Step by step comparison interactive guide between mitosis and meiosis

NOVA animation comparing mitosis and meiosis.  Also includes brief explanations of what happens in developing egg cells versus sperm.

"Most of the time, when a cell in our bodies divides, each new cell carries a complete set of chromosomes. The cells involved with human reproduction, however, carry only half after division occurs. In this step-by-step explanation, learn about mitosis and meiosis, the two types of cell division."

"I went into a cell, to get out of the rain, and there was the gatekeeper, the cell membrane. I went into a cell, and what did I see, the mitochondria, it's the energy factory. I went into a cell, and said "who drives this bus" and found myself talking to the boss, the nucleus. ..."

"Here are words that will be helpful to students doing a hands-on science inquiry to view prepared slides of plant and animal cells to identify parts and learn the function of each. They relate their observations to the Essential Question: What are the parts of an animal cell and a plant cell? "

"Discover and explore the micro world of cells with this well design flash resource. Browse interactive diagrams of various types of living cells and try the quiz to test your knowledge."

"This is a newly revised 3 minute HD dramatic video choreographed to powerful music, which introduces the viewer to the wonder and miracle of cells. It is designed as a motivational "trailer" to be shown by Biology, Biochemistry and Life Science teachers in middle and high school and college as a visual "Introduction" to this amazing microscopic world."

"This particular algal species, commonly found in polluted water, is often referred to as "pond scum". As the movie switches to a 20x lens and then the 40x, watch closely, toward the center of each cell in the strand, for the cell nucleus. It's right near the middle and shows as a round object that is near transparent, but once you see it, you will see others. "

"This instructable will show you how to build a stand for about $10 that will transform your smartphone into a powerful digital microscope. This DIY conversion stand is more than capable of functioning in an actual laboratory setting. With magnification levels as high as 175x, plant cells and their nuclei are easily observed!  In addition to allowing the observation of cells, this setup also produces stunning macro photography."

Interactive online activity that provides an overview of protein synthesis, transcription and translation. Rated for Grades 9-12.

"This video created for high school biology students aims to illustrate the packaging of genetic material in the cell. Created for Sapling Learning in 2011. saplinglearning.com"

"How exactly does meiosis mix and halve chromosomes? Find out through this feature, which provides a step-by-step, side-by-side comparison of meiosis and mitosis."

"This program illustrates the mechanisms of photosynthesis and cellular respiration. It introduces ATP, the universal energy carrier molecules that supply energy-hungry reactions. It also shows the structure and function of Chloroplasts and Mitochondria, energy transforming organelles."

This is a fun Android and Apple app from University College London were players complete a range of games to exercise the brain cells and provide researchers with real, but anonymous data to use in their study. http://ictmagic.wikispaces.com/Science

Wolfram Tones is a neat offering from Wolfram that students can use to can play with sample sounds and rhythms to create new own sounds. Wolfram Tones uses algorithms, music theory, and sound samples to generate new collections of sounds. Wolfram Tones allows visitors to choose samples from fifteen different genres of music on which to build their own sounds. Once a genre is selected visitors can then alter the rhythms, instrumentation, and pitch mapping of their sounds. When satisfied with their creations, users can download their sounds or have them sent directly to their cell phones.

"This is a guest post by Joanne Manaster, a cell biologist and educator at the University of Illinois who writes a blog at Scientific American. She is active on social media as an advocate for STEM and science literacy."

From HHMI. A lesson that requires students to work through a series of questions pertaining to the genetics of sickle cell disease and its relationship to malaria. These questions will probe students' understanding of Mendelian genetics, probability, pedigree analysis, and chi-square statistics.
