This science video tutorial includes step-by-step instructions for extracting DNA from wheat germ, the embryonic plant attached to the wheat seed. Individual wheat seeds, or kernels, separate readily from the plant. This kernels have a tough outer coating called bran. If you want to know more, just watch this science experiment.

Check out this instructional science video that demonstrates how to perform the DNA Extration experiment. From the Oregon Museum of Science and Industry's teacher curriculum, "No Hassle Messy Science with a Wow", this video shows you how to extract DNA from different organisms. Perform this experiment by following the simple step by step instructions outlined in this tutorial.

Check out this instructional science video that demonstrates how to perform the "Lost Labels" experiment. From the Oregon Museum of Science and Industry's teacher curriculum, "No Hassle Messy Science with a Wow", this is an activity about identifying mystery chemicals. You have an array of unknown powders in miscellaneous jars, and the idea is to try to have your students figure out what are all these mysterious white powders. Learn how to perform the Lost Labels science experiment by following...

Check out this instructional science video that teaches you about surface area. This is a NISE network demo training video for how to do a demonstration about surface area. By watching the step by step instructions outlined in this science tutorial video, you can learn all about surface area and the most effective method to killing germs.

Check out this instructional science video that demonstrates the details about the activity density rainbow. From the Oregon Museum of Science and Industry's teacher curriculum, "No Hassle Messy Science with a Wow", this is an activity demonstrating liquids with different densities. Perform the activity density rainbow experiment by watching the step by step instructions in this science tutorial video!

Check out this highly educational science video tutorial on how to stand an egg on end during the spring equinox, but wait... does it have anything to do with the spring equinox... no, it doesn't, standing an egg upright has nothing to do with the first day of spring. A lot of eggs have little bumps on the bottom of the egg, so the bumps actually help support the chicken egg when standing upright.

If you're an electrical engineer, you needn't worry about this educational video, but if you aren't...

Check out this instructional science video to learn how to make a soda pop can implode. You will need a torch, a Bunsen burner, or stove; a soda pop can with a tiny amount of water in it; tongs, or something to hold the can; and a bowl of ice water. This is a cool science experiment to perform, but adult supervision recommended. Follow the tutorial video's simple instructions and watch the soda pop can implode.

In this science tutorial video, watch as this cool trick to change a clock into a compass is revealed. Transform an old wristwatch into a compass with this simple and easy to remember instructional video. This is a very useful method for those who easily get lost to find their way again.

Check out this instructional science video to learn how to make a compass floating in glass of water. You will need a sewing needle, a standard refrigerator magnet, and a piece of toilet paper. Nestle the needle into the toilet paper and place it into a glass of water. The toilet paper will absorb the water and inevitably sink, but the needle will become an instant compass pointing north and south without fail. Have fun with this science experiment with the kids by playing with the magnet.

Check out how you can create three viscolastic effects with this how to video. A dyed polyvinyl solution crossed linked with sodium tetraborate in solution is found to exhibit the following three different viscoelatic effects:1. The Barus Effect (extrudate swell)2. The Weissenberg Effect (rod-climbing)3. The Kaye Effect (liquid leaping lanyards)These are great experiments to do with your kids. Watch this how to video and you can demonstrate three viscoelastic effects at home.

Check out this simple experiment using running water from a tap, and air blown through a straw, as it flows over the back of a vertically hanging plastic teaspoon are used to demonstrate the Coanda effect. Here the attachment of the back of the teaspoon to the flowing stream of fluid (air or water in this case) is what is referred to as the Coanda effect. Watch this how to video and you will be able to create the Coanda effect with your kids at home.

Check out this cool video and learn how to create the Allassonic effect with a coffee cup, instant coffee and boiling water. When the bottom of a ceramic cup filled with boiling water and a heap of instant coffee is tapped at regular intervals the pitch of the sound heard slowly increases over time.

Few household products can turn ordinary milk into cool solid balls. Check out this instructional science video to learn how to turn milk into solid balls using average household products. This is a great experiment to make with your kids. Just don't let them eat the balls.
