3rd Grade Science : Reduction of Weather-Related Hazards

Example Questions

Example Question #1 : Reduction Of Weather Related Hazards

Sharon and Mike are building a new home on a piece of land they just bought. It is located next to a large river in an area that floods several times a year. The flooding is caused by heavy rain or melting snow upstream. When the floodwaters rise, the owners are unable to enter the home. They have come home and had to walk through water to get into the house. If the water enters the house, it damages not only their things but the structure of the house, and it all must be replaced.

What is the weather-related hazard that Sharon and Mike face?

Earthquakes

Mudslides

Flooding

Flooding

Explanation:

Sharon and Mike are in a tough situation because of flooding. This weather-related hazard can happen very quickly and cause severe damage to property and even injuries or casualties. As the river overflows, the water runs into the nearby communities, and homeowners are at risk of losing everything.

Example Question #2 : Reduction Of Weather Related Hazards

Sharon and Mike are building a new home on a piece of land they just bought. It is located next to a large river in an area that floods several times a year. The flooding is caused by heavy rain or melting snow upstream. When the floodwaters rise, the owners are unable to enter the home. They have come home and had to walk through water to get into the house. If the water enters the house, it damages not only their things but the structure of the house, and it all must be replaced.

Sharon and Mike don’t want to move somewhere else. They hire a team of builders and give them the following requests: the house must remain safe and dry, they want to be able to enter if the water is high, and they want to be able to see the river from their home.

Which solution would meet their criteria?

There is no solution, Sharon and Mike must move.

Build the house further inland, so there is less flooding

Build a third floor to the house

Build the house on stilts

Build the house on stilts

Explanation:

The criteria that Sharon and Mike set was specific ad needs to be followed when designing a solution. Moving the house further inland or not building at all are two solutions that do not meet the criteria. Making a third level would help with the views and keeping them on the property, but it would not address the flooding. Building the house on stilts would be a solution that meets all of their needs.

Example Question #1 : Make A Claim About A Solution To Reduce Impacts Of Weather

Albert's class is working on a project to reduce the impacts of weather on a house. They each have to build their home, and it has to withstand a flood. Students design solutions that will help reduce the damage to the house.

Which solution is the most reasonable to reduce damage to the house?

Build a barrier around the home to stop the water

Instead of a one-story house, build a two-story house

Dig large holes all around the house the catch water

Build curved walls, so the water rolls off the house

Build a barrier around the home to stop the water

Explanation:

The most reasonable solution that was presented is to build a barrier around the home to stop the water. Curved walls are not practical, making a second-story may keep things dry on that level, but the first-floor and base of the structure would still be damaged, and late holes in the ground are not reasonable.

Example Question #1 : Reduction Of Weather Related Hazards

Ami's teacher has challenged the class to build a structure that can withstand an earthquake simulation. The teacher is going to shake the structure for 20 seconds and see which is still standing afterward. The groups are arguing about which part of the building should be the strongest.

Which group's solution is most likely to withstand the earthquake simulation?

Group 3: This group focuses on the foundation of the building. They believe if the base of the home is strong the remainder of the building will be too.

Group 1: This group focuses on a sturdy roof. They do not want high winds or the shaking to damage the roof.

Group 2: This group is focused on strong walls. They believe that if the walls are strong there will be less damage to the entire house.

Group 4: This group is focused on landscaping. They believe if the tree roots are healthy, they will hold the soil together and stop the earthquake.

Group 3: This group focuses on the foundation of the building. They believe if the base of the home is strong the remainder of the building will be too.

Explanation:

Earthquakes are a significant weather-related hazard that are difficult to predict.  Buildings in earthquake-prone areas must be constructed with stability in mind. All parts of the house are important and need to be built with high quality, but "Group 3" is focused on the foundation, which is critical. If the base of the building is strong and stable, there is less of a chance that the rest of the building will fall.

Example Question #1 : Reduction Of Weather Related Hazards

Which of the following answer choices is a weather-related hazard?

Flooding

Lightning

All answer choices are weather-related hazards.

Hurricanes

All answer choices are weather-related hazards.

Explanation:

Weather-related hazards are numerous. Hurricanes, lightning, tornadoes, flooding, and mudslides are just a few. They can be dangerous and deadly to Earth, people, and property.

Example Question #6 : Reduction Of Weather Related Hazards

Sharon and Mike are building a new home on a piece of land they just bought. It is located next to a large river in an area that floods several times a year. The flooding is caused by heavy rain or melting snow upstream. When the floodwaters rise, the owners are unable to enter the home. They have come home and had to walk through water to get into the house. If the water enters the house, it damages not only their things but the structure of the house, and it all must be replaced.

What type of weather-related hazard could increase the likelihood of flooding?

A hurricane

None of the answer choices are correct

All of the answer choices are correct

A wildfire

A duststorm

A hurricane

Explanation:

Sharon and Mike are in a tough situation because of flooding. This weather-related hazard can happen very quickly and cause severe damage to property and even injuries or casualties. As the river overflows, the water runs into the nearby communities, and homeowners are at risk of losing everything.

Experiencing a hurricane would increase the likelihood of flooding due to the massive amounts of rain the storms can bring to an area. A typical hurricane brings six to twelve inches of rain, and this could be very dangerous for areas prone to flooding.

Example Question #7 : Reduction Of Weather Related Hazards

Albert's class is working on a project to reduce the impacts of weather on a house. They each have to build their home, and it has to withstand a tornado. Students design solutions that will help reduce the damage to the house.

Which solution is the most reasonable to reduce damage to the house?

Strengthen windows and doors

Make repairs to roofs before tornado season

All of the answer choices are correct

Install strong garage doors

None of the answer choices are correct

All of the answer choices are correct

Explanation:

Tornados are very destructive weather-related hazards. Their impacts on homes and lives can cause significant problems, damage, and even death. It can be hard to predict tornadoes, so preparation beforehand is essential, especially if one lives in an area prone to frequent storms. Strengthening windows and doors, as well as garage doors, can help create a more reliable barrier against high winds and the pressure that is created during a storm. If there is existing damage to roofs, it is best to repair it before storm season to create a strong structure and reduce the chance of further destruction.

Example Question #2 : Reduction Of Weather Related Hazards

Kaci's teacher has challenged the class to build a structure that can withstand a(n) _____________ simulation. The teacher is going to blow a fan towards it at high speeds. The structure is on a spinning platform, and students will spin it for about ten minutes.

What type of weather hazard is being described?

hurricane

flood

wildfire

Explanation:

In the description of Kaci's weather simulation, the class is being asked to create a structure that can withstand a tornado simulation. High winds that move in a circular pattern are characteristic of a tornado. Hurricanes and flooding require large amounts of water, and no water is mentioned in the question. A wildfire would not fit the description of the simulation.

Example Question #9 : Reduction Of Weather Related Hazards

Which of the following answer choices is NOT a reasonable solution to reduce the impact of wildfires?

Raking up dead leaves and brush from forest floors

All of the answer choices are correct

Fine people who throw cigarettes out of car windows

None of the answer choices are correct

Controlled burns to clear out debris

None of the answer choices are correct

Explanation:

Wildfires destroy millions of acres of forest each year across the globe. There are many reasonable solutions to help reduce the damage and devastation. Firefighters can hold controlled burns in areas with dry, aged debris that is likely to spark and catch fire. Raking up dead leaves and brush from the forest floor can help remove the kindling that causes many wildfires. Many fires are started accidentally by people throwing cigarette butts out their car windows. If there were fines in place for these behaviors, it might reduce the number of fires started. All of the answer choices are reasonable solutions.

Example Question #10 : Reduction Of Weather Related Hazards

Severe weather can have negative impacts on the people and communities it passes through. Anaya's class is trying to come up with a solution to reduce that impact from hurricanes. They decide that replacing regular windows with windows that are more resistant to strong-winds and impact-proof would be an excellent way to minimize damage and injuries during the storm. Each student has to give their thoughts about the solution.

Which student's claim below is a reasonable explanation of why strong-wind resistant and impact-proof windows would help?

Anaya - "I agree with replacing windows to reduce danger and injuries. Hurricanes have high winds, and strengthening the windows will protect families from debris and damage."

There is no way to tell if this is a good idea or not.

Robby - "I agree with the solution to replace the windows. I think that hurricanes rain a lot, so new windows would help keep the house dry."

Sadie - "I agree with replacing windows to reduce danger and injuries. People are scared of hurricanes, so new windows will give them a better view of the storm."
