This is Carlsbad Caverns. What are the main chemicals involved in the formation of all of those beautiful, flowstone structures?

Color of a Flame

Have you ever wondered why a candle flame is yellow? And if you look carefully, you will see that the very bottom of the flame is blue! Why would that part of the flame be a different color? The best way to find out is to do some careful experimentation.


This experiment uses fire. Be very careful and safe.

What is Smoke?

I have been doing shows on the Science of Fire, so I thought we would do a fire related experiment.

As with all experiments that use fire, BE CAREFUL AND SAFE. Follow proper safety procedures and think about things before you try them. You should also have another adult with you, just in case you have an accident. That way, you have someone else to blame.

For our experiment, we are going to take a look at smoke. What is smoke made of? To find out, you will need:

A Hot Change

We have taken a brief look at an endothermic process, seeing that dissolving epsom salts in water lowered the temperature of the water. This week, we will examine a process that is exothermic, which means that it gives off heat. To try this, you will need:

The Science of Spit

This experiment comes from our cat, Mawra. She is a delightful cat, but when she is very happy, she drools. She was happily sitting in my lap while I was thinking of topics for this week's experiment. That's when it hit me. (Literally) Saliva! To learn more about spit, you will need:

Cleaning the Silver

This week's experiment is a simple chemistry experiment that you can use to clean the silver. Be sure to get permission before doing this. While it may seem a nice surprise, some silver is not meant to be cleaned, so be sure to ask first.

Peroxide Bubbles

This time we are going to talk about a very important substance, oxygen. Oxygen is the third most abundant element in the universe, coming after hydrogen and helium. About 20% of the air around you is made up of oxygen, and it is vitally important to life on Earth. It is also important for combustion, and that is what we will explore today.
