3rd Grade Science › Explain how animals may change due to environmental changes
Environmental changes cannot cause problems for animals.
Polar bears hunt seals through holes in the sea ice. They travel from great distances across sheets of frozen water to find seal colonies. The seals rest on the ice in large groups and raise their pups. When the seals go out to hunt fish they slip into the water from the edge of the ice.
If temperatures rise and the ice begins to melt, what impact could there be for the seals?
Which answer choice is an example of a change that an animal would NOT be able to make due to the environment changing?
Environmental changes will only affect animals if they make temperatures warmer.
Birds that are migrating to California usually stop along the way to rest, eat, and drink water. The birds head to California to get away from the frigid weather in Canada. They would not survive without migrating. This year as the birds land at their usual stopping points, they notice it is hotter and dryer than average. As humans, we realize we are in a drought, but the birds do not know this. They are struggling to make the rest of the journey because it is too hot, and there is no water to drink.
What will most likely happen to the birds because of the severe drought?
What is a positive effect that an environmental change may have on an animal?
What does the term environmental change mean?
