Please follow these revised rules and description. Solar cookers will be judged on event day by information in the revised document.
- Revisions in the document include (but not limited to…please read the document)
- Amount of distilled, room temperature water: 200 ml
- In the spirit of the theme, we encourage teams to use reused and recycled materials
- Teams cannot touch their device/lamp or agitate the water throughout the timed 20 minute challenge. If the solar cooker/lamp needs to be touched during the 20 minute period (i.e. it poses a safety hazard), points will be deducted from your score.
- The exterior of the lamp cover and lamp guard may touch your solar cooker if desired. However, nothing can be within the interior area of the shade and guard, due to safety concerns.
- Your solar cooker must support the lamp throughout the 20 minute competition, and can be placed at your discretion.
- You will be marked on the ingenuity of your design, the reused/recycled materials
- The solar cooker may be no larger than: 0.5 m wide, 0.5 m long and 0.5 m tall. Points will be deducted if the solar cooker exceeds these dimensions.
- For the 20 minute competition, you must use the lamp and bulb provided by the TELUS World of Science on event day.
- Once the 20 minute timed competition is up, the water will be stirred and the temperature will be recorded by a judge. Remember that your design must allow for a temperature probe (23 cm long/ 1 cm wide) to access the water. The bottom of the probe must be submerged in at least 2 cm of water at the time of measuring.
- Judging criteria breakdown has also changed (please refer to document)
Brooder Lamp Specifications are in the document.
One lamp will be displayed at the Front of House, TELUS World of Science, if you would like to view it (it cannot be taken home or used for testing)
