Matter, Part 4 Review

 Re-watch the videos titled “Matter Part 2” and “Matter Part 3.”  Pay careful attention—you’re not watching a movie, you’re watching to learn information.  Take notes on each section. Even though you can always go back and watch the video, taking notes activates another part of your brain. Remember, we talked about the fact that engaging more parts of your brain with information (writing plus listening plus watching) equals better learning! Re-watch videos

 me what the mistake was if you were able to find it. Did you find the mistake in Matter Part 3?

 If you have trouble coming up with some of the answers, review the videos entitled “Matter 2” and “Matter 3.”  The basic information is in the videos, but you might have to use some thinking skills to come up with some original answers or apply the facts to something new.  (eeeeeeeekkkkkkk. Not thinking—why does she always insist we THINK!!!) Give yourself this quiz

 Review Review from Matter 1, 2, and 3

Physical Properties of Matter We’ve done experiments and demonstrations that show density, appearance, color, and texture. Conductivity is whether or not sound, heat, or electricity will travel through the substance. Ductility is the ability to be hammered into thin sheets, while malleability is the substance’s ability to be shaped and formed. Viscosity is a liquid’s resistance (or lack of resistance) to flowing. Lustre is how shiny (or not shiny) something is. Magnetic attraction, metallic/non- metallic, odor, and appearance seem pretty self-explanatory.

Review from Matter 1, 2, and 3 Chemical Properties of Matter Reactivity is whether or not a specific substance (for example water, or acid) will cause a chemical reaction with the material and form a new substance Solubility involves whether or not the substance can be dissolved in something—water, or air, for example. Flamability seems pretty self- explanatory—will it burn, or won’t it burn. Electrolysis refers to whether molecules can be separated into their elements by passing electrical current through them.

 What is a pure substance?  Define, and  Give some examples.  What is a mixture?  Define, and  Give some examples.  What is a solution?  Define, and  Give some examples. 1.1 Students will differentiate between a mixture and a pure substance.

 Here are some common compounds and some common elements. Can you figure out what elements combine to form the compounds?  The compounds are listed in the dark green boxes, and the elements are listed in the lighter green boxes. Fill in the blue boxes with the elements you think make up that compound. Students will describe the different atoms and molecules in mixtures.

Calcium Oxide (lime) CaO Hydrochloric Acid HCl Caustic Soda (Lye) NaOH Na-SodiumAu-GoldO-Oxygen Cs-CaesiumCr-ChromiumNi-Nickel He-HeliumCl-ChlorineCa-Calcium H-HydrogenPo-PoloniumCu-Copper Students will describe the different atoms and molecules in mixtures.

 What is it called when you separate matter by particle size?  Give some examples of how you would separate matter by particle size.  What is it called when you separate matter by density?  Give some examples of how you would separate matter by density.  What is it called when you separate matter by solubility?  Give some examples of how you would separate matter by solubility.  What is it called when you separate matter by boiling point?  Give some examples of how you would separate matter by boiling point. Students will demonstrate how using the properties of the substances from which they are made (such as particle size, density, solubility, and boiling point) can help separate mixtures.
