This lesson plan engages students in a real-life exploration of climate change as it is affected by greenhouse emissions from vehicles. The aim of this activity is for students to realize the impact of vehicle use in their family and to give students the opportunity to brainstorm viable alternatives to this use.

In this physics activity, challenge learners to lift a book with just air using a plastic bag and a straw. This activity demonstrates compressed air and forces.

In this engineering activity, young learners investigate multi-level buildings. Learners observe buildings in their neighborhood and then, using simple household materials, create their own multi-level models. This activity (page 4 of the PDF) is part of the Curious George "Under Construction" lesson plan, which includes several activities that explore building engineering. Activities are connected to fiction and non-fiction books and include family extension projects.

In this "Sid the Science Kid" activity, learners make applesauce to explore irreversible change. Learners compare and contrast apples that have been changed by heat with apples that haven't been changed. This activity includes a "Sid the Science Kid" video showing how to conduct the investigation. Safety note: adult supervision required.

In this activity, learners investigate whether more people are squares or rectangles. People with similarly sized heights and arm spans are classified as squares. People with different sized heights and arm spans are known as rectangles. Learners measure and analyze the body shapes of family and friends.

In this activity, learners surprise their eyes with an optical illusion involving arrows made out of pipe cleaners. Even thought the pipe cleaners are the same length, learners will discover that one appears shorter than the other.

In this physics activity, challenge learners to make and race a balloon-powered car. Learners construct the body out of a paper cup, wheels out of wooden spools. and fuel tank out of a balloon. Demonstrate motion, forces, and kinetic and potential energy.

In this activity, learners make a helium balloon "flink"--neither float away nor sink to the ground. Use this activity to introduce physics concepts related to gravity, density, and weight.

In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge. Learners then determine the algebraic equation that best represents that pattern modeled by these three variables (thickness, length, and supported weight).

In this Cyberchase interactive simulation students help the Cybersquad gather bugs to create a bar graph by sorting the bugs into the correct columns by color. Once three graphs have been created they are prompted to answer a question comparing the graphs, all of which have different scales. The simulation includes instructions and hints.

In this physics activity, challenge learners to make a race-car out of a coffee can and rubber band. Demonstrate motion, forces, kinetic and potential energy and friction.

In this online math game from Cyberchase, learners are challenged to fill containers with water using three different sized pots. Learners select the combination of pots that will fill the containers with the fewest number of pours, without spilling over. This online activity could be used as an introduction to a hands-on measuring activity, or as a cleaner alternative to a hands-on measuring activity.

In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt. Learners can experiment using other materials like sugar and sand.

As a segment in PBS's Coping with Climate Change series, Hari Sreenivasan reports on the actions the city of Chicago is taking to mitigate climate change in an urban landscape.

In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion. The online version of this activity is set up so that learners solve a mystery.

This video and accompanying essay examine ways to reduce the environmental impact of burning coal. Two technologies are discussed: turning solid coal into a clean-burning fuel gas (syngas), and capture and storage of CO2.

In this "Sid the Science Kid" activity, learners get their hands dirty by playing in a container of soil. Then they compare the effectiveness of cleaning their hands with just a paper towel vs. soap and water. Use this activity to introduce the importance of hand-washing and cleanliness. This activity includes a "Sid the Science Kid" video showing how to conduct the investigation.

This PBS video focuses on sea level rise in Norfolk, Virginia and how the residents are managing the logistical, financial and political implications. Science journalists who have been studying Norfolk's rising sea level problems are interviewed, as well as local residents who are being impacted.

This video explains how scientists construct computer-generated climate models to forecast weather, understand climate, and project climate change. It discusses how different types of climate models can be used and how scientists use computers to build these models.

In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.
