In this activity, students will learn about phosphorescence and how certain materials can absorb and store energy from a light source. Students will use critical thinking skills to hypothesize which type of light -- incandescent, ultraviolet, infrared or fluorescent -- will produce the brightest glow from a glow-in-the-dark star. Students will perform an experiment using cameras to observe the intensity of the resulting glow from each type of light source.
In this activity, to learn about the biological needs of mosses, students will grow and maintain their own moss terrarium. Through daily maintenance and observation, students will identify those factors necessary for the successful cultivation of moss.
In this activity, students will use household materials to investigate and explore how the release of carbon dioxide gas from a chemical reaction can cause a small-scale explosion. Students then will experiment with variables to determine which factors launch a film canister the highest.
In this activity, students will use a stream table to investigate river formations in two different landscape scenarios. Students will compare and contrast how the formation of the river differs if the topography of the land is changed from a flat plain to a terrain with hills and valleys.
In this activity, students will compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light. Students will also compare these forms of luminescence to bioluminescence.
In this activity, students will review and discuss weathering, erosion and mass wasting, to gain a stronger understanding of how Hickory Run’s Boulder Field was formed after the Laurentide Continental Glacier receded. Using edible materials, students will model and demonstrate the geological processes that formed this unique feature.
