First grade students had a great time putting various solids (raisins, rice, sugar, cookie, cloth, popsicle stick, chalk, beans, plastic cube, and salt) into containers of water. The recorded results after 5 minutes on paper and then 24 hours later they divided the solids into groups using Tools4Students based on whether the solid dissolved, became mushy but still visible, or stayed in the original solid form (noting changes that did occur such as looking darker). In addition, students each picked a solid and created an Educreations explaining what had happened to their solid.

Students removed as much of the water as possible from each solid and graphed on the whiteboard how many days it took for all the water to evaporate from the different solids.
