Hand Washing Experiment

Sometimes, despite the best laid plans, the unexpected will occur. Learners witness this firsthand as they carefully design an experiment to determine the time needed for ice to melt in salt water or pure water. They uncover facts not...

First in a two-part lesson on the greenhouse effect, this lesson involves a classroom demonstration of the phenomenon, and a lab group experiment with color and absorption. Although there are easier ways to demonstrate the greenhouse...

Not all liquids are the same. Investigate the viscosity of different fluids with a series of activities designed for eighth grade science. As learners move through learning centers with different experiment setups, they determine...

Teach young environmentalists to protect their planet's resources with a set of interactive experiments. Kindergartners and other youngsters learn about watersheds and the water cycle, while older elementary learners focus on fertilizer...

Carbon dioxide makes up an incredibly small percentage of our atmosphere, so why is it so important? The video explains that humans passed the 400 parts per million mark in 2013. It highlights the causes of the increase and our...

Students explore the concepts that enable them to design and conduct sound scientific experiments. They critique a faulty experiment and become familiar with some of the criteria of a good experiment. They conduct their own experiment.

Not all animals respond to pain the same way. Thanks to the structure of the nervous systems of different living organisms, vertebrates and invertebrates experience nociception—the sensory nervous system's response to pain.  

Get hands-on in your physical science class by having learners conduct electricity with their own hands! By placing one hand on each of two different metals, a current can be generated and measured on a microammeter. Make an experiement...

Do not let the class just sit and rot. Pupils learn how decomposition and nutrient recycling is important to an ecosystem. Groups design an experiment to determine how environmental conditions affect decomposition. They develop a poster...
