Chemistry

Experience the nature of scientific inquiry and scientific problem solving using this unique color change challenge lab! Students must discover a sequence of chemical changes-using four unknown colorless solutions-that will result in a series of spec...

Teach your students basic problem-solving skills! Challenge them to develop and test a hypothesis to determine the ideal environmental conditions for specially encapsulated sponge animals to emerge from their “cocoons”. In the process, they learn the...

Challenge your students to solve the puzzle of the unknown solutions. In this guided-inquiry activity, students brainstorm how to match three colorless mystery solutions with the same solutions a partner has. There is one catch—once a course of actio...

Introduce students to the scientific method of problem solving and get them to start thinking “scientifically.” By manipulating a black box and hearing and feeling how the steel ball rolls around inside the unopened box, students begin to make observ...

Students mix two solids and a liquid in a closed container and observe a dramatic series of changes-temperature changes, color changes, and changes in state. What interactions are responsible for each observation? Are the changes independent of one a...

The scientific method is a logical process of inquiry and investigation. Students gather observations about the problem, develop a hypothesis, design and implement a controlled experiment, record constants and independent and dependent variables, gra...
