That Sinking Feeling
Source Institutions
In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.
Gelatin Used for Drug Delivery
Source Institutions
In this activity, learners discover how gelatin can be used as a medium for drug delivery. Learners create colored gelatin and then cut out pieces of the gelatin to simulate medicine (pills).
Cold Metal
Source Institutions
In this activity, learners discover that our hands are not reliable thermometers.
How Animals Stay Warm
Source Institutions
In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl
A Crayon Rock Cycle- Metamorphic
Source Institutions
This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.
Exploring Moisture on the Outside of a Cold Cup
Source Institutions
In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.
Leaf it to Me
Source Institutions
In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.
Give and Take
Source Institutions
In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.
A Feast for Yeast
Source Institutions
In this activity on page 6 of the PDF (Get Cooking With Chemistry), learners investigate yeast. Learners prepare an experiment to observe what yeast cells like to eat.
Cool It!
Source Institutions
In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!
Hot Stuff!: Investigation #2
Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.
Making An Impact!
Source Institutions
In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.
Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
Nuclear Fusion
Source Institutions
This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.
Condensation
Source Institutions
In this activity, learners explore the process of condensation.
A Crayon Rock Cycle - Igneous
Source Institutions
This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.
Send Secret Messages
Source Institutions
In this activity, learners write a secret message in "invisible ink" and then use chemistry to view the writing.
Make Your Own Deep-Sea Vent
Source Institutions
In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.
Let's Go Ice Fishing
Source Institutions
In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.
Super Shrinkers
Source Institutions
In this activity on page 14 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners turn plain pieces of recycled plastic into shrunken works of art.
