 Before we get started, let me clear something up.  Mass is not the same as weight!  Mass is the amount of MATTER an object contains.  Weight is a measure of the PULL OF GRAVITY on an object.  Today, we are working with MASS!

 5 plastic cups per group  Triple beam balance or pan balance  Gram stackers or paper clips if using a pan balance (*raisins, rice, beans, macaroni, cereal) or any 5 items that you have!

9/25 Cups and Stuff Pg# Pg # Raisins Beans Mac Rice Cereal (List the materials on each cup in the order you believe they are from heaviest mass to lightest mass. This is your hypothesis.) EX. Now graph your results. Question: What object has the most mass? Materials: Balance Cups Macarooni Cereal White Rice Counters Paper Clips (used to weight with) Hypothesis: I believe that ________ has the most mass because … I believe ________ has the least mass because… Hypothesis: (Draw your cups here.) (Draw another set of cups here.) Heaviest Lightest

 Pick up each cup and order them from heaviest to lightest mass.  Write down your order in your journal.  Now weigh each cup.  Write down the total mass for each cup.  Were you correct with your hypothesis?  Now graph your results.

 How did your “lifting results” compare to the actual results?  Use the terms “greater than” and “less than” when writing your observations.
