Modifying the Light-tracking bristlebot

Ask an Expert Topic Forum: Grades K-5: Physical Science

Modifying the Light-tracking bristlebot Modifying the Light-tracking bristlebot We have successfully built the light-tracking bristlebot. It was such a fun project! Will the circuit work if we replace the photoresistor with an IR sensor to make a heat-tracking bristlebot that will detect the warmth of a hand? Thank you! Re: Modifying the Light-tracking bristlebot Hi, There are different types of IR sensors, so in general it is not a matter of simply swapping out the photoresistor for an IR… Read more

Reducing Salt's Harmful Influence on Algae

Ask an Expert Topic Forum: Grades 9-12: Life, Earth, and Social Sciences

Reducing Salt's Harmful Influence on Algae Reducing Salt's Harmful Influence on Algae Hello! I live in Utah, fairly close to the Great Salt Lake. The Great Salt Lake is drying up rapidly, causing the salt content to rise dramatically. From the top of my head I know that salt can have a negative impact on the algae in the lake, which serves as a food resource for brine shrimp. So as the salt concentration increases, the brine shrimp population in the Great Salt Lake are threatened. How… Read more

Why is transparent specimen transparent?

Ask an Expert Topic Forum: Grades 9-12: Life, Earth, and Social Sciences

Why is transparent specimen transparent? Why is transparent specimen transparent? Could you tell me the reasons why the diaphonization looks transparent, that is, it allows light to pass through, from an optical perspective? I found how to create a transparent specimen, however, I do not understand the principles. Re: Why is transparent specimen transparent? Hi! Good question. The process of diaphonization is literally digesting tissues with chemicals (specifically an enzyme) that digest… Read more
