Integrated Science – Day 4
In the morning, our budding scientists did more tests of the effects of pollutants on daphnia, and they also investigated the effect that adding a solute has to the freezing and boiling point of water.
In the afternoon, they put the knowledge gained through the freezing/boiling point lab my making ice cream in a bag by lowering the freezing point of the ingredients through the use of salt. Students also worked on the presentations they will be sharing when parents visit the lab tomorrow (Friday) afternoon.
Ask your student: what are the colligative properties of a solution?
