Science Fair Project Idea
Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether the kid standing next to you is your sister or your cousin? The biologist might be able to make some good guesses this way, but by using samples of your family's DNA, s/he could construct your whole family tree. In this project, you'll use Web-based computer… Read more

thumbnail Animals survive in all sorts of extreme environments, whether it is a polar bear out and about when it is -40°F, a desert iguana trying to find food as the temperature rises to 110°F, or a deep sea anglerfish living 3281 feet down into the sea. How do they do it? The answer is adaptations! Their bodies have special features that allow them to live in those environments. You might not be able to dive down 3281 feet to observe the deep sea anglerfish, but in this science fair project you… Read more

Science Fair Project Idea
Antlion larvae are known for their predatory ways. In sandy areas, they dig pits to trap ants or other crawling insects that happen to stumble in. This project shows you how to create a mini-environment for antlion larvae to test their preferences for pit-building sites. Read more

Science Fair Project Idea
Animals have different levels of activity depending upon their habitat, metabolism and behavior. Diurnal animals are more active during the day. Nocturnal animals are more active at night. Being diurnal or nocturnal may have different advantages for different animals. For example, desert animals tend to be nocturnal so they can stay cool and escape the desert heat present during the day. What types of diurnal and nocturnal animals are common in your area? You can set out a small trap to… Read more

Safety If you choose to try trapping small animals, adult assistance will be necessary. Avoid touching wild animals. Seek immediate medical attention if bit by an animal.
Science Fair Project Idea
thumbnail Have you ever been to a tide pool during low tide? Some intertidal animals in the low tide zone are left in a tiny pool of water when the tides go out. Other intertidal animals that live in high tide zones may be left to dry out during low tide. How much time does each zone spend out of water during a tidal cycle? Read more

Science Fair Project Idea
thumbnail Have you ever stopped to watch a trail of ants moving back and forth between a food source and their nest? Have you ever wondered how they establish their trail? You've probably read that ants use chemical signals to communicate with one another. This is a relatively simple experiment that you can do to determine whether ants use attractant signals (positive cues) or repellant signals (negative cues) or both. Read more

Time Required Average (6-10 days)
Prerequisites You'll need an ant colony to do this experiment (outdoors is fine).

Science Fair Project Idea
thumbnail "How do you frighten a grasshopper? And what does that have to do with light?" These are a couple of questions you're probably asking yourself after reading the title. Well, The Frightened Grasshopper Solar-Powered Bug is actually a toy grasshopper that vibrates when it is placed in sunlight or near a lightbulb. It stores up the energy from light, and converts it into motion. You will use this fun toy to explore how the brightness of the light affects the motion of the solar-powered insect. Read more

- Less Details
Time Required Very Short (≤ 1 day)
Prerequisites None
Material Availability The Frightened Grasshopper toy needs to be ordered from online. See the Materials and Equipment list for details.
Cost Low ($20 - $50)
Safety Adult supervision is required. The lightbulbs will be hot, so use caution to avoid getting burned by the bulbs. The Frightened Grasshopper toy should be assembled with the help of an adult since it is fragile and has some small parts.
Science Fair Project Idea
thumbnail The first land animals took their tentative steps out of the ocean and onto solid ground around 365 million years ago. Over millions of years, these early ancestors developed into tetrapods, including amphibians, reptiles, dinosaurs, birds, and mammals. Then, around 50 million years ago, the reverse process occurred: the mammalian ancestor of today’s whales returned to the ocean. In this genomics science fair project, you will use mitochondrial protein sequencing to trace the evolution of… Read more

Science Fair Project Idea
thumbnail All animals have a genome, but do they all have genome projects? Find out which animals are currently having their genomes sequenced and how much we know already. Whose genomes are already finished? Whose genomes are just getting started? Find out by doing some simple bioinformatics data digging! Read more

Science Fair Project Idea
thumbnail Why do birds migrate? Do all birds have the same reasons for migrating? Where do they go when they migrate? These are questions scientists have asked for centuries. The more species for which they gather data, the more specific the answers become. In this science project, you'll choose a species to investigate, then access and evaluate real data collected by scientists to start answering those questions yourself! Read more
