Make a Lake
Source Institutions
Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?
Community Wind Project
Source Institutions
In this thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community.
Weather Vane
Source Institutions
In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.
Water Bugs
Source Institutions
Some bugs can walk on the surface of a lake, stream, river, pond or ocean.
Kepler Paper Model
Source Institutions
In this activity, learners build a paper model of the spacecraft and photometer (telescope) used during NASA's Kepler Mission.
Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
Automotive Emissions and the Greenhouse Effect
Source Institutions
In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.
Lift Off!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.
Bridge Building
Source Institutions
This is a quick activity (on page 2 of the PDF under Hockey Sticks Activity) about how the arrangement of carbon atoms determines carbon's different properties.
Trail Impact Study
Source Institutions
In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.
Exploring Ultraviolet (UV) light from the Sun
Source Institutions
In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.
Exploration Vehicles
Source Institutions
Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).
X-Ray Spectra
Source Institutions
In this activity, learners use simple materials to simulate the effect of X-rays in a safe way. Learners place a piece of window screen over a box and a cardboard pattern on top of the screen.
Cleaning Water with Dirt
Source Institutions
In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.
Sand Castle Saturation
Source Institutions
In this activity about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.
MarsBound!: Mission to the Red Planet
Source Institutions
MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.
Oil Spot Photometer
Source Institutions
In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
Windmills
Source Institutions
In this physics activity (page 8-9 of the PDF), learners will explore wind energy. They will build their own windmill and see how energy from wind can be converted into a useable form.
We Have Capture!
Source Institutions
Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.
Trail Construction
Source Institutions
In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.
