Do your parents like to garden? Then you might have a beautiful lawn surrounded by flowers, or a vegetable garden. Humans have been introducing plants to our landscapes for centuries, which has dramatically altered the natural habitat of many environments. Chances are, the landscape you live in is not a natural landscape. One movement is to restore these habitats by re-introducing native plants. Conduct a survey in your area looking for native and non-native plant species. You can take… Read more

Ladybugs are common insects in North American gardens that prey upon aphids, making them all the rage in biological pest control. Ladybugs can be bred in captivity making them a good insect to study. Just chop off an aphid infested plant stem for food, make a water soaked cotton ball for water, and add to a small plastic container with a lid to make a breeding box. You can use ladybugs collected from the wild, or buy ladybugs from your local nursery. The most common species is the 12-spotted… Read more

Science Fair Project Idea
Germination is the process by which a seed emerges from the seed coat. Many different variables can effect the process of germination. Try to sprout seeds from different species of plant to see if different species vary in germination time. Are weeds faster germinators than vegetables? Try measuring seeds and then germinating them to see if big seeds sprout at a different rate than small seeds. Try sprouting seeds in different environments to test the effect of different environmental… 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

Survey your area to find out which species of plants and animals live there. You might be surprised to find out that something you grew up thinking was very common, is actually quite unique! For example, if you live in the great plains, then you may think that prairie dogs are a nuisance or a pest. Actually, some species of prairie dogs are only found here, and have a very important role for short and tall grass prairie ecosystems. The prairie dogs are an important part of the food-chain, and… Read more

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

Maybe this has happened to you: you're going shopping with one of your parents and the parking lot is really crowded. You're helping out, scouting for an empty space. You see someone heading toward their car, taking their keys out, and you point them out. At last, you're going to get a spot. You wait for the person to pull out so you can park. Does it take them longer because you're waiting? Do they move out faster? Or does it just seem that they do? For information on people's… Read more

Some plants grow only in water-logged environments. These plants are usually native to wetlands and are important for the sustainability of aquatic ecosystems. Wetland ecosystems are very fragile and susceptible to the toxic dumping of sewage and fertilizer run-off from neighboring farm land. One very common aquatic plant called duckweed inhabits many wetland marshes. Duckweed grows by asexual reproduction and floats at the surface of the water with tiny roots extending into the water below.… Read more

This project can apply to soccer, hockey, baseball and many other sports. What is the effect of stopping the kick/shot/swing at the moment of impact vs. following through? Think of a way to measure the outcome in each case, and explain your results. (idea from Gardner, 2000, 83-85; for more information with regard to specific sports, see: Barr, 1990, 12-14; Gay, 2004, 142-144; Adair, 2002, 30.) Read more
