Summary:This week in class we learned about chemical changes. A chemical change happens if something is done to make a new form of matter, some examples are: ( I know this one might sound a little weird but it is true.) farting, evaporation, and when a star collapses on itself and becomes a black hole. There is another type of change in matter and it is called a physical change. physical changes happen when the matter looks different but is the same matter as before some examples are: moving my arm up and down, ripping a piece of paper, and digging a hole in the ground. Fun Fact: There are actually 5 states of for chemical changes to happen to!
SP3: Planning and carrying out investigations
We planned an investigation by setting up these two plates with holes in the and we put things like baking powder and baking soda. we carried out an investigation by mixing them with liquids like vinegar and water. In the end we got results.
