Measure the Pressure II: The "Dry" Barometer
Source Institutions
In this activity, learners use simple items to construct a device for indicating air pressure changes.
Bone Basics
Source Institutions
This is an activity (on page 2 of the PDF under Bone Regrowth Activity) about the two main components of bone - collagen and minerals (like calcium) - and how they each contribute to its flexibility a
The Carbon Cycle: Carbon Tracker
Source Institutions
In this activity, learners play NOAA's Carbon Tracker game and discover ways to keep track of carbon dioxide and other greenhouse gases in the world.
Cleaning Air with Balloons
Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.
Gross Growth
Source Institutions
In this activity, learners grow germs collected from their hands and other objects. They cultivate the germs on a growth medium (such as slices of grapefruit or processed cheese) for a week.
How Did That Get There?: Water Pollution
Source Institutions
As a group, learners consider sources of water pollution to understand where pollution starts and where it ends up.
Headphone Helper
Source Institutions
In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.
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.
Toilet Model
Source Institutions
In this activity, PVC pipe, plastic water bottles and vinyl tubing are used to make a simple working toilet model. The model shows the role of a siphon in the flushing of a toilet.
Wind Power: Creating a Wind Generator
Source Institutions
This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.
Weather Forecasting
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Forecasting) is a full inquiry investigation into meteorology and forecasting.
Protect That BRAIN!: Mr. Egghead
Source Institutions
This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.
Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.
As the Rotor Turns: Wind Power and You
Source Institutions
In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from
Making Map Projections
Source Institutions
In this activity about cartography, learners work in teams to create two different map projections: a planar (or polar) and a cylindrical (or Mercator) projection.
Environmental Chemistry
Source Institutions
In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.
Making Mosaics
Source Institutions
In this archaeology meets art activity, learners make a mosaic and consider the ways in which art communicates.
Home Mycology Lab
Source Institutions
Agriculturalists have long considered mushroom growing a challenge, largely because you need a piece of benchtop equipment known as a laminar flow hood.
Fingerprint Identification
Source Institutions
In this activity (on page 2) about fingerprint analysis, learners use graphite from a pencil and scotch tape to capture their fingerprints.
Hot and Cold: Endothermic and Exothermic Reactions
Source Institutions
Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.
