Your students can uncover a substance that affects ice with this investigation.

The resource includes a clear outline of the equipment needed and the steps, along with scaffolded worksheet pages that target the Australian Curriculum Year 5 Science Inquiry skills. By timing how long it takes for ice cubes to melt when they have various substances added to them, your students should discover that salt causes ice to melt the fastest. This is because salt lowers the melting point of water. Your students will consider the implications of this finding when dealing with dangerous icy surfaces.

To help with differentiation, the worksheets include a duplicate page with a data table template included and a duplicate page with graphing axes and labels. When you have decided which versions of the worksheet to give to which students, you can print the number of copies that you need, gather the simple equipment and begin the investigation.

This resource is part of our Chemical Sciences Year 5 UNIT PLAN.
