Now that you have secured your location and created a way to get cleaner water, it is time to think about food. Sometimes it will be easy to make a fire and sometimes that might not be your best option for cooking food. In some cases, a solar oven could come in handy. Compare and contrast a solver oven versus a fire to cook food below.
As well as designing and building your own solar oven, your group need to research various types of energy sources, particularly those we use in Scotland.
Solar power is one source of renewable energy, however there are other sources as well as non-renewable energy sources. In your group, use the links below to answer the following questions:
1.Identify renewable and non-renewable sources of energy and give an example of how these are used in Scotland.
2.What is another name for coal, oil & natural gas?
3.Name some positive and negative global impacts of using non-renewable and renewable energy sources.
4.Where do we get most of our electrical energy from? How is it transferred to our homes?
5.Suggest ways in which we can reduce our own energy use and live more sustainably.
This afternoon, we had to build a fence with a gate that opens and closes so we can go out for supplies. We used the engineering design process to help us work through our ideas. We had some materials to use and criteria.
Your gate must open and close with a latch.
Your fence must have a perimeter of least 10 cm.
Your fence must stand on its own and be at least 7 cm high.
Check the Engineering Design Process below
Every member of your team must contribute (suggest ideas)
Every member of your team must have a role (Facilitator, Resource Manager, Time Keeper, Quality Checker)
Identify the problem: What is the problem the challenge wants you to solve?
Identify the criteria and constraints. What are the rules of the challenge?
Brainstorm possible solutions. What are some ways you can complete this challenge?
Generate ideas. What are some materials you can use?
Sketch a couple of ideas.
Select an approach. What design did you pick? Why?
Build your model or prototype. Does your design work?
Refine the design. What changes did you have to make, if any?
