What is a good, easy Science project for a 4th grader?
http://www.all-science-fair-projects.com… has good ones. For younger kids, I’d recommend something easy. When I was in 3rd grade, I did this “magic trick” where I changed colors of the liquid to pink, blue, and green. I can’t really find that project info on Google, but I found something related that you might like: http://www.funsci.com/fun3_en/acids/acid… Hope this helped. 🙂 I am now in 7th grade and I based my last Science project on “which gas is the heaviest?”, but you need to know how to make gases for that one and I don’t think a 4th grader can do that as easily without a science lab full of materials.
Salt increases the density of water. Add four to five tablespoons of salt in a glass of water stir it nicely and float an egg. Also add little more luke-warm fresh water and check, the egg will float in-between the salt and the water. Try using sugar or flour in the water the egg will sink. Which water is good for plants can be made as a project by selecting a pot with some seeds; one pot can be watered with tap water, the other pot to be watered with only rain water. Check the growth for seven weeks; the rain water watered pot is better. Will plants grow with a liquid other than water can be done in an effective project by selecting four pots, Water the first pot with water, second one with vinegar, third one with orange juice and fourth one with milk. The result is the one with water grows the maximum, the one with vinegar dies as it is an acid, the one with orange juice and milk also grows but nowhere near as much as the pure source.
