Materials needed: triple beam balance, graduated cylinder, ruler (cm), small cups, water, dropper (optional to get water level as accurate as possible), clay
This was such a great activity to do with my sixth grade students. It reinforced the concepts of volume (lwh), density, mass, measurement and finding volume through water displacement. You get a lot of education going on in one lesson. The kids love it and it is a very hands on activity. Enjoy!
