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...

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...

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...

How can you effectively provide detailed concepts of water properties to your high school class in a way they find exciting and challenging at the same time? By letting them play, of course! Through a variety of...

In a sweet simulation, junior geneticists examine the chromosomes of a fictitious Reebop marshmallow animal, combine chromosomes to produce offspring, and then make a model of the resulting Reebop baby. Phenotypes include number of...

Springboard your fourth and fifth graders into the study geologic time. They will complete 7 activities to learn about geologic time and the topics most often associated with it: astronomy, creation, planet formation, volcanology,...

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...

Biology learners should understand a few chemistry basics. Here is a instructional activity that introduces them to the concepts of chemical reactions, molecular bonding, and the unique combination of properties that make water vital to...

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...

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. 

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...

Physics fanatics time five cars as they pass on the highway. They use the times and a 20-yard distance to calculate velocity. They also graph distance vs. time. A page of student pre-lab questions is provided in addition to the activity...

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...

Even light cannot leave the force of a black hole! Learners use a model to explore the gravitational force of a black hole. An elastic bandage and heavy ball serve to create the hole, while marbles become the victims of its strong force.

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...

Primary graders are introduced to the concepts of pitch and volume with a reading comprehension worksheet that focuses on the physics of sound.

How fun would it be to teach the concept of stoichiometry while allowing your chemistry class to assemble a classic campfire treat? This fun and engaging activity allows pupils to explore the principles of the chemical theory while...

Get things moving with this extensive collection of physical science resources. Covering the fundamentals of measurement, graphing, lab safety, and experimental design as well as the specific scientific concepts...

Learning about the mole using rice is pretty nice! Help your chemistry scholars visualize the concept of a mole of substance with an easy-to-perform lab. Partnered pupils find the mass of a single grain of rice and relate this...

Introduce organic chemistry through an analysis of flavor. A three-part unit begins with an overview of the components of flavor. Next, scholars prepare esters through esterification. Finally, they examine how all senses have an impact...

We have all heard the debate about teaching both theories, but an innovative lesson takes the discussion to a new level. Scholars research and debate Newton's Law of Gravitation versus Einstein's General Theory of...

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...

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

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...
