5th class find out about starch.

on May 22, 2016

During Science this week we learned about starch in different types of food. We used some iodine and got some different types of food. We used a pipette to add a few drops of iodine to each piece of food. We made ┬ásure that we put the same number of drops on each piece of food. We had to observe and then record any changes. We recorded any changes in a table in our copies. We discovered that if starch was in a piece of food it would turn a blue/black colour. If it wasn’t it stayed a yellow/orange colour. Have a look at some of our results.
