We started a new unit of study today. We are learning about Properties of and Changes in Matter. Students will be building an understanding of what matter is and reviewing the three states of matter (grade 2 study). We will conduct experiments to explore physical and chemical changes in matter and to look at important differences between when matter changes states and when it goes through a chemical change. In our study, we will learn about the environmental impact of chemical changes to matter and explore this from various points of view.
