Edible Model of the Sun
Source Institutions
In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.
DNA Extraction
Source Institutions
In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.
Newton's Laws Demonstrations
Source Institutions
In this collection of demonstrations, learners explore Newton's Laws of Motion.
DNA From an Onion
Source Institutions
In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.
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.
Membrane Permeability with Beets
Source Institutions
In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.
Lima Bean Bacteria DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from lima bean bacteria. This experiment requires the use of a centrifuge (not included in cost of materials).
Casting and Molding
Source Institutions
This activity was designed for blind learners, but all types of learners can explore the process used to cast and mold molten metal, glass, and plastics.
Thymus DNA Extractions
Source Institutions
This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.
Making Connections: What You Can Do To Help Stop Global Climate Change
Source Institutions
In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.
Guar Gum Slime
Source Institutions
In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.
What Molecules Make the Holes in Bread?
Source Institutions
In this activity, learners will discover why there are holes in bread.
Acids & Bases
Source Institutions
In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.
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.
Molecular Gastronomy: Use Self-Assembly to Make a Dessert Topping
Source Institutions
Molecular gastronomy is the scientific study of food preparation. Learners use self-assembly techniques to create edible capsules of chocolate syrup (food grade ingredients are required).
Build Your Own Solar Oven
Source Institutions
Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.
“Chips” Off the Old Block?
Source Institutions
In this activity, learners bake cookies by following different recipes to better understand genetic mutations. Everyone in the group bakes the same type of cookie: chocolate chip.
Wheat Evolution: Dough Washing
Source Institutions
In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.
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.
