Session Plan Focus: Dissolving sugar Year Group: Year 4 | | Learning Objectives:To understand that the temperature of the solvent (water) will affect the rate in which the solute (sugar) will dissolve | National Curriculum Links: | Key vocabulary: * Solvent * Solute * Prediction * Fair testing * Dissolving * Temperature | Prior knowledge: | Resources: * Post it notes * White board * Instructions sheets * Table of results sheet * Containers – each with 100ml of water * Sugar (white, granulated) * Teaspoons * Stirrers * Thermometers * Stopwatches * Health & Safety equipment * Maths Books/Graph paper (for extension work) | Planned Learning Experience: | Role of the…show more content…
Q’s: * what is dissolving? * What substances do we use on a regular basis which may dissolve in water? * What is the difference between a solute and a solvent (scaffold and guide answers if ch are unsure)Discuss any misconceptions which may arise from the above questionsDiscuss with children what factors may influence dissolving. Give ch post it notes to write down ideas. * Stirring * Temperature * Time * Amount/Type of solute * Amount/Type of solventAsk ch to put hands up and to call out ideas of factors which may influence dissolving and write them on the board. Tell ch that today we are going to focus on TEMPERATURE.Teacher will guide Ch to discuss in talk partners WHY and HOW they think TEMPERATURE may affect sugar from dissolving and then to feed ideas back to teacher and rest of ch.Ch to make predictions about what will happen to the sugars rate of dissolving in each temperature | The teacher will introduce the lesson by discussing with the ch about what they already know about dissolving. * What do the children already know * Any misconceptions * Any new ideas to be discussed * Teacher to make sure that temperature is discussed to obtain any misconceptions about temperature. The teacher will provide ch with post it notes to write down factors which they think may affect dissolving of sugar – make sure temperature is included. Teacher to write these ideas on the board. Teacher to explain what will be involved in the main session (see below). Recap with ch the importance of fair testing. Question the ch how it can be made a fair test. For each experiment: * Same quantity of sugar * Same number of stirs * Same temperature’s for each group * Same size containers * Same type of sugarTeacher to discuss the health and safety aspects of the experiment – very importantTeacher to tell ch which groups they are working in – mix High
