Students will investigate how the eye detects color, and how fatigue in the cones can cause the perceived color of an object to change.
Students will investigate the phenemenon of sunlight traveling through the atmosphere. Blue light scatters more than the other colors, leaving a dominant yellow-orange hue to the transmitted light. The scattered light makes the sky blue; the transmitted light makes the sunset reddish orange.
In this activity students test a variety of liquids and solutions to see which conduct electricity. Note: This is designed for use in a science museum or education center and may need to be modified for classroom use.
This activity demonstrates chemical reactions as evidenced by color changes. Students will systematically evaluate all possible combinations of solutions and draw inference from their observations to determine which combinations experience a chemical reaction.
In this lesson students will understand how charges attract and repel and can move between objects by charging a variety of objects and making observations about their interactions.
This video provides information about the causes and effects of Earth's changing climate, specifically focusing on wildlife populations and the impact global warming has on habitats.
Students will be introduced to the rock cycle by scraping crayons to create small particles and then press and/or heat the particles to simulate rock formation processes.
This set of activities uses hands-on activities, group discussions, demonstrations, and science journaling to aid student understanding of erosion processes.
Students will use marbles and weights to discover some basics about gravity. The set-up for the activity includes stretching fabric over two buckets. Students will then place marbles of different sizes and weights on top of the fabric and make observations.

Students will investigate the "hardness" characteristics of minerals. They will scratch the samples with fingernails, pennies, and nails and then classify the mineral sample according to the Mohs Hardness Scale.
This interactive resource presents information about six single-celled organisms commonly found in pond water. The user selects an organism to view through a "virtual" microscope. As the user views each organism, informational text appears. Amoeba, vorticella, euglena, paramecium, spirogyra, volvox, are included in this collection.
Students will investigate relative size and distance by creating a basic model of our solar system.
Resources include active webpages with text about major topics associated with climate change issues and a music video for the song "Take Aim at Climate Change." The lyrics in the rap music video provide background content information about the causes and effects of global climate change. A supplemental page links footnoted information in the lyrics to additional web resources.
