How Sticky Is Your Tape?

Someone stole a diamond-making machine. Who done it? Scholars use forensic science at six different stations to determine the culprit. They analyze fingerprints, use their senses, and complete chemistry experiments to determine the...

Students test the adhesive strength of different tapes. In this adhesive lesson, students conduct an experiment to test the shear strength of the adhesives, take measurements, record data, and draw conclusions to explain each product's...

Learners test the stickiness of natural substances. In this adhesion as a property of matter lesson, students build a tool to test the adhesion of natural "glues" such as honey, peanut butter, flour and water paste, and jelly. Learners...

Turn your classroom into a live demonstration of how the earth and sun interact to create the four seasons. Using a globe, a light source, and a series of constellation cards, super scientists discover how the motion of these...

More than 100 cities around the world have shifted from fossil fuels to renewable energy sources. Scholars investigate a city wanting to make this switch, but needs help determining how to make the shift. Groups consider all options,...

Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science activity introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a chemistry...

A video and laboratory investigation are highlights to this lesson on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon dioxide...

Students engage in a lesson that is concerned with the concept of water chemistry. They conduct research using a variety of resources. Students also consider an experiment to observe how water has the abiility to exist as three different...

What do a dead fish, conservation, and paint have in common? The answer is a great instructional activity about fish anatomy, fun print making techniques, and unsustainable fishing practices. The class will start by making fish prints...

Learners observe exothermic reactions in the lab using plaster. For this chemistry lesson, students collect data from their experimental set up every five minutes. They explain the different stages in the hardening of plaster.
