What is an easy and not too expensive science project during the summer for students?

Answer 1

You can always go for the trademark volcano. It just requires some baking soda, and a homemade paper machete model of a volcano itself.

Answer 2

Germinating seeds at home can be easy and fun to do. Start with paper towel, a water sprayer, some seeds (bean sprouts work really weel) , a small bag of potting soil,some cold cups and a large zip lock bag.

Pick your seeds (6 -10); lay out 2 sheets of paper towel and put the seeds equal distance across the first towel. Spray with water to moisten and lay the second paper towel on top. Spray again. Fold the towel like a burrito and put into zip lock bag and seal. Place in warmish, dark area several days.

Pull out the zip lock and check your seeds. If they have started to sprout, there will be little tails at their bottoms. Fill your cold cup up about 3/4 with potting soil and dampen. Place the seeds, root down, in the cup (maybe 4 per cup.) Poke a few holes in the bottom of the cup for drainage and place in a second cup. Put the cup close to a window, spray every day and watch your seeds grow!

If you want to transplant, take the seedlings outside during the day to 'harden' and bring back in. When you feel they are ready, they can come out of the cold cups and be placed in more potting soil in an outdoor pot. Viola! You have a new plant! CW
