Fragile Waters
Source Institutions
In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.
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.
Water Wire: Electricity Flowing Through Water
Source Institutions
In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.
Pedal Power
Source Institutions
In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.
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.
Bubble Trouble
Source Institutions
In this activity on page 15 of the PDF, learners measure the amount of bubbles that they make using a detergent.
Does Size Make a Difference?
Source Institutions
In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.
Salting Out
Source Institutions
In this activity, learners create a mixture of water, alcohol and permanent marker ink, and then add salt to form a colored alcohol layer on top of a colorless water layer.
Pollution Diffusion
Source Institutions
Learners design their own experiment to investigate how pollution diffuses through ground material.
Potion Commotion
Source Institutions
In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.
Operation Espionage
Source Institutions
In this activity, learners create and reveal secret messages written with invisible ink! The invisible ink is actually a baking soda solution, and the magical revealing liquid is fruit juice.
House Warming
Source Institutions
In this physical sciences activity, learners explore how passive solar design increases energy efficiency.
Breaking Point
Source Institutions
