The lunchroom at Sunset Elementary School floods each year. When there is more than one inch of water on the ground outside, water flows under the doors and into the building. Dr. Rogers, the principal, wants to find a way to protect the lunchroom from flooding. Select 3 times the lunchroom is most likely to flood.

4.

The lunchroom at Sunset school is near a river. When it rains a lot, the river gets full and overflows. The extra river water flows toward the lunchroom. The water collects around the lunchroom doors. If the water is more than one inch deep, it can get into the lunchroom through the spaces around the doors. There are many ways to solve this flooding problem. Which of the following actions would help keep the lunchroom from flooding? Select all that apply.

The strong wind of a hurricane blows on the outside of a house. If the wind is strong enough, it can blow the roof off or blow the walls over. If a window or door breaks during a hurricane, the strong wind blows inside the house, too. The wind can damage the roof and the walls of the house and any objects inside. If any people are in the house, they could get hurt. Rainfall is another issue with hurricanes. Hurricanes can bring large amounts of rainfall and can cause storm surges too that can flood an area. How can people protect the insides of their homes from the strong wind and water of a hurricane? Choose all that apply.

15.

There are many ways to solve the flooding problem in the lunchroom. But not all of them will work for Sunset School. To choose the best solution, the school must think about the constraints of the problem. A constraint is something that holds you back from taking a certain action. For example, cost can be a constraint. If something costs more money than you have, you won't be able to buy it right away. Several parents and teachers form a planning team to help solve the flooding problem. The team receives the following letter from the principal: To the Planning Team: Thank you for working with me to solve the flooding problem at our school. As you think of ideas to solve this problem, please keep these two constraints in mind: We cannot build any new buildings. That would cost too much money. It would also take too long. We can make changes only to our school. We are not allowed to make changes to other parts of the city, including the area next to the river. Sincerely, Dr. Rogers Based on these constraints, what can the school do to solve the flooding problem?

a)

Build a new lunchroom uphill from the river to keep water from reaching the lunchroom

b)

Build a wall along the river to keep the river from overflowing

c)

Block the lunchroom doors to stop water from getting in.

16.

Robin's class researched tsunamis (huge tidal waves). They learned about different ways people and towns protect themselves from tsunamis. Some of these ways are: building a seawall to protect the town in case a tsunami comes, moving everyone to high ground when a tsunami is coming, moving people into deep water in boats when a tsunami is coming. These last two work best in places that teach the people what to do if a tsunami is coming. How can Robbin's class best compare these solutions to learn which one saves the most lives?

a)

Research how well each solution worked in the past.

b)

Try each solution in a real tsunami and observe the results.

c)

Improve each solution using engineering design.

d)

Test whether it takes longer to get to high ground or to deep water.
