COOL

Step 6
Hypothesis
What do you think will happen? Will the bubble wrap keep the ice cooler or the air? Our Hypothesis was that the bubble wrap will keep it cooler because it traps most of the warm air out of the plastic cup, keeping the ice cooler. Air on the other hand, cannot trap that warm air, therefore allowing the warm air to reach the ice, causing the ice to melt.
Materials
Step 2
Step 4
Take your knife and poke a hole in the middle of both of both of your jar lids. This is so your thermometer can slide through. You can adjust the hole so your thermometer can fit through it.
First, we take two plastic cups and put five ice cubes in each of them. But before this, we have to take the temperature of the ice cubes when they are still in the freezer and record it on your sheet.
Step 3
In one of the jars, put bubble wrap between the cup and the jar. Make sure it is tightly packed and fills in the entire space between the 2 objects. Keep the other just the way it is and leave it untouched in the middle
Step 5
Slide your thermometer through each hole. Take your clay and stuff it around the hole to conceal any gaps between the tip of the thermometer and the lid. Do this to both of your lids.
- 10 ice cubes
- 2 plastic cups
- 2 plastic jars (with lids)
- 2 Thermometers
- Bubble wrap
- Knife
- Clay
- Timer/Stopwatch
- Recording sheet
- Pen/Pencil

Step 1
Place the 2 cups filled with ice into each of the plastic jars.
Put the lids on top of the jars. Make sure that the tip of the thermometer is in the plastic cup so the temperature can be measured. Set your timer/stopwatch to 5 minutes and wait.

Question
Before we came up with a hypothesis, our question was: Which is a better insulator; Air or bubble wrap? We pondered upon this question for a while, until we decided that bubble wrap will work better.
Step 8
Now that you waited 5 minutes, check the temperature of both of the cups of ice and record it into your chart. Which ice was cooler? The jar with the coolest ice is the better insulator.
(Conclusion)
We conducted the experiment, but which one is the better insulator; Air or bubble wrap. If you think it's bubble wrap, you are absolutely correct. There ARE better insulators than bubble wrap, but right now, we are comparing it with air. Bubble wrap blocks most of the warm air from outside from getting to the ice, whereas air does not block it as much. Therefore, our hypothesis was correct, and bubble wrap is indeed a better insulator than air.
Introduction
Don't you just hate it when it's a hot summer day and you decide to put ice in your water bottle. You might not see anything bad about this, but by the time you reach school, the ice is MELTED. What's the point of bringing ice when it's going to melt anyway? You really DON'T want your water bottle looking like this...
Well we've got a solution for all this mess. Let's conduct an experiment to find out which object can keep the ice cool for the longest. No more melted ice! Let's get started!
Science Experiment
AND THE WINNER IS...

Temperature of Ice After 5 minutes in Bubble wrap
-0.2
Temperature of ice After 5 minutes in Air

I know I would hate having to drink warm water at school. But what if this problem happened everyday? What if you didn't know any other way of keeping the ice a little longer than 30 minutes and the water cold until you finished the last drop of water?
Have No Fear!
The Water Bottle Scientists Are Here!
Make your own COOL ICE WATER at home!
KEEP THAT BUBBLE WRAP!
Materials: Bubble wrap, water bottle, ice, water, rubber band/tape
Step 1: Take your water bottle and put ice in it,
to the desired coolness

Step 2: Tighten on the lid of the water bottle and
using a long sheet of bubble wrap, wrap it around tightly.

Step 3: Use tape to secure it in place or a rubber band
