Zero Hunger, Elementary School Science Projects (31 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 Zero Hunger: End hunger, achieve food security and improved nutrition and promote sustainable agriculture.

Science Buddies' elementary school science projects are the perfect way for elementary school students to have fun exploring science, technology, engineering, and math (STEM). Our elementary school projects are written and tested by scientists and are specifically created for use by students in the elementary school grades. 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, elementary schoolers 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.

Can Every Part of a Plant Regrow?
Science Fair Project Idea
Scientific Method
Have you ever picked a flower and tried to make it stay alive in a cup of water? How long does that last? Do some flowers last longer than others? Why do you think that is? In this experiment, you will compare different plants to see which ones can regrow or regenerate after damage and learn why some plants are better at it than others.  Read more
Sprouting Sweet Potatoes Slips
Science Fair Project Idea
Scientific Method
Have you ever enjoyed eating a tasty sweet potato? They can be served as yummy mashed sweet potatoes with melted butter, turned into golden-brown sweet potato fries, or prepared in many other scrumptious ways. Did you know that you can make a sweet potato grow into a sweet potato plant, and grow several sweet potatoes this way? In this science project, you will grow your own sweet potato plants and investigate what part of the sweet potatoes is needed to grow the plants. Read more
Build a Circuit to Automatically Water Your Plants
Science Fair Project Idea
Engineering Design Process
Have you ever taken care of a plant? It can be tricky to get it right. You have to remember to water it regularly, and you also have to make sure to give it the right amount of water — not too much or too little. What if technology could help? In this engineering project, you will learn how to automate the entire process of watering a plant. Using a soil moisture sensor and a pump, you will build a circuit that will automatically detect when the soil is too dry, add water, and stop when… Read more
Hydroponics: Gardening Without Soil
Science Fair Project Idea
Scientific Method
What do plants need to grow? Most of us would answer that they need light, air, water, and soil. But by using a process called hydroponics, you can grow plants without soil! How does it work? Try this project and see for yourself! Read more
Green Technology: Build an Electronic Soil Moisture Sensor to Conserve Water
Science Fair Project Idea
Engineering Design Process
Water is a valuable resource, and water shortages are a serious problem in many parts of the world. The problem can be made worse by people who waste water; for example, by watering a garden or using sprinklers on their lawn (or a farmer taking care of an entire field) when it has rained recently or the soil is already moist. How can you help conserve water and prevent such waste? One way is to build an electronic soil moisture sensor. This project will show you how to build a circuit that… Read more
Can Plants Stop Soil Erosion?
Science Fair Project Idea
Scientific Method
Soil erosion can cost the world billions of dollars every year by washing pollutants into our streams and rivers and by causing the loss of farmland. What can you do about this problem? Help save the world (and some money!) with nothing more than a few plants! Read more
An Experiment on Nitrogen Fertilizers
Science Fair Project Idea
Scientific Method
Plants need nitrogen to grow healthy stems and leaves. Although nitrogen is the most abundant element in the air we breathe, that form of nitrogen cannot be used by plants. Nitrogen contained in fertilizer, on the other hand, is readily taken up by plants. In this experiment, you will compare plants grown without nitrogen fertilizer to plants grown with nitrogen fertilizer. Read more
How Do Food Preservatives Affect the Growth of Microorganisms?
Science Fair Project Idea
Scientific Method
This project uses liquid cultures and agar plates to investigate the effects of different concentrations of a food preservative on microbial growth. Read more
Dust Busters: How No-Plow Farmers Try to Save Our Soil
Science Fair Project Idea
Scientific Method
Do you have any great-grandparents who lived through the Great Depression in the United States during the 1930's? If so, they might have stories to tell about terrible dust storms that blackened the skies, from the Midwest to the east coast. Severe drought was a factor in causing this "Dust Bowl" era, but decades of poor farming practices contributed to it, too. In this environmental science fair project, you'll learn about farming methods that help keep dirt from drying up into dust, and help… Read more
How Does Soil Affect the pH of Water?
Science Fair Project Idea
Scientific Method
Did you know that soils can be alkaline, neutral, or acidic? Most plants grow best in soil near neutral pH, but some plants prefer slightly acidic and others slightly alkaline soil. What is the pH of the soil in your garden? What happens to the pH of water that comes in contact with soil? In this science project you will get to find out. Read more
