Matter

__**Matter** __ Can matter change?How do volume and shape help us define the 3 states of matter?Is gas really there?How do you know?If something has a different shape, does it automatically have a different volume?Does the band, They Might Be Giants, know more about science than Bill Nye? media type="youtube" key="tBQcpF_j5Xg?fs=1" height="385" width="480" align="center"

Use these as questions or make a few solid, liquid and gas cards to play the game.

Energy Energy is simply the ability to do work, to move or change an object with force. Bill Nye takes a look at potential and kinetic energy

There are many other different kinds of energy, here are just a few **Electrical**- anything you plug in! **Chemical** - digestion, batteries **Sound** - if you hear it, it has sound wave energy  **Light** - sun  **Heat** - hot water  **Kinetic** - wind, movement of any kind, describes many kinds of energy  **Potential** - the water in your toilet tank before you flush, stored energy of any kind, describes many kinds of energy  How many different kinds of energy do you see here? Talk about **potential**! media type="youtube" key="qybUFnY7Y8w?fs=1" height="385" width="640" Energy is constantly **changing** too! Just when we think we understand the difference between chemical, heat and electrical energy, they all start changing into one another!

Change Matter is changing all the time. We can change flour, butter, sugar, eggs and lemons into muffins! We can change snow into a puddle on the floor! Scientists think of change in two different ways: <span style="color: #000080; font-family: Tahoma,Geneva,sans-serif; font-size: 170%;">Chemical <span style="color: #008000; font-family: Tahoma,Geneva,sans-serif; font-size: 170%;"> and <span style="color: #ff00ff; font-family: Tahoma,Geneva,sans-serif; font-size: 170%;">Physical. <span style="color: #000080; font-family: Tahoma,Geneva,sans-serif; font-size: 170%;">Chemical change means the matter changes into a completely new thing that can't come back. <span style="color: #000080; font-family: Tahoma,Geneva,sans-serif; font-size: 22px; line-height: 33px;">The ingredients changed into a completely new thing: muffins. We'll never be able to get back the butter and eggs. <span style="color: #ff00ff; font-family: Tahoma,Geneva,sans-serif; font-size: 22px; line-height: 33px;">Physical change means the matter is slightly different, but hasn't become a different kind of matter entirely. The snow is now liquid, but it hasn't become orange juice or lava, it's still water. That water could become snow again in the water cycle. Not as tuneful as They Might Be Giants, but it has the bases covered.

<span style="color: #008000; font-family: Tahoma,Geneva,sans-serif; font-size: 230%; line-height: 33px;">Acid or Base? <span style="color: #008000; font-family: Tahoma,Geneva,sans-serif; font-size: 170%;">How can we think about such a thing as huge as matter? <span style="color: #008000; font-family: Tahoma,Geneva,sans-serif; font-size: 170%;">Well, some matter can be thought of as an acid or base. <span style="color: #ff0000; font-family: Tahoma,Geneva,sans-serif; font-size: 170%;">Acids have a pH number that is less than 7. <span style="color: #ff0000; font-family: Tahoma,Geneva,sans-serif; font-size: 170%;">They are often sour. <span style="color: #ff0000; font-family: Tahoma,Geneva,sans-serif; font-size: 170%;">Lime juice is a strong acid. Milk is a weak acid. <span style="color: #0000ff; font-family: Tahoma,Geneva,sans-serif; font-size: 170%;">Bases have a pH number that is greater than 7. <span style="color: #0000ff; font-family: Tahoma,Geneva,sans-serif; font-size: 170%;">They are often slippery and bitter. <span style="color: #0000ff; font-family: Tahoma,Geneva,sans-serif; font-size: 22px; line-height: 33px;">Ammonia is a strong base. Blood is a weak base. <span style="color: #008000; font-family: Tahoma,Geneva,sans-serif; font-size: 22px; line-height: 33px;">7 is neutral, like pure water. <span style="color: #008000; font-family: Tahoma,Geneva,sans-serif; font-size: 22px; line-height: 33px;">It is neither an acid nor a base. Here are some more acids and bases This video doesn't have the flair of Bill Nye, but it does cover the bases. media type="youtube" key="vpOkH7pnNqQ?fs=1" height="385" width="480" align="center"
