A group of students has designed a solar cookerfor an investigation. They are investigating

whether the material that a container is made ofhas an effect on the rate of temperature change

over time. They obtain three containers ofidentical size. They add water to each container.The containers are placed inside the solar cooker,which is made of a box lined with aluminum foil.

a) Identify two additional pieces of equipment that thestudents will need to use in their investigation.

b) Explain why each piece of equipment is necessary.

Possible Correct Responses:• Graduated cylinder: to measure the water that must

be added to the containers.

• Three identical thermometers: to be suspended in the containers so that water temperature can be measured.

• Timing device: to make sure the data for each container are collected within the same increments of time.

• Safety equipment: glove or cloth pad to handle the containers safely after heating or safety glasses to protect eyes from hot water that could splash.

• Lamp/light source/solar heat: to heat up the solar cooker.

• Meter stick: to measure the same level of water for each container.
