Web Lab Directory Cell, Socks, and Sex Cell, Socks, and Sex Description: This is a fun, easy way to teach the process of mitosis and meiosis. This will strengthen vocabulary concepts like homologus pairs, diploid, haploid, tetrad and many others. This lesson will also clear up concepts like sexual determination, trisomy and even twining. Materials: Four or five pairs of socks. Lesson Plan: I start with a long, striped piece of fabric that has been twisted hundreds of times to represent chromatin material. I use socks with colored stripes, so that I can easily make reference to the genes in them, but add the idea of homologous chromosomes and alleles. I use a similar approach to teach meiosis. Now, I add the sex chromosomes to the original autosomal chromosomes. While singing Sthe race is on and here comes Clyde in the back stretch,S the sperm swims a bit and meets the egg.

If the Moon Were Only 1 Pixel - A tediously accurate map of the solar system Mercury Venus Earth You Are Here Moon Mars Jupiter Io Europa Ganymede Callisto Saturn Titan Uranus Neptune Pluto(we still love you) That was about 10 million km (6,213,710 mi) just now. Pretty empty out here. Here comes our first planet... As it turns out, things are pretty far apart. We’ll be coming up on a new planet soon. Most of space is just space. Halfway home. Destination: Mars! It would take about seven months to travel this distance in a spaceship. Sit back and relax. When are we gonna be there? Seriously. This is where we might at least see some asteroids to wake us up. I spy, with my little eye... something black. If you were on a road trip, driving at 75mi/hr, it would have taken you over 500 years to get here from earth. All these distances are just averages, mind you. If you plan it right, you can actually move relatively quickly between planets. Pretty close to Jupiter now. Sorry. Lots of time to think out here... Pop the champagne! We're always trying to come up with metaphors for big numbers.
