What can i do to level up or do something novel about it? [Administrator note: project:… Read more
simulating toxic water simulating toxic water I have a student that wants to use bioluminescent bacteria as a water pollutant indicator. We are focused on heavy metals, specifically Cu, Cd, and Pb. To create known concentration solutions of each of these metals (I plan to have her start at 1M and do a serial dilution), would I have her use metal salts or is there a better way to toxify the water? Thank you. Re: simulating toxic water Metal salts are definitely the best option! These salts… Read more

shoes for the visually impaired shoes for the visually impaired [b][i]I want to design a shoe for the visually impaired and I plan to make obstacle sensors on the ends of this shoe and a speaker that tells where to go based on obstacles or a sensor with an audible alarm that detects obstacles. What do you think I can do? I also thought about it, could there be a Bluetooth headset that tells where to go with an obstacle sensor? Can you support you? OR WHAT MORE CAN I IMPROVE?

Tiny titans E coli didn't grow Tiny titans E coli didn't grow Good morning, Last week my son performed the Silver nanoparticles neutralizing E coli experiment. Even though we followed all the steps in a college lab where we used an incubator, the E coli did not grow on any of the agar plates. We are not sure whether the freeze dried E coli we used was not a good sample or the agar plates were not optimal or unknown reason. The instructions for reconstitution of E coli were conflicting. On… Read more

egg drop egg drop Would socks and a plastic container with lid on, be a good material for a protective shell for the egg drop? I'm dropping the egg from 5 feet, 7 feet, and 9 feet. I'm supposed to find and answer for the question but I can't find anything. Re: egg drop Hi! Egg drops are super fun! You have the right idea of padding the eggs fall with the socks, which slows down the impact on the ground. Something you should consider is that there are two ways to minimize the force of the… Read more
