Twelfth graders explain relationships and interactions between species, the difference between a fundamental niche and a realized niche. They explore the various species interactions from their classmates through the jigsaw activity.

Learners comprehend the difference between monotremes, marsupials, and placental mammals. They are able to compare and contrast these organisms (Australian mammals) with other mammals. Students are able to identify Australian mammals.

In this language of science worksheet, students use the list provided to guess the meaning of each of the list. Students apply root words, prefixes, and suffixes to gain meaning of other science words.

Students identify the main concepts and ideas of the nitrogen cycle. They review key concepts covered up to this point in ecology including food chains, food webs, energy pyramids, and bio-geochemical cycles.

Students pretend to be enzyme that breaks toothpicks in timed intervals. They complete calculations to determine how many toothpicks are broken per second to determine the rate of reaction of the enzyme.

Young scholars use this activity to establish a new mode of reference to the conceptualization of time. To present hominid evolution in terms of millions of years and endosymbiosis of eukaryotes in billions of years carries little...

Young scholars determine the relationship between leg length, stride length, and speed in humans and bipedal dinosaurs. They collect data and graph these human characteristics then use actual data collected from dinosaur track pads and...

Students are able to explain the relationship between adaptation and ability for survival and reproduction. They are able to give examples of a series of adaptations that would support the idea that evolution is a series of minor...

Students are organized into groups of four. On Day 1 they are given a worksheet about viruses and their effects on the evolution of a rabbit population. After about 30 minutes of group work, a class discussion of the material begins. ...

Students start to think of evolution in terms of populations. The class follows a cartoon scenario of a rabbit population in which there is selection and change of gene frequency. They receive copies of the scenario or the whole thing...

Students use this activity as a logic problem that is based on real organisms and real data. The problem is to develop phylogenies for seven related populations of lizards living on the Canary Islands. Three phylogenetic charts are...

Students engage in solving a logic problem based on real organisms and real data. They develop phylogenies for seven related populations of lizards living on the Canary Islands.

Young scholars read and analyze an obituary written for Charles Darwin. They make a list of facts about Darwin they learned from the obituary. Students compare Lamarack's theory to Darwin's.

Students distinguish between active and passive transport. Students identify key words associated with active and passive transport. They draw and explain the structure f the cellular membrane. They are able to define phospholipid...

Students research coral reefs and identify their benefits to humans, threats to the reef, how to reduce and eliminate threats, and more. In this coral reef lesson plan, students research the reefs, and take a field trip to an aquarium.

Students define bioplastics and identify its uses.  In this bioplastics lesson, students compare and contrast styrofoam to starch peanuts after careful examination.  Students understand what biodegradeable means.

Students examine how plants are able to adapt to their ecosystem and the role that fire plays in changes through the years.  In this ecosystem lesson students complete several exercises focussing on plants and their adaptations to.

Students identify the three realms of the Arctic Ocean, and describe the relationships between these realms. They identify major factors that limit primary productivity in the Arctic Ocean.

Young scholars discover the uniqueness of deep sea hydrothermal vent organisms through an exploration of the NOAA Galapagos Rift Expedition. They study the genetics and evolution of a shrimp species that lives near the vents then they...

Students compare and contrast key skeletal differences between chimpanzees and humans: brain size, teeth, hand and thumb, trunk, pelvis, lower limb, foot and big toe. They then sort and group a set of mixed "fossil bones" of chimpanzee...

Students explore early hominid evolution as they analyze bones that share characteristics of both apes and humans. Students compare and contrast key skeletal differences between chimpanzees and humans. In groups, they sort and group a...

Students identify the three realms of the Arctic Ocean, and describe the relationships between these realms. They graphically analyze data on sea ice cover in the Arctic Ocean, and recognize a trend in these data.

Students model a paleontologist's activities. They identify dinosaur bones and reassemble them into a skeleton of an extinct reptile.

Students construct a timeline of four major culture periods in Native American history from studying archaeological evidence cards.
