Handwriting Analysis
Source Institutions
In this forensics activity, students will explore the methods that investigators use to confirm the authenticity of handwriting.
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.
Photolithography
Source Institutions
In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.
Battling for Oxygen
Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.
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.
Teen Moon: Moon Ooze
Source Institutions
In this activity, learners model how the Moon's volcanic period reshaped its earlier features.
Extra Bounce
Source Institutions
In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.
Shrinking Coin
Source Institutions
In this demonstration, learners attempt to get a large coin through a small hole, the size of a smaller coin.
Test the Finger Wrinkle Hypothesis
Source Institutions
Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?
Levers at Play
Source Institutions
In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).
On the Fringe (formerly Bridge Light)
Source Institutions
In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.
Weathering and Erosion
Source Institutions
In this multi-station lab, learners conduct a series of experiments to explore the processes and effects of weathering and erosion.
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.
Moving and Working in Space
Source Institutions
In this activity, groups of four learners must complete a set of four manual tasks. The restrictions are that they must complete the tasks in a limited time while wearing garden or rubber gloves.
Litter Critters
Source Institutions
In this outdoor activity, learners use a "litter-critter" wheel to help them identify different animals they find living in a natural litter habitat.
Capturing Carbon Dioxide
Source Institutions
In this activity, learners investigate carbon sequestration by creating a carbonated beverage out of apple juice and dry ice.
Neato-Magneto Planets
Source Institutions
In this activity, teams of learners study magnetic fields at four separate stations: examining magnetic fields generated by everyday items, mapping out a magnetic field using a compass, creating model
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.
Up, Up, and Away
Source Institutions
In this math lesson, learners explore the real world meaning of slope. Learners conduct a balloon experiment in which they measure the circumference and flight time of deflating balloons.
2-Liter Landfill
Source Institutions
In this activity, learners gain a better understanding of how household/school waste breaks down in a landfill. Learners collect trash and then create miniature landfills in 2-liter bottles.
