Grade 8s will have their first test on the Hydrosphere Wednesday. They received their review sheet which contains real questions from a previous End of Grade test. Most tests will have some multiple choice questions from a previously released EOG so students can get practice answering these type of questions.
Students enjoyed the "Properties of Water" lab. Our latest adventure was calculating the density of various objects. The student helpers of the month measured water in a beaker and calculated the amount of displaced water when we put in the object. They weighed the object on the scale and then divided the object's mass by its volume to get the density. We compared the different density of the objects tested. Students could see by this hands on activity that the cotton ball actually was less dense than the metal bolt and piece of wood.
This week we will begin studying the ocean, its parts, its dissolved gases and minerals, and marine life found there.
