A Milk Jug Skeleton is a Fun Recycled Craft Decoration for Halloween Years ago I created one of these Milk Jug Skeletons for Halloween. Just recently I was cleaning out my craft room and came across the directions again and thought I would share for those who have never seen it before. My Milk Jug Skeleton I think got lost in one of my many moves years ago and now that I have found the pattern I think I may have to create another one. This Skeleton would be a craft for an older child or adult since there is a lot of cutting involved, but it is well worth the effort. Not only does it look cool, but you are also recycling all those Gallon Milk or Water Containers into a Halloween Decoration that is sure to bring lots of conversation when the Trick or Treaters come to the door. As you can see from the photo to the left that you can also add some Glow in the Dark Paint onto the Skeleton so that when it is dark out he will Glow while he hangs there.

Great Websites to Teach Anatomy of Human Body in 3D September, 2014 looking for some amazing web tools to teach human anatomy? The websites I have assorted for you below are probably among the best you can find out there. From engaging interactives to live simulations of the body system, these tools will enable your students to explore the mystery of the human body in unprecedented ways.

Amusement Park Physics Design a Roller Coaster Try your hand at designing your own roller coaster. You will be building a conceptual coaster using the physics concepts that are used to design real coasters. Engineering for the Three Little Pigs Lesson from Teachengineering.org was contributed by the Integrated Teaching and Learning program at the University of Colorado, Boulder’s College of Engineering. It is part of the Engineering for the Earth curricular unit. Summary Students learn about the importance of using the right materials for the job by building three different sand castles and testing them for strength and resistance to weathering.

Bottle rocket This experiment demonstrates how a build up in pressure can launch a rocket. As we pump air through the water the pressure inside the bottle builds up until the force of the air pushing on the water is enough to push the cork out of the end of the bottle. The water rushes out of the bottle in one direction whilst the bottle pushes back in the other. Making Your Life-Sized Body (Organs) - Activity Return to the Anatomy Activities Index Making Your Life-Sized Body (Organs) - Activity Anatomy Activity What if you stopped drinking water? What would actually happen to your body if you stopped drinking water, including all beverages that contain water, like juices, soft drinks, and tea? Let's just say it wouldn't be pretty - your body is made up of 60 percent water, which is reason enough to make sure you're constantly replenishing your supply. All that water works really hard to ensure that you continue functioning properly, by transporting vital nutrients and hormones to where they need to go, cushioning our joints, regulating our internal temperature, and lubricating our eyeballs. But we lose a whole lot of it through processes such as urination - about 1.5 litres a day - defecation, and sweating, so we need to know when we should be upping our intake.

History of the Periodic Table Figure 4-2. Dmitri Mendeleev Created the Periodic Table That We Still Use Today © The Regents of the University of California, Lawrence Berkeley National Laboratory, 2010. View More Figure 4-2. Dmitri Mendeleev Created the Periodic Table That We Still Use Today Experiment with Magnet Magic Is your child struggling to get a handle on the principles of magnetism? Here's a fun activity to demonstrate polarity and understand the basic principles of magnetism. Before you start, brush up on the properties of magnets to get a feel for the way they work. Properties of Magnets: 7 Videos of People Rescuing Animals Some people can be pretty terrible to animals—but most people will try to help cuddly (and not-so-cuddly) creatures when they can. Here are some of the most incredible videos of people saving animals. 1.

The Compound Interest Periodic Table of Data Today’s graphic is one that I’ve been working on over the past couple of weeks. Every chemistry classroom has a Periodic Table, but it’s often a drab affair; considering it’s one of the cornerstones of chemistry, I thought I’d attempt to produce a more dynamic looking version. The result is the above table – each element is shown within a circle that contains a variety of data pertaining to that element. The data shown for each element is as follows: Melting point in degrees celsius.Boiling point in degrees celsius.First ionisation energy in kilojoules per mole.Atomic radius in angstroms.Electronegativity (on the Pauling scale).Density (in grams per centimetre cubed (g/L for gases)). The Pink Underwing Moth: Skull-Faced Caterpillar of Australia’s Rainforest Nature never ceases to astonish. This is the larva of the Pink Underwing Moth, an endangered species which lives in the subtropical rainforest below about 600m elevation in the Australian states of New South Wales and Queensland. It has evolved a remarkable set of patterns to ward off potential predators. A giant set of eyes would, you might think, be enough to warn off a bird looking for an easy lunch. Yet this caterpillar goes one step further. It appears to have a set of teeth which could rip any possible attacker to shreds.

Practical Chemistry This website is for teachers of chemistry in schools and colleges. It is a collection of experiments that demonstrate a wide range of chemical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Chemistry is a practical science.
