  1. Do Now • Take out your packet from yesterday • What are the 3 states of matter? • How is state of matter related to energy (heat)? • Describe the difference between elements, compounds, and mixtures

  2. Objective • SWBAT review the atoms and states of matter unit, and the elements, compounds, and mixtures unit Essential Question • We will have time to create our own questions for Jeopardy tomorrow. Try to make them difficult

  3. Atoms • Everything in the universe is made up of tiny particles called _______. • Atoms cannot be _______ into smaller pieces. atoms divided

  4. Diagram of an atom

  5. States of Matter

  6. Changes of State For each word, write from ________ to ________ and gains/loses energy solidification: from liquid to solid losing energy Condensation gains energy loses energy

  7. Density • The equation for density is ___________________________ • Density is a _____________ between the amount of ________ an object has and the amount of _______ (volume) that same object takes up. Metals such as iron, gold, and lead have ______ densities and will feel _________. Gases such as oxygen, and nitrogen, which have a mass, have ________ densities and are very ____. Density = Mass/Volume relationship mass space high heavy low light

  8. Units for Mass and volume • Mass • Grams • kila • milla • Ounces • Pounds • Volume • mL • cm3

  9. Elements and Compounds • Elements are always composed of the same type of _______. All of the elements on the periodic table are ___________ of elements. ____________ form when 2 or more __________ elements form __________ bonds. Compounds of the same elements have very different ___________ of the individual elements. atom examples Compounds different chemical properties

  10. Elements vs. Compounds • For example, ________ (Na) is a highly reactive Alkali Metal and ________ (Cl) is a highly reactive Halogen. Sodium and chlorine chemically combine to form NaCl (sodium chloride) more commonly known as _____. • Elements have symbols of 1 or 2 letters and there will only be 1 ________ letter. • Compounds will have ________ 2 capital letters, sometimes many more. sodium chlorine salt capital at least

  11. Compounds vs. Mixtures • Compounds and mixtures are different because of ___________________________________. Compounds can only be separated by breaking the _______________ between the elements. Breaking the chemical bonds will _______ new substances. Mixtures can be separated by physical means. Some examples of physical separations are _________, distillation, breaking, using a magnet, _______________, density, ________, and others. When mixtures are separated, no new substances are __________. the way that each can be separated chemical bonds create sorting change of state gravity formed

  12. Homogeneous vs. Heterogeneous homogeneous • A ______________ mixture is when a mixture is ________ throughout. Each substance is ______________ throughout the whole mixture. A _____________ mixture is not uniform throughout and the _____________________. Some examples of _____________ mixtures are sand, and saltwater. Some examples of _______________mixtures are oil and water, sand and water, uniform equally spaced heterogeneous mixtures are separated homogeneous heterogeneous

  13. Sample TCAP questions • Complete the questions independently • When you are done, try to create some questions that I can use in the Jeopardy game tomorrow • Write them on a sheet of paper and put them in the exit ticket basket • Include your name for a shout-out and if your question is chosen for a 500 point question you will get a piece of candy • Volume level can be above a whisper at level 2
