Our goal for this experiment was to find the index of refraction of water. First of all, we had a tank of water and inside a lego toy sitting in the bottom of the tank, then we pointed a laser through air and through the water hitting straight at the toy. In order for us to be able to see the light through the air and water, we used a fog machine and we created a layer of fog around the tank thus making it easier for us to see the light and collect our data.
This Lab Report, sponsored by Apologia Science, explores the properties of water with a simple experiment for you to try at home. For more water property experiments, see this past Lab Report on Testing The Properties Of Water.
Spinning Match - Table Trick - When you cautiously balance a matchstick on the rim of a coin that has also been precariously balanced onto another coin, it might sound like rotating the matchstick will cause it all to come tumbling down.
This project is easy to achieve with basic kitchen materials and it’s embedded with all sorts of opportunities for introducing the scientific method (in short: asking scientific questions, making predictions, and conducting an experiment).
Science isn't something that necessarily needs to be done in the closed quarters of a lab. Many of the most brilliant experiments can be done in your own home and literally cost you almost nothing to make!
