Good Health and Well-Being, Fourth Grade Science Projects (38 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 Good Health and Well-Being: Ensure healthy lives and promote well-being for all at all ages.

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

Fighting the Flu: How Your Immune System Uses Its Memory
Science Fair Project Idea
Scientific Method
Being sick is no fun, especially when your friends are doing exciting activities that you have to miss out on. Thankfully, common illnesses usually last for just a few days, and then you start to feel better. Why is this? It is thanks to the immune system, which is a group of special organs and cells in your body that constantly work to keep you healthy. In this science project, you will make a simple model to investigate how the immune system defends the human body from common illnesses, and… Read more
Why Aren't All Medicines Pills?
Science Fair Project Idea
Scientific Method
No one likes shots, so why don't we swallow all our medications? In this science project, you will use a model to explore one challenge behind making medications we can quickly swallow, using insulin (a medication taken by some diabetes patients) as an example. Will your medication be functional after spending time in an environment similar to the stomach? Read more
Is Plant-Based Milk as Protein-Packed as Dairy Milk?
Science Fair Project Idea
Scientific Method
What kind of milk do you drink in your household? Do you drink 2% dairy milk, whole dairy milk, or plant-based milk like almond milk or soy milk? Have you ever considered why you drink it? As more sustainable and alternative food options become increasingly available, people are interested in the nutritional value of plant-based foods. The US government dietary guidelines state that dairy milk is a good source of protein. Are plant-based milk sources also a good source of protein? In this… Read more
Wearable Limp Detection Device
Science Fair Project Idea
Engineering Design Process
Have you (or anyone you know) ever sprained an ankle or broken a leg? It might have taken some practice to walk again after recovering from an injury. Some people might even need to work with a physical therapist. In this project you will program a wearable device to recognize when someone is limping instead of walking normally.  Read more
Motor Imagery Visualization's Impact on Fine Motor Skills for Space Flight
Science Fair Project Idea
Scientific Method
In this science experiment, you will model and test how visualization of a task can change the accuracy of your fine motor skill performance. You will use the small muscles in your hands to model how your body would perform on Earth versus a space launch. Read more
Liver Stinks!
Science Fair Project Idea
Scientific Method
Sometimes science can be really messy or use pretty disgusting ingredients. That is what it takes to understand how the world works, even if the experiment isn't pretty. Do you like chemical reactions that stink and ooze foamy bubbles? Do you think it sounds fun to make a super gross liver smoothie? Then this is the experiment for you! Read more
How Are Antibodies Used for Blood Typing?
Science Fair Project Idea
Scientific Method
Have you ever heard about different blood types? Do you know what your blood type is? Antibodies help scientists determine different human blood types. This project is a practical introduction to the human immune system in which you will learn about what antibodies are, how they are formed, and how they can be used to identify different types of cells.

No Pain, Lots of Game
Science Fair Project Idea
Scientific Method
You might have heard the expression, "Take two aspirin, and call me in the morning." What if instead a doctor said, "Play two video games and call me in the morning"? Would you be shocked? Or think it was time for a new doctor? In this science fair project, you'll investigate whether video games, and other forms of mental distraction, have the power to relieve pain. Read more
Modeling the Chances of Getting an Autoimmune Disease
Science Fair Project Idea
Scientific Method
Do you know someone who has an autoimmune disease? Autoimmune diseases are fairly common, affecting more than 23.5 million people in the United States, which is about 1 in 13 people! You may have heard of some of them, such as diabetes (type 1), rheumatoid arthritis, and celiac disease. Many autoimmune diseases are poorly understood, but they all have one thing in common: they happen because a person's immune system (which normally fights off germs to keep the person healthy) attacks the… Read more
Molecular Scissors
Science Fair Project Idea
Scientific Method
Ever used a pair of molecular scissors? Restriction enzymes are molecular scissors that cut DNA into pieces. Find out which enzymes will cut, and where by making a restriction map. Then you can figure out what will happen if you change the sequence of the DNA. Will the same enzymes still cut the new DNA sequence? Read more
