Today in science class we did a lab for the very first time. We had to wear goggles and we got to mix stuff it was really fun. I was confused because I didnt get why my tables bag didn't do anything. We poured half cup of water into the glass and then Mrs. Rousseau came and put some drops of idoine into our glass then we put the bag inside the glass and it didn't do anything. The bag did not change colors it didnt do anything. I wonder if it was because my group did something wrong or if there was something wrong with the bag. A question I have is what does the idoine do? what was the whole purpose of it?
