Understanding Unfamiliar Units: What is a Light-Year? Teaching the Scientific Method with Effervescent Tablets
Understanding Unfamiliar Units: What Is a Light-Year?
Here’s an activity that gets your students moving while they practice measuring and manipulating units. By putting time and distance traveled into units students can directly relate to, the abstract concept of the light-year is more easily understood. Learn more about this inexpensive, fun activity at the link below.
Teaching the Scientific Method with Effervescent Tablets
In this activity, students learn the scientific method by practicing it. After a thorough introduction to the topic, students participate in an endothermic reaction experiment illustrating each step in the scientific method. An extension activity lets students explore further. Learn more at the link below.

Teacher 2 Teacher Tips  
Better, Safer Flame Tests
When you do flame tests, use cotton-tipped swabs soaked in the salt solutions overnight. Set the swabs out for a few hours before the lab. As water from the solution evaporates off the swabs, salt will begin to crust on them. This makes a better flame test than using wet swabs and is safer than using ethanol. I have even kept the salt solutions in the beakers for a couple of weeks until all the water evaporated and the salt was left behind. At that time, I would scrape off some of the salt and redo the flame tests as a review demo.
