Optional Laboratory: Forest Volume Cruise

Don't be so dense that light bends around you; study the relationship between mass and volume instead. Young chemists measure the density of a variety of liquids and solids. A reading passage and analysis questions introduce pupils to...

Make sure that campfire is completely out before packing up your campsite! A straightforward and informational worksheet encourages learners to match pictures to the sequential steps needed to safely extinguish a campfire, and to note...

There otter be a better way. As a class, groups work together to create a food web based on the organisms in the kelp forest. Budding scientists watch a video on the kelp forest to see how the organisms create a food web and hear about...

Students explain the components of fire, explain how forest fires impact man and the environment, analyze data in order to recognize areas that are at risk for forest fires, make recommendations based on research.

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Although this lesson is directed at a chemistry class, all laboratory classes require the use of metric measurement. Here is a half-hour video introduction to measurement systems and a thorough teaching about the base-ten metric system...
