Proving microscopic structures exist is a difficult task. Learn how scientists did just that in the mid-1800s as they set out to identify the cellular structures related to genetics. The online lesson explains the collection of work that...

I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms...

Connect Mendelian genetics with Darwinian theories. An interactive lesson lets pupils explore how George Shull used research from other scientists to explore genetic variation. The resource outlines the statistical analysis of genetic...

Heat things up in your physical science class with this interactive lesson series on thermodynamics. Through a series of class demonstrations and experiments, young scientists learn how heat is transferred through conduction,...

Winter, spring, summer, and fall—take the learning of the seasons beyond the elementary level to the middle school classroom. Curious learners begin by watching videos about the seasons and the rotation of planet Earth. Then,...

A celestial body's distance from Earth makes studying its characteristics much more difficult. Learn how scientists use indirect measures to determine the size of stars. The interactive activity has individuals adjust the size of binary...

You may not be able to take a field trip to the moon, but that doesn't mean your class can't study moon rocks. Using graham crackers as the moon's bedrock and powdered donuts as micrometeorites, young scientists simulate...

Look around and explore. Little ones use their five senses with some day-to-day activities designed to guide observation and apply STEM strategies. Young scientists learn through comparing/contrasting and...

Take your class on an out-of-this-world adventure with this fun engineering design lesson. Working in small groups, young scientists design, build, and test crew exploration vehicles using some creativity, teamwork, and...

What is the relationship among the heart, circulation, and exercise? Your class members will explore first-hand how different physical exercises affect an individual's heart rate. They will begin by learning how to measure their own...

Don't lift another finger, this physical and environmental science unit has everything you need to begin teaching your class about energy. Starting with a look at the greenhouse effect, these lessons and activities take young scientists...

Some scientists dedicate their lives to researching and protecting endangered species. An online lesson teaches about three scientists around the world who do just that. They learn about spiders, mollusks, and reptiles from North...

Time to rock and roll! Young scientists test their knowledge about rocks found on Earth and what they tell scientists. A 10-question quiz focuses on the different types of rocks, how they are formed, and what they are made of.

Your young forensic scientists add to and strengthen their measurement and conversion skills with these seven well-scaffold worksheets. Metric conversions, measuring length, area, and volume, reading thermometers, graduated cylinders,...

A pinch of adenine, a dash of thymine and ta-da, you have life! Well, it's not quite that simple, but through this series of activities and experiments young scientists learn about the structure of DNA and how it contains the recipe...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

The lesson allows young scientists to use lasers and mirrors to study reflected light. A reading passage and homework question assess learning, while additional material introduces extension activities. 

Young computer scientists continue programming with while loops by creating a program to simulate coins flipping. 

Build learning by breaking atoms! Young scientists study the way energy changes with a hands-on activity. As they roll steel marbles down a ramp, learners test the hypothesis that kinetic energy does not go away with friction...

Are you an XX or an XY? Budding scientists learn about cellular fertilization and the determination of gender in a thorough online lesson. They follow their study with a set of interactive reflection questions.

Who actually likes leeches? Meet a scientist that makes his living letting leeches feed on him. Pupils learn about the characteristics of leeches and different variations of the species. The lesson works as a remote learning resource or...

Humans have only inhabited the earth for a fraction of the time that life has existed. Young scientists explore the facts about the emergence of life on Earth with an interactive resource. While highlighting different types of life, the...
