Pet House
Hypothesis:
I think the pet house will be waterproof because I covered every part I could see and I think
my house won’t be warm enough because it did not feel that warm when I finished it.
Aim:
To make the pet house waterproof and warm so it can melt butter quicker than butter
outside and so water won’t get inside the pet house.
Apparatus:
1 cardboard box
2 big and 1 small piece of bubble wrap
1 long strip of aluminium foil
1 long strip of glad wrap
Extra cardboard
Coloured paper (optional)
White paper
Scissors
Ruler
2 coloured pencils and grey lead pencil
Stanley knife
Sticky tape
PVA glue
Watering can (for testing)
Stick of butter (for testing)
Method:
Step 1: Collect all materials and get a cardboard box which is 30cm by 20cm.
Step 2: Cut off all the flaps except for one of the top flaps.
Step 3: To cut the windows cut 2 7cm squares on the sides in the middle of the house.

Step 4: To create the roof, cut out a piece of cardboard exactly the same size as the top of
the house then cut in half and make a triangle and place it on top, then stick it with sticky
tape on the sides.
Step 5: To make the roof waterproof, cut about 25cm of foil
and stick it on the roof, if there are any unwater proof spaces,
then cut a bit of foil and cover them.
Step 6: To make the walls waterproof, get little bits at a time
of glad rap and stick it all on the walls. Make sure you cover
every part of the house so it is waterproof.
Step 7: Once that is done, put sticky tape on every edge that you see from top to bottom
except for the window edges.
Step 8: For the windows, get a bunch of sticky tape and cut it 9cm-11cm long and stick it on
the sides of the window in and out. You may need more stick tape.
Step 9: To make the insulation, cut 2 pieces of card board exactly the same size as the sides,
then make sure they fit in and measure out the windows by tracing them out, then get 60cm
by 30cm square of bubble wrap, fold it until you 4 layers and stick it and trim the edges even
where the windows will be. If you want extra insulation, then repeat where it says “then get
60cm by 30cm……………”
Step 10: To hold up the flap, get 2 8cm by 1cm pieces of cardboard. Wrap them both up
with foil, and then try to stick it under on the side with sticky tape.
Step 11: For the back insulation, cut a 20cm by 15cm piece of cardboard then get a 50cm by
30cm piece of bubble wrap. Fold it into 4 layers and stick it. Trim the edges. Again if you
want extra insulation, then repeat where it says “50cm by……………”
Step 12: To stick the insulation, put lots of glue on the sides then stick it bubble wrap first
then put lots of glue at the back and do the same thing as with the side insulation.
Step 13: To make the inside have colour, chose a colour and get 4 pieces of paper of the
colour you choses. After that then measure all of the paper out for the sides, roof and back
of the house, even the windows. (This may be hard). Then stick the measured paper of each
on the sides, then the roof and then the back of the house.
Step 14: For the floor, measure out a piece of carpet witch is 29cm by 19cm. Then stick it
inside on the floor.
Step 15: This part is optional. To make a name for the top, cut a piece of cardboard witch is
5cm by 11 1/2cm. Wrap it in foil and cut a piece of paper small enough and write whatever
you want on it then use sticky tape and stick it in the middle. Place it on top of the flap.

Step 16: To make a doorway, cut a piece of cardboard exactly the same size as the front of
the house then cut a small doorway. Then stick a coloured paper of your chose over it and
you may get a piece of paper and stick it on the side with a number on it.
Step 17: Stick any other edges with sticky tape.
Step 18: Test it to see if it is waterproof and warm inside and
check if you’re pet fits in the pet house.
Results
When I poured the water over my house, the water couldn’t soak in the roof and the walls
of the pet house. My house was waterproof on the roof and the walls of the house. A little
bit of water got inside the house because the door was open but it was still waterproof. We
used 6 litres of water. We all left the butter in our houses for 1 day and about 3 hours.
Unfortunately the butter did not melt even tho it was still warm inside. It was only a bit soft.

Conclusion
The house that was most waterproof was Lachlan’s house because he had no water inside.
The evidence we have to prove we made a waterproof house so no water would get inside
the house. The house that was most insulating was mine because I put a lot of bubble wrap
on the sides and the back of the house. The evidence we have of this is making the house
warm for a pet. Some good house design features of our houses were colourful walls, soft
carpet, strong roof and strong walls. Some areas I could have improved to make my house
more waterproof would be to put more waterproof materials on the house, make sure the
corners are waterproof and make sure every tiny part of the house is waterproof. Some
areas I could have improved to make my house more insulating would be to put bubble
wrap on the ceiling of the house.
