Lesson Five – Changing Solids

This science teaching pack for Key Stage Two gets the children to explore and record how to change the rate at which different solids can dissolve in water when completing a scientific investigation.
The class can explain and model how to perform a fair test to explore how using heat or speed might change the rate by which different solids will dissolve in a liquid.
Download this teaching pack including a lesson plan, classroom activities and an interactive presentation to explore and record how to change the rate at which different solids can dissolve in water when completing a scientific investigation
Activities in this teaching pack include display posters to identify and describe some of the different solids that can dissolve in water, a worksheet to conduct a test to identify ways to change the rate at which solids dissolve in water using heat and speed and a template to predict and record some of the different ways of changing the rate at which solids dissolve in water.
The interactive presentation gets the children to explore how to change the rate at which a range of different solids can dissolve in water.
This lesson is part of a science scheme of work to get the children to investigate, test and record how a range of different materials can be changed and altered including the use of dissolving and evaporation. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
