Science

This week, we have been investigating what happens to different materials when they are mixed with water. We observed which materials reacted to water, which dissolved and which floated or sank when mixed with water. As this was an investigation, we made our prediction on what we thought would happen when we added the following materials to water : salt, sugar, sand, baking powder and flour. Then, we thought about what we could change (independent variable), what we could observe (dependent variable) and what we had to keep the same (control variable).
