Did you know the average American eats 250 eggs per year? That equals a total of 76.5 billion eggs per year eaten in the United States alone. Whether you like them boiled, scrambled, sunny side up or as an omelet, eggs is a main staple food in most of our diets.
Eggs are filled with nutrients that are good for your body. They are a good source of protein (help you build muscle) and healthy fats (help you feel full and satisfied). Eggs also contain a wide range of vitamins and minerals that boost brain development and cognitive memory, fight illness and promote bone health.
Besides their nutritional value and delicious taste, eggs are also great for science experiments! With World Egg Day approaching, we’ve rounded up a few “eggs-periments” that incorporate STEM:
Investigating Air Pressure: This science experiment from Science Sparks demonstrates air pressure by using it to force an egg into a bottle. Adult supervision is required, as this experiment involves matches.
Observing Osmosis: Did you know eggs are mostly water? Discover the process of osmosis with this naked egg experiment! Students will observe different liquids - such as vinegar, corn syrup and salt water - permeate the egg’s shell and record how each liquid affects the eggs.
Exploring Density: Try this sink and float experiment with a twist to test the density of fresh- and saltwater. Spoiler alert: the egg floats in the salt water. The salt makes the water more dense causing the egg to float on the water’s surface.
Testing Strength: Eggshells seem fragile and delicate, but they’re stronger than you may think! Test eggshell strength to see how much weight an egg can hold. Can it hold a pile of books? Two quarts of water? Try it out and see!
Discovering Physics: Join in on the egg drop challenge and encourage students to design a contraption using various materials to protect a raw egg from a high fall. The contraption that keeps the egg intact after the fall wins the challenge.
Growing Crystals: This crystal geode experiment not only teaches sedimentation, but also produces beautiful, sparkling crystals. It only takes two days to complete the experiment and students will love the outcome!
While eggs are great for eating, they are also great for conducting science experiments with students. Try the above experiments to combine egg fun with important concepts like physics, osmosis and air pressure.
