Analyzing Tiny Samples Using a Search for the Beginning Mass Spectrometry
Teach the basics of mass spectrometry with a hands-on lesson. The fourth in a series of six lessons explores how mass spectrometry measures the ionic composition of an element. Learners then compare and contrast relative abundance and...

Towers of the Lost City
Middle school marine scientists compare the pH change in distilled and saltwater as acetic acid is added one drop at a time. Then they compare the pH change in both when sodium hydroxide is added. This experiment demonstrates the...

Changing Planet: Withering Plants - Stressing Over Lost Water
Expectant earth scientists examine the bottom side of a leaf and learn the role of the stomata. They consider the gas exchange that occurs through these structures and relate how the climate is changing to its impact on food crops. This...
Science Friday
Mineral Madness
Science does not need to be as hard as a rock. Pupils test 10 different minerals to determine their properties. The learners observe luster, streak, hardness, and fluorescence for each specimen. Afterwards, they compare and contrast the...

Building a Barometer
Forget your local meteorologist — build your own barometer and keep track of the weather with an activity that provides directions to build a barometer out of a narrow necked bottle, a glass, and some water. Using their barometer,...
Discovery Education
3D Printing Robots
What is water worth to you? The answer probably depends on many different variables. Learners explore the value of water in space and what it takes to transport the resource to locations in a galaxy far far away. They then consider...

India and Pakistan: Rivals from Birth
Seventh graders, after being divided into two groups, are assigned either Pakistan or India. They conduct research using the Internet, reference books, and magazines. The class compares and contrasts the two countries to find sources of...
Curated OER
Animals and Humans
Students identify the functions of various body parts. They participate in the "Head, Shoulders, Knees, and Toes" song, draw a picture of themselves and other mammals, and create a traced outline of their body that they add features to....

Investigation: Heat it Up!
This demonstration of solar ponds can be used in an earth, environmental, or physical science setting. Lab groups set up a solar pond and model how it is able, due to a salt concentration gradient, to maintain heat for future use.

Thirsty Rocks: Please "Porous" a Drink!
A simple activity goes a long way in demonstrating the property of porosity to your rock hounds. They will mass a specimen of dry sandstone and then soak it in a pre-measured amount of water. After seven minutes, they once again measure...
