New ReviewMany 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...

New ReviewWhat'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...

New ReviewSalamander embryos provide scientists with the first evidence of mitosis. Learners complete an animation to learn about the discovery and the process of cell division. The resource emphasizes the phases and includes a description of each.

New ReviewCells 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.

New ReviewCan 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...

New ReviewSome genetic conditions occur without being inherited. The distinction becomes the focus of the lesson. It details the process of cell division that results in trisomy on various chromosomes. A worksheet highlights the results including...

New ReviewBased 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...

Sex chromosomes determine gender, but how? An informative video presentation discusses meiosis with an emphasis on the structure of the sex cells. Viewers learn why the X and Y chromosomes are so important.

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...

Why do some organisms reproduce sexually, others reproduce asexually, and some both? Biology scholars examine the pros and cons of sexual and asexual reproduction through a short, informative video. The resource offers great examples of...

Why do siblings often look so different from one another? Discover the process of making gametes using a short video from a large biology playlist. The narrator explains each step while animated chromatids play out the scenario that...

Birds, bees, flowers, trees ... and Funisia dorothea? Biology scholars journey back in time to discover more about the history of sexual reproduction. The video, one of many in a biology playlist, covers our earliest eukaryotic ancestor,...

Make sure your unit on trait variation causes a sensation! Take an in-depth look at standard LS3B, an important component of the Next Generation Science Standards. The narrator discusses methods of delivering the standard to younger...

Use chromosomes in marketing because as you know, sex cells. The video explains both mitosis and meiosis. It focuses on both the similarities and the differences in the process of forming sperm, egg, and zygote.

During meiosis, one cell divides twice, forming four daughter cells. The video explains the stages of meiosis in great detail. It begins with interphase and DNA replication, meiosis I, meiosis II, and finally the four haploid cells.

"We Are Never Ever Getting Back Together" makes the perfect theme song for meiosis. The simulation encourages scholars to move the chromosomes and chromatids to properly illustrate the meiosis break up. Multiple-choice questions allow...

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...

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,...

Can you name a type of reproduction that produces no variation in the offspring? The multimedia lesson covers both sexual and asexual reproduction through videos and discussions. It includes topics such as genetic modification, meiosis,...

The third in a series of 10 STEM project-based lessons focuses on cells types, functions, and physiology. Through research, discussions, writings, and presentations, groups learn about the difference between plant and animal cells, the...

Potatoes have more chromosomes than humans. A video explores the number of chromosomes various species have and the theories of the differences. It discusses the process of how genes combine as well as the processes of making extra copies.

If identical twins had children with identical twins, would their children also be twins? The short answer is no, and the video explains why by relating the DNA of siblings to that of identical twins and the long-term implications of the...
