The effects a flood has on the environment
Look at the following glogster.. Watch the videos. Think about what the possible effects that this type of event has on the environment? Look at the background of the videos.
Before you watch the video, predict what you think you will see. What effects you already know floods have.
Next observe the video. What did you see? What effects did the flood have on the environment?
Then evaluate your findings. How did this make you feel? What have you learnt so far? Reflect.
I would like to see this in your blogs.

What about the positive effects a flood can have on the environment?
In many natural systems, floods play an important role in maintaining key ecosystem functions and biodiversity. They link the river with the land surrounding it, recharge groundwater systems, fill wetlands, increase the connectivity between aquatic habitats, and move both sediment and nutrients around the landscape, and into the marine environment. For many species, floods trigger breeding events, migration, and dispersal. These natural systems are resilient to the effects of all but the largest floods.
The environmental benefits of flooding can also help the economy through things such as increased fish production, recharge of groundwater resources, and maintenance of recreational environments.
