Lungometer
Source Institutions
In this environmental health activity, learners investigate their own vital lung capacities.
Hot Stuff!: Testing Ice
In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.
Light Maze
Source Institutions
In this activity, learners will explore light with reflective surfaces. Learners will make predictions and share their observations as they experiment with directing a beam of light.
Patterns and Relationships: Struts 'n Stuff
Source Institutions
In this math lesson, learners identify the relationship between the number of sides in a regular polygon and the number of struts needed to make each polygon rigid.
Germination Station
Source Institutions
In this botany activity, learners will create an experiment about seed germination. This activity gives students an opportunity to explore how seeds germinate and react to surrounding conditions.
Making a Simple Astrolabe
Source Institutions
In this activity, learners make an astrolabe, a device used for measuring altitude, including the height of objects in the sky.
Copper Caper
Source Institutions
In this activity, learners conduct an oxidation experiment that turns old pennies bright and shiny. Learners soak 20 dull, dirty pennies in a bowl of salt and vinegar for five minutes.
What's So Special about Water: Surface Tension
Source Institutions
In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.
Hot Cans and Cold Cans
Source Institutions
Learners apply their knowledge of heat transfer to design two cans - one that will retain heat and one that will cool down quickly.
Measure the Pressure II: The "Dry" Barometer
Source Institutions
In this activity, learners use simple items to construct a device for indicating air pressure changes.
Color-Changing Carnations
Source Institutions
Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.
Fly a Leaf
Source Institutions
In this outdoor, windy day activity, learners "fly" and race leaves along a line to discover which types of leaves catch the most wind. Which leaves are the best fliers? Why?
Bank It!
Source Institutions
This simple but open-ended math game introduces basic probability concepts using coins and dice. Players roll the dice and collect coins to match the number rolled.
How Sweet It Is
Source Institutions
In this activity (4th activity on the page), learners use their sense of smell to rate and arrange containers filled with different dilutions of a scent (like cologne or fruit juice) in order from wea
Heavy Metal
Source Institutions
In this activity (on pages 25-31 of PDF), learners soak sponges with different amounts of plaster of paris to simulate different levels of calcification in bone formation.
Active Graphs
Source Institutions
In this activity, learners track their movements with jumping and leaping graphs.
Good Vibrations
Source Institutions
This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.
Light as Air
Source Institutions
In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.
Make Your Own Barometer
Source Institutions
In this weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.
Ready to Observe: Enhance Your Telescope Experience
Source Institutions
This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.
