Welcome to the YES-2-Tech blog. Below you will find comments from both teens and staff about their activities in the program. Enjoy!
This week we have done several things like work with the fish in the fish tank and worked with trying to figure out how to make a pump work and what inside it makes it work the way that it does. So first Frank, Josh, Robert, and myself took twenty five percent of the water out of the tank and refilled it back with tap water. And the reason that we took only twenty five percent of the water out was because if we took more than that out then the fish could most likely die because of the sudden change so we decided to change the water only once a month so the fish can get used to the changing of the water. Then after that I tested the level of the ammonia, nitrate, and nitrite levels in the water and so far the levels of nitrate and nitrite are very low at 0ppm and the ammonia levels are still pretty high at 0.25ppm. But we have to find a way to lower the level of ammonia in the water and raise the level of nitrate and nitrite in the water so the fish can survive for a long period of time.
Then after we got done experimenting with the fish we saw that the hand pumps that we use everyday are connected to the electric water pumps that we have in fish tanks. And the way that they are all connected is because they each have a piston that builds up the air pressure in for example a water gun so you can have a long shooting range from the water. And then we also learned that the way that the electric pump is different is because when it is plugged up and started then it runs on its own. But when we took these hand pumps apart we saw all to the parts of the pump that makes it go and work for anything that you want to work like a soap dispenser and a trigger spray. So go home and take apart anything that you can use that is a pump....but ask your parents before taking things apart or just completely breaking things.
