Science Day

Today I went to a science day at Cal Poly. We did biology, chemistry, and engineering.

For Biology, we learned about how taste buds work, and how they can be controlled. In chemistry, we learned about molecules, and how the molecular structure changes the smell/taste of an object. in engineering, we learned about sine waves, and how we can control the frequency of them, and make LEDs reflect the wavelength. My favorite was engineering, because it was the most in-depth, and they had a learn-by-doing theme.
