Exploring Mass

In Room 4, we've been comparing objects to decide which is heavier and lighter. Firstly we learnt to heft (holding objects to judge weight) to compare objects. Secondly, we created our own balance with a cylinder and shoe box to determine which objects were heavier or lighter. Finally, we used a set of scales to compare our objects.  

 

We created our own balance similar to this one.

11th June - Comparing the weight of objects, "The play dough is heavier than the container. We will have to remove dough to come to the same weight."

11th June - Comparing objects, "The container of beans is lighter than the jar of paperclips."

11th June - Comparing objects according to weight and trying to balance the scales by increasing/decreasing the quantity of play dough.
