Though this is meant to be second in a two-part lesson plan, the two are not dependent on each other. Pupils play the roles of visible light rays, light or dark surfaces, and carbon dioxide molecules. They interact and react according to...

After brainstorming what they know about ocean acidification, youngsters place eggs in acid to determine the effects on calcium-containing organisms, and add carbon dioxide to solutions with sea shell material to discover the impact on pH. 

As a demonstration or as a hands-on activity, your class watches as the combination of vinegar and baking soda produce carbon dioxide gas. The intent of the lesson is to help youngsters understand that gases occupy space. It is included...

Respiratory systems are different in worms, fish, and human lungs, and each are explained by Paul Andersen with his fabulous SMART Board. How are these respiratory systems similar? Keeping breathing surfaces moist is essential in all...

In this episode of "Steve Spangler Science" videos, the gas produced by the sublimation of carbon dioxide dry ice creates a nice, fluffy cushion in a bowl of water. Since it is less dense than a soap bubble and cool enough to keep it...

Here is an engaging demonstration of density that you can do with your young physical scientists. Place different rough surfaced objects into carbonated liquid. The carbon dioxide bubbles collect on the surface of the objects and...

A rather simple, but impressive activity is displayed in this Steve Spangler Science video. Dry ice, solid carbon dioxide, is used to create gas-filled bubbles. You can perform this as a demonstration when teaching chemistry classes...

Create a cauldron of bubbling fun with this Halloween-themed demonstration idea. Using dry ice, Steve Spangler creates a crystal ball. If you compare the sublimation of dry ice to the melting of water ice, it is a wonderful way to...

This quick clip shows the chemical gas exchanges that occur during respiration. Despite the robotic voice, this is an accurate and quick display of part of the respiratory process.

Carbon is a key element in life on Earth. Where can it be found? Hear all about carbon's whereabouts and how it is used. Climate change is brought up along with human responsibility. This clip is great for a junior high or high school...

Intersperse your viewing of this video with questions that are shown on the screen. Keep your learners engaged by having them take notes and answer the questions. Parts of the respiratory system are shown with pictures and animation...

Carbon is all around us, as shown in this cartoon animation. The carbon cycle is portrayed simply and accurately with fun cartoon plants and animals. Use this video in an elementary or junior high class to facilitate your learners'...

Young scientists discover that air is a mixture of different gases - mainly nitrogen and oxygen. The properties of some of the other gases found in oxygen are listed in a table, then learners must decide which one of those gases is...

Here is a instructional activity that outlines the main causes of the production of greehnouse gases. There are seven gases listed, and learners must research and write down the main way in which humans produce that gas. This is an...

Get your middle schoolers experimenting with dry ice. In the first activity, they place a piece in water and then use phenol red to identify its pH. In the second, they place a piece in a limewater solution and watch as the combination...

A series of lab activities helps to fill ecology classes in on the production of biofuels. They perform chromatography and fermentation experiments, writing up their own lab reports for each activity. The lesson concludes with a...

Interested Earth enthusiasts are introduced to ice ages. The 26,000-year cycle is charted and the eras named. Several slides are dedicated to the carbon cycle and how it contributes to the changes. The reasons for the cooling of the...

Hands on science is the way to go! Learners conduct a lab experiment to help them explain how plants make food through photosynthesis. They test for the presence of starch in leaves using iodine solution and identify the basic things...

When you need a review worksheet for your AP biologists on water and nutrient transport in plants, this one is for you! From the simple stuctures involved to the complex mechanisms that make it happen, the details of transport are...

Five questions are presented and answered as a means of delivering information on the respiratory system. Using red and blue game chips, physiology learners model the movement of blood through the lungs. Groups of learners time how long...

Emerging ecologists need a full understanding of life, from the inner workings of a cell to the complex relationships among organisms. This examination is meant to assess high schoolers after an entire year course on the living...
