Nature's Scuba Divers: How Beetles Breathe Underwater

As amazing as James Bond is, the surface tension of water does not allow him to walk on it! In this series of little lab activities, physical scientists play with the properties of water due to the hydrogen bonds and resulting polarity....

Keep the tension up in the classroom. The class first observes as the teacher creates a dome of water above a glass by adding paperclips into an already full glass. Classmates then work in pairs to see how many drops of water can fit...

Students study insects. They go on an outdoor insect outing and look for insects in a variety of places--in the air, under rocks, on leaves, in water, etc. They record information about the insects they find, including habitat, weather...

The need for a respiratory system in humans versus being reliant on gas exchange structures is demonstrated. There are many details about the advantages and disadvantages of each mechanism.  Students are able to learn about the...

Water beetles live underwater their entire lives, getting air from a bubble they carry with them. The video, part of an Insect playlist by Brain Scoop, explains how they breathe and why they are fascinating for evolutionary studies. It...

Water striders ... amazing aquatic acrobats or ferocious predators? Introduce life science scholars to these tough little insects using an engaging video. The narrator explains the strider's ability to walk on water and how it uses this...

Use science to help you walk on water! Young scientists explore the properties of liquids including cohesion, adhesion, and surface tension. They use graphs to compare different liquids and make predictions about their molecular attraction.

By viewing high-speed videos of raindrops hitting mosquitos, learn how insects are able to fly in the rain by calculating the impact forces of raindrops on flying mosquitoes.

Trying to plan a lesson on the respiratory system? Then take a deep breath, because this presentation has you covered. From the atmosphere through the lungs and blood to the body's cells, this presentation investigates the complex series...

Young learners compare the breathing patterns of different animals in this pinniped lesson. They examine the breathing pattern of California sea lions and northern elephant seals. Pupils collect, compare and analyze data concerning...
