Gummy Shapes
Source Institutions
In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.
Ripening of Fruits and Vegetables
Source Institutions
In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.
Recycle Your Own Paper!
Source Institutions
In this activity (page 2 of PDF under GPS: Garbology Activity), learners will prepare sheets of homemade recycled paper from several different source pulps.
Biodomes Engineering Design Project
In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.
Carbon Dioxide Removal
Source Institutions
In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.
Colored Shadows Investigation
Source Institutions
This activity (located on page 3 of the PDF under GPS: Light and Color Activity) is a full inquiry investigation into mixing colors with light.
Colorblind Dogs
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Colorblind Dogs) is a full inquiry investigation into dogs' ability (or inability) to see color.
Science of Sunblock
Source Institutions
This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl
Coverslip Traps
Source Institutions
In this activity, learners use coverslips to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.
The Decayed Pumpkin
Source Institutions
In this "Sid the Science Kid" activity from Episode 106: My Mushy Banana, learners explore the effects of decay by comparing and contrasting something (an old pumpkin) that's decayed with the same thi
Sweat Spot
Source Institutions
In this activity, learners use a chemical reaction to visualize where moisture forms on the body.
Wheat Evolution: Dough Rising and Baking
Source Institutions
In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.
No bones about it!
Source Institutions
This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.
Solar Water Heater
Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.
Illuminating Luminescence
Source Institutions
In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.
How Fast Can a Carrot Rot?
Source Institutions
Learners design their own experiment to determine conditions that either help or hinder the decomposition of carrots by soil microbes.
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.
Self-Assembling Dessert Toppings
Source Institutions
This is an activity (located on page 3 of the PDF under Self-Assembly Activity) about self-assembly, the ability of molecules to assemble themselves according to certain rules.
No It's Snot
Source Institutions
In this health activity (on page 3 of the PDF), learners will learn about the body‘s defenses against invasion from tiny particles.
Water Walk
Source Institutions
Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.
