As you work through the biological hierarchy, visit several phyla within the animal kingdom. This PowerPoint introduces viewers to characteristics and reproduction in sponges, cnidarian, flatworms, and roundworms. Make sure to add the...

Zoologists tour of the worlds of reptiles and birds when viewing this presentation. The physical characteristics, methods of reproduction, homeostasis, and special senses of each are detailed. Diagrams include the reptile egg, bird...

Carolus Linnaeus designed the binomial nomenclature system of naming organisms that is still in use more than 200 years later. By viewing this PowerPoint, upcoming biologists learn how to use it. They are also introduced to the hierarchy...

Journey through the world of seedless plants with this visually appealing PowerPoint. Physical characteristics of mosses, liverworts, ferns, horsetails, and club mosses are detailed in bullet-point fashion. If possible, have living...

The first slide lists the six kingdoms in the biological hierarchy, but the remaining 10 slides cover characteristics of archaebacteria and eubacteria. Topics include how energy is obtained, arrangement, and shape. This brief, but...

Biology novices name the seven levels of classification and use binomial nomenclature for naming living organisms. The first half of this presentation bestows a brief history of taxonomy, while the second half instructs on how to use our...

Marine biology apprentices interpret data of sturgeon interaction with gill nets. They use the data to calculate the percentage of fish entangled in each twine size to discover if there is any correlation. This is a valuable exercise in...

Inform your class about the adaptations in fish eyes: cones, lens size, endothermy, and speed of vision. The adaptations are related to diving behavior. Junior marine scientists compare the adaptations of four different fish species to...

Explore the practice of oyster gardening. Because oysters play a vital role in marine ecosystems and their populations have declined, biologists are transplanting oyster seed to repopulate reefs. After learning about this practice,...

Here is an outstanding presentation on protista. It lists general characteristics, and then moves on to describing three different categories of protists. For each, viewers learn physical features, behaviors, and means of reproduction....

How do people get sick? Youngsters explore the world of germs and microbes with a lab sheet and science investigation. After identifying the unhygenic practices in a picture of a kitchen, fifth graders conduct an experiment with bread...

Biology buffs simulate how genetic markers are passed among populations in order to understand how these markers can help anthropologists map human migration. A couple of volunteers leave the room while you walk the remaining learners...

In a nutshell, your class will culture bacteria from their choice of surfaces. You will need to prepare or purchase agar plates. If you are new to this classic biology activity, this resource carefully walks you through the process of...

One of the key concepts in life science and biology is the cycling of energy throughout an ecosystem. Learners can take notes on the topic using the vocabulary included within the presentation. From producers making their own food...

This editable worksheet is set up so that biology pupils read four case studies and identify points that are present in each, such as overproduction, heritable variation, struggle to survive, and differential reproduction. They also...

Biology or health nuts select a disease to research and produce a pamphlet that can be used to inform the public. The tri-fold product is worth 100 points according to the included grading page.

A presentation on Darwin's theory of evolution and natural selection could be a good addition to your biology class. It provides general information about how animals adapt to their surroundings, as well as how organisms create more...

What animals are best suited for moving around a rainforest, or a desert? Design your own animal species based on a particular habitat, focusing on the characteristics it will need for optimal movement. Great as a group lesson or...

Young scientists get to the heart of the matter with this comprehensive review of the circulatory system. Addressing the different anatomical structures and processes involved in pumping blood through the human body, this activity...

Take your biology class on an exploration of the inner workings of cells with this multimedia presentation. Looking closely at the structure of cell membranes and the processes of osmosis and diffusion, this resource explains for...

Frequently found in biology and economic application problems, exponential equations show up as stars in this introductory presentation. Taking no background or knowledge of exponentials for granted, the slides walk learners...

Chart ecological community interactions and answer questions about niche, defenses, trophic structure, and succession. This community ecology worksheet provides a general overview of the interactions that occur among organisms that share...

The classic in-class demonstration using celery dipped into water with food coloring is the highlight of this biology lesson plan. Young scientists discover that organisms are made up cells and have distinguishing characteristics. After...

Andree Walker thought of everything when he wrote this resource. It includes a detailed list of materials and background information links for the teacher. In addition, it has procedures, a macroinvertebrate identification key, and tally...
