Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

What is coral bleaching? Tackle a trendy topic with a narrated animation. Through a combination of video and illustration, the narrator introduces viewers to a coral reef, then goes inside a coral polyp to show its symbiotic relationship...

This is one cool resource for teaching about polarity! Chemistry scholars observe electron distribution and molecular shape as they select different non-metals and form bonds. The interactive offers two views, surface charge and electron...

The average person's heart beats about three billion times during their lifetime. In this circulatory system video, learners briefly see the difference between an open and closed circulatory system. The rest of the video focuses on the...

From hydrogen to ununoctium, this collection of videos has everything you need to begin teaching about the periodic table. Offering descriptions of each element and interesting experiments demonstrating their properties, this resource is...

The thinking, and science, behind hydrogen-powered cars is beautifully demonstrated in this episode. Spangler shows how, by itself, oxygen is not combustible. However, when some hydrogen gas is added, that changes! His assistant scoops...

In this observation worksheet, scientists observe a burning candle and answer eight post-lab questions. Topics include the phase changes occurring during the observations, the role each part of the candle plays in the chemical reaction,...

Salman Khan is very enthusiastic about the topic of cellular respiration! He provides an interesting presentation of the respiration process. Expect to learn about the basic stages of respiration, how it works in the human body, and the...

This topic builds on the previous video. It deals with the equation of respiration and whether electrons or hydrogen are being lost or gained at the different stages.

During an inquiry-based lesson, scholars decide which variable to test and then design an experiment to determine the needs of producers. After two weeks, they complete a full analysis and research paper.

Chemistry is the foundation of good farming. Learners explore how chemical bonding applies to agriculture. The lesson highlights the difference between organic and inorganic compounds and how similar compounds bond in very different ways.

Curriculum resources can be expensive—but not this one. An online textbook offers informational text for a complete high school Biology course. Topics include energy flow, body system, genetics, and evolution.

Trees are the star of a three-step unit celebrating Arbor Day. Step one takes an in-depth look into the structure of a tree, the process of photosynthesis, and the benefits of the leafy giants. Step two challenges scholars to create a...

Most fish freeze to death when the water is too cold, yet some fish live in the Southern Ocean where the water is often below freezing. Scholars use two models representing the blood from most fish versus the blood from Antarctic fish....

Is there life on Mars? Is it likely? A video lesson analyzes the possibility of life on Mars. The discovery of water on Mars changes how scientists think about the likelihood of life on the red planet. Part of the SciShow Space series,...

Can complex life develop in an oxygen-depleted environment? Scholars listen to a discussion of the topic between two people: one interested in science without studying it and one working on a doctoral degree in science. The fourth video...

Is your class ready to size up the topic of diffusion? Help them get cell shape savvy with a well-written handout. The resource covers how substances such as oxygen passively move through the cell membrane and how cell size and shape...

How does energy from the sun make plants grow? Scholars move step by step through the processes that promote plant propagation during a detailed lesson. The resource illustrates ADP production and hydrolysis, then allows learners to...

Earth didn't always have oxygen, so what caused the change that allows humans to live here? Learn about the change in O2 levels throughout geological history through an interactive graph. Each section offers greater detail on the changes...

Was Earth born as a Blue Planet? Discover where water came from with a video from an intriguing science playlist. The resource covers the three most likely origins of water, how scientists differentiate between comet and asteroid water,...

Take it all the way back! Young scientists discover the changes that took place from the time Earth became solid to present day through an interesting interactive. The resource guides users through key events that have shaped our world...
