Power Up!
Source Institutions
In this online game, learners must purchase power plants for their city.
Egg Bungee Jump
Source Institutions
In this activity, learners design a bungee jump for an egg using nylon stockings.
Under Pressure
Source Institutions
In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.
Mirror Messages
Source Institutions
In this activity, learners use mirrors to write secret messages to a friend. Use this activity to explore letters, optics, and/or symmetry.
Equatorial Sundial
Source Institutions
In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.
Don't Stop for Hitchhikers
Source Institutions
In this activity, learners role-play the part of lake inhabitants and the aquatic exotics who displace the native species.
Harmless Holder
Source Institutions
Have you noticed the plastic rings that are used to hold six-packs of soda? Those rings are great for carrying cans, but they're real trouble when they become trash that animals can get tangled in.
Avogadro's Bubbly Adventure
Source Institutions
In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.
Tempest in a Teacup
Source Institutions
In this hands-on activity, learners determine the types of chemical reactions achieved when combining different household products.
Critical Load
Source Institutions
In this activity, learners explore the concepts of structural engineering and how to measure the critical load, or the maximum weight a structure can bear.
Hanford at the Half-Life Radiation Calculator
Source Institutions
This quiz lets you estimate your annual radiation exposure.
Handheld Water Bottle Rocket & Launcher
Source Institutions
In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.
Using a Sundial
Source Institutions
In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.
Pulleys and Force
Source Institutions
In this activity, learners explore the concept of force and how pulleys are used in everyday life to make work easier.
Mass, Area, Volume
Source Institutions
In this activity (page 18 of PDF), learners will measure the volume of impact craters created by projectiles of different masses.
Measuring the Wind
Source Institutions
In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.
Sidewalk Chalk
Source Institutions
In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.
Moldy Jell-O
Source Institutions
In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.
Composting: A Scientific Investigation
Source Institutions
In this activity, learners conduct a scientific investigation involving decomposition and discover that the life cycle of trash is affected by its organic or inorganic nature.
Super Sleuths
Source Institutions
In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection
