OBIS Oil Spill
Source Institutions
In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.
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.
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?
Leaf it to Me
Source Institutions
In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.
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.
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.
Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.
Moisture Makers
Source Institutions
In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.
Disappearing Water
Source Institutions
In this outdoor water activity, learners explore evaporation by painting with water and tracing puddles. Learners will discover that wet things become dry as the water evaporates.
The Rain Man
Source Institutions
In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.
Making Rivers
Source Institutions
In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.
Great Steamboat Race
Source Institutions
In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.
Moving On Up: Capillary Action 1
Source Institutions
Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.
What-a-cycle
Source Institutions
In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.
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.
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
Super Soaker
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
Use Clues to Solve an Ice Mystery
Source Institutions
Learners explore the variables that affect the properties of ice and the places where different types of ice are found.
Moving On Up: Capillary Action II
Source Institutions
Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms.
Heat Capacity: Can't Take the Heat?
Source Institutions
Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.
