Elementary School Geology Science Projects (9 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. Browse through our list of geology science and engineering projects and you may be surprised by all the things geologists work on.

Fantastic Fossilization! Discover the Conditions For Creating the Best Cast Fossils
Science Fair Project Idea
Have you ever stood close to a fossilized T. rex skull and counted its razor-sharp teeth? Or, have you seen a fossilized stegosaurus skeleton and thought about how it defended itself with tail spikes and armored plates? A trip to a natural history museum lets you imagine what dinosaurs looked like and wonder what life with them on Earth was like. Fossils give us information about animals and plants that lived long ago. Certain places around the world contain more fossils than others. Why?… Read more

Jumping For Geodes: Can You Tell the Inside from the Outside?
Science Fair Project Idea
Have you ever heard the expression, "You can't judge a book by its cover"? What do you think that means? That a book with a very plain cover might have a very exciting and interesting story inside? Well, in this geology science project, you'll see if the same expression holds true for a rock, but not just any old rock, a special type of rock called a geode, which looks rather plain and ordinary on the outside, but inside can hold crystals and beautiful colors! You'll discover if the texture or… Read more

Soil Compaction
Science Fair Project Idea
Have you ever had to dig a hole in really hard soil? It is a lot of work! In this science project you can make an instrument to test the soil and find out how compacted it is, before you dig! Read more

Porosity and Particle Size
Science Fair Project Idea
Often, when we think of something that is solid we think about rocks. But in reality, rocks have tiny holes of air inside them. This is called porosity. In this science project you can find out what it means to be "solid as a rock!" Read more

Go with the Flow: Model Rivers with Cornmeal, Sand, & Water
Science Fair Project Idea
Have you ever had fun playing with sand and water, observing how little rivers you create carve their way down to the lowest point of the sandbox, backyard or beach? Some meander, others braid, and some carve a path straight down. Hyrdologists (or scientists who study water) do very much the same thing! Only they set up the model in a particular way, so observing their mini-rivers helps them answer questions about how water flow affects the environment. In this geology science project, you… Read more

Rocky Secrets: Where Does Oil Hide?
Science Fair Project Idea
You may have heard the expression, "You can't get blood from a stone." But what about oil? Can you get petroleum oil from a stone? In this geology science fair project, you'll find out what kinds of stones make the best storage rocks for oil. You'll see which ones can soak up oil like a sponge, and which ones cannot soak up oil or let it pass through, but can act as a "cap" to contain the oil in secret underground traps. Can a hard rock really act like a soft sponge... maybe SpongeBob… Read more

Soil Color and Moisture
Science Fair Project Idea
Have you ever taken a step onto what appeared to be dry ground, only to find yourself ankle-deep in mud? Yuck! When you walk through damp soil, it can be a very messy experience. How can you tell if soil is wet or dry before you step on it? In this science project, you will investigate whether the color of the soil can help you determine how dry or wet it is. Read more

Now You See It, Now You Don't! How Acidic Waters Make Rocks Disappear
Science Fair Project Idea
If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more

Sorting Out Sedimentation
Science Fair Project Idea
Sedimentary rock forms in layers that are deposited one after the other over long periods of time. Oftentimes, sedimentary rock contains fossils and other debris that are deposited within the layers. How do sediments form? How are sediments of different shapes, sizes, and types sorted during the process of sedimentation? Find out in this science fair project! Read more
