THE TRICKLE DOWN EFFECT

First in a two-part lesson on the greenhouse effect, this lesson involves a classroom demonstration of the phenomenon, and a lab group experiment with color and absorption. Although there are easier ways to demonstrate the greenhouse...

This well-organized lab activity introduces earth science pupils to the greenhouse effect. They will set up two experiments to monitor temperatures in an open jar, a closed jar, and a closed jar containing water. Ideally, you would have...

Dive into the power of the sun with a two-part lesson. Budding scientists model the greenhouse effect in a hands-on activity, and then participate in a skit that explores the earth's energy balances and what really occurs in the...

How do greenhouse gases affect the climate on Earth?  Pupils explore the concept by first building their own apparatuses to model the greenhouse effect. Then, they record data to measure temperature change and determine...

Here comes the sound. After watching a couple videos demonstrating and explaining the Doppler Effect, learners develop their own understanding of the phenomenon. Scholars draw a sound wave and observe how the perception of the wave...

A greenhouse provides additional warmth and protection to the plants inside, but what if the greenhouse gets too hot? Pupils discuss and experiment with the difference between natural and anthropogenic greenhouse effect. They measure the...

Pupils compare the temperature change in a closed and open box as a demonstration of the greenhouse effect. 

What a terrific demonstration! Watch Steve Spangler stick a wooden skewer through a balloon. He demonstrates the effect of stretching polymers with this amazing activity. Use it during your chemistry class when studying molecules.

Now this is a very good demonstration of the Doppler Effect and how it works. A police car with its siren blazing is filmed as it travels closer and then farther away. The effect is explained through text and an illustration. Good video.

Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...
