The Water Drop Project

That is living in the water? Groups of two to three view pond water with microscopes in order to find microorganisms. They draw pictures of the ones they find in their slides.  The groups compare their drawings to pictures of common pond...

Water is essential for life—and understanding the importance of clean drinking water is essential in understanding sustainability! Show your environmental science class the basics of water testing and treatment through a week-long...

Have individuals wash their hands with soap and water, give one of them a yeast-covered piece of candy, and then have him shake hands with the person next to him. Handshakes continue down the line until everyone in the class has had...

How are maps like fish? They both have scales. The chapter includes six different activities at three different levels. Scholars complete activities using natural resources, learn how to read a map, see how to make a compass rosette,...

Investigators use indirect evidence to guess what is occupying a sealed box. You could also use a set of plastic Easter eggs to encase the unknown items. Another terrific activity involves having students drop a pencil on a sheet of...

Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...

Have you ever wanted to know the true structure of E.coli? Does the thought of peering into its "small world" sound exciting? Here is a lesson that allows pupils the ability to do just that. Blossoming microbiologists use microscopes to...

Get to know H2O! It's the most popular molecule in the world, but how well do you know it, really? An interview-style video gets to the bottom of our common knowledge about water, asking random subjects for the formula and what the...

An exhaustive set of "lecture notes" on various topics in thermal physics (including thermal expansion). Explanations are well done and more interesting than most. Includes both a mathematical and conceptual treatment of topics. Humor,...

If you need a straightforward and comprehensive organic chemistry exam, check this one out. Chemistry pupils identify functional groups in molecule diagrams, draw a Lewis structure, fill in a table about molecular shape, predict boiling...
