Build Your Own Lungs. Type Life Science Grade 5th – 7th Difficulty of the Project Medium Cost Safety Issues None Approximate Time Required to Complete the Project 10 – 20 minutes Objective Witness the process of how the lungs expand and contract with the help of the diaphragm.
Materials and Equipment/Ingredients Balloons(Grocery/Convenience Store) Clear Plastic 1 Liter Soda Bottles (Grocery Store) Tape (Hardware/ Office Supply Store) Rubber Bands (Hardware/ Office Supply Store) Y Shaped Tube Introduction Build your own lungs out of balloons and soda bottles. Terms, Concepts and Questions for Background Research Expand and Contract Pressure P.S.I. Research Questions What causes the balloons to expand? Experimental Procedure Cut the soda bottle’s bottom end so that it has a large circle on the bottom and the spout on the top. Put this balloon on the bottom of the bottle so that it covers the circular opening. To work the model, pull on the bottom balloon and watch as the 2 balloons on the inside of the bottle grow bigger. The Efficacy of Oral Rinses on the Accumulation of Bacteria in the Mouth. Comparison of Carbon Dioxide Production Before and After Exercise.
Cellular respiration is the process your cells use to release the stored energy in your food so they can use it.
This process is aerobic, meaning it requires oxygen to be present. The oxygen is used by the cell and carbon dioxide is produced. The body then gets rid of the carbon dioxide as you exhale. Problem: Understand that the production of carbon dioxide is associated with cellular activity. Materials: 2 beakers (or clear drinking glasses) 2 straws Stopwatch Bromothymol blue indicator solution Partner (optional) Soap, water, and towel Procedure: Place 60 ml of water (1/4 cup) in beaker #1.

Show That Fruits Contain Germination Inhibitors. What You Need to Know In reference to plants, an inhibitor is a chemical that blocks plant growth.
A germination inhibitor is a chemical that prevents the germination of seeds. How Does a Germination Inhibitor Work? Plants can produce their own germination inhibitors. The germination inhibitor produced by a plant prevents the germination of its own seeds until conditions are favorable for them to develop. What Does This Have to Do with Fruits? Most fruits contain germination inhibitors, which prevent the seeds from germinating while they are inside the fruit. Real-Life Science ChallengeInhibitors in one plant can prevent the growth of another plant. Experiment Now, start experimenting with ways to show that different fruits contain germination inhibitors. Hints The germination inhibitor might be in the seed coat or it might be in the flesh of the fruit. This article is brought to you by: Disclaimer and Safety Precautions.
