Learners see that a carrot slice sinks in fresh water and floats in saltwater. Considering the placement of the carrot slice in water and saltwater, learners infer that the density of salt water must be greater than the density of fresh water. As a challenge, learners adjust the density of the saltwater until they get the carrot slice to hover somewhere in the middle of the cup. Less

Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float. The density of the clay used in this activity does not change, but the volume of the object made from the clay increases. This increase in volume decreases the overall density of the object, making it float. Less

In this multi-part activity learners examine non-point water pollution. Learners discover ways they may be contributing to this type of pollution and brainstorm ways to change their behavior to be more environmentally responsible. Designed as a family exploration, the activity includes watching two short educational films about the Hudson River, discussing hypothetical pollution scenarios, auditing your own stock of pollutants under the bathroom sink, brainstorming alternative products, and sharing your results. The activity could easily be adapted to non-family educational groups and could be done in one chunk, or over the course of several sessions. Less

To increase students' awareness of possible invisible pollutants in drinking water sources, students perform an exciting lab requiring them to think about how solutions and mixtures exist even in unsuspecting places such as ink. They use alcohol and chromatography paper to separate the components of black and colored marker ink. Students witness first-hand how components of a solution can be separated, even when those individual components are not visible in solution. Less

This lesson explores the importance of protecting sources of clean drinking water. Through a narrated slide show, Peace Corps volunteer Lauren Fry shares her story about building a springbox to protect a groundwater supply in Cameroon. Students will synthesize information from the slide show, examine additional photographs depicting water access issues in Africa, and discuss the connection between clean water and quality of life. After discussing Lauren's story, choose from the suggested math and science activities to extend students' learning. Less

In this activity on page 7 of the PDF, learners make their own water treatment systems for cleaning water. Learners construct two filters to test: one with sand and one with sand and charcoal. Learners compare how well the sand and sand + charcoal filters clean water that is "dirtied" with food coloring, dirt, and grass. This activity also features a list of ten ways you can conserve water. Safety notes: Adult supervision is needed for this activity. Do not drink any of the water samples in this activity. Make sure to follow the safety tips listed on page 3 of the PDF, as well as those listed in the procedure for the activity. Less

This Climate Change Impacts Collection provides the teacher and their students the opportunity to explore some of the environmental changes already observed, from the Arctic to tropical regions. Data sources provide historic precipitation and temperature records, allowing students to compare changes in their own local area to others. Lessons included, provide opportunities for place-based instruction related to climate change, others provided a more global perspective. The background resources provided in this collection tend to be for the teacher and/or the advanced student. Less
