Random shot of a family at the Science Fair today. My husband judged the top 8 seventh graders and I judged the top 8 eighth graders.
Top 8th grade projects (and I’m writing this from memory after observing 8 presentations! )
Bluberrific Antioxidants – The correlation between vitamin c and antioxidants. The student was inspired because by his mother who makes a lot of smoothies. He found that you lose the benefits of blueberries by combining them with citrus fruit.
How humidity affects the growth of Chlorella lipid output. The student had access to a lab, centrifuge and cake press (?). He found that 80 % humidity causes algae to put out the maximum amount of lipids that can then be used as biofuel. At least I think that’s what he said.
Inspired by Sherlock Holmes, this student attempted to determine if the stuff you use to keep your fish Ick disease-free (malachite green + sodium chloride) was a better indicator of blood than hydrogen peroxide.
Very impressive and appeared to be mostly student-done. (You teachers know what I mean!)
I really enjoyed using autostitch, so here’s a bonus shot of the Science Fair – panorama style.
