Making soap you can use

What is the difference between making inferences and making observations? Young climatologists refer to a PowerPoint to make observations on each slide. They record their observations in a provided worksheet before drawing a...

Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science instructional activity introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a...

In a sweet simulation, junior geneticists examine the chromosomes of a fictitious Reebop marshmallow animal, combine chromosomes to produce offspring, and then make a model of the resulting Reebop baby. Phenotypes include number of...

How do you put something as large as the universe in perspective? Use a series of scale experiments. Classmates collaborate around four experiments to examine the scale of the earth-moon system, our solar system, the Milky Way galaxy,...

You may not be able to take a field trip to the moon, but that doesn't mean your class can't study moon rocks. Using graham crackers as the moon's bedrock and powdered donuts as micrometeorites, young scientists simulate the creation of...

Scientists could measure the diameter of the sun before they knew its distance. Scholars construct a simple mirror box to measure the diameter for themselves. They compare this measurement with the official size, listed in a textbook,...

Give young geologists an up close and personal look at volcanoes with a series of hands-on earth science lessons. Whether they are investigating the properties of igneous rocks, building their own volcanoes, or making fudge to model the...

Water is common? Not really! Learn how the polarity of the water molecule gives it tremendous properties that make is quite unique in the universe. Learners will understand surface tension, adhesion, and cohesion, as well as why these...

I can get more water to stay on a penny than you can! Collaborative pairs determine the volume of liquids that can be contained on the surface of copper pennies and plastic coins. The pairs analyze their results using graphs and go on to...

Skeletons may not be able to speak, but they can still tell us a lot. High schoolers watch a short video about the ways biological anthropologists can use a skeleton's bone structure to determine age, gender, place of birth, and social...
