Why is the ocean vital to our planet? There are many reasons, but one important one is that the ocean is a major player in regulating our weather and climate through currents. In this lesson plan, your students will model ocean currents with cups, water, and food coloring, and explore how temperature and density differences set deep ocean waters in motion to create a global oceanic circulation system.

NGSS Performance Expectations:

MS-ESS2-6. Develop and use a model to describe how unequal heating and rotation of the Earth cause patterns of atmospheric and oceanic circulation that determine regional climates.

Oil Spills

Science Fair Project Idea

Scientific Method

No one can deny the devastating consequences of an oil spill on the local wildlife. Oil affects all levels of the ecosystem, from plants to fish and birds. What happens to water plants if you add motor oil to their pot? What is the effect of motor oil on the health of a goldfish, or water insects? What happens to the barbs of a bird feather if they are dipped in oil? Can you test different types of environmentally-friendly detergents for cleaning the bird feathers? Can you test different… Read more

One Bad Apple Spoils the Whole Bunch: An Experiment on the Plant Hormone Ethylene

Science Fair Project Idea

Scientific Method

We have all heard the old saying, "One bad apple spoils the whole bunch." Due to the production of the plant hormone ethylene during the ripening process, this saying proves true! This experiment will investigate the role of ethylene in the process of fruit ripening. Read more

Out of Control!

Science Fair Project Idea

Scientific Method

Have you ever watched an inexperienced video game player pick up a controller and start playing a game? Often the player bumbles around trying to figure out which button makes the onscreen character jump, run, turn left, or perform other actions. Some games are different though, they have control schemes that are more real-world based. For example, most modern Mario Kart games give you the option of steering with a joystick or turning the entire controller like a steering wheel, which is more… Read more

Ozone Depletion

Science Fair Project Idea

Scientific Method

The ozone layer is important for blocking most of the harmful radiation that comes from the sun. You can find maps of the ozone layer and compare different regions of the globe for ozone coverage. Where are the problem areas? Is there a difference in ozone coverage between different hemispheres? Between populated and un-populated areas? In atmospheric regions over land masses or over bodies of water? Some scientists think that aerosols in the air are breaking down the ozone layer. You can do… Read more

Paintball Ballistics

Science Fair Project Idea

Scientific Method

Have you ever played paintball with your friends? Wonder how you can improve your game? Paintball guns use compressed gas to shoot paint-filled pellets at high speed, and with good accuracy. The flight path of the ball is determined by its speed and the angle at which it is shot, relative to the ground. In this sports science fair project, you will explore the ballistics of paintballs, focusing on how drag and other factors affect the results. Read more

Paper Bridge for Pennies

Science Fair Project Idea

Scientific Method

Using just a single sheet of paper (8.5 x 11 inches) and up to five paper clips, can you build a bridge that will span 20 cm and support the weight of 100 pennies? The area beneath the span must be free (so that boats can pass beneath it). To test your bridge, place two books 20 cm apart, and set the bridge on the books, spanning the gap. Do not fasten the bridge to the book (nor to any other support). Does your bridge hold as much weight as you expected it would? If your bridge fails… Read more

Paw Preference in Pets

Science Fair Project Idea

Scientific Method

The great majority of people have a distinct hand preference. How about animals like dogs or cats? Do they show a paw preference? If you like animals, this science fair project might be for you. Read more

Have you ever spent time spinning a hula hoop around your waist or arm? Could you easily do it, or was it difficult? Have you ever wondered how hula hoops work, or, in other words, what makes them be able to spin around a person's waist or arm? It comes down to the physics that is involved. Physics can help you determine what makes one hula hoop a winner and another a flop. In this activity you will get to create your own hula hoops and investigate how their masses affect how they spin. … Read more
