In this interactive resources, students walk step by step through the process of multiplying decimals.

In this video, students learn that, through adaptation, organisms develop certain features that aid their survival. They pass these on to future generations through the process of natural selection.

In this video, students learn that there are two main types of aquatic ecosystems: freshwater and saltwater. The main difference between these two ecosystems is saltiness. Oceans, rivers, swamps, bogs and streams are all aquatic ecosystems.

In this video, students learn that ecosystems are constantly going through gradual changes. Sometimes those changes are natural, and sometimes they are caused by humans.

In this video, students learn each ecosystem is made up of living and non-living things that interact and depend on each other for life. Students learn about producers, consumers and decomposers.

In this video, students learn that the Earth is divided into major kinds of large ecosystems, or biomes. The major difference between biomes in the climate. Several common biomes are explored that include grasslands and forests.
