Are you an XX or an XY? Budding scientists learn about cellular fertilization and the determination of gender in a thorough online lesson. They follow their study with a set of interactive reflection questions.

A pinch of adenine, a dash of thymine and ta-da, you have life! Well, it's not quite that simple, but through this series of activities and experiments young scientists learn about the structure of DNA and how it contains the recipe...

Students explore chromosome karyotyping. In this chromosome karyotyping lesson plan, students use a chromosome kit to explore chromosome syndromes and disorders. They also produce a large model of a cell with chromosome to simulate cell...

In this chromosome worksheet, students answer eighteen questions about chromatids, chromosomes, types of reproduction, haploid and diploid cells and zygotes.

Does day one of meiosis in your biology classroom make you wanna split? Get the class off to a great start using this attractive and thoughtfully worded slideshow. In addition to explaining what happens during each step of meiosis,...

What could be more real life than a biology course? Mt. Hood Community College offers a complete biology textbook with an emphasis on genetics. Topics range from DNA replication to biotechnology and inheritance patterns.

With AP Biology remaining the most popular AP science exam, many teachers need help preparing. The College Board offers the actual free-response questions from the 2017 test covering pollination, germination, and more. Scholars learn the...

In this environment worksheet learners complete a series of multiple choice and short answer questions on organisms, reproduction, DNA and cell division.

Your microbiologists explore a changing algae population and build an exponential function modeling algae concentration from the description given of the relationship between concentrations in cells/ml and days of rapid growth.

Packed with visual aids and multiple learning opportunities, an engaging exercise challenges individuals as they explore the role of producers, consumers, and decomposers. After discussing differences between food chains, food...

Students create and observe coacervates. In this origin of life lesson, students create coacervates by mixing carbohydrate and protein solutions. They observe the life-like qualities of the structures and discuss the origin of life.

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...

Put your heart into it. Scholars design and build replacements for mitral heart valves. Obviously, they can't test their creations on a real heart, so a box with marbles (to represent blood cells) will suffice.

Learners calculate the pixel density of a specific cell phone using the concept of similarity. They use information from the cell phone's website to make their calculations and then compare their results to the posted information.

Practice converting a conventional number into scientific notation, and vice-versa. Using an applet, they perform the operations of multiplication and division on numbers expressed in scientific notation.

Numbers that are very large or very small are difficult to express in standard notation. Pupils learn how to convert between standard and scientific notation. They also multiply and divide the numbers in scientific notation. 

Demonstrate the ratio of surface area to volume in your high school class by using phenolphthalein, gelatin, and an onion. Intrigue the class by leading a discussion on osmosis and diffusion, then making "scientific jello." Participants...

Remind your middle school scientists how fox ear size varies depending on the climate they live in; large ears allow heat loss while small ears keep heat in. Discuss how a cold-blooded animal might try to regulate body temperature. Then...

What an eccentric way to learn about each level of cellular organization! Allow emerging biologists to utilize white paper and create their own foldable charts to describe each level of organization in the body. You may also adapt the...

Diagrams with annotations are shown on each of these eighteen slides, which summarize the processes of respiration. The focus is on the 3-step oxidation process and the Krebs cycle.  Students should be able to follow these slides...

Provide high schoolers with their own indoor gardens! Emerging scientists discuss the process of photosynthesis and germinate seeds before growing plants in multiple lighting conditions. The hands-on application allows...

Learners comprehend that karyotyping is a process in which chromosomes are cut from an enlarged picture and arranged in decreasing order of size. The cells to be viewed are first chemically treated to increase the number of dividing...

In this counting galaxies worksheet, learners use a photograph taken by the Hubble Space Telescope and they divide the field into 16 square areas. They find the average number of galaxies in the cells, they find the area of one of the...

Fifth graders explore osmosis as they watch organisms divide.  In this organism lesson, 5th graders use potatoes to experiment with the effects of salty water in the body.  Students discuss what osmosis is and record what...
