Matter: Chemical vs. Physical Changes It is important to understand the difference between chemical and physical changes. Some changes are obvious, but there are some basic ideas you should know. Physical changes are usually about states and physical states of states. Chemical changes happen on a molecular level when you have two or more molecules that interact. When you melt an ice cube (H2O), you have a physical change because you add energy. Chemical changes happen on a much smaller scale. Melting a sugar cube is a physical change because the substance is still sugar. Iron (Fe) rusts when it is exposed to oxygen gas in the air. Some chemical changes are extremely small and happen over a series of steps. The sugars glucose, galactose, and fructose all have six carbon atoms, twelve hydrogen atoms, and six oxygen atoms (C6H12O6). Each of the sugars goes through different chemical reactions because of the differences in their molecular structure. Or search the sites for a specific topic.

Crystal Rainbows and Shamrocks We needed some St. Patrick's Day decorations in the house so I thought we could make some borax crystal shamrocks! Click here for my original post with instructions on how to make borax crystals. For the shamrocks I took one green pipecleaner and bent it into a shamrock shape. After 24 hours in the borax solution they looked like this! The rainbow was a little tricky. I put in 2 full scoops of borax {with the provided scoop}. Then I glued on some extra large cotton balls onto the ends of the rainbow to cover up the twisted ends of the pipecleaners. So pretty! I bet you think I will be making little crystal bunnies, eggs and flowers next...........yup I probably will! Have fun!

Rube Goldberg machine A Rube Goldberg machine, contraption, invention, device, or apparatus is a deliberately over-engineered or overdone machine that performs a very simple task in a very complicated fashion, usually including a chain reaction. The expression is named after American cartoonist and inventor Rube Goldberg (1883–1970). Over the years, the expression has expanded to mean any confusing or complicated system. For example, news headlines include "Is Rep. Origin[edit] Professor Butts and the Self-Operating Napkin In 1931, the Merriam–Webster dictionary adopted the word "Rube Goldberg" as an adjective defined as accomplishing something simple through complicated means.[4] Similar expressions worldwide[edit] Professional artists[edit] Peter Fischli & David Weiss, Swiss artists known for their art installation movie Der Lauf der Dinge (The Way Things Go, 1987). Competitions[edit] Rube Goldberg machine designers participating in a competition in New Mexico. Examples in media[edit]

Matter: Changing States All matter can move from one state to another. It may require extreme temperatures or extreme pressures, but it can be done. Sometimes a substance doesn't want to change states. Some of you know about liquid nitrogen (N2). Phase changes happen when you reach certain special points. Generally, solids are more dense than liquids because their molecules are closer together. There are always exceptions in science. Imagine that you are a solid. There is a special temperature for every substance called the melting point. If you were salt, sugar, or rock, your melting point is higher than that of water. You know about solids melting and becoming liquids. Can you go from a gas to a solid? ► More on Phase Changes in Part II...

20 Creative DIY Project Ideas We all have many old and unused items lying around in our homes or garages waiting to be thrown away. I don’t know if you’ve noticed, but there’s a great feeling of liberation that comes after shedding old stuff. However, before you start cleaning your home, we want to show you 20 incredibly creative Do It Yourself projects that may change your mind. You can turn an old glove into a cute chipmunk toy, toilet paper rolls into a beautiful floral wall art, plastic bottle into a broom and many more. We’ve been working on this list for a long time, but I’m sure there are many more awesome DIY ideas that we’ve missed. 1. More info: here | Buy: here 2. More info: here 3. More info: here 4.

The Best 100 Science Experiments | The MacDiarmid Institute In 2013, The MacDiarmid Institute in conjunction with (what was then) The New Zealand Teachers Council, launched a competition to find the The Best 100 Science Experiments for Kiwi classrooms. Primary School teachers from around the country entered their experiments, with the chance of winning a place in this "Experiment Bank". Here you will find resources for teachers and students for a great range of experiments. The competition will run again this year, with 100 experiments being the end goal. Nature of Science is the overarching, unifying strand of the New Zealand Science Curriculum. Physical World The physical world strand provides explanations for a wide range of physical phenomena, including light, sound, heat, electricity, magnetism, waves, forces, and motion, united by the concept of energy, which is transformed from one form to another without loss.

Dissection FAQ - Home Science Tools Q: Why dissect? A: Dissection is a valuable tool for visualizing the anatomical structure of different animal classes and species. The mammal specimens that we offer have similarities that are helpful for showing more about our own human bodies. For example, by dissecting and examining the anatomy of a cow eye, you can learn how your own eye uses a cornea, iris, pupil, connecting muscles and veins, and other features. Other specimens show the uniqueness of their species (such as a dogfish shark or crayfish). We actually learn anatomy more easily through dissections because we are simultaneously engaging the senses of sight and touch along with analytical thinking at the same time. Q: What do "single injected'' and "double injected'' mean? Q: Do the dissection specimens smell bad? Q: Are dissections hard to do? Q: What tools do I need? Q: Do I need to stick these things in the refrigerator? Q: Should I wear safety equipment? Q: How do I dispose of a dissected specimen?

Copyright © Restrictions By Ron Kurtus (revised 29 March 2012) A material will change from one state or phase to another at specific combinations of temperature and surrounding pressure. Names such as boiling and freezing are given to the various changes in states of matter. Questions you may have include: What are the changes in states called? This lesson will answer those questions. Useful tool: Metric-English Conversion Changes in states The states of matter are solid, liquid, gas and plasma. Order of changes When heat is applied to a material, its change in state typically goes from solid to liquid to gas. Melting Boiling
