Life on Land, Sixth Grade Science Projects (52 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' sixth grade science projects are the perfect way for sixth grade students to have fun exploring science, technology, engineering, and math (STEM). Our sixth grade projects are written and tested by scientists and are specifically created for use by students in the sixth 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, sixth 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.

Predicting Wildfire Intensities and Locations with AI
Science Fair Project Idea
Scientific Method
Have you ever wondered what causes wildfires and how resources are allocated to prevent their spread? In this science project, you will use machine learning to predict areas of wildfire susceptibility and their intensities. Read more
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
Go and Stop? Ant Traffic Signals
Science Fair Project Idea
Scientific Method
Have you ever stopped to watch a trail of ants moving back and forth between a food source and their nest? Have you ever wondered how they establish their trail? You've probably read that ants use chemical signals to communicate with one another. This is a relatively simple experiment that you can do to determine whether ants use attractant signals (positive cues) or repellant signals (negative cues) or both. 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
Exploring the Chemistry of Red Flower Pigments
Science Fair Project Idea
Scientific Method
Are all reds the same? Find out in this science fair project! Investigate if the pigments in one type of red flower are different from those in another type of red flower. Flowers contain an assortment of amazing chemicals that produce color. In this plant biology project, you will analyze the colored pigments in different plants' red flower petals using paper chromatography, and compare the pigments in the different flowers. Read more
Here Today, Gone Tomorrow: Saving Migratory Animals
Science Fair Project Idea
Scientific Method
Extinct might be a word you associate with animals that lived long ago, like the dinosaurs, but did you know that over 18,000 species are classified as "threatened" (susceptible to extinction) today? Scientists involved in wildlife conservation have a tough job; they are in charge of determining what needs to be done to prevent a species from becoming extinct. Habitat, food supply, and impacts of local human populations are just a few of the factors these scientists take into account. It is a… 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
Ask a Cricket, 'What is The Temperature?'
Science Fair Project Idea
Scientific Method
A cricket as a thermometer? Yes, that is right! In this science fair project, you will investigate how the chirps of these tiny creatures can do more than lull you to sleep—they can tell you the temperature! Read more
Plants on the Move! Experiments with Phototropism
Science Fair Project Idea
Scientific Method
Plants move—not very quickly compared to animals, but they do move. Their roots grow downward in response to gravity, and their stems grow upward toward the Sun. In this plant biology science fair project, you will investigate how young plants respond through movement to light. Read more
How Do Cats Respond to Bird Sound Recordings?
Science Fair Project Idea
Scientific Method
Cats are great house pets, but as every cat observer knows, they are also instinctive hunters. This experiment provides an interesting way to learn about cat behavior. You'll play bird call recordings for pet cats, and watch to see if the cat pays attention to the sound (by turning towards it) or ignores it. Will a pet cat distinguish between the calls of local birds vs. non-local birds? Read more
