Liquid Lens
Source Institutions
In this activity, learners discover that they can create a lens from a water drop. Learners test their lens by looking at words or pictures.
TerrAqua Investigation Column: What is the Land-Water Connection?
Source Institutions
In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.
Buoyant Bubbles
Source Institutions
What keeps bubbles and other things, like airplanes, floating or flying in the air?
Indicator Paper
Source Institutions
Use grape juice, baking soda, water and vinegar to make acid and base indicator paper! This activity contains a recipe and instructions for the indicator paper.
Bake Ice Cream in Your Oven
Source Institutions
In this a hands-on activity, learners explore how to put ice cream in an oven without it melting. Ideas in this activity include insulation and cooking.
Potato Straw
Source Institutions
In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.
Nature of Density
Source Institutions
In this activity learners will explore the concepts of density and matter in their quest to answer one simple question-will it sink or will it float?
Rollin’ Rollin' Rollin'
Source Institutions
In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.
Rain Machine (Solar Still)
Source Institutions
In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.
Mystery Sand
Source Institutions
In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.
Rolling Action Art
Source Institutions
In this activity, learners of all ages will roll a ball coated with paint to artistically visualize the motion of the object.
Zoom-A-Rang
Source Institutions
In this activity, learners design and build a Zoom-a-rang using everyday materials. Experiment with different materials and Zoom-a-rang designs to see how they fly.
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.
Fizzy Fun
Source Institutions
In this activity, learners test what happens when they put baking power on different frozen liquids.
Homemade Play Dough
Source Institutions
In this sensory activity, young learners explore chemical reactions by making their own play dough from home.
Go with the Flow
Source Institutions
In this activity, learners discover how hard their hearts work to pump blood.
Radial Chromatography
Source Institutions
How many colors make black? Gather as many water soluble black markers as you can find.
Soaring Satellites
Source Institutions
Using a vertical wind tube and using simple materials, individuals and groups attempt to design a "satellite" that floats for at least 5 seconds.
Stethoscope
Source Institutions
Make a copy of the first stethoscope with only a cardboard tube! René Laennec invented the first stethoscope in 1819 using an actual paper tube!
