The Chemistry Unit Chapters include: The development of the Atomic Theory. The periodic Table and the Atomic Structure. Learning objective Current teaching what will students be design able to do? What I normally do in the classroom setting Ch. 1: Lesson 1. Discuss how Students will be able scientist from the to describe: how are 440 BC had find scientists thought of out that matter matters. can be cut or divided into smallest particles. Explain the root word of atom which is Greek meaning Indivisible. Classroom activities that is normally done in the classroom Have students break a piece of chalk to the smallest (finest particles) possible. Ask if they think that it can be divided any further. Lesson 2. The students will learn the progress of the atomic theory from the time of Democritus to the Modern Atomic theory. Bohr idea that the exact path of an electron cannot be predicted. Students will infer using the class activity that according to the current theory, there are regions inside the atom that are called electron clouds. Students will be encouraged to continue thinking about the atom and how may science Create line graph on the board list the scientist on the bottom and their theory of the development on the top of the line. Complete a class activity to show the scatter of the electrons on plain glue covered paper using beans dropped from a cone. This idea, which states the exact path of Discuss the progress of the atomic theory over from the time of Democritus to The Modern Atomic Theory. Explained the nature of electrons in the atom. For example, electrons do not travel in definite paths as Bohr suggested. In fact, the exact path of an electron cannot be predicted. According to the current theory, there are regions Online teaching activities Tools I will use to supplement online activities Have the students watch the YouTube video on the history of the atomic theory. After watching a youtube video about the development of the atomic theory that I found doing a Google search. I was able to find an ok 2.37 minutes video that lists the scientists and their ideas. However, the URL covers this whole page. The students will complete a homework assignment of making a list or a Venn diagram to show the differences of each theory. They can refer to their text if they need to. The students will be making a time line of the scientists who developed the modern atomic theory using www.timetoast.com. Student will have to follow a rubric that will accommodate all levels. Also if the students have access to the computer lab then they can collaborate on this assignment. develop to change the theory. inside the atom where electrons are likely to be found. These regions are called electron clouds. Lesson 3 Students will be able to determine the following: Element have the same number of protons in the nucleus. Isotopes of an element differ by the number of neutrons in the nucleus. Atomic mass is an average of the masses of all of the naturally occurring isotopes of an element. Draw the simplest atom of hydrogen. Label the Proton positive charge inside the nucleus. The electron negative outside. electrons cannot be predicted. Rather, they are in a region inside the atom called electron clouds will be observed. Students follow by making another similar diagram, but they add one more proton and electron to this atom. They will determine that this new element is not hydrogen, but helium. Students usually work in groups of two to create 3D atoms with atomic # of at least 5 they name them according to their atomic number. Using food items or any recallable material. They will be watching students made Youtube videos that are similar to this activity afterward. Assessment CH 11: Ch. 12. Lesson 1. Students will determine: Elements are arranged in order of increasing atomic number. Students use paint on PC in the computer lab to illustrate their own “Atom”. Students should then be told to check the name of the element they made and label all parts. An alternative to this assignment is to make the youtube video using www.animoto.com of their completed 3D atom. This will be suggested if the students can do as part of computer class for the sake of time. Students will complete and upload their video and share it. Have students check the periodic table graph in their book. Have them check all the component of Have the students use a blank black and white template of the periodic table. Students will be using the NSF website to study the different elements. Students will Have students use the NSF website http://genesismission.jpl.nasa.go v/educate/scimodule/cosmic/pta ble.html To use the simulator to build all the different elements using the Elements on the periodic table are classified as metals, nonmetals, or metalloids. Elements in a horizontal row periods, which are listed in order of increasing atomic number. Elements in a vertical column, or groups, which have similar chemical properties. The periodic law states that the properties of elements form a pattern according to increasing atomic number. Assessment Ch. 12 the graph. Starting with the1st column. Students will continue filling and coloring all the groups on this paper as we continue this lesson. Students have to save it in a clear plastic in their binder to be graded. Students will complete the grid. list elements that have similar chemical properties that are grouped in columns properties to group the elements. An alternative assignment/ assessment that can be used as a quiz is to have the students use the virtual lab on https://www.sascurriculumpath ways.com They have to go over the activity and complete the questions and print out the completed lab to be graded as lab assignment. Students will generate a complete list by filling the missing element online.
