Science Fair Project Idea
Try gluing wood together with different types of glue, e.g.: regular white glue, yellow wood glue, cyanoacrylate (super glue), and Liquid Nails. Glue a short piece (5-8 cm) to the center of a longer piece (15-30 cm). After the glue has dried for the recommended time, drill a small hole through the center of the joint, big enough to pass through a piece of coat-hanger wire. Cut a length of coat hanger wire, pass it through the hole, and twist the ends together to form a loop. Place the ends… Read more

If you like to fish and you'd rather not be telling the story of "the one that got away," then this is a project for you. What combination of properties makes for the best fishing line? Here are some suggestions for getting started on your background research into fishing line properties: knot strength, abrasion strength, shock strength, tensile strength, limpness, controlled stretch, and desired range of visibility (Dodson, 2006). Choose the properties that you think are most important, and… Read more

How strongly do different types of nails hold in wood? Try different diameters of nails, and try pounding them to different depths. To gauge the holding strength, measure how difficult it is to remove the nail. Can you pull it out with a pair of pliers? Can you remove it with the hammer claw? Do you have to push only a little bit, moderately hard, or as hard as you can? Do you need a crowbar? What happens if you pre-drill holes for the nails, using drill bits that are different… Read more

Science Fair Project Idea
The different species of wood used in construction offer a variety of challenges based on density, porosity, oils in the wood, flexibility, elasticity, etc. The intended use, e.g., structural or cosmetic, presents different challenges as well. The glue must be compatible with the wood, the use, and the climate, so many experiments are possible. For example, you could design an experiment to test the durability of different adhesives using the same wood. Or, you could try different wood… 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

What is cloning and how is it used in the biotechnology industry? How are plasmids constructed for use in a bacterial expression system? You can investigate bacterial expression with the from the Bio-Rad Biotechnology Explorer Program (see the Science Buddies project, ). With variations to this kit you can test the conditions for pGLO expression under different conditions. You can also combine with other kits to map the pGLO plasmid and purify the expressed pGLO protein using column… Read more

Prerequisites Some laboratory experience is required: knowledge of sterile technique, working with bacterial cultures, and using automatic pipettes are all helpful.
Material Availability In the Summary tab change the Material Availability field to read: This science project requires the purchase of Bio-Rad's [# Link Name="BioChem_p035.6" Value="HtmlAnchor" #]. You will need a teacher's help to order the kit as Bio-Rad only sells directly to schools.
Cost Very High (over $150)
Safety Adult supervision is required in the laboratory facility. Use sterile technique. Read the [# ProjectGuide Name="Advanced.MicroorganismsSafetyGuide" Value="HtmlAnchor" HtmlShortTitle="true" #] before starting any experiments. [# ProjectGuide Name="Advanced.ScientificReviewCommitteeSRC" Value="HtmlAnchor" HtmlText="SRC approval" #] may be necessary.
