Science 4: Earth's Spheres

Sabrina talks about two of the four spheres that make up our planet; The Geosphere and the Biosphere. What's in these spheres? How do they affect us?

In this episode, Sabrina talks about the Hydrosphere and the Atmosphere and what is contained in each one.

We've already talked about how the Earth is divided into four spheres (The Hydrosphere, the Biosphere, the Geosphere, and the Atmosphere). But, how do these different spheres interact with each other?

Sabrina gives us a real-world example of how the Hydrosphere and Geosphere affect each other in the form of Weathering and Erosion.

So... what makes the wind? You might be surprised to learn that it has to do with two of Earth's spheres: the hydrosphere and the geosphere.

In this episode, Sabrina chats about how things like mountains, volcanoes, and plateaus come into being.

Water travels... a lot. In fact, the water cycle is amazing and takes water all over the planet by using evaporation, condensation, and precipitation.

Today we continue our exploration of the water cycle by drinking some dinosaur pee. Yum!!

What are the differences between weather and climate? Learn why it's important to understand both weather and climate.

What's the difference between weather and severe weather? Is it just how hard the wind is blowing? Let's find out!

Today we're going to take a hike up Mt. Kilimanjaro so we can talk about how the geosphere changes based on many different things.

Today we're going down down down into the ocean to see what habitats await us there. We'll see how the hydrosphere affects the biosphere!

Check out this slide show about the three major layers that make up our Earth and the living conditions and resources that we have. There's a quiz after the slide show.

Play this animated video to learn more about the atmosphere - including all of the different layers of gases. There is also a quiz to test yourself.

Did you know that all living things change their environments? Humans change our environments in big, obvious ways. Learn more about it with Sabrina

We've talked about humans changing their environments, but all animals change their environments just by living in them

The world changes. Sometimes it changes so slowly that we don't notice it, but other times it changes REALLY FAST! Sabrina talks about some of the reasons things can change quickly or slowly.

We Indigenous people understand that we have responsibilities to foster balanced relations with those who share themselves so that we might maintain our health. Download our food arc to use with your students
