Join Jessi to find out what a flood is, how they form, and how you can stay safe if there’s a flood where you live!
A flood is when there’s water all over, even where there’s usually land. Floods can be small, and only cover a little space, or they can cover an entire city. Normally, when rain falls, the water can go a few places. The rain can fall into someplace already holding water, like a lake or river, or it can land on the ground, which soaks up the water like a sponge. But have you ever tried pouring water on a sponge for a while? Eventually, the sponge can’t hold any more
water, and it starts to drip. If too much rain falls too quickly, something similar happens with the ground: it becomes completely full of water. The lakes or rivers holding the water can also become too full, and begin to overflow. Sometimes, the floodwater will cover roads, cars, and even buildings.
This video satisfies the 3-ESS2-1, 3-ESS2-2, and 3-ESS3-1 requirements for third-grade science proficiency.
Students who demonstrate understanding can:
3-ESS2-1. Represent data in tables and graphical displays to describe typical weather conditions expected during a particular season.
3-ESS2-2. Obtain and combine information to describe climates in different regions of the world.
3-ESS3-1. Make a claim about the merit of a design solution that reduces the impacts of a weather-related hazard.
