I Am/Who Has: A Litter Matching Game
Source Institutions
In this game, learners match descriptions of marine debris (shoes, batteries, paper towels, etc.) to images of these items.

A Hole in the Ground
Source Institutions
Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.

Measuring the Wind
Source Institutions
In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

Melting Ice
Source Institutions
In this activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.

Tiny Geyser Models
Source Institutions
In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.
Tsunami: Waves of Destruction
Source Institutions
In this activity, learners use tsunami time travel maps to predict how long it will take a tsunami to reach the shore.

Sea Level: On The Rise
Source Institutions
Learners will understand the relationship between climate change and sea-level rise.

The Best Dam Simulation Ever
Source Institutions
This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

Introduction to Ocean Zones
Source Institutions
In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

Globe at Night
Source Institutions
In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

Build a Coral Polyp
Source Institutions
In this activity, learners build one or more edible coral polyps and place them together to form a colony.

Wonderful Weather
Source Institutions
In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

Plant Piping
Source Institutions
Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

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

Who Dirtied The Water?
Source Institutions
In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).

Go with the Flow
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

Modeling Tidal Action
Source Institutions
In this activity (Lesson 1), learners work in groups to create tide simulations.

¡Terrario!
Source Institutions
En esta actividad, los aprendices harán un terrario usando materiales simples.
Fish Eyes: More than Meets the Eye
Source Institutions
In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

Going Green
Source Institutions
In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.
