The environmental consequences of tiny quantities can be huge. In this activity we use dye and water to show how big a tiny change can be. Students sequentially add drops of food coloring to one liter of water to assess the change caused by a trace component. The changes can be described qualitatively, or, quantified with photographs or a light meter.
For International Women’s Day, Alexandra Moore, one of PRI’s women climate scientists, has created short video features on some of the activities that she engages in across a typical day. This toolkit includes these videos along with student activities that match the theme of each film.
Using materials like iodine, blackberry juice, and a few specialized components, students will create a working solar cell that mimics the process of photosynthesis.
Students measure the flux of carbon dioxide from soil to the atmosphere using a lab CO2 probe and home-made flux chambers. The experiment can be designed to allow students to manipulate the experimental conditions, and explore the relationship between temperature and respiration, pointing to an important consequence of global climate change.
This activity involves building a tiny, wind-powered elevator: a small cup lifted by a pinwheel. You could use the elevator to lift things from the ground floor to the second floor of a house you make from shoe boxes.
Students work together to create a rope timeline that illustrates time scales of thousands of years compared with human lifetimes.
Students use art to express their vision of what a better climate future could look like in their community, and how we could achieve this.
Students build small paper houses and design and build structures such as gutters and rain gardens to divert and capture rainwater. They then test their designs with simulated rain.
Students build a simple wind dial (anemometer) and explore how pine cones can tell us about humidity in the air.
Students learn through play in this activity where they devise, create, and test ideas for protecting a garden from heavy rains.
Students use basic thermometers to measure air temperatures under different conditions, draw conclusions about why air temperatures differ in these conditions, and apply what they’ve learned to strategies for staying cool during extreme heat events.
In this activity we calculate the coefficient of thermal expansion for tap water. Students will heat water in a long-necked glass bottle to explore the relationship between temperature and volume of water. Quantifying the initial volume, change in volume, and the initial and final temperatures allows students to calculate the coefficient of thermal expansion.
Students measure a soil temperature profile to explore the effect of energy from the Sun on the shallow subsurface environment. Multiple temperature profiles allow students to analyze the daily change in energy that diffuses into the subsurface, and its differential impact near the surface and at depth.
