Source Institutions
In this activity, learners create a cool floating animal using the science of magnetism. Learners discover what happens when a piece of magnetic metal enters a magnet's field.
It's the "Rain," Man
Source Institutions
In this weather forecasting activity, learners use common materials to construct a rain gauge and measure daily, monthly, and yearly rainfall.
Curious Crystals
Source Institutions
Learners carefully look at four known household crystals.

In this math game (Page 17 of the Are You Game? PDF), learners investigate probability by tossing coins.
Number Patterns
Source Institutions
In this lesson, learners are challenged to discover the relationship among six numbers.
Moving Without Wheels
In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.
Safe Food Preparation
Source Institutions
In this activity about food safety and nutrition, learners investigate safe food preparation by making fruit ice cream.
Food Webs
Source Institutions
In this activity, learners construct possible food webs for six different ecosystems as they learn about the roles of different kinds of living organisms.

Source Institutions
This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d
Shapes and Colors and Textures, Oh My!
Source Institutions
This is an activity about discovering the colors and beauty of nature. Learners will spend time outdoors, matching paint chip samples, colored paper, or colors of clothing to those found in nature.
Create a Pasta Population Map
