Project Idea
Smog days are often posted in your local newspaper. Check how many smog days your city has had in the last year. How does it compare to to other years? You can also take pictures of your city landscape on high and low smog days. How do the pictures compare? How does smog in the atmosphere affect visibility? What is smog made of? You can use tongue depressors smeared with Vaseline to check for smog particles in different areas; just stick in the ground and look at them a few days later. … Read more

thumbnail Have you ever wondered what a wildlife biologist does? Ronnie and Denise from DragonflyTV found out firsthand when they worked with a local wildlife biologist to take a survey of the fish populations in their local lake. They wanted to determine what the biodiversity (number of different species in a habitat) was like so that they could find out how healthy the lake habitat was. In this science fair project you can take on the role of a wildlife biologist by examining the biodiversity of… Read more

thumbnail How do astronomers collect stardust? They design and build satellites that are launched into space to collect particles on specially designed panels. Satellites can be sent to orbit around an object of interest: a planet, moon, or comet. In this experiment, you can build your own mini satellite and use it to collect some pretend stellar debris. If you simulate an asteroid impact, how much stellar dust will your satellite collect? Will placing your satellite at different "orbital" distances from… Read more

thumbnail If you had to choose between having your favorite dessert, going to a movie, or spending the night at a friend's house, which would you choose? This science project shows you how you can "ask" a sowbug (or pillbug) a similar question in order to learn about their preferences. Give it a try to find out what types of microenvironments these tiny crustaceans prefer. Read more

thumbnail Advertisements for high-tech sports gear or the latest and greatest outdoor material promise lighter and stronger products every season. Is it a scam? How can engineers keep creating materials that are both lighter and stronger than anything known so far? The answer is in the nanoscale! Using nanotechnology, scientists can play around with the detailed structure of matter, leading to a whole new range of materials, some with amazing qualities. In this science project, you will get a glimpse… Read more
