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.
Teen Moon: Moon Ooze
Source Institutions
In this activity, learners model how the Moon's volcanic period reshaped its earlier features.
Balloon Nanotubes Tabletop
Source Institutions
This activity introduces learners to the structure and properties of carbon nanotubes.
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.
Jump to Jupiter
Source Institutions
In this activity, learners help create and then navigate an outdoor course of the traditional "planets" (including dwarf planet Pluto), which are represented by small common objects.
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.
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.
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.
Human Traits
Source Institutions
In this activity, learners investigate variations in human traits. This allows learners' natural curiosity about their identity to draw them into the study of heredity.
Water, Water Everywhere
Source Institutions
In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
Size, Mass, Area, and Volume
Source Institutions
In this activity (page 23 of PDF), learners conduct an experiment to determine how the size and mass of a projectile affects the area and the volume of an impact crater.
Cryptographic Protocols: The Peruvian Coin Flip
Source Institutions
This activity about cryptographic techniques illustrates how to accomplish a simple, but nevertheless seemingly impossible task—making a fair, random choice by flipping a coin between two people who d
Look Mom, No Wings!
Source Institutions
In this activity about flight, learners explore how high they can jump. Learners dip their finger in ink or dirt, then jump as high as they can and mark paper attached to the wall.
Exploring Materials: Graphene
Source Institutions
In this activity, learners investigate the properties of graphene and graphite.
Two-String Yo-Yo
Source Institutions
Learners build a yo-yo using a piece of wood, PVC pipe, and string. In doing so, learners explore the force of gravity and angular momentum.
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.
Invisible Investigations
Source Institutions
Using indirect observational methods, learners distinguish between charged and uncharged objects.
