Geology STEM Activities for Kids (15 results)

Geologists study the Earth, trying to understand the forces that gradually shape and change the landscape and ocean floor, as well as forces that make themselves felt more suddenly, like earthquakes and volcanoes. The information geologist discover helps in many ways, from keeping populations safe from disasters like landslides to uncovering important ore deposits like titanium used for surgical equipment.

Scientists study earthquakes so we can understand them better and hopefully one day predict them so we can save thousands of lives. A seismograph is a tool scientists use to record earthquakes and measure their strength. In this activity you will build your own seismograph using simple materials. Read more

Earth is a very watery place! More than 70% of the Earth's surface is covered by water. This is due to the many water bodies that can be found everywhere on our planet. What types of water bodies do you know? They are all very distinct from one another in their appearance, size, shape, and movement. In this activity, you will explore the distinct characteristics of a river by creating a river model inside a pan with sand, pebbles, and real water! After that, you can continue to model other… Read more

Weathering, or the wearing away of rock by exposure to the elements, not only creates perfectly smooth boulders, sinkholes to swim in, and caves to explore; it also eats away statues and buildings. Try it out on a sugar cube and feel how destructive weathering can be. Read more

Have you ever thought about what type of ground buildings are constructed on? Rock, gravel, sand, soil and many others—there are lots of different types of "ground." And this issue becomes especially important in areas that are likely to get earthquakes. In this activity you will build a sweet building on a homemade shake table and find out how an earthquake impacts buildings constructed on landfill. How will your structure perform in a pretend earthquake? Read more

Our planet recycles and reuses everything on it that is needed to support life. It is an amazing, giant recycling system called the biogeochemical cycle. You can actually model this on a small scale by using a plastic bottle and mud to build what is called a Winogradsky column. In this activity, you will build your own Winogradsky columns and investigate how including different nutrients can affect which soil microorganisms flourish and which fail. Read more

You pick up litter, you reduce, reuse and recycle but did you ever consider conserving the soil? It might seem farfetched, but it turns out that soil erosion—or the wearing away of soil by water, wind and other natural forces—is a problem. Productive farmlands can disappear as nutrient-rich topsoil in fields washes away when heavy rains hit them. Waterways can get polluted as pesticides and fertilizers wash into them. Even human life and property are jeopardized, as soil erosion… Read more

Have you ever noticed how much work it is to dig a hole in really hard soil? It's much easier to dig a hole in soft, loose soil. But why is that? Soil that is hard and dry is often compacted, which means that it has been packed down, making it denser and thereby difficult to penetrate. Soil that has become compacted is not only harder for you to dig a hole in, but it can also be much harder for a lot of other organisms, such as helpful earthworms, to survive in. Read more

Have you ever let a map spur your imagination, wondering how life was as a world explorer sailing the oceans in search of new land? Maybe you see yourself drawing a map of your new discoveries. Wait a minute – you just realize Earth is round, so how do you create an accurate flat map? Throughout history, cartographers all around the world have found different methods for creating flat maps of Earth. None can represent reality exactly, but each is useful for specific purposes. Do this… Read more
