Our forests are a very important natural resource that need to be managed wisely. We use wood products for many different purposes: building materials, paper, cardboard, furniture, fuel, etc. How can we use wood products in a sustainable manner? You can do experiments that examine the growth time of different tree species to see which are good candidates for tree farming. Which types of lumber are most sustainable? You can also compare the effects of clear cutting vs. thinning a forested… Read more

It is important to ensure that we all have good clean water to drink that is not contaminated by heavy metals or chemicals. One common pollutant in a water supply is lead in old pipes or paints that can leach into the water and cause lead poisoning. There are different kits available for testing the presence of lead and other contaminants in water. Test your water supply, and also the water in some local ponds, lakes or streams. The same contaminants that can harm you can also harm wildlife. … Read more

Visit your local landfill to collect dumping statistics by watching the types of trash people bring to the dump. Identify problem areas and types of waste that are commonly brought to the dump. Propose new uses for common landfill problems like tires, construction materials, plastics, appliances, and computer parts. Measure packaging materials of some common products. Invent ways to reduce the amount of packaging and increase the use of recyclable materials like popcorn or corn-based packing… Read more

Some plants use a lot of water, and some are very drought-tolerant. Drought-tolerant grasses are good for water conservation because they require less water to grow and stay green. How much less water do they need? Which types of grass are drought-tolerant? You can buy different types or brands of grass seed at your nursery that claim to be drought-tolerant. Grow them in a container and then starve for water after they are established. Which brands die out first? You can conduct a similar… Read more

Science Fair Project Idea
You've seen that a magnet's attractive force can cause a small object (like a paper clip) to "jump" to the magnet. So a magnetic field can act through the air, but what about other materials? Here's an experiment you can do to find out. You'll need a strong bar magnet, a stack of books, a paper clip, some thread and tape. Place the bar magnet underneath the top book in your stack, so that it sticks out. Tie a piece of thread (as long as the stack of books is high) to a paper clip. You… Read more

Plastics are made of polymers, chemical structures containing many repeated subunits. How does the polymer type of a plastic affect the biodegradability of the plastic? Do research on how plastic is made and what types of polymers are used for making different plastics. Can you learn to make your own plastic? What materials can you use for making plastic that is biodegradable? Test biodegradability by burying plastic samples for different lengths of time. (Kadar, 2004) Reducing solid waste… Read more

Make your own fertile soil using kitchen scraps, manure, leaves, grass clippings, and other compostable materials. Which materials make the best compost? How does the amount of nitrogen change the rate at which the compost forms? How does traditional composting compare to worm composting, or vermiculture? How does the temperature of the compost pile change? Read more

Some plastics undergo an unusual transition, from a hard, glassy state to a soft, rubbery state, with increased temperature. For this project, you should do background research on the effects of temperature on different types of plastics. Make sure that you understand the difference between thermosetting and thermoplastic polymers. You should also look for information on the glass transition temperature (Tg) for different plastics. Pure polyvinyl acetate has a Tg of 28 C (about… Read more

There are three different kinds of polymers used for kitchen plastic wrap: low density polyethylene (LDPE) (e.g., Handiwrap or Glad Wrap), polyvinyl chloride (PVC) (e.g., Reynolds PVC Foodservice Wrap or Boardwalk PVC Food Wrap Film) and polyvinylidene chloride (PVdC) (e.g., Saran Wrap, which is almost 90% polyvinylidene chloride). Which of these materials is least permeable to oxygen? When you slice an apple, the surface of the slice turns brown as the apple is oxidized. Can plastic wrap… Read more
