You never know what you will find next in the deep sea ecosystem. So far, scientists have found items that work as anti-tumor agents, anti-inflammatory agents, agents that stop uncontrolled cell division, and much more. The lesson begins...

In this second lesson of the series, pupils learn to observe similarities and differences in photos of the sun and record them in a Venn diagram. Then, small groups practice the same skill on unique images before presenting their...

When judging diversity of an ecosystem, both species evenness and species richness must contribute. After a discussion of diversity and a guided example using the Shannon-Weaver function, scholars use the same function on two other...

After three eye-opening lessons about our environment, scholars revisit a 10-question survey, reflect on their new-found knowledge, and take action by writing to a representative or creating a public service announcement about...

Boost observational skills and get to know the difference between deciduous, coniferous, and evergreen trees with a lesson that challenges scholars to compare, contrast, identify, sort, and draw their findings.   

Blast off! An engaging hands-on activity has pupils create rockets powered by Alka-Seltzer. They learn about the physics behind these rockets throughout the process.

Model hardness testing with a self-designed hardness test. Young scholars rate the hardness of different types of aspirin using the Vicker's Hardness scale. They then relate hardness to the solubility of each aspirin tablet.

"i before e. . ."  Spelling is easier if kids know the eight basic spelling rules  contained in this resource packet.

Add visual representation to teaching place value with a magnitude model. Using adding machine tape, pupils build a linear place value strip from 1 to 100.

Imagine an ecosystem without any light or oxygen, where living things convert carbon dioxide into food. This ecosystem is thriving and might just be the largest ecosystem on our planet, yet we know very little about it. The lesson...

Discover the connection between electric current and magnets. Scholars create electromagnets by passing a magnet through a coil. They experiment with different materials to determine the variables that affect the strength of the current.

Watch the excitement grow as learners experiment with homemade rockets. Pupils create their own rockets from a soda bottle and experiment with launch angles. They discover the launch angle has a significant effect on the distance the...

What can you contribute? Scholars read text to determine how ants contribute to the rainforest. First, they categorize and sort facts gathered from reading. Next, readers focus on specific terms in each paragraphs of the text Ants by...

How easy is it to live off the land? Scholars read Minerals and Metals in Your Life and discuss how Canada's natural resources meet the needs of the people. Pupils watch a brief video and discuss the gist of the text and video. They...

In 2006, New Horizons began its mission to fly to Pluto. As it continues its journey, scholars track its progress with the help of an informative website, all the while reinforcing measurement concepts with the construction of a scaled...

Young entomologists construct three types of insect traps—pitfall, pollinator, and panel—before setting their traps out and observing what they caught. They then observe what types of insects the different traps attract.

Space shuttles traveled around Earth at a speed of 17,500 miles per hour, way faster than trains, planes, or automobiles travel! In the 13th installment of 22, groups graph different speeds to show how quickly spacecraft move through...

A radio receives radio signals, converts them to an electrical signal, then converts this signal to a sound signal, and amplifies the sound so people can hear it. Class members use this information to create a short-wave radio antenna...

Can you listen to Jupiter on a simple radio? Turns out the answer is yes! The resource instructs scholars to build a simple radio to pick up the radio waves created when the charged particles from the sun hit Jupiter's magnetic...

The theory of keystone species in an ecosystem was first established in 1969 by Robert T. Paine. Pupils open the final lesson in a five-part series with a game guessing which member of the alpine ecosystem they are based on clues. After...

How did the earth become the mass that it is now? Your young scientists explore this question through the concept of density. Their inquiries consider the impact of gravity on the formation of planets. The culminating activity of the...

What makes up a habitat? Use this resource to engage first graders in the exploration of desert, wetland, forest, and ocean habitats. Youngsters classify plants and animals into the four distinct habitats through drawings and cutting and...

Mammals are some of the newest organisms to appear on Earth. Young scholars complete an activity that results in a timeline showing the appearance of different types of living organisms. Provided with a list that spans from prokaryotes...

Can the force of falling water through a tube vary by altering the diameter of the tube or its height? That is what physical scientists aim to discover in this activity, the third in successively more revealing activities on the power of...
