Sugar crystal growth is observed as an example of physical change and cabbage juice pH indicator is used to demonstrate chemical change. The crystal growth is tracked over five days. The cabbage juice experiment is involved and can also...

Pupils use common and unusual objects to make observations of details, design, and functionality. They describe and draw each object while working in small groups. The differences between observation and perception is covered as part of...

Up, up, and away! Take your classes on a physics adventure. Learners explore the concepts important for flight. They experiment with the Bernoulli Principle while learning the forces that act on airplanes in flight.

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

Many people think of bugs as annoying pests to be squashed, but most insects and spiders are beneficial, eating the actual pests or pollinating plants. After reviewing some of the common bugs in your area (they may differ from those...
