Students experiment with currents caused by temperature variations that simulate the origins and flow of polar bottom currents. They discover water density is affected by temperature and salinity, resulting in deep water currents.

In this lab, students explore how organisms are able to survive the extreme environmental conditions found in the Polar regions. Students observe and draw active living rotifers and Tardigrades, design and perform experiments to collect...

Seventh graders role play the roles of naval engineer apprentices. In groups, they work together to design a ship which cannot be damaged by freezing ice. They use the internet to research the weather and ocean conditions of the water...

Students estimate the size of a molecule of oleic acid. They conduct an experiment using chalk dust, water, and oleic acid, solve various calculations, and answer discussion questions.

Students discuss glaciers and the current distribution of glaciers around the Earth. They create simulated glaciers using cornstarch, shoeboxes, water, and pebbles.

Amateur chemists define and describe properties of solutions, compare solubilities, explain how solutes affect freezing and boiling points, describe acid and base properties, and more! This educational PowerPoint provides information and...

Your students will love this PowerPoint! Great visuals will support understanding of membrane proteins, cell membranes, active transport, and diffusion. There are a lot of details on each page and all are relevant. The presentation could...

After reading a short excerpt about the planet named after the Roman god of war, Mars, your class will answer four comprehension questions. The activity challenges them to fold over the paper and answer the questions without referring...

Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...

Young scholars use real satellite data to determine the changes in near-surface air temperature at different times of the year over the Caribbean Sea. They discover how Earth's tilt causes seasonal differences in incoming solar energy....

This is not they typical set of teacher instructions. It is an organized chart of the important organic compounds. For each, the involved elements, the name of the building block monomers, the names of polymers, extra information, and a...

Students create a paper model to illustrate sea-floor spreading.

A fantastic presentation with great images should improve student understanding of lipids and their involvement in the body.  The chemistry of different fats, phospholipids, and steroids are explained. Additionally, the specific...

Course identification information is included in the upper left corner as well as within the title of this worksheet. If you overlook or remove that information, you are left with a tremendous college biology assignment. There are only...

In this solutions, suspensions and colloids worksheet, students use diagrams to show how particles are different in each of these mixtures. They also distinguish between characteristics of each of these types of mixtures and categorize...

Plankton isn't just a tiny cartoon character, it's also a very important food source for animals around the world. Budding scientists discuss the types and functions of plankton, including where they are found, how they are caught, and...

A marine environment covers the majority of the earth but is arguably the least understood. Teach young scientists about the characteristics of oceans and ocean species using an interactive online lesson. The in-person or remote learning...

Explore the world (our world) of melting ice caps. Why are these caps melting? What is the effect of melting ice caps? Dive into the ever-present issue of global warming with a resource that has learners looking at data and participating...

What factors make up climate? How does longitude and latitude affect climate? What is causing Earth's climate to change? These questions are the topic of a presentation that explains characteristics of climate and climate change.

Develop an understanding of the universe. Learners answer 10 multiple choice questions about several topics in astronomy. Questions contain information about the age of the universe, gravitational attraction, galaxies, planets and comets...

Scholars read about each planet then bake a plate of cosmic cookies—no-bake cookies decorated to look like the planets; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.

Ecology aces examine sea surface temperature maps and relate temperatures to concentration in fish and zooplankton populations. Take your class to a computer lab and provide experience with actual remote sensing data. Some of the links...
