Study the structure of the atom with paper plates m&m's! This lab investigation on edible "electrons" and elements explores the Essential Question: How are Elements Arranged in the Periodic Table?
And, How Are Electrons Configured in an Atom?"
Share with your students edible electrons (EX: m&m's, skittles, smarties, cereal, or mini-marshmellows .BE ALERT TO STUDENT’S FOOD ALLERGY WARNINGS! Products may contain nut and other allergens). They will model atoms of elements using a paper plate and different sorts of sweets. At the end of the lab, when Ss have correctly demonstrated their understanding of atomic number and the Bohr model of the atom, Ts may wish to let them eat their model!
This activity has the following lesson objectives. Students will be able to (SWBAT):
• describe the patterns that exist in the electron configurations for the main group elements, such as elements in the periodic table are organized by atomic number.
• relate an element's position in the Periodic Table to the energy level of its valence electrons (excluding transition metals, lanthanides, and actinides).
• explain why there are only two elements in the first row of the Periodic Table.
• identify the columns in the Periodic Table that contain 1) the alkali metals, 2) the alkaline earth metals, 3) the halogens, and 4) the noble gases, and describe the differences between each family's electron configuration.
• given the outermost energy level electron configuration for an element, determine its family on the Periodic Table.
This lab is classroom tested to help students with the following Florida Next Generation Sunshine State Standards in Science. SWBAT
• SC.8.P.8.6 Recognize that elements are grouped in the periodic table according to similarities in their properties.
• SC.8.P.8.7 Explore the scientific theory of atoms (also known as atomic theory) by recognizing that atoms are the smallest unit of an element and are composed of sub-atomic particles (electrons surrounding a nucleus containing protons and neutrons).[CCSS Connections: MACC.K12.MP.4: Model with mathematics].
• SC.912.P.8.3 Explore the scientific theory of atoms (also known as atomic theory) by describing changes in the atomic model over time and why those changes were necessitated by experimental evidence.
• SC.912.P.8.4 Explore the scientific theory of atoms (also known as atomic theory) by describing the structure of atoms in terms of protons, neutrons and electrons, and differentiate among these particles in terms of their mass, electrical charges and locations within the atom.
• SC.912.P.8.5 Relate properties of atoms and their position in the periodic table to the arrangement of their electrons.
