Shoebox Dinosaur Dig Site
Source Institutions
In this activity, (on page 6 of the PDF under SciGirls Activity: Dinosaurs) learners participate in a hands-on fossil excavation.
Plenty on the Plains
Source Institutions
In this activity, learners compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent
Regolith Formation
Source Institutions
In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.
Shadow Play
Source Institutions
In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.
Storm Water Runoff Pollution
Source Institutions
This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.
Clippy Island: An Investigation into Natural Selection
Source Institutions
In this activity, leaners will observe the process of natural selection on a population of birds called 'Springbeaks' over four seasons of breeding on an isolated environment called 'Clippy Island.' L
What's for Dinner?
Source Institutions
In this activity (page 5 of the PDF), learners will create a food web and explore food sources for different organisms. They will identify relationships between organisms in an ecosystem.
Ocean in a Bottle
Source Institutions
In this activity, learners consider how oil spills behave in the ocean and what impact they have on marine wildlife.
Can Nutrients in Water Cause Harm?
Source Institutions
In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.
Hold It
Source Institutions
In this outdoor activity/field trip, learners investigate the special shapes, holding structures and holding behaviors that real organisms use in streams, rivers, creeks or coast intertidal zones to a
Survival of the Fittest: Variations in the Clam Species Clamys sweetus
Source Institutions
This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi
Survival of the Fittest: Battling Beetles
Source Institutions
This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.
Cave in a Cup
Source Institutions
In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then
Sticklers
Source Institutions
In this outdoor simulation game, learners search for pretend animals called "sticklers" to determine and map where they live (habitat) and how spread out they are in that area (distribution).
Evolution as Reproduction with Variability
Source Institutions
In this online activity, learners discover how random variation influences biological evolution.
Solar Cell Simulation
Source Institutions
In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.
Stream Table
Source Institutions
In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.
Trees: Recorders of Climate Change
Source Institutions
In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho
Zero-Energy Housing
In this activity, learners investigate passive solar building design with a focus solely on heating.
Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.
