the way is your name carl?
Honestly, I don't think you could do an experiment in one day. Science experiments should take longer than one day. You wouldn't have much time to do anything for an actual science project if you did it in one day. -Taniya
Volcano one. Vinegar and baking soda.
A really easy experiment is; you get a hairdryer, you put a ping-pong ball on where the air comes out, turn the hairdryer on high, and the ball will hover! Amazing!
What I did for a 4th grade, was a balloon-powered car. For older grades you want to make it cool and a different project.
My experiment of my science project is called what makes ice melts fastest I come this experiment because I want to know how does sun and ice help the ice help the ice sidewalk during winter time for this experiment you'll need ice salt and control...
One type of experiment that is easy for kids to explore is a floating egg in water. By adding salt, the salty water is denser and pushes the egg up, causing it to float. This explores density and is easier for kids to understand. Another type of experiment is the coke and mentos experiment. This shows kids how the bubbles in soda react with something that has a lot of little 'dimples' in it.
It is easy and cheap to mine and easy, cheap and versatile to use.
Most likely. You just need add Freon. Real easy an cheap fix. If your Freon is full and your AC still not working. Probably gonna be your AC pump. That's not a cheap fix.
