Second Grade Science Projects (Page 23)

Science Fair Project Idea

Scientific Method

All animals have a genome, but do they all have genome projects? Find out which animals are currently having their genomes sequenced and how much we know already. Whose genomes are already finished? Whose genomes are just getting started? Find out by doing some simple bioinformatics data digging! Read more

Color Saturation

Science Fair Project Idea

Scientific Method

Lively, vivid colors can add pizzazz and turn a dull photo into a work of art. Learn how changing the saturation levels of the colors in your photo can really make it pop! Read more

The Swimming Secrets of Duck Feet

Science Fair Project Idea

Scientific Method

Do you wish that you had duck feet? Aside from being a fun Dr. Seuss story, there is a lot you can learn about hydrodynamics by looking at the feet of birds. How are the feet of birds that swim unique? Find out in this experiment. Read more

Time is Money

Science Fair Project Idea

Scientific Method

How many times have you heard from your parents: "Clean up your room!" or "Don't forget to unload the dishwasher!" By applying principles of industrial engineering and time management, you can speed through your chores and have more time to kick back and relax. Read more

Effect of Different Materials on a Magnetic Field

Science Fair Project Idea

Scientific Method

You've seen that a magnet's attractive force can cause a small object (like a paper clip) to "jump" to the magnet. So a magnetic field can act through the air, but what about other materials? Here's an experiment you can do to find out. You'll need a strong bar magnet, a stack of books, a paper clip, some thread and tape. Place the bar magnet underneath the top book in your stack, so that it sticks out. Tie a piece of thread (as long as the stack of books is high) to a paper clip. You… Read more

Temperature, Weather, and Air Movement

Science Fair Project Idea

Scientific Method

What are cold fronts and warm fronts? What happens when a cold front meets a warm front? You can test this using different temperatures of water. Use food coloring to label the cold and hot water, then carefully combine the two liquids together. What happens? How do they mix? You can also fill water balloons with hot or cold water, and then float in a hot or cold water bath. How does temperature affect the movements of the balloon? You can do similar experiments with hot and cold air in… Read more

Printing Power! Save the Environment, One Printer Page at a Time

Science Fair Project Idea

Scientific Method

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

Should We Walk Like Penguins? How Age Affects Your Stride

Science Fair Project Idea

Scientific Method

Watch out for that ice! When winter weather makes sidewalks icy, many people slip and fall. One tip doctors give is to walk like a penguin. That means pointing your feet slightly outward, keeping your center of gravity over your feet, and taking short, careful steps. Research has shown that these changes in stride and posture help people stay stable and avoid falls. These tips are especially helpful for older adults, who are more at risk of falling due to a decline in their balance as they… Read more

Timing the Tides

Science Fair Project Idea

Scientific Method

Have you ever been to a tide pool during low tide? Some intertidal animals in the low tide zone are left in a tiny pool of water when the tides go out. Other intertidal animals that live in high tide zones may be left to dry out during low tide. How much time does each zone spend out of water during a tidal cycle? Read more

Attractants and Repellants

Science Fair Project Idea

Scientific Method

Animals respond to chemical cues in different ways. If an animal turns away from a chemical cue, then that chemical is a repellent. If an animal turns toward a chemical cue, then that chemical is an attractant. Attractants and repellents can be airborne chemicals, chemicals found in food, or chemicals that diffuse through water. One example of an airborne chemical is a pheromone, a chemical signal that is released by one individual to attract another. Moths release pheromones to attract… Read more
