Species go extinct every year, but historically the average rate of extinction has been very slow with a few exceptions. The fossil record reveals five uniquely large mass extinction events during which significant events such as asteroid strikes and volcanic eruptions caused widespread extinctions over relatively short periods of time.
Some scientists think we might have entered our sixth mass extinction event driven largely by human activity. Our planet is dependent on an interconnected system. If we lose one species, how does that impact the whole system? What if we lose hundreds?
Help your students understand the gravity of extinction with these classroom resources. The grassland biome is made up of large open areas of grasses. They are maintained by grazing animals and frequent fires. Types of grasslands include savannas and temperate grasslands.

The main steppe vegetation includes herbs and grasses that can grow up to two feet tall and are often referred to as seas of grass. Steppes are often an intermediate area between forests and deserts. Depending on where the steppe environment is in the world, you may see many other types of vegetation, especially in western-leaning steppes. These have more humidity, so you'll see an increased number of shrubs and pseudo-forests of these shrubs.
As such, they are warmer than steppes. They get roughly the same amount of rain as a steppe, but most of it falls during the summer. Savannas get an average of between 15 and 25 inches of rain during this season.
This balance is important because, like steppes, they can become either forests or deserts if the rain pattern shifts. Because they receive so much water, savannas support a few trees, but not enough to obscure the sky from beneath the way a nearby rainforest might. The plants and animals that do live here are highly specialized. One example of adaptations in the savanna are the plants long roots.
These roots reach deep into the soil to extract moisture and water. The most important difference between a steppe and a savanna is where it is located. Savannas lie closer to the equator than steppes and, thus, are warmer than steppes. Being closer to the rainforest means that savannas have two major seasons: a hot, wet summer and a marginally cooler, but much drier winter.
Steppes, by contrast, lie further from the equator and in sheltered areas.
