Science Friday
Capturing Carbon Dioxide
Why don't we just capture carbon dioxide in the air and store it somewhere else? A hands-on lesson allows scholars to explore a complex concept. First, they will create a carbonated beverage, and then they will determine if liquid...
NASA
Making Oxygen and Carbon Dioxide
Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for confirmation....
America's Blood Centers
My Blood, Your Blood
Dracula isn't the only one who needs blood to survive. The eight-part unit includes seven lessons, five demonstrations, seven labs, and a project to organize a blood drive. Class members learn about the parts of blood, the form and...
Safe Routes to School
Pollution & Evolution
Bring together a study of two major scientific topics with a lesson on the relationship between pollution and evolution. With the help of a PowerPoint presentation, hands-on activity. and class demonstration young scientists learn how...
Carnegie Mellon University
Ocean Acidification
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.
Baylor College
Gases Matter
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...
Curated OER
Name That Gas!
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...
Curated OER
Evidence of Photosynthesis
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...

AP: Chapter 36: Transport in Plants
When you need a review instructional activity 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...
Curated OER
Greenhouse Gases
Although the worksheet for the lab activity is not included, this is an activating activity for your class to do when learning about the greenhouse effect. They lay three thermometers underneath a lamp: one out in the open, one under a...
Curated OER
Circulatory and Respiratory Systems Unit - Biology Teaching Thesis
Students Explain how an increased level of activity translates to cells needing more oxygen and how the lungs supply this oxygen by entering the blood stream. They also can explain that the heart is responsible for moving both oxygenated...

Changing Planet: Ocean Acidification - the Chemistry is Less than Basic!
A video and laboratory investigation are highlights to this lesson on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon dioxide...
Curated OER
Carbon Dioxide - Sources and Sinks
Where does all of the carbon dioxide come from that is supposedly leading to climate change? Earth science pupils test animal, plant, and fossil fuels as sources in this investigation. Using an indicator, BTB, they are able to detect the...
Curated OER
What Contains Carbon?
Students explore elements by analyzing everyday objects and materials in class. In this carbon lesson, students define several vocabulary terms such as carbon dioxide, hydrocarbon, and carbonate. Students view a group of items,...
Curated OER
The Greenhouse Effect
Why does it get so hot inside of our cars in the summertime? The greenhouse effect! Lab groups experiment to see what happens to an ice cube enclosed in a jar and placed in sunlight as compared to an ice cube outside of the jar. They...
Curated OER
Photosynthesis
Fifth graders work in small groups to brainstorm responses to a problem related to some disaster that wipes out half or all plant life on earth. Groups complete a graphic organizer to compare and contrast their ideas. Students select...
Teach Engineering
Breathing Cells
Pairs work together to determine whether unknown solutions are either acids or bases by using a red cabbage indicator solution. After determining the general pH of the unknown solution, classmates blow into the same indicator after...
Wild BC
The Greenhouse Effect: The Role of CO2
Though this is meant to be second in a two-part lesson, 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...
Curated OER
Dry Ice Activities Mini Lesson
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...
Curated OER
Ice Ages
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...
Curated OER
Breathing and Holding Your Breath
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...
Curated OER
Carbon Monoxide and Carbon Dioxide
A short slide show to illustrate the density of carbon dioxide and monoxide. An interesting look at the safety aspects to prevent CO poisoning, and the biological mechanisms by which it does harm. This elaborates on the exchange of blood...
Curated OER
Top to Bottom
Marine science classes read about the 2005 North Atlantic Stepping Stones Expedition and review climate change. They use maps to locate the seamount chains. In collaborative groups, they research how climate change may be altering the...

Dissolved Gases in Water
Using different types of water, earth science explorers set out to prove the ocean's ability to absorb greenhouse gases. They shake, heat, and freeze the water samples to examine gas content. This lesson is useful during a unit...
