Chromatography Can Separate!
Source Institutions
In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.
Our Sense of Sight: Color Vision
Source Institutions
In this activity, learners investigate color vision as well as plan and conduct their own experiments.
What is Nanotechnology?
Source Institutions
In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.
There’s No Place Like Home!
Source Institutions
In this activity, learners make their own bug boxes and test the habitat preference of selected "minibeasts" (bugs).
Polymers are Chains (K-2)
Source Institutions
In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.
Leaves: Extracting Pigments
Source Institutions
In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.
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.
Toy Chemistry
Source Institutions
In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.
Kites
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.
Disappearing Statues
Source Institutions
In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.
Heart and Lungs
Source Institutions
In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.
Paper Chromatography with Leaves
Source Institutions
In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.
Operation Espionage
Source Institutions
In this activity, learners create and reveal secret messages written with invisible ink! The invisible ink is actually a baking soda solution, and the magical revealing liquid is fruit juice.
Making Recycled Paper
Source Institutions
In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.
Light is Made of Colors
Source Institutions
Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.
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.
Size, Scale and Models
Source Institutions
In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.
Invisible Ink
Source Institutions
In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a
Environmental Chemistry
Source Institutions
In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.
Sunny Day Painting
Source Institutions
In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.
