6th Grade Science Experiments

6th grade science experiments are fairly easy to come by. Simply home in on a topic that interests you and away you go. Sixth grade science projects are not expected to be original; it’s perfectly okay to do an experiment that has been done before. The judges simply want to see that you have put some effort into your project and have taken the time to create a decent presentation for it.

I recommend these printable science project plans for K-12 for hundreds of great project blueprints and this step-by-step guide for doing an award winning science fair project. Also be sure to check out these fun science kits as a fast, simple way to get started on your science experiment.

Experiment: Does an egg float or sink in water? What if we change the density?
Category: Chemistry
Ages: Middle School

One sixth grade science project that is a lot of fun is to see if an egg will float when placed in water, and what will happen to the egg if you change the density by adding sugar or salt. For this experiment, you will need two glass jars that are large enough to hold a few cups of water each, two eggs, some salt, some sugar and some water.

First, you can put a few cups of water into each jar, and then place one egg into each jar of plain water. Do the eggs float in the water or sink to the bottom? Next, take one jar and add a teaspoon of sugar. Did it make the egg float? (Or sink if the egg was already floating?) Add a few more teaspoons of sugar, does it change at all? Take the other glass jar with the egg in it and add a teaspoon of salt. Did it make the egg float? (Or sink if the egg was already floating?) Make sure to record and compare your results.
