Extreme Sounds
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Extreme Sounds) is a full inquiry investigation into sound.
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.
Earth's Energy Cycle: Albedo
Source Institutions
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.
Exploring How Liquids Behave
Source Institutions
Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.
Heating and Cooling of the Earth's Surface
Source Institutions
Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.
Build Your Own Robot Arm
Source Institutions
In this lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.
Film Canister Farming
Source Institutions
In this hands-on botany activity, learners sprout vegetables in film canisters.
Number Sense and Computation: Soak It Up
Source Institutions
In this math lesson, learners compare products to determine the best product.
How Quick Are Your Responses?
Source Institutions
In this activity (on page 134 of the PDF), learners explore reaction time.
Mystery Powders
Source Institutions
In this activity on page 2 of the PDF (Get Cooking With Chemistry), learners conduct chemical tests on certain powders used in cooking.
Evaporation
Source Institutions
This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.
Cover Your Mouth
Source Institutions
In this health activity (page 3 of the PDF), learners will discover why covering their mouth and nose while sneezing is so important.
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.
Comparing the Density of Different Liquids
Source Institutions
Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.
Membrane Permeability with Beets
Source Institutions
In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.
Clean Water: Is It Drinkable?
Source Institutions
In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.
Big Wave
Source Institutions
This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.
Insulation Station
Source Institutions
In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.
Rocket Reactions
Source Institutions
The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.
A Swell Activity with Beans
Source Institutions
In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.
