You don't have to have expensive science equipment to engage children in meaningful science activities. In fact, you don't have to spend much money at all. In this blog post I'll share with you five items that you may already have in your kitchen. If you don't have them already, you can find them in grocery stores and dollar stores for sure.
1. Baking Soda
Baking soda is an inexpensive item that you can buy in the grocery store. I often see it for less than $1.00 per box. Not only does baking soda absorb bad odors in your refrigerator, it can be used to make volcanoes (vinegar + baking soda), trendy bath bombs, and elephant toothpaste.
Vinegar is another inexpensive item that can be purchased in large quantities. In addition to making volcanoes with vinegar, you can use vinegar to rubberize chicken bones and even dissolve the shell off of a chicken egg to see what is inside!
Cornstarch is the main ingredient in many slime recipes, which are the rage among children right now. Cornstarch can also be used to make oobleck and quicksand.
4. Coca Cola
Coca cola is highly acidic and can be used in many dissolving experiments. For example, you can take tarnished and dirty coins and soak them in Coca Cola all night. In the morning, they will be shiny and new.
Eggs can be used in a variety of experiments. You can use eggs to teach about dental care and the need to brush teeth. Simply soak some eggs over night in coffee, tea, Coca Cola, etc. over night. In the morning they should be discolored. Take a toothbrush and toothpaste and try brushing the eggs' surfaces. Were they easy to clean? Try soaking the eggs again for two or three nights. How much harder was it to clean the surfaces? Were you able to completely them? What does this teach us about taking care of our teeth?
