Are We Ready?

In Room 14 we are investigating if we are ready for an emergency, that would mean we would have to stay at school over night.
Firstly we got into groups and discussed what was essential and what wasnt. We came up with four things.
Food
First Aid Kits
Toilets/toilet paper
Water

Food
We looked around the school for food. We found the freezer. We counted 4 loaves of bread with 20 slices in each. That means there were 80 slices of bread. This is not enough to feed the whole school.

First Aid Kits
There are 3 big First Aid Kits in the school. They are all in the office. We do not have access to these if we are in a lockdown.

Toilets
There are 400 sheets in each toilet roll. There are 350 rolls of toilet paper stored in the school. This is enough to cater for the whole school.

Water
We went searching around the school and we found a pile of boxes. 6 across and 4 high. This means there are 24 boxes.
We opened the boxes and saw there were 4 bottles down and 6 bottles across. So 24 bottles in each box.

We needed the total amount of bottles. So we needed to add 24 boxes of 24 bottles.
We used a lot of different strategies.
Doubles
Multiplication facts
Rounding
Partitioning
There were 576 bottles

There are 468 students
45 staff
That totals 513

That means there is enough water for 1 bottle per person with 63 left over.

On the side of the box we discovered a sign that said 'Expires Feb 2013'
We didnt think we were able to drink this water so we researched if we could. It turns out we can. It may not taste as good but it is still okay to drink.
We think we have enough water to last one night.

We emailled Mr Bremer and invited him to discuss the situation.

Mr Bremer came into our class to discuss the situation. 

As a class we thought there should be 1 first aid kit between 2 classes.

Firstly he discussed first aid kits

Mr Bremer disagreed that we need more, he thinks 3 is enough.

Secondly we discussed the food situation. We thought each child should bring a lunchbox with dried or canned food that was named and stored in the classroom. This would be sent home at the end of the year if not used.

Mr Bremer thought this was not necessary because we have a lot of milk in the school. Some of us were concerned about the people who can not have milk. Mr Bremer said "they would have to have water".

These choices are based on the fact that our school is placed right next to the Civil Defence Headquarters.
