Kids Science Experiments
If you remember, part of my goals for the new year are to start doing more science experiments with my kids, so that I can help foster their love of science. I am going to attempt to do new kids science experiments every week, and I figure it might be fun for all of you to do them with your kids as well!
Make an Egg Float in Salt Water
What you’ll need:
- One egg
- A tall drinking glass
- Pour water into the glass until it is about half full.
- Stir in lots of salt (about 6 tablespoons).
- Carefully pour in plain water until the glass is nearly full (be careful to not disturb or mix the salty water with the plain water).
- Gently lower the egg into the water and watch what happens.
Salt water is denser than ordinary tap water, the denser the liquid the easier it is for an object to float in it. When you lower the egg into the liquid it drops through the normal tap water until it reaches the salty water, at this point the water is dense enough for the egg to float. If you were careful when you added the tap water to the salt water, they will not have mixed, enabling the egg to amazingly float in the middle of the glass.
If you’d like to try more kids science experiments, check out this book… Or you can wait and see what I come up with next week!
Feel free to email photos to firstname.lastname@example.org of your kids enjoying their science experiments.
