Earth & Space Science: Holding it Together

Can a sidewalk increase the amount of pollution in local streams? Scholars learn the answer to this question though research and experimentation in the fifth unit in the six-part series. Pupils study runoff, impervious surfaces, and the...

A penny can be a much more valuable teaching tool that you might think. Whether you are teaching about chemical reactions, surface tension, the behavior of gases, or are just looking for engaging activities for early finishers, this...

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...

A drop of dew holds a sphere shape even when sitting on a seat thanks to the surface tension of water. Learners observe the phenomena of surface tension in water. Through demonstrations, hands-on activities, and discussions they explore...

Pop! Does your class know that bubbles help us understand our planet, molecular structure, and more? The video teaches how to create colorful vortices on a bubble using basic equipment. Then it explains other interesting ways scientists...

A helpful worksheet describes an interesting demonstration on the surface tension of water. Learners guess how many drops of water the heads side of a penny will hold. This resource does a great job of describing just how a penny can...

Students complete a variety of activities exploring the joys and science of bubbles. They listen to the book "Bubbles Bubbles" by Mercer Mayer, create a bubble picture using Kid Pix, and explore blowing bubbles. Students experiment...

Create jumbo bubbles and use them to teach about surface tension or interference, perfect for a physical science lesson on light or molecular attraction.

Mike and Kellie, a team of electrical engineers, demonstrate how to to design a contraption that accurately drops a marble onto a target. The materials needed and general instructions are provided on the website or via a downloadable...

Keith Johnson, a famous bubble artist, is highlighted in this time-warp video. Johnson explains some basic laws of nature as he blows and forms bubbles. Bubbles act like prisms and refract light, they want to be spheres, they are wet and...
