People have five senses that they use to interact with the world around them: sight, hearing, taste, smell, and touch. Sight is the ability to see and is used to help us navigate and understand our surroundings. For example, we use our sense of sight to see the colors of flowers, the shapes of objects, […]
Plants are living things that have different parts that help them survive in their habitats. These parts include roots, stems, leaves, and flowers. Roots help plants anchor themselves in the ground and absorb water and nutrients from the soil. Stems support the plant and help it grow taller. Leaves use sunlight to make food for […]
Animals are amazing creatures! They have many ways of using their bodies to survive in their homes. All animals have body parts that help them to survive in their habitats. For example, some animals have sharp claws to help them catch their prey for food. Others have long legs to help them run away from […]
It took a child named Erasto Mpembra to discover that hot water freezes faster than cold water. No adult would even consider testing such a wild theory. Mpembra was curious, and discovered knowledge new to science at the age of 13.
There are more microorganisms in a handful of soil than people on Earth. This includes millions of species and billions of organisms—bacteria, algae, microscopic insects, earthworms, beetles, ants, mites, fungi, and more.
Evolution is a foundational principle within biology that forms the basis for many other theories. The theory of evolution was first described by Charles Darwin, a scientist who lived during the 19th century. Darwin’s theory proposed that all species on Earth have descended from a common ancestor and that new species arise through the process […]
Legend states that gravity was discovered by a man named Issac Newton as an apple fell from a tree and hit him in the head. The more you consider this story though, the less likely it seems to be factual. Did no one understand gravity before Newton? Was he the first person to realize that […]
Issac Newton’s Third Law of Motion states that for every action, there is an equal and opposite reaction. This law is the basis for many things we see in everyday life, from the way a rocket propels itself through the air to the way a person pushes against the ground to walk. It is also […]
Issac Newton’s second law of motion states that the acceleration of an object is directly proportional to the force applied to it, and inversely proportional to its mass. In other words, the heavier an object is, the more force is required to accelerate it. The formula for this law is: F = ma Where F […]
Issac Newton’s first law of motion is the law of inertia. It states that an object will remain at rest or in motion until an external force acts upon it. What does this mean? Imagine that an object, such as a ball, is moving through space. How long will that ball continue to move? According […]
