Good Health and Well-Being, Elementary School Science Projects (86 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' 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.

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

Do-It-Yourself DNA

Science Fair Project Idea

Scientific Method

All living things have DNA inside their cells. How do scientists extract the DNA from cells in order to study it? In this science experiment you can make your own DNA extraction kit from household chemicals and use it to extract DNA from strawberries. Read more

Yeast Reproduction in Sugar Substitutes

Science Fair Project Idea

Scientific Method

There is nothing quite like the smell of fresh-baked bread to make your mouth water! As any baker can tell you, you cannot bake bread without yeast. Yeast actually eat sugar so that they can reproduce and make more yeast, and make bread dough rise. But can they use sugar substitutes to do this? In this science project you will get to investigate how well yeast grow with sugar substitutes as a food source. Pass the butter, please! Read more

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

Blood Clotting to the Rescue: How to Stop Too Much Blood from Flowing

Science Fair Project Idea

Scientific Method

Have you ever had a cut or a bloody nose that seemed like it would bleed forever? Though it might have seemed like a long time, it probably did stop pretty quickly. This is because different factors in a person's blood normally work together to plug the opening caused by the cut in a process called blood clotting or coagulation. However, some people have a genetic disorder called hemophilia that causes them to bleed excessively. If a person has hemophilia, he or she is usually missing some of… 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

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

Comparing the Sweetness of Sugar & Sugar Substitutes

Science Fair Project Idea

Scientific Method

Cake, cookies, pie, ice cream, hot chocolate, lemonade... Yum! What do all these delicious treats have in common? Sugar. In addition to providing sweetness, sugar adds bulk, flavor, and structure to foods. But is it necessary to add sugar to achieve sweetness? Can the same sweetness be achieved using sugar substitutes like artificial or natural sweeteners? In this project, you will test sugar and sugar substitutes and compare the sweetness of each in relation to sugar. In the end, your day will… Read more

How Well Do Disinfectants Work?

Science Fair Project Idea

Scientific Method

Germs are everywhere! We try and clean our home with disinfectants, but do we really get rid of all the germs? Find out with this "hands-on" experiment. Read more

Are There Dangerous Levels of Lead in Local Soil?

Science Fair Project Idea

Scientific Method

The element lead is a neurotoxin that is particularly dangerous to young children. Among other uses, lead compounds were common paint additives until being phased out for safer titanium-based additives beginning in the 1960's. Lead compounds were also added to gasoline to prevent engine knocking, until being phased out beginning in the 1970's. Although paint and gasoline sold today no longer contain lead, soil can have contamination from older sources of lead, such as paint from old buildings.… Read more
