You’ve picked the perfect project, pulled together your materials and variables, conducted your experiment. You can see the finish line. But there is one last piece of the science fair project that remains…the project display board.
I’ve been surprised in my working with students and their parents that the display board can make even the most confident scientists to break out in a sweat.
Don’t sweat the display board – this is where your hard work and creativity really get to shine. It is a display that tells the story of all of your efforts and gives the first impression of your project.
Here are a few tips:
Keep it simple, neat and organized.
Start with a powerful title. You want to grab the judges’ and visitors’ attention. A title like “Mentos and Diet Coke Geysers” is nice, but it doesn’t jump out. Try something like “Icky Sticky Soda Geysers – Which One Makes the Biggest Mess?”
Use your imagination and make it attractive. Use pictures, 3-D objects, colors, graphs, charts or illustrations to draw in your audience.
I love Halloween. One of my favorite activities is to “carve” pumpkins using a simple reation inside the fruit. First, you carve the face then carefully replace pieces. After creating a reaction by generating a gas inside and igniting it (ask your local chemistry teacher for the details) the face pieces are blown off with a small explosion.
Halloween is more than 100 days away and I just couldn’t wait. So I initiated the new weather anchor at the local Denver television station by introducing her to carving watermelons. The problem was, we didn’t really carve the watermelon, it exploded. Watch the Video to see how we skipped right over the carving and went straight to exploding.
Not exactly… but this stuff is really cool. It’s probably best described as a self-siphoning gel. The chemical is called polyethylene oxide or Polyox and it has an incredibly large molecular weight – about 4 million. When the powder is mixed with water (that’s the tricky part), the liquid becomes very thick and will literally siphon itself from one container to another. As a kid I order a product called Moon Blob – “The Gravity Defying Gel” – which promised to do the same thing. It did… but now I’m doing it as an adult! It’s tough to explain it… just watch the Polyox video.
If you’ve ever enjoyed wearing a bottle of Diet Coke after dropping in a roll of Mentos, you know that the reaction is immediate. I’ve always thought that it would be cool if you could slow everything down and really look at the reaction. I shared the idea with our friends at Mentos and they shot this slow motion video. There are a few frames where you can see the carbon dioxide gas coming out of solution being attracted to the tiny pits (nucleation sites) on the surface of the mint. For the tech-nerds in the audience, a Phantom 9.0 high-speed digital camera from Vision Research (2,000 frames per second) captured the slow-motion footage.
Only a very cool teacher gives this kind of homework to her students… “Using only construction paper and tape, I want you to design a rocket.” Lisa Heaton, the Gifted and Talented teacher showed her students a specially designed rocket launcher made out of PVC plumbing parts from the local hardware store. The idea for the PVC rocket launcher comes from U.S. Space Camp for Educators curriculum. I had the privilege of assisting Mrs. Heaton with the launch of the paper rockets. As the students will share in the comments below, the first launch revealed their design strengths and flaws. The five students with the best launch served as mentors for the rest of the students as they returned to the classroom to repair and redesign their paper rockets. The second launch proved to be the real learning experience – be sure to read comments from the young rocketeers below.
“This rocket launch activity coincides with the students reading Rocket Boys (also known as October Sky) by Homer Hickam. I want these kids to experience first hand the feeling of failure and success
