In this review of evolution worksheet, students complete 50 multiple answer questions on Darwin's theory and the history of life on Earth.

The various experiments and processes that were completed in the 20th century to further our understanding of DNA are summarized here. There are wonderful slides to popularize the scientists who dedicated their professional life to...

This quiz just looks neat! It has two cell diagrams for biology class members to label. They also describe the function of each organelle. A prokaryotic and eukaryotic cell are displayed for them to compare, and then they fill in the...

Explore the history of cholera and its effect on society with your biology class. Young biologists will then proceed to grow their own germs, prepared from live cultures, and follow the steps of the scientific method to generate data....

What happens when a non-native species is introduced onto an island? Santa Cruz Island, part of the Channel Island chain located off the coast of southern California, provides the perfect laboratory for young environmental scientists to...

If you are looking for a great way to present natural selection in humans, look no further. This handout is intended to accompany the 14-minute video The Making of the Fittest: Natural Selection in Humans, which can be found on the...

What is in that double helix? Explain intricate concepts with a variety of creative activities in a lesson that incorporates multiple steps to cover DNA structure, nucleic acids, and proteins. Pupils explore the history of DNA structure,...

Provide your class with the opportunity to view our carbon cycle close up. Young scientists research the cycle of oxygen as it completes the tasks of photosynthesis and respiration. They explore the importance of carbon in an ecosystem...

What better way to learn how to use a microscope than building your own? A lab investigation has scholars use lenses from magnifying glasses and sheets of cork to design their own compound microscopes. They calculate focal length...

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...

One of the most striking pieces of evidence for Darwin's Evolution of Species was his observations of finches and how their beaks differed from island to island, depending on their primary food sources. So what would happen to the theory...

In this Earth's history activity, students will complete 5 true or false questions based on the early history of the Earth. Students will match 7 fossil vocabulary words to their definitions. Students will complete 4 short answer...

High schoolers are able to define microbes and identify the five main groups of microbes. They are able to give examples of ways in which microbes have impacted or currently impact human life. Students are able to explain that not all...

Middle schoolers discover that material and energy uses by a city come from outside the city boundaries. They realize that the pathway of these material is linear instead of cyclical as they are in natural ecosystems.

In this history of life activity, students will use diagrams of the Precambrian, Paleozoic, Mesozoic, and Cenozoic Era to complete 4 fill in the blank statements.

In this history of life worksheet, students use diagrams showing how life may have begun on Earth to complete 3 short answer questions.

A lively presentation presents general facts and history of nucleic acids in a note-taking format. Every slide contains colorful photos or graphics to illuminate and engage. Biology aces learn about the function and structure of...

Students explore the effects of different density-dependent and density-independent factors on population growth. They explore how the interactions of organisms can affect population growth. Students explore the pattern of population...

Wow! A very detailed slideshow covers complex topics of genome research methods. This is advanced and relevant to the highest level of school biology. Excellent resource if you wish to expose your class to scientific methods and...

Ancient coral beds give scientists clues to past ocean temperatures in much the same way that tree rings indicate historical weather conditions. High school scientists examine coral oxygen isotope ratios and plot the data as a function...

A presentation that truly covers the age of reason and enlightenment. Nearly every facet, event, and key player in 18th Century Age of Enlightenment is covered. The information is clear, easy to follow, and lends itself well to note...

Young biologists discuss the reasons behind the current use of the plant identification system. They get into groups and identify the characteristics of each species of plant which is described. The keys needed for groups to make...

Second in a three-part instructional activity on rivers, this instructional activity focuses on the flooding that occurs in riparian locations. First, learners take a look at facts about the Amazon River. They read online materials and...

Scientists recently discovered several previously unknown species at the Bear Seamount off the coast of New England. Scholars research these new species — benthopelagic, benthic, and seamount fish — and find out what makes them...
