2. AIM:
To find the most efficient form of house insulation
so that people stop using electric heat pumps
which needs electricity that needs to be made
with fossil fuels which are a finite resource.
3. HYPOTHESIS
My question - Aim:The best form of house
insulation in order to save elictricity. My
hypothesis:
I think that ..black paper would be the best
form of insulation because black [the colour]
absorbs heat so it will stay hotter for longer.
4. research
Insulating your home will save fossil fuel consuming
electricity and provide a healthier and more cosy
family living area. The heat captured from the sun
needs to be stopped from escaping through walls,
ceilings and floors. Insulated surfaces are warmer
than non insulated surfaces. Condensation is less
likely to form in your homes so by insulating your
home you are reducing the likelihood of yucky,
festering mould .which causes illness .
5. MATERIALS
1: (5) Thermometers.
2: (5) Different forms of Insulation.
[Below is the form of insulation I tested
Since I was in a group who tested sponge, pink
bats ,cotton wool and a wooly sock].
Black paper.
6. The Experiment in measured beaker.
1. I placed a thermometer
2. I wrapped the beaker in black paper [my
insulator]
3. I poured hot water from the kettle into the
beaker and measured the start temperature
with the thermometer and recorded it .
4. I set my timer to go in a minute when the alarm
went off I recorded the temperature and
repeated for 15 minutes.
5. I did the same thing with cold water from the
fridge .
6. I did the experiment again with a control to
compare with.
7. Temperatures recorded over 15 minutes

8. APPLICATION
Getting your house insulated is related to our bbi year7
unit sharing the planet because the alternative to
insulation is to buy a big, bulky, expensive heat pump
that needs electricity which in order to be made
people burn finite fossil fuels to make electricity so if
people insulated their houses we wouldn’t have to
burn planet earth’s natural finite resources.

10. CONCLUSION
In the results I compared the black paper
insulation with control and they both in
cold and hot changed temperature at the
same rate so it didn,t make much of a
difference in my test . In the group test the
wooly sock was the best insulator in hot
water and black paper was the worst
insulator that’s exactly the opposite of my
hypothesis!
