Students examine the year's cycles by observing the four seasons, their distinctive weather patterns that affect our activities and the weather changes that each brings. The fourteen lessons of this unit offer a good opportunity for the...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

Ever wonder how they solve those mysterious murders in TV crime dramas? The second of four units in a Biotechnology series introduces scholars to the many methods of DNA analysis. Pupils create and run their own gel electrophoresis...

Learners explore the emotional and nutritional needs of teenagers in a six-lesson unit, which covers such topics as food sources, cooking skills, emotional well-being, and the positive effect of food and family occasions. 

Biotechnology is big! Introduce the uses of biotechnology to science scholars with a fascinating, fact-filled unit. The first installment in a series of four biotechnology units covers the role biotechnology plays in human and...

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

Do you want to learn about how you learn? Help pupils become the best learners they can be by teaching them how their brain works. The resources available include videos about brain structure and a study guide full of activities that...

In this STEM group of 10 activities, lesson two focuses on the question, "Just because we can, should we?" when considering genetically engineered food. Classes hear a scenario and, as young scientists and geneticists, must determine if...

Students examine the topics of ocean waves, currents, and tides. They locate and label ocean currents on a world map, conduct experiments, analyze key vocabulary, view demonstrations and record the data, and complete handouts.

[Free Registration/Login may be required to access all resource tools.] Take a look at the groundbreaking organic molecules formed millions of years ago. Study the RNA that might have been that first organic molecule. In Earth's early...

[Free Registration/Login may be required to access all resource tools.] Examines how the first organic molecules were formed. The experiment of Stanley Miller and Harold Urey is explored along with the RNA world hypothesis.

When is a molecule polar? Change the electronegativity of atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how shape affects polarity. See how it works...

When molecules collide, chemical reactions can occur -- causing major structural changes akin to getting a new arm on your face! George Zaidan and Charles Morton playfully imagine chemical systems as busy city streets, and the colliding...

This video explores the spacial property of chirality and how it relates to molecules and the everyday world. Followed by a short quiz and a list of additional resources to explore. [5:05]

When two or more atoms combine they give rise to a molecule. A molecule can be made up of many atoms of the same element. There are 112 elements known to man, so can you imagine the different permutations and combinations of molecules...
