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,...

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...

Explore the effects of gravity using this demonstration on surface tension. Learners fill a glass with water, put a handkerchief over the top creating a seal, and then turn the glass over without losing a drop. This is a terrific way to...

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.

Making your own bubble solution is fun, but sometimes the bubbles don't seem to work as well as the solutions you buy in the store. In this experiment you can test if adding corn syrup or glycerin to your bubble solution will make it...

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...
