The past few years, some co-workers and I volunteered to judge the science fair at a local elementary school in Raleigh. It was always so much fun to see the students getting involved in science and doing their own experiments. (and the free lunch and half day off work didn't hurt either!)
So when I came to Carachipampa, I thought it would be fun to have a science fair here! I wanted the students to see that there's more to science than just the specific subject they're studying in class. The science fair is a way for them to focus on a particular area of science that they enjoy and to explore God's creation. Scripture says "How many are your works, Lord! In wisdom you made them all" (Psalm 104:24).
I talked to John, our director, and he was very supportive of the idea. He said they've never had a science fair since he's been at the school, although one of the other teachers said they had a science fair sometime in the 90s. So in December, I started planning the fair, with a lot of help from Beth, who teaches 7th and 8th grade science.
The students learned how to design and perform their own experiment based on the scientific method. They also learned the three types of variables in an experiment, how to write a science fair report, and how to prepare a display board. Running the science fair was not without its challenges: I had to rearrange the topics I was teaching to allow time for science fair and I spent a lot of one-on-one time with students discussing their projects. Since most of the students had never done a science fair project, there was a steep learning curve for them. But they worked very hard and did a great job!
The science fair was supposed to be March 12th, but we had a week of paros (school was canceled due to streets being blocked by protesters) and then the seniors and I were out of town for a week on their senior trip. So we were finally able to have the science fair this past Monday, the 26th.
I was so proud of the students. Their projects turned out well, and the displays looked great. The best moment for me was watching my high school students interact with the elementary students. Even some students who don't like science were actively explaining their project to the little kids, who were fascinated!
Here were some of the science fair project topics from my 9th-11th grade students:
- Testing organic vs. chemical fertilizer on plants
- Testing the performance of a motorcycle vs. a 4 wheeler (!)
- Determining whether a hamster or guinea pig runs a maze faster
- Using electrolysis to split water into hydrogen and oxygen
- Building an electric motor and testing different brands of batteries
- Finding the best design for a bottle rocket
- Determining the sugar concentration in water based on the angle of refraction of a laser
- Determining whether liquids of different pH's preserve meat better (I'm sure their parents loved having rotting meat around the house)
And Beth and Max's students had some great projects. The 12th graders, who are taking physics, built a crossbow, a ballista, and a water wheel! One of my favorites was the overall winner for 7th-8th grade (You can probably guess why it was one of my favorites :). He showed how vibrating a violin at different frequencies creates characteristic nodes and patterns in the wood. Very cool.
Here are some pictures below, and there are more on facebook.
