Learners will use an inexpensive, simple spectrophotometer to test how light at different visible wavelengths (blue, green, red) is transmitted, or absorbed, through four different colored water samples. Clear water is used as the “control,”... (View More)

In this activity, students face an engineering challenge based on real-world applications. They are tasked with developing a tool they can use to measure the amount of rain that falls each day. Students will find out why freshwater is important,... (View More)

In this activity, participants learn about the hydrosphere by making observations and taking measurements. They will go outside and use scientific equipment to investigate temperature, pH and transparency of a body of water. They will use this... (View More)

In this demonstration activity, students make structural models of gas molecules using pipe cleaners and polystyrene balls and test their molecules for their resonant frequency. Students shake the models, count vibrations, and compare the resonance... (View More)

In this experiment, students create a "lava lamp" - a beaker on a hotplate, and investigate buoyancy, convection and other fluid and thermodynamic properties using ink, water, vegetable oil and Alka-Seltzer tablets. The activity is from PUMAS -... (View More)

In this activity, students devise ways to demonstrate that energy can change from one form to another in accord with the law of conservation of energy. Small appliances, toys, marbles, vinegar and baking soda, simple electrical supplies available... (View More)

This is a hands-on lab activity about the water cycle, specifically evaporation and condensation. Using materials such as clay, ice and a lamp, learners will observe the relationship between temperature and condensation and temperature and... (View More)

Students are introduced to classification through progressive activities. Initially, the teacher models the task by classifying buttons. Students then devise a classification scheme for paper clips. Subsequent activities use objects brought from... (View More)
