Quick summary: Students use chilled water to test the properties of beverage containers to hold either hot or cold drinks. They use their findings to explain their recommendations for which containers are best for being used for different purposes. They take into account the ability to recycle the containers then develop a video advertisement that demonstrates their learnings.
This lesson has been developed as part of the Schools Recycle Right Challenge for Planet Ark’s National Recycling Week. Register your lesson or other activities so they can be counted towards the national achievement and to receive other free support materials.
Learning goals for this activity include:
- Students plan experiments to find solutions to a given problem.
- They use the results of the experiments to recommend the best materials for beverages.
- Develop a communication project that makes recommendations that also include environmental factors.
Australian Curriculum content descriptions:
Year 9 Science:
- Energy transfer through different mediums can be explained using wave and particle models (ACSSU182)
- Plan, select and use appropriate investigation methods, including field work and laboratory experimentation, to collect reliable data; assess risk and address ethical issues associated with these methods (ACSIS165)
- Analyse patterns and trends in data, including describing relationships between variables and identifying inconsistencies (ACSIS169)
Syllabus Outcomes: SC5-5WS, SC5-6WS, SC5-7WS, SC5-10PW.
Time needed: 50 min
Level of teacher scaffolding: Medium – Students need to plan safe experimental procedures and look after equipment that is checked by their teacher.
Resources needed: A large source of chilled water to conduct many experiments. It may be easiest to buy a bag of ice and chill a large tub or portable cooler of water. Assume about two litres of water will be needed for each group. Equipment for measuring temperature e.g., digital thermometers, dataloggers with temperature probes, etc. A variety of clean beverage containers that are used for both hot and cold drinks. (Decide if this will or won’t include reusable beverage containers.) Have polystyrene and paper based coffee cups. Measuring jugs.
Digital technology opportunities: Data loggers, digital thermometers, video using mobile phone, tablet, notebook, etc.
There’s an app for that: iCelsius, a temperature probe, turns the iPhone, iPad or iPod touch into a digital thermometer. Requires separate hardware available from http://www.icelsius.com to operate. The app can work in demo mode if no probe is connected.
Assumed prior learning: Measuring temperature using units in centigrade with appropriate equipment, using equipment safely and, materials transfer heat at different rates.
Key words: Variable, boiling, temperature, rate, insulation, insulated, conduction, heat, energy
