This tutorial by Bill Nye explains how to make a simple barometer using a jar and a balloon. The barometer is an old and accurate first look at predicting the weather by examining the pressure of the atmosphere. Students will discover how atmospheric pressure and surface gravity help meteorologists forecast the weather.
In this tutorial students will learn about static electricity. Students will also be able to explain what happens when neutral, positively charged, and/or negatively charged objects come into contact with one another.
This experiment from Bill Nye explains how to make a tornado in a bottle. Students will learn how gravity and air mass work together when creating a tornado contained within 2 bottles. Students will also discover how wind speed increases when colliding with warm air to create real world disasters that are known to be much more intense than hurricanes.
In this tutorial students will learn the importance of biological classification and how the process of biological classification changes over time. Students will also learn about current methods scientists use for classifying organisms and how to use a dichotomous key.
In this tutorial students will learn how Earth moves through space, how seasons are caused by tilt of Earth’s axis, and why different latitude zones have different average temperatures.
In this tutorial students will learn about water in the atmosphere. Students will learn about cloud types, cloud formation, humidity and dewpoint, and much more.
In this tutorial students will learn to distinguish between weather and climate. Students will also describe the main factors affecting regional climate and compare climate variations due to natural and human causes.
In this tutorial students will learn about the various biomes. This tutorial describes representative climate features of terrestrial and aquatic biomes as well as representative organisms of terrestrial and aquatic biomes.
In this tutorial students will learn about the four major types of air masses and how they create fronts that affect weather patterns.
In this tutorial students will investigate different types of weather phenomena (lightning, tornadoes, hurricanes, blizzards and floods). Students will also relate unequal heating of land and water surfaces to form large global wind systems and weather events such as tornados and thunderstorms
In this lesson, students will use the Demographic Transition Model (DTM), Rostowâ€™s Economic Development Theory and Wallensteinâ€™s Threeâ€“Tier World Systemâ€™s Theory to take a closer look at four countries in the world. Students will use the CIA World Fact book to research economic indicators, as well as Nation Master to research population pyramids and find correlations between them. Students will also compare the challenges and benefits of two countries that are at two different stages of the DTM.
This video helps students determine whether a given value is a solution to a given linear equation in one variable or linear inequality in one variable.
In this tutorial students will learn how a generator produces an electric current from the interaction of magnetic and electric field lines. Students will also investigate applications of magnetism and its relationship to the movement of electrical charge as it relates to electromagnets, simple motors, and permanent magnets.
In this tutorial students will learn about the difference between static and current electricity, explain how an object can gain or lose a charge, identify the charge (positive or negative) of a substance if given numbers of positive and negative particles, and define electric discharge and grounding.
In this tutorial students will learn about what makes a compound binary and ionic. Students will also learn how to write a molecular formula for a binary ionic compound when given the systematic name and demonstrate how to name a binary ionic compound that includes a transition metal.
