How To: Grasp and calculate human blood pressure regulation

Check out this science-filled two-part video tutorial on blood pressure regulation in humans. This educational video will show you the MABP (mean arterial blood pressure), which is the overall blood pressure in your body, the TPR (total peripheral resistance), and the CO (cardiac output). You won't just learn about the blood pressure, you'll see how to calculate the MABP. You'll be fascinated, whether you're a physiologist, biologist, scientist, medical student, or just an human anatomy nut.

How To: Grasp the human physiology of the heart

Want to know what a septum is? An aorta? The bicuspid valve? These are all parts of the human heart, and in these educational tutorial videos, you'll learn all you need to know about the physiology of the human heart. Anatomy, biology, physiology... it's all science, so no matter what field you are studying, these will be very helpful for you in your further medical studies, or for just know-it-all knowledge.

How To: Use a Peltier module to create free electricity from heat

A Peltier module allows you to turn heat into electricity. Because you can place it in areas that are normally warm anyway, the electricity created is "free" in a sense, though it does work best when one side of the module is cold and the other is hot. In other words, all you'll need for this project is the Peltier module and a cooler surface such as soil or water, and a warm area such as a well lit window or warm pan.

How To: Dissect the eye of a cow

Check out this video tutorial on how to dissect the eye of a cow. If you like science, and you like animal anatomy, then why not go out and get your own cows eye for dissecting, and more importantly, learning? You'll see the cornea, the iris, the ciliary muscle, the eye tissue, and more.

How To: Dissect a sheep brain to compare to a human brain

This seven-part video tutorial will take you through the steps necessary to dissecting a sheep brain so we can learn and compare it to a human brain. You'll learn about the different kinds of memory in the brain, and that's not all. So, for this science anatomy of the brain dissection project, go down to the local slaughterhouse and get yourself a brain. Abattoirs are a great place for brains. Dissect a sheep brain to compare to a human brain - Part 1 of 7.

How To: Dissect a frog and look at its anatomy

This video tutorial will show you the steps on how to dissect a frog. First, you'll have to get a frog, then you'll have to make sure it's dead, then perhaps wash it off. Then just take a look at the external anatomy of the amphibian before slicing it open. To slice, you'll need dissection forceps or tweezers and the dissection scissors. From then on, you'll be knee deep in frog anatomy. Tons of internal organs for you to learn from. So, watch this science video for learning about the anatomy...

How To: Make glowing water

This video tutorial will show you how to make glowing water. You can use as an ingredient to make other science projects glow in the dark, such as crystals and slime. All you need is a highlighter pen and some water. Check out this how-to video and go make some glowing water.

How To: Make colored patterns in milk

Learn how you can do this beautiful science experiment that your kids will love with this tutorial. All you need for this experiment is two colors of food coloring, milk and dish soap. Follow the steps in this tutorial and you can create crazy, psychedelic designs in milk for hours.

How To: Build a faraday motor

Build a faraday motor with tips from this how-to video. In the early 1800s, physicist Michael Faraday invented the first device to convert electrical energy into mechanical motion. This is an easily built version of his motor. The magnet sets up a magnetic field, and the electrical current through the screw sets up a separate electromagnetic field around the screw. The two fields react and the result is rotation.

How To: Make ozone

Make ozone with tips from this how-to video. (You probably don't really want to intentionally make ozone--it's more of a mistake or byproduct). It can't hurt to know how it's made, nevertheless. Make ozone.
