Science Investigation on Density

By /
Density Column
Description: We want to introduce the concept of density to the junior secondary level start out simple, therefore, we create two activities to show density in liquid form and solid form. A column of density can show liquid density cleanly. In the second activity, we use table salt and straw to do an experiment showing solid density. Through observation of sinking and floating objects, the relationship between volume and mass is shown.
