Focus on inquiry-based learning in your science class with a series of activities designed for middle schoolers. A helpful packet samples four different texts, which include activities about predator-prey relationships, Earth's axis and...

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to learners their different roles in the activity, the teacher reads aloud a...

Learning about waves can have its ups and downs, but a demo-packed tool kit has the class "standing" for more! Learners gain experience with several different wave types, organizing observations and data, and wave terminology. The...

The three types of rock aren't classic, punk, and hard. The chapter covers everything scholars need to know about rocks. Pupils compare rocks, learn about their formation, see how rocks change, and follow every step of the rock cycle....

Mr. Khan uses a metaphor of a car to help explain the change in direction of waves as they hit a boundary between two mediums. He then goes on to explain the relationship between the structure and density of the earth and the behavior of...

Sal continues this short series on specific heat and vaporization. The situation he poses uses 500 grams of liquid water at 60 degrees Celsius, with the goal of getting the water to 0 degrees Celsius. The ice he adds to the water comes...

Sal goes back to a look at the Adiabatic process in this chemistry video. He sets up a Carnot Cycle that occurs within an adiabatic process; meaning there is no transfer of heat. From that problem, Sal constructs Volume Ratios which is a...

In this video about the reproductive system, the narrator discusses the importance of sex — to reproduce and pass on genetic material — and reminds viewers of the differences between the gametes. He then explains the reproductive parts...

The theories behind Quasistatic and Reversible Processes are offered in this chemistry video. Sal sets up a hypothetical situation in which gases are escaping from a piston in a car's engine. He uses this scenario to illustrate exactly...

View and explore different types of ecosystems found in our environment. Learners will study, discuss and view examples of 7 vocabulary words associated with ecosystems. They will also draw examples of different species found in...
