This week in science we finished our tests and put a finish on our chairs. So that they last longer and they are very shiny, we also started working on our digestive journey projects and we watched a video about this weird dude and looked at some other people’s slides that they had done. Then after that, we did an experiment with saltines where you crush one of them up in your hand and you chew the other one for 3 minutes, it was really gross but then you put 30 MLS of water into each of them then you put in a chemical and it changes the color and the one that was chewed was a lot lighter because of all the chemicals in our mouths that are used to digest the food and the crushed one was darker.

How do the chemicals get to our mouths?

How does the color part work?

was this a new experiment?
