Teaching Idea 2: Investigate Passive Solar heating
This teaching idea has been suggested as it links to the lesson suggestions for Year 6 Design and Technologies (sustainability and community - solar cars), the effective use of the sun's energy. The lessons below have been suggested in order for students to recognising the need to carefully plan and select components for a system to perform a specific task, design a house using passive solar. In passive solar building design, windows, walls, and floors are made to collect, store, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer. This teaching idea can also be linked with the lesson suggestions for Year 6 Digital Design (Google Sketch Up).

Teacher Background:
" Some buildings are designed for passive solar heating, and do not need a solar collector. Basically, passive solar heating is when opportunities are made for the sun to shine into the building to warm it up. The walls and floors are made with materials that absorb and store the sun's heat, and they heat up during the day and release the heat at night. This is called direct gain. In cold places in the northern hemisphere big windows are put in the south side of the building, letting in much sunlight. The inside of the buildings are therefore well lit, further reducing use of electricity. Heating bills can be half the size of those for a building requiring electrical or other heating. Building designs make sure that the longest walls run east to west, to allow more sunlight to enter in winter than in summer, with shades and overhangs to reduce summer heat" (source).

Lesson 1: What is passive solar?
Teachers will need to explicitly teach students what passive solar heating is. The resources below might be useful.
Solar Energy: Understanding active and passive solar hearing
Teachers may also choose to conduct a passive solar heating experiment if they have access to parked cars. Here is the LINK.

Lesson 2: Design brief
This teaching idea is linked directly to the teaching suggestion for digital design, Google Sketch Up: Design a passive solar heated home.
Inform students that they are designers and they have been asked to design a passive solar heated home for a potential client. They need to generate, develop, communicate and document a graphic design idea for a passive solar heated home. However, before they begin their design there are series of steps they need to complete in order to achieve their goal. Furthermore, designers (students) have the option to work individually or collaboratively in pairs.
Step 1: Remembering
Locate information about passive solar heating and write a list of the key elements.
Step 2: Understanding
Create a PMI chart for passive solar heating and regular home heating in order to compare the advantages and disadvantages of each.
Step 3: Applying
Produce a list of design features that you will include when designing your passive solar heated home.
Step 4: Creating
Use Google Sketch Up to design your your passive solar heated home.
Step 5: Analysing
Explain how your design incorporates passive solar heating and compare your design to at least two of the other designs (peers). Propose at least three possible in which your design could be improved.
