Pupils interpret maps and graph data related to volcanic ash. Then they analyze the importance of wind speed and the dangers of the ash to both life, air temperature, and technology. 

Due to surface tension, dew — a liquid, is spherical in shape. Learners explore the properties of liquids in activity seven in this series of 36. Beginning with its basic properties such as boiling point and moving through to surface...

How is the wind up there? The class builds a topography model using materials available in the classroom, then place wind flags in different locations on the landscape. Using a fan as a wind source, pupils collect data about how wind...

There has been a huge solar energy spill! Let's go outside to play in it. This lesson includes multiple experiments showcasing solar and wind energies. Scholars build a solar heater and an anemometer before testing the results. The...

How important is momentum? Pupils investigate and apply the definition of momentum as they conduct analyses during a series of one-dimensional collisions. They infer the relative masses of two objects by carefully staging and predicting...

It is just magnetic. This resource presents the concept of Earth's and another planet's magnetic field and how spacecrafts detect them. Learners study a problem using magnetometers and participate in three experiments to come up with a...

In this space science activity, students read facts about the solar system. Students look at the diagram showing the position of the planets. Pluto is included as a planet here.

No need to be involved in a home economics or cooking courses to take advantage of this resource. Not only is there an explanation for how microwaves work but there are also tips for how to use the microwave, and cautions...

What is mu? Emerging scientists explore the coefficient of sliding friction, or mu, and apply its concepts as they complete activities in the interesting lesson. They measure the sliding friction between soles of their own athletic shoes...

New Horizons set forth on a mission to Pluto in 2006. Ten years later, the spacecraft is still on its way. Here, enthusiastic scholars predict what they will be like—likes, dislikes, hobbies, etc.—when New Horizons arrives at its...

Here is a concise article on short track speed skating which includes great illustrations of the short track (it shows how it differs from the long track), the "glide stride" used by skaters, and the skates worn by competitors. Watch a...
