Life on Land, Fifth Grade Science Projects (46 results)

The United Nations Sustainable Development Goals (UNSDGs) are a blueprint to achieve a better and more sustainable future for all.
These projects explore topics key to Life on Land: Sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss.

Science Buddies' fifth grade science projects are the perfect way for fifth grade students to have fun exploring science, technology, engineering, and math (STEM). Our fifth grade projects are written and tested by scientists and are specifically created for use by students in the fifth grade. Students can choose to follow the science experiment as written or put their own spin on the project.

For a personalized list of science projects, fifth graders can use the Science Buddies Topic Selection Wizard. The wizard asks students to respond to a series of simple statements and then uses their answers to recommend age-appropriate projects that fit their interests.

Let us help you find a science project that fits your interests, with our Topic Selection Wizard.

Use Floating Leaf Disks to Study Photosynthesis
Science Fair Project Idea
Scientific Method
Have you ever seen a (non-carnivorous) plant eat? Probably not! Plants do not get the energy they need from food, but from the sunlight! In a process called photosynthesis, plants convert light energy, water, and carbon dioxide into oxygen and sugar. They can then use the sugar as an energy source to fuel their growth. Scientists have found an easy way to measure the rate of photosynthesis in plants. The procedure is called the floating leaf disk assay. In this plant biology project, you can… Read more
Understanding Wolf Behavior from GPS Tracking Data
Science Fair Project Idea
Scientific Method
If you were leaving home for a long walk, how far would you go? One mile, 5 miles, 10 miles? How about 550 miles?! That's a long way, but some wolves have been known to travel that far when they are leaving their packs in search of a mate so they can form their own pack. But is that how far wolves normally travel? Try this wild wolf tracking science fair project to find out! Read more
How Much Do Different Pet Species Eat Compared to Each Other?
Science Fair Project Idea
Scientific Method
Are you in charge of feeding your family pet? How much food do you think your pet eats compared to other kinds of pets? After adjusting for your pet's body weight, you might be surprised how it will compare to other kinds of pets. What type of pet do you think will eat the most for its body weight? Read more
Butterfly Wings: Using Nature to Learn About Flight
Science Fair Project Idea
Scientific Method
Have you ever seen butterflies fluttering around outside, gliding through the air and landing on flowers? While they are delicate and fragile, butterflies are actually excellent flyers. They are so good, in fact, that scientists at Harvard University studied butterfly wing shapes as an inspiration for building a miniature flying robot. In this science project, you will do your own version of the Harvard scientists' experiment to measure the flight performance of butterfly wings. Read more
Classify Animals with Machine Learning
Science Fair Project Idea
Engineering Design Process
How do you tell the difference between a bird and a fish? Birds tend to have feathers and can fly, while fish have no legs and can breathe underwater. In this project, you will explore how to create a decision tree using machine learning that can classify different animals based on multiple characteristics. This project is designed for beginners and requires little to no coding experience. Ready to give it a shot? Read more
Moss is Boss: Using Plants to Determine Direction
Science Fair Project Idea
Scientific Method
Have you ever gone camping, looked up at the stars, and found the Big Dipper? Two stars in the dipper part of this constellation point to Polaris, the north star, which people have used for thousands of years to help them find their way. In this plant biology science fair project, you'll investigate whether plants, like moss, can help you find your way, too. Read more
What Color Are the Leaves Really Turning?
Science Fair Project Idea
Scientific Method
Everyone loves the beautiful colors of fall, but where do they come from and how does the change in colors happen? In this project, you will uncover the hidden colors of fall by separating plant pigments with paper chromatography. What colors will you see? Read more
How Do Roots Grow When the Direction of Gravity Changes?
Science Fair Project Idea
Scientific Method
You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of gravity) and roots go down (in the same direction as the force of gravity). In this project, you will construct simple devices that hold several germinating seeds, which allow you to watch how growing rootlets respond as you rotate the devices, effectively altering… Read more
Can You Predict a Bird's Lifestyle Based on Its Feet?
Science Fair Project Idea
Scientific Method
Animals survive in all sorts of extreme environments, whether it is a polar bear out and about when it is -40°F, a desert iguana trying to find food as the temperature rises to 110°F, or a deep sea anglerfish living 3281 feet down into the sea. How do they do it? The answer is adaptations! Their bodies have special features that allow them to live in those environments. You might not be able to dive down 3281 feet to observe the deep sea anglerfish, but in this science fair project you… Read more
Does Sense of Touch Impact a Cat's Behavior?
Science Fair Project Idea
Scientific Method
Have you ever seen a cat slowly move its head and whiskers into a small space before crawling through it? They’re using their sense of touch to see if they can fit into the space! In this science experiment, you’ll test how cats use their sense of touch to move through the world by using a maze to determine if they prefer big or small spaces. Read more
