What is the number of protons in carbon? How do you know? What is the number of neutrons in Tin (Sn) – 120? What is something you learned this week? Schulze (Your name) 2/1/16 FAQ: What do I need to write in my notebook? Bold words need to be copied exactly. Italics gives instructions or useful information. This only needs to be copied if it is bold. Elements and Their Properties What: Identify elements How: Elements and Their Properties Lab Why: Get familiar with periodic table. Please continue to read and follow all directions. Launch: Silicon vs. Lead 1. Silicon looks different than lead because . . . 2. An atom of silicon is different than an atom of lead because . . . Class Discussion: Chemistry Unit Introduction Why is a carbon atom different than a sodium atom? In general, what makes atoms of two elements different? Let’s make a list of our thoughts and ideas. Chemistry: The study of matter, of the properties of elements, and how atoms react and combine. Skill Practice: Elements and Their Properties Examine each element substance. Make observations and complete the table. Note: “HCl” stands for Hydrochloric Acid. Element Initial Observations Conducts Electricity Reacts Metal? with HCl Aluminum Copper Iron Magnesium Silicon Sodium Sulfur Zinc Exit Ticket: One thing that I remember about studying chemistry in the past is . . . HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms. Schulze (Your name) 2/2/16 FAQ: What do I need to write in my notebook? Bold words need to be copied exactly. Italics gives instructions or useful information. This only needs to be copied if it is bold. Personal Periodic Table What: Read the periodic table How: Make Personal Periodic Table Why: Spot numbers that identify an element Please continue to read and follow all directions. Launch: Please collect a pretest on reading a square on the periodic table. Complete the pretest to the best of your ability. You are not being graded on this, so don’t stress. Research: Periodic Numbers {Use your cell phone or a computer.} Define the following terms: Atom: Proton: Electron: Neutron: Atomic Number: Atomic Mass: Skill Practice: Personal Periodic Table - Research the squares on the periodic table and write into your own personal periodic table. (Periodic Table Basics) - Use Chem4Kids.com to find all the relevent information. Go to Element List, choose element, “More about orbitals and compounds.” Bohr Diagram is located at the end of More about orbitals page. (If you want, you can search Lewis dot structure.) Note: We will work on more understanding over this unit. Exit Ticket: i. The number of protons in carbon is . . . ii. I know this because . . . HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms. Schulze (Your name) 2/3/16 FAQ: What do I need to write in my notebook? Bold words need to be copied exactly. Italics gives instructions or useful information. This only needs to be copied if it is bold. Neutrons What: Identify differences in atoms How: Calculate neutrons, atomic worksheet Why: Use elements to study matter. Please continue to read and follow all directions. Launch: The number of protons in: a. Carbon: b. Sodium: c. Magnesium: d. Lead: I know this because . . . Class Discussion: Calculating Neutrons - Reminder: Protons determine the type of atom. - Number of neutrons in an atom varies. This is called an isotope. - Mass Number = # of protons + # of neutrons. {See YouTube Videos or Week 21 on Schulze TeacherPage.} Skill Practice: Atomic Worksheet2 - Complete the worksheet based on the periodic table. - # of protons = Atomic Number - # of electrons = # of protons (this is a neutral atom.) - Mass number = # of protons + # of neutrons - # of neutrons = mass number - # of protons (Mass number must be a whole number!!!! You can’t have half a neutron. Use atomic mass and round up.) Exit Ticket: The number of neutrons in Tin-120 are . . . (Note: Tin has the symbol Sn.) HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms. Schulze (Your name) 2/4/16 FAQ: What do I need to write in my notebook? Bold words need to be copied exactly. Italics gives instructions or useful information. This only needs to be copied if it is bold. Aluminum vs. Sulfur What: Explain differences in atoms How: Write to Explain: Sulfur vs. Aluminum Why: Foundation of chemistry Please continue to read and follow all directions. Launch: Comparing two elements. Note: The dots on the circles are electrons! 1. The two atoms are the same because . . . 2. The two atoms are different because . . . Class Discussion: Claim/Evidence/Explanation Claim: Are sulfur and aluminum different? How? Evidence: Which physical properties of sulfur and aluminum are different? Explanation: How are atoms of sulfur and aluminum different? Skill Practice: Writing to Explain. Exit Ticket: Something that I learned this week is . . . A question that I have about chemistry is . . . HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms. Schulze (Your name) 2/5/16 FAQ: What do I need to write in my notebook? Bold words need to be copied exactly. Italics gives instructions or useful information. This only needs to be copied if it is bold. Aluminum vs. Sulfur What: Explain differences in atoms How: Write to Explain: Sulfur vs. Aluminum Why: Foundation of chemistry Please continue to read and follow all directions. Launch: Writing to Explain – Element Comparisons - We started the week by making observations of different pure elements. - These observations, we can see that elements are different. - In the “Support claim with evidence” section, discuss the different physical and chemical properties. - In the “Possible Scientific Explanation”, talk about the different properties of atoms. - You may use other data for top marks. Skill Practice: Worksheet - Complete “A World Famous Table” worksheet (both sides) and turn in. Exit Ticket: Something that I learned this week is . . . A question that I have about chemistry is . . . HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
