Children and adults alike are fascinated with the night sky. Living in the city makes stargazing a bit difficult and this activity helps to identify the problem and be able to determine best viewing locations. The Science Buddies resource is well organized with a through introduction to our topic, light pollution, and other terms that will help us learn more along the way. The questions are thought provoking and can be used as before and after measures. The materials and equipment are very easy to come by. It is very important to use a toilet paper tube because of how we can use that sample size to calculate how many stars are in the night sky. It may sound random that they choose the number 104, but in step 10 of the procedure, it gives a link to another resource about Counting Stars by Dave Weinrich. If you click on the link and scroll down to the background information, the second and third paragraph describe the mathematical reason behind the number. What is great about this activity is that it can be done over the course of many days so that many locations can be visited. The words used in the procedure convey the message that the students are taking relevant scientific data “in the field.” I feel this really help them envision themselves in the STEM career. If for some reason you cannot leave the house, you can combine this activity with the Create a Flashlight Constellations activity available on this site and make notes about how visible the constellations you create are in your house with the lights on and off.
