A curious pre-school child asks questions to a big kid about how weather works. Every answer is enlightening yet leads to another question. The little child learns that wind is air that moves, that may be gentle or strong and even...

An exothermic reaction gives off energy to the surroundings; like a fire giving off heat. An endothermic reaction takes in energy from the surroundings; like a snowman melting. Exothermic reactions transfer energy to the surroundings,...

This video, explains how to compare positive and negative numbers using a number line. They use real-world examples such as submarine depth and thermometer readings to illustrate the concept. By understanding the relationship between...

Weather forecasting requires observation. Beyond the things we can see, hear and sense, meteorologists need detailed data to observe distant weather, whether that is distant along the ground, or distant up into the sky. Weather...

In this video, students learn how to use positive and negative numbers by understanding temperature. The lesson covers the concept of a vertical number line, the difference between Celsius and Fahrenheit, and how to interpret different...

A little girl and her grandfather spend a summer afternoon sitting by a pond. The conversation changes from how warm the summer day is to how the pond gets cold and freezes in the winter. The grandfather helps the girl understand how the...

Upon viewing the Heat and Energy video series, students will be able to do the following: State the difference between kinetic and potential energy. Name and describe six different forms of energy: thermal, chemical, mechanical,...

When food is prepared or held at improper temperatures, harmful bacteria can grow inside of the food making it unsafe to eat. Using an accurate food thermometer to monitor food temperatures can help ensure the safety of your food. It...

This video illustrates the many everyday ways we measure things, and the importance of measurement in science. Concepts and terminology: length, liquid, mass, scale, temperature, and time.

Upon viewing the Measuring video series, students will be able to do the following: Generally explain that the process of measuring involves making observations of things using tools. Understand that measurements often involve the use...

Air and moisture in different quantities comprise our atmosphere. The sun is the energy source that causes temperature change, wind, clouds, rain, dew, blue skies and rainbows. See how to build an instrument called a "sling psychrometer"...
