Responsible Consumption and Production, Third Grade Science Projects (18 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 Responsible Consumption and Production: Ensure sustainable consumption and production patterns.

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

"Plastic made from milk" —that certainly sounds like something made-up. If you agree, you may be surprised to learn that in the early 20th century, milk was used to make many different plastic ornaments —including jewelry for Queen Mary of England! In this chemistry science project, you can figure out the best recipe to make your own milk plastic (usually called casein plastic) and use it to make beads, ornaments, or other items. Read more

Do your parents ever get upset with you for "wasting" paper and ink from your printer? Maybe you wanted to print a comic you found online, or a whole bunch of pictures of you and your friends being goofy, or all the instructions on how to put together that really awesome LEGO® castle. But 20 pages of text and pictures later, your mom or dad is yelling at you. Why do they even care how much you print? And why do people say it is a "waste" of paper? Try this printer-saving science project to… Read more

Scientific Method
Fresh whipped cream is the final touch for many delectable desserts. One issue with fresh whipped cream is that it has to be used soon after it is made, especially if it is at room temperature, or it starts to collapse into goo. This is a problem for its use in frostings or inside pastries as filler. Whipped cream can be stabilized by adding unflavored gelatin. Stabilized whipped cream can be used at room temperature and it has a much longer life. But how much gelatin is just right? Try… Read more

Have you ever dreamed of a world where you could take the scraps from last night's dinner and toss them into your car's fuel tank and make gas? Well, we're not quite in "Back to the Future" yet, but in this energy science fair project, you'll discover that food scraps, dead plants, sawdust, and other decaying organic matter, called biomass are a rich source of energy. You can get energy out of biomass by burning it, turning it into a liquid, or by turning it into a gas called biogas. You've… Read more
