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...

Pair earth scientists up to use an amazing online arctic portal mapping tool and Google Earth to analyze permafrost changes. They compare changes to data on atmospheric concentrations of methane to see if there is a correlation. Then...

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...

Students carry out an experiment to monitor diurnal fluctuations in dissolved oxygen, carbon dioxide, pH, and water temperature. They determine the CO2 and pH of the samples (and optionally, dissolved oxygen). Students complete their...

Students review the objectives for the light and dark reactions on photosynthesis. They discuss the conversion of Carbon dioxide to simple sugars occurs in the light independent reactions. Students are given the question of the day. ...

In this carbon cycle lesson, middle schoolers review the carbon cycle and visit stations in the room where they experience every phase in the carbon cycle. Students journal about their journey through the cycle and brainstorm ways...

Students examine the different techniques that may be used to reduce carbon dioxide in the atmosphere.  In this ocean pollution lesson students divide into groups and complete a lab to see how the ocean holds carbon dioxide.

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...

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...

Biology classes will bubble with excitement as they complete this assignment. Beginning with an informative overview of cellular respiration and fermentation processes, the highlight comes as an experiment in determining the rate of...

In this gases worksheet, students conduct an experiment to produce 2 different gases and use standard tests to identify each gas. This worksheet has 14 short answer questions.

Seventh graders identify how much carbon is held by the world's forests. For this forestry instructional activity, 7th graders study the carbon cycle and discuss what role humans have had on climate change. Students write a one page...

Seventh graders learn how trees help nature recycle.  In this carbon cycle lesson, 7th graders view a picture of a giant redwood tree, complete a Think, Pair, Share activity, view and discuss a poster about how nature recycles,...

Eighth graders research the Greenhouse Effect on the Internet. They use a variety of sources and take notes on the topic. They use ClarisWorks to type a report, use spellcheck, proof and edit. They can create a class bulletin board.

Students work in groups to research biomass using the International Energy Agency's website. Students use evidence from the web search to assess biomass energy potential in Pennsylvania as part of a classroom "Alternative Energy...

Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...

Here's a five-star lesson plan in which inquisitors conduct sophisticated experimentation with cellular respiration in plant seeds. Placing seeds in a closed system they measure the amount carbon dioxide produced and relate it to...

Young scholars perform a series of experiments which show that plants require nutrients in certain quantities. They also cooperatively read materials on the nutrient requirements of plants, fertilizers, composting, and soil management,...

Students observe an experiment.  In this science lesson, students watch an experiment where baking soda and vinegar are used to blow up a balloon.  Students answer comprehension questions about the experiment.

Fifth graders determine that carbon dioxide is a gas given off during respiration and that oxygent is the gas that is absorbed during respiration. They determine the air capacity of the lungs.

Students conduct experiments designed to detect the presence of CO2 by using a BTB that changes color (blue to yellow) in the presence of CO2. First, students experiment with the CO2 from combining vinegar and baking soda. In part two,...

Students research and investigate the concepts carbon cycle and fossil fuels. They graph the carbon dioxide production as well as populations of six nations. Together they generate a variety of recommendations to reduce travel=related...

Show the six-minute video, "Changing Planet: Fading Corals," and then demonstrate how calcium carbonate forms a precipitate in the presence of carbon dioxide. Separate your scientists into small groups to gather information about coral...

A kaleidoscope is constructed using polarizing polymer paper and then low-density polyethylene, high-density polyethylene, and polypropylene are all melted onto individual glass slides and examined through a microscope. The intent is to...
