Two blooms of phytoplankton, instead of just one, now occur in the Arctic due to declining sea ice, which will have widespread effects on the marine life and climate. In small groups, participants build an Arctic food web with given...

Air, air, everywhere, but what's in it, and what makes Earth's air so unique and special? Journey through the layers above us to uncover our atmosphere's composition and how it works to make life possible below. Pupils conduct...

Small but mighty! Learners explore the role of microbes in a healthy ecosystem. An engaging lesson asks pupils to design an aquaponics system that demonstrates that healthy microbes are necessary to maintain the ecosystem.

Mercury, Venus, Earth, and Mars are collectively known as the terrestrial planets. Although part of the same group, each planet has its own set of characteristics. Scholars explore the characteristics that make the planets unique and...

Students investigate the lives of frogs by completing several worksheets.  In this biology lesson, students discover the life cycle of a frog from tadpole to death.  Students complete frog life cycle puzzle as well as create a...

Seventh graders compare/contrast the life cycles of free-living organisms to that of parasites. They conduct Internet research, illustrate the stages of a specific organisms's life cycle, and direct and produce a mini-video production.

Seventh graders examine the life cycle of the human. In this human life cycle lesson, 7th graders discuss the many different stages of the human life cycle. Students use pictures from magazines to create a representation of the human...

Almost 200 slides make this a vast collection! It is a quirky collection, titled "Marine Fisheries Management," but having little to do with that occupation. What you will find are two-toned blue backgrounds with no pictures, but a few...

Learners examine health and safety issues in the workplace. They, in groups, discuss how health and safety issues effect their lives.

Students read Lincoln: A Photobiography by Russell Freedman. They complete a variety of cross-curricular activities surrounding the life of Abraham Lincoln, including, but not limited to, the Civil War. Included are reading, art, math,...

It makes sense to sniff out a good lesson on the sense of smell. Here is a six-slide presentation that can be a strong component to that lesson! With photographs and expository graphics, life scientists find that smell is the detection...

What's in a cell, anyway? Kids read informational text on what makes up both animal and plant cells, including a page of vocabulary terms they will need to be familiar with (cytoplasm, ribosomes, vacuoles, etc.). Full-color images...

Hedgerows prevent soil erosion, capture pollutants running off fields, store carbon to help combat climate change, and provide homes for predators of many pest species. The biodiversity lesson begins with an activity that...

Climate change is a hot topic in the news. Class members examine carbon dioxide data to analyze trends of our atmospheric makeup over time. They also discuss climate and climate change, and determine how these changes are affecting life...

Using stunning computer imagery, this resource introduces life science learners to cells. It zeros in on the animal cell and the function of its more prominent organelles. Additional support is offered in the form of a self-assessment...

Some scientists argue that air pollution now causes more deaths than smoking. The second unit in a six-part series focuses on air quality. Scholars learn what's in the air, how clean the air around their school is, and what they can do...

Space diving refers to the act of jumping from outer space and falling through Earth's atmosphere before parachuting to land. Scholars learn about this extreme activity and study the layers of the atmosphere they must conquer in the...

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

Lub-dub, lub-dub. Why does the heart beat? Why does blood circulate throughout the body? Life scientists find out how important circulation is for dissolving and dispersing materials by timing how long it takes for food coloring spread...

Galapagos Penguins are the only penguins on earth that live north of the equator (in the wild). In this last lesson plan a discussion on how the Galapagos islands developed their populations and diversity sparks the introduction. Two...

Here is a collection of 22 multiple-choice questions on topics from the physical and life sciences. Apparently they came from an 8th grade comprehensive science exam and have been released for public use. They may serve as a sufficient...

Only five slides, but worth the while for introducing upper-elementary zoologists to different animal life cycles. Two types of metamorphoses are explained: complete and incomplete. Stunning photography flows before the eyes of the...

What happens to stars as they get older? A simulation takes pupils through the life cycle of stars based on their masses. The resource introduces the Hertzsprung-Russell diagram and the common relationships and life cycle patterns observed.

Charles Darwin and Jean Baptiste Lamarck are credited for developing the theory of natural selection. After teaching your beginning biologists about acquired characteristics, they read the included selection and answer questions that...
