Science in 4th Grade: What a Mess!

4th Grade worked together this week to solve a very real problem.

The pots of sand, sugar, iron filings and gravel that they needed for their science experiment tipped over and were mixed up!

They had to apply their knowledge and understanding of the properties of materials to sort out this mess.

Firstly they sieved the gravel out of the mixture and then used a magnet to separate the iron filings. Next they added water to the sugar and sand and filtered the solution to separate the soluble sugar from the insoluble sand.

Finally they waited for the water to evaporate, leaving behind the sugar crystals.
