An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form. 

Aristotle explained the idea of spontaneous generation, a concept which lasted almost 2,000 years before scientists proved it wrong. Scholars learn about the history of our understanding of the origins of life. They read examples of...

Wow! Here is a most-impressive series of lessons and activities that revolve around the classic story, The Tale of Peter Rabbit. The purpose of the lessons are to provide an agricultural theme in the reading, writing, and science...

Explore the center of gravity with your science class as they create a deadfall trap with common materials. They research the concepts of energy conservation and gravitational force before dividing into small groups to create a model of...

In this sixth of seven activities revolving around the concept of density, physical science fans figure out if anything can be done to change the density of an object. Demonstrate by placing a can of regular and a can of diet soda into a...

Reflection seems simple to understand, but without a complete understanding, pupils struggle with ray diagrams, specular versus diffuse reflection, total internal reflection, and image formation. An engaging interactive provides three...

If you weren't already blown away by first two installments, check out this clip on how gravity and space-time interact! Our physicist friends, Pontzen and Whyntie, continue their discussion of these motion concepts for your high...

What can layers of rock teach us about the climate? Young scientists solve a mystery about who stole a cookie by applying the law of superposition. Then, they apply the same concept to solve a more difficult mystery, trying to determine...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Does the mention of proteins and polypeptide relationships in your classroom result in mass confusion? Does the attempt to teach this important concept generate multiple questions and, at times, lead to a room filled with blank...

It may be time to get to know the skeletons in your family. The first lesson in a series of 5, introduces the class to the concept of osteoporosis. The class members brainstorm possible causes and whether the family should be concerned...

Four activities demonstrate the chain reaction of nuclear fission to your physical science fans: falling dominoes, snapping mouse traps, throwing paper wads, and igniting a series of matches. They perform additional...

Young scientists design a rocket to launch using Newton's Laws of Motion in order to discover for themselves the forces of motion. 

Pairs simulate the energy usage of different countries by drawing beads from a bag, which contain different beginning ratios of non-renewable and renewable energy resources. The activity concludes with a series of questions to tie...

In 2006, New Horizons began its mission to fly to Pluto. As it continues its journey, scholars track its progress with the help of an informative website, all the while reinforcing measurement concepts with the construction of a scaled...

How much time does it take to jump over three balloons? Pupils calculate the speed of tasks that require different motions. They determine motions for tasks such as walking, skipping, hopping, and jumping before creating a...

Many have debated which came first, the chicken or the egg, but this lesson debates which came first, the hydrocarbons or the carbonate reef. After a discussion on deep-sea corals, scholars receive a set of questions to research and...

How does temperature affect lipase activity? Young scholars conduct an experiment to collect data on the interaction of lipase at different temperatures. They add lipase to a solution of milk, sodium carbonate, and phenolphthalein and...

How do different parts of the world experience day and night? Introduce scholars to the concept of global citizenship while teaching about animal behavior with discussion of nocturnal and diurnal animals. Then, learners complete...

Demonstrate the ratio of surface area to volume in your high school class by using phenolphthalein, gelatin, and an onion. Intrigue the class by leading a discussion on osmosis and diffusion, then making "scientific jello." Participants...

Eugenics philosophy takes survival of the fittest to a whole new level. With a research-focused lesson, young scientists examine the history of the eugenics movement and its impact on society. Pupils engage with a video clip, primary...

Ready to teach your class about molar mass and solution concentration? Make time for an interactive resource that will challenge their reasoning and problem-solving skills. Science scholars calculate the molarity of several solutions...

Sprouting scientists explore the concept of density by making mass and volume measurements for five different liquids. From these measurements, they calculate densities. They apply their learning to explain Galileo's thermometer works...

Demonstrate how ice floats on water and get the class thinking about why icebergs are so deceiving. Investigators then experiment with mixing water of the same temperature and water of different temperatures. Make sure to explain the...
