EnergySources and use of energy Measure solar energy in different places Investigate solar panels (number and angle)
Do a survey to find which sources of energy we use to heat our homes. Find out about renewable and non- renewable sources of energy.
Sources and use of energy Measure solar energy in different places Investigate solar panels(size of panel, brightness of bulb and angle from bulb)

Investigating Solar PanelsHow does the size of the panel affect the voltage?
Put the following statements in order -
Collect a solar cell, multimeter and two wires.Measure the voltage on the meter
Do it again with different sizes of solar panelConnect the meter to the solar cell

Investigating Solar PanelsHow does the brightness of the bulb affect the
voltage?
Put the following statements in order -
Collect a solar cell, multimeter and two wires, a power supply two wires and a bulb.
Switch on and measure the voltage on the meterDo it again with the bulb at different brightnessConnect the meter to the solar cell and the bulb

Ways to save money at homeWhat to do ... Why this helps save money.
Only fill the kettle with as much water as you need
Leave hot water in your sink or bath until it cools down.
Do not leave your TV or computer on standby overnight.
Have a shower instead of a bath.
Put lids on saucepans when cooking.
Hang your washing outside to dry instead of using a tumble dryer.
Change light bulbs to energy saving bulbs
Wash clothes at 30oC not 40oC
Ways to save money at homeWhat to do ... Why this helps save money.
Only fill the kettle with as much water as you needIt takes more energy to heat more water.
This costs more.
Leave hot water in your sink or bath until it cools down.
The heat energy in the water helps heat the house. Pouring it down the drain
wastes heat energy.
Do not leave your TV or computer on standby overnight.
Even the little red light on your TV or computer needs energy. This costs money
Have a shower instead of a bath.A bath uses 5 times more hot water than a
shower. Water costs a lot to heat up.
Put lids on saucepans when cooking.If you don’t have a lid, some heat escapes and so more is needed. This costs money.
Hang your washing outside to dry instead of using a tumble dryer.
The sun and the wind are free. A tumble dryer costs money to use.
Change light bulbs to energy saving bulbsEnergy saving bulbs cost less to run and
last longer.
Wash clothes at 30oC not 40oCThe hotter the water, the more it costs to
heat up.
Ways to save money at homeMaking a Survey
•What questions will we ask?•Who will we give the survey to?•How long will we give them to complete it?•What will we do with our results?
EnergyEnergy changers Operate appliances and spot energy changes Build a roller or projectile launcher and investigate. Investigate wind up toys
Find the energy content of different types of food.
EnergyHeat energy Investigate heating solids, liquids and gases Test conductivity of metals Test materials for best insulator
Find out about heat loss from houses and ways to insulate themFind out about times needed to cook foods
