We have officially started our mixtures and solutions unit in science. This week, students set up and observed the materials that will be used for the next few labs. They included gravel, diatomaceous earth, and sodium chloride (NaCl). Feel free to ask your child to explain what these items are. You can even ask your child to pass you the sodium chloride or NaCl at the dinner table and you should be passed the salt. However, your child might ask you this before you get the chance.
