New ReviewAn eight-unit electronic textbook provides a guide to AP® Biology. Each of the 28 chapters include an introduction, multiple lessons, a summary, review questions, and test prep questions. Teachers see how each lesson connects to a big...

Mosses and liverworts do not have any vascular tissue, unlike other plants. Young scientists learn more about these rootless plants through hands-on dissection and research on their life cycles as they get their hands dirty for a fun...

Ever been told you have your father's eyes? How did it happen? Young biologists get a hands-on experience in meiotic gene expression with a fun pairs-based activity. Participants use pipe cleaner chromosomes with trait beads to make...

If every human on earth looked exactly the same, the world would be a boring place. Thank goodness for genes! Pupils explore the difference between haploid and diploid cells by learning how two parents without red hair can produce a...

It is hard to believe a 300-foot-tall Redwood tree began as a single cell hundreds of years ago. How did it grow so large? Observe how different kinds of cells (bacteria, sex cells, and eukaryotic cells) reproduce or make more cells for...

For scholars tired of reading the textbook, this unit includes nine hands-on lessons. Through group work, lab activities, experiments, and even one inquiry-based lesson, scholars apply knowledge about cells, genetics, and biotechnology....

Reebops are cute, marshmallow-based creatures that can be used to teach inheritance. Beginning biologists draw strips of paper that represent chromosomes from two envelopes, one for the father, and one for the mother. Each parent...

Young biologists define reproduction vocabulary terms, answer critical-thinking questions, label a diagram of the human life cycle, and complete a chart comparing mitosis to meiosis. This is a well-balanced learning exercise. Even though...

Investigate the ins and outs of cell division with this comprehensive set of activities. Detailed instructions for six different activities and your choice of eight different creative assessments can be found within this resource. By...

Fill- in-the-blank, labeling, and short answer questions make up this well-written cell division worksheet. Neat diagrams of chromosomes and dividing cells are included. Junior biologists show what they know about reproduction, meiosis,...

Whenever your students have a question about a stage of mitosis, you can be sure that viewing the relevant slide from this show will help their understanding. Covering the complete process of mitosis, this PowerPoint has images and...

Six pages begin with a detailed introduction to meiosis and homologous chromosome pairs. Instructions guide learners through a simulation in which they draw craft sticks marked with autosomes in order to decode the genes inherited by...

How diverse are living things? Individuals explore topics such as cells as the foundation for life, cell division and genetics, molecular biology, and animal reproduction using an open resource Biology textbook. They learn key terms...

Do young scientists know that some traits are only passed down by the mother? Mitochondrial DNA is an interesting phenomenon that provides researchers with a lot of useful information. Scholars learn about the endosymbiotic theory, what...

Why do people age? Scholars explore the concept of telomeres and why they are so important in cells. They learn about the role of telomerase and why it is active in some cells—but not in others. The video also explains why some organisms...

Have you ever wondered why calico cats have such a colorful coat? The process of X inactivation is an interesting phenomenon in females that drives the physical appearance of individuals. Viewers of an intriguing video connect knowledge...

Many future doctors earn college science credit by passing the AP biology test while still in high school. Help young scientists prepare for the exam by studying past test questions. Each of the eight questions covers multiple topics...

What's the difference between body cells and sex cells? Learners explore the question and the process of meiosis using an interactive lesson. An animation describes the discovery of meiosis and describes its phases for a detailed and...

Cells divide by one of two processes, either mitosis or meiosis. Scholars sort cards into two sets, one representing each type of cell division. Then, they sequence the cards demonstrating an understanding of the movement of chromosomes.

Can you describe a gamete without using the words sperm or egg? Scholars play a vocabulary review game where they try to get other players to guess their words. Each card has the target word as well as two related words they must not...

Based on current scientific knowledge, all cells come from preexisting cells. Scholars learn about cell division, cell replication, mitosis, meiosis, and more with a PowerPoint. It describes the differences between prokaryotes and...

Sex sells, or in this case, sex cells allow reproduction to occur. Scholars view a presentation and animation as well as complete a worksheet on meiosis and gamete production. They observe every stage and learn about the function and...
