Elementary School Chemistry Science Projects (22 results)

An experienced chemistry professor used to say that it took about one explosion per week to maintain college students' attention in chemistry lectures. At that rate, we'd get in pretty big trouble with a lot of parents and teachers! Don't worry, our list of chemistry science and engineering projects still has lots of bubbles, fizzes, bangs, and color changes for you to explore.

Alka-Seltzer® tablets fizzle furiously when dropped into water. The moment the tablet starts dissolving, a chemical reaction occurs that releases carbon dioxide gas. In this science project, you can even measure how long and loudly your tablet fizzes using Google's Science Journal app. Do you think you can make Alka-Seltzer fizz faster or more loudly by changing the temperature of the water? How big of a difference in the rate of a chemical reaction can temperature make? Read more

Science Fair Project Idea
You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar or salt) that are dissolved in the water? Do they boil off too, or do they stay behind? Read more
