Wheat Evolution: Sedimentation Testing
Source Institutions
In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.
A Recipe for Air
Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.
Nano Ice Cream
Source Institutions
In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.
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.
Extruding
Source Institutions
This activity was designed for blind learners, but all types of learners can explore the process of extrusion used to produce pipes and wires in industry.
Making a Battery from a Potato
Source Institutions
In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.
DNA Nanotechnology
Source Institutions
In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.
Gumdrop Chains and Shrinky Necklaces
Source Institutions
In this activity, learners thread gumdrops together to make a model of a polymer.
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!
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.
Spaghetti Strength
Source Institutions
In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.
The Nose Knows!
Source Institutions
In this activity on page 9 of the PDF, learners test how flavoring extracts move through the walls of a balloon.
Cartesian Diver
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.
Egg-stra Strength
Source Institutions
In this physics activity, learners will investigate the strength of egg shells.
Dancing Cereal
Source Institutions
In this quick activity (on page 2 of the PDF under GPS: Body Electricity Activity), learners will observe how dry breakfast cereal appears to dance when it gets close to a balloon charged with static
Exploring Fabrication: Gummy Capsules
Source Institutions
In this activity, learners make self-assembled polymer spheres.
Starch Breakdown
Source Institutions
Learners use Benedict’s solution and heat to test for the presence of simple sugars in glucose, sucrose, starch, and starch combined with amylase.
Soda Geyser
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.
Gumdrop Dome
Source Institutions
In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.
Gelatin Prism
Source Institutions
In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.
