Five-Step Lesson Plan Template Chemistry 1 90min Matter: Classifying Matter “Building the Universe” Objective(s): SWBAT classify different types of matter (DOK2) Essential Questions Big Ideas 1) What is the universe composed of? 1) classification Assessment Key Points 1. Which of the following could be considered as a molecule, but not a compound? A. CH3OH B. I2 C. H2O D. Kr 2. Which of the following would be considered as an element? I. Hydrogen gas II. Liquid nitrogen III. Diamonds (made all of carbon) A. B. C. D. 3. I, II, and III I and II I and III NONE OF THE ABOVE Which of the following would be considered a heterogeneous mixture? A. Kool-Aid B. Strawberry yogurt with fruit C. Cooking Oil D. The metal alloy brass 4. Jeromica received “chemical X”. She observed that it was a clear liquid and light could travel right through the glass. What type of matter could “chemical X” be? A. Element B. Compound C. Homogenous Mixture D. All of the above Knowledge 1. Matter: Anything that takes up space 2. Chemistry: the study of the composition, structure, and properties of matter, and the changes it undergoes 3. Atom: The most basic unit of matter. 4. Molecule: Two or more atoms combined together. 5. Element: A substance made of one type of atom 6. Compound: A substance made of one type of molecule 7. Pure Substance: A substance made of the same atom or same molecule 8. Impure Substance (Mixtures): Matter with more than one molecule 9. Heterogeneous Mixture: A mixture not uniform in composition 10. Homogenous Mixture: A mixture where light can shine directly through it 11. Tyndell Effect: If the substance scatters light when shined through the solution, then it is homogeneous. Skills 1. Classify matter as an element, compound, homogeneous mixture or heterogeneous mixture Opening (1min) Show a slide show of funny pictures of people, liquids, and gases. Also, have a mythical creature with the other pictures Which one of these pictures does not belong with the other? The unicorn does not belong with the others because it does not exist. Introduction to New Material (20min) What does it mean to exist in this world? And anything to take up space is? 1. Anything that takes up space is made of MATTER. Five-Step Lesson Plan Template Chemistry 1 90min The universe is made of two things, one of which is matter, and today we’re going to classify all this matter in this universe. Classify your hair, books, shoes, etc. In this class, we study chemistry, which is studying 2. the composition, structure, and properties of matter (or anything that takes up space) and the changes it undergoes -Bring out a lego model inside a plastic container. Have a student shake up the container. Can we break apart the building so much that the small pieces disappear? Okay, well now imagine taking a giant building and putting it into an enormous blender that chops the building for hours and hours and hours. Can the blender cut the building in such small pieces that the building disappears? Students should conclude that no matter how far you break something matter will still remain. Does anyone know what the individual pieces that make up everything is called? Atoms 3. Atom: The most basic unit of matter. Take two pieces of the building and put them together. Does anyone know what you get if you combine two atoms together? 4. Molecule: Two or more atoms combined together. What are some molecules that you might be familiar with? Write the chemical composition of common molecules on the board (e.g., H2O, CO2, etc.) Now, I’m going to write the chemical formula of just atoms. Write the chemical formula for just atoms (e.g., Pt, Ag, Au) How can you tell what is a molecule and what is an atom if we write out the substance? A molecule has two or more atoms! Show the students a list of elements and a list of compounds. What do all the substance in list A have in common? They are made of one type of atom from the periodic table. This is our first classification of the universe. An element. Show a large diagram of classification of matter. Have a picture looking “universal” behind the chart to reiterate in the essential question. 5. Element: A substance made of one type of atom What do all the substance in list B have in common? They are made of more than one type of atom. 6. Compound: A substance made of one type of molecule This is another classification of the universe. A compound. Introduce list C and D – homogenous mixtures and heterogeneous mixtures Now that you see a new classification of substances, what do you think list A and B have in common? They only have one type of substance in it. 7. Pure Substance: A substance made of the same atom or same molecule Five-Step Lesson Plan Template Chemistry 1 90min 8. Impure Substance (Mixtures): Everything other than pure substances Bring out a jar of sugar water and a jar of dirt. Have someone taste the sugar water. What was in the jar with a clear liquid? What molecules are in the jar with dirt? So are these pure or impure substances? Impure So the last classification that you need to know is that the mixtures you can shine light through are called 9. Homogenous Mixture: A mixture uniform in composition This is another classification of the universe. A homogeneous mixture. 10. Heterogeneous Mixture: A mixture not uniform in composition This is our last classification of the universe. A heterogenous mixture. 11. Tyndell Effect: If the substance scatters light when shined through the solution, then it is What might be a good way to remember the difference between homogenous and heterogenous mixtures? Homo- means the same, and if everything looks the same and you can shine a light through then it’s homogenous.
