Differing Densities: Fresh and Salt Water
Source Institutions
In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.
Wild or Domestic Animal Game
Source Institutions
In this quick activity (page 2 of PDF), learners will play a game using their observation and listening skills, interpreting clues from each other to deduce their secret animal identity.
Population Game
Source Institutions
In this outdoor game, learners simulate a herd of deer trying to survive in an area called the "home range." Learners explore the concept of "carrying capacity"—what size population of an organism can
Burning Issues
Source Institutions
Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.
Observing Different Microbes
Source Institutions
In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.
Oil Spill Solutions
Source Institutions
In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.
Caring Together: Activity Stations
Source Institutions
In this Bob the Builder(TM)-themed activity, learners explore the 3Rs (Reduce, Reuse, Recycle) by rotating through several activity stations.
What is in the Water?
Source Institutions
In this activity, learners use open inquiry to learn about the process of science as well as gain experience regarding the Law of Conservation of Mass, dissolution, and density.
Powdery Mildew Fungi: Classification and Ecology
Source Institutions
In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery
Fossil Age Estimation Model
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa
Wind Works!
Source Institutions
Learners will build and experiment with their own windmills made from simple household materials.
What Does Life Need to Live?
Source Institutions
In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).
Plastics the Second Time Around
Source Institutions
In this activity, learners test and compare the physical properties of thermoplastic polymers. Learners compare different plastics based on their color, degree of transparency, texture, and density.
The Carbon Cycle: How It Works
Source Institutions
In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another
Design a Park
Source Institutions
In this activity, learners are invited to imagine the park of their dreams!
Rain Machine (Solar Still)
Source Institutions
In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.
Floodplain Modeling
In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.
Engineer A Bird Feeder
Source Institutions
In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.
Geometry and Spatial Relations: Tessellations WOW!
Source Institutions
In this math lesson, learners explore tessellations through literature, music, writing, and art activities.
Conductivity: Salty Water
Source Institutions
Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity?
