Harness the Sun!

Most of us are aware of the benefits of using solar-powered devices - it reduces our electricity bills and it is eco-friendly, as we use a natural resource - the sun! But few have stopped to actually consider the life-changing effects for example solar cookers can have on women and children in many developing countries. Namely, many women and girls spend hours on end collecting wood, tending fires and cooking with wood stoves in different countries. This influences girls’ school attendance, among other things. Water-borne and smoke-related diseases are among the primary causes of death for children. The smoke from cooking on fires is also a major cause of death for young women in many parts of the world.
Solar cookers are arguably among the best alternatives when it comes to improving children’s school attendance (zero time spent on collecting burning materials and much less attention needed to watch over the meal as it is being cooked!), no smoke is generated leading to significantly improved health and poverty reduction overall as many more families are able to cook their own meals with significantly lower bills.
In the following activity, we will try to create our own little household solar cooker.
Individual or group / Experiential
To learn how to build a solar cooker
Reflect on alternative sources of energy
Reflect on how spreading such alternative energy concepts could be life-changing for poorer communities
Required Materials and Tools:
2 cardboard boxes
Glue or staple
The instructions are adapted from WikiHow. Please refer to the link provided for a clearer guidance with pictures.
Put a cardboard box inside a bigger cardboard box. There should be at least an inch between the sides of the 2 boxes, fill that space with shredded newspaper (insulator). In order to absorb heat, put black construction paper on the inside on the smaller box. Take flaps from cardboard sheets and cut them as somewhat flared squares. The squares will be attached to the box walls, so the width of each narrow end of the square should be the same as the width of the box side where you're attaching them. The flared ends' width should be a few inches wider compared to the narrow ends' width.
Cover these 4 squares with aluminium foil, so they become ''reflectors''. Position each reflector to the top of each side of the big box. Use glue or staple if needed. Position each reflector up at approximately a 45 degree angle.You can use stick rods that can be glued to the reflectors.
Put the solar cooker in full sun, put food in the smaller box (preferably in a jar or a dark baking pan) and wait for it to cook.
