SC.912.P.8.4

This is a set of 8 stations (each station lasts 15-20 minutes) that students may complete individually or in small groups. The stations focus on the development of the atomic theory and introduce students to the concept of the subatomic particles, how they were discovered, and where they are located within the atom. The stations can be grouped together and used as one lesson for 2-3 consecutive days, or they can be split into smaller increments and used over the course of several lessons.

Type: Lesson Plan

In this lesson, the 5E model is used to teach students about the structure of an atom. Students will study the atom's subatomic particles, including their masses, electrical charges, and locations.

Type: Lesson Plan

This lesson is designed to be part of a sequence of lessons. It follows CPALMS Resource #52952 "BIOSCOPES Summer Institute 2013 - Solutions." The lesson employs a predict, observe, explain approach along with inquiry-based activities to enhance student understanding of atomic structure.

Type: Lesson Plan

Through this engaging activity students work as a group to create models of isotopes with stickers and construction paper. Students also use models created by their peers to analyze the number of subatomic particles and determine isotopes' names. All worksheets and data collection sheets are included.

Type: Lesson Plan

This lesson allows the students to become familiar with the elements on the periodic table. The students play a game of go fish using cards they've made from index cards. The students match the cards according to their oxidation number in a similar pattern to how the game go fish is played. The students also use the index cards to make flash cards of their elements and use the cards as a study tool. The students will learn how subatomic particles and chemical characteristics determine the placement of elements on the periodic table.

Type: Perspectives Video: Expert

This PBS/NOVA presentation tells the story of the CERN and the Large Hadron Collider project - an amazing ongoing investigation in search of an answer to the mysteries that still exist in particle physics. Recommended discussions and activities before and after the video are provided.

Type: Teaching Idea

Students determine the number of protons, electrons, neutrons, and nucleons for different atoms

Type: Video/Audio/Animation

A collection of crossword puzzles that test the knowledge of students about some of the terms, processes, and classifications covered in science topics

Type: Video/Audio/Animation

Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!

Type: Virtual Manipulative

I use this simulation as an introduction to molecules and compounds to help students understand that atoms are not randomly joined to form a compound/molecule, but join in very specific patterns. In order to successfully complete the simulation activity, students must re-arrange molecules various ways. (In CH3COOH, both oxygens are bonded to the carbon atom, for example)
