Today’s Agenda • • • • • • Objectives Periodic Table Intro Periodic Table Activity Discussion/Share Outs Homework #11: Periodic Practice Ticket to Leave Objectives Scientists will be able to predict where an element falls on the periodic table based on its criteria. New Vocabulary: Proton Repeat After Me: Proton Definition: The positive part of an atom. It is a subatomic particle. Other Forms: Protons New Vocabulary: Electron Repeat After Me: Electron Definition: The negative part of the atom. It is a subatomic particle. Other Forms: Electrons New Vocabulary: Neutron Repeat After Me: Neutron Definition: The neutral part of an atom. It is a subatomic particle. Other forms: Neutrons Introduction to the Periodic Table Video Elements, Compounds and Mixtures! We use the periodic table to organize the elements. Scientists will be able to predict where an element falls on the periodic table based on its criteria. Elements, Compounds and Mixtures! Let’s Review: Element: pure substance that cannot be separated into simpler substance by physical or chemical means. An atom is the smallest part of an element. Atoms are made of protons, neutrons, and electrons. All things on Earth, except energy, are made of atoms. Scientists will be able to predict where an element falls on the periodic table based on its criteria. Periodic Table How do we know where to put the elements? The elements are arranged based on their atomic number. What is that again? The atomic number is the number of protons in the atom. Scientists will be able to predict where an element falls on the periodic table based on its criteria. Periodic Table What other part of the atom has the same number as protons? There are the same number of protons and electrons in an atom. Scientists will be able to predict where an element falls on the periodic table based on its criteria. Atomic Mass So, we know what the atomic number is. But, what is atomic mass? The atomic mass given in the periodic table is an average of the atomic mass of the isotopes of an element. This is because there can be different numbers of neutrons from protons. Scientists will be able to predict where an element falls on the periodic table based on its criteria. It’s complicated, so let’s practice! In pairs, try to fill out the missing information for the first 20 elements of the periodic table. Then, answer the discussion questions. To get the A+: work together, work hard, stay on task Scientists will be able to predict where an element falls on the periodic table based on its criteria. Share-Out Let’s see how you got your answers for the periodic table chart and the discussion questions. Periodic Table Hunt! Let’s see how much you’ve learned! Try this periodic table hunt with your groups. We will continue this tomorrow. Let’s Bring it Back Scientists will be able to predict where an element falls on the periodic table based on its criteria. How did we do this? Homework: #11 Periodic Practice Fill in the missing information from the periodic table just like you did today during class. Take your in class work home with you for extra help. Ticket to Leave • What stuck with you today? Tell me about something that you thought was interesting or made an impression on you today. Or…ask me a question about something you don’t understand. This will be graded as completed or not once per week. Use the sentence frames on your daily agenda to help you if you need it. Scientist of the Day
