Transcript: Part B: Interactive WB game ELABORATE STAGE Activity 3: Melting different solids. ACARA (2011). Australian curriculum: Science (online) http://www.australiancurriculum.edu.au/Science/Rationale BBC (n.d.). Solids and liquids. Retrieved 12, from http://www.bbc.co.uk/schools/scienceclips/ages/8_9/solid_liquids.shtml ENGAGE STAGE Activity 2. Making & melting icy poles 3. Students are provided with camera to photograph/video their work, a worksheet to record their findings and stop watches to record the amount of time taken to melt the icy pole. 4. Ensure students observe what happens to the fruit by questioning throughout the experimenting. 5. Students share and explain with the class what happened while conducting the experiment. Stage 2 Part A: Making icy poles. 1. The teacher will provide students with a procedure for making icy-poles. The procedure will not have the goal written on it. 2. It is up to the students to discover what they are making by analysing the ingredients, completing the steps involved and using their prior knowledge. 3. Students will then have a discussion. The teacher will ask questions such as: • What properties were used and can you describe them? • What can we do with what we have created? • What can we do with this liquid? 4. Class conclusion. Example: Ingredients used have made icy-poles and will be placed in the freezer overnight. Link: http://www.bbc.co.uk/schools/scienceclips/ages/8_9/solid_liquids.shtml Part A: 1. In groups, students are given a small hair dryer, butter and a plate. 2. They use thermometers to find out what temperature the butter will melt at. Science and Technology Outcome: Identifies that adding or removing heat causes a change of state between solids and liquids. ST2-13MW Numeracy Outcome: Use scaled instruments to measure and compare lengths, masses, capacities and temperatures (ACMMG084) 1. Students are blindfolded. 2. They touch and feel cornstarch. 3. Then describe and document the experience. Aim: Students gain an understanding and explain the differences between a solid and a liquid. References Year 3 Syllabus Outcomes: Part B: Melting icy poles. 1. Begin the activity up posing the question “Can we get the icy poles back to its original state?” (liquid). 2. Students then attempt to melt the icy poles using the following materials (discuss safety): o Hot water o Cold water o Hairdryer o Blanket o Ice & heat pack Topic: Material world Jessica Bozzetto, Rosa Vaccaro & Chantel Du Preez 1. Students experiment with different materials and temperatures. ENGAGE STAGE Activity 1. Cornstarch
