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.
Mold Growth
Source Institutions
In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.
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.
Spaghetti Bridge
Source Institutions
In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.
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.
ZOOM Glue
Source Institutions
In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.
Exploring at the Nanoscale
Source Institutions
This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.
Make Your Own Batteries!
Source Institutions
This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.
Diffusion of Water with Gummy Bears
Source Institutions
In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).
Trebuchet Toss
Source Institutions
In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.
Column Chromatography
Source Institutions
In this activity, learners separate the components of Gatorade using a home-made affinity column.
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.
Leaning Tower of Pasta
Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.
Multi-Variable Relations: Stressed to the Breaking Point
Source Institutions
In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.
A Simply Fruity DNA Extraction
Source Institutions
In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they 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!
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.
Milli's Insulation Investigation
Source Institutions
In this activity on page 2 of the PDF, learners test different materials to find out which is the best insulator.
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.
Milk Plastic
Source Institutions
In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.
