Water Walk
Source Institutions
Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.
Solar Water Heater
Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.
Water Clean-up
Source Institutions
This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.
Pneumatic Trough
Source Institutions
In this activity, learners build a "pneumatic trough," a laboratory apparatus used for collecting pure gas samples over water.
Electrolysis
Source Institutions
Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.
Engineer a Dam
Source Institutions
In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.
Feel the Heat
Source Institutions
In this design challenge activity, learners design and build a solar hot water heater. Their goal is to create a heater that yields the highest temperature change.
Plot the Dot: A Graphical Approach to Density
Source Institutions
In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.
Wind Tunnel Testing
Source Institutions
In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.
Making Sense of Sensors
Source Institutions
In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.
Keep it Cool
Source Institutions
In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.
Life Vest Challenge
Source Institutions
In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.
