Name: Jennifer Kirby
Subject: Biology
Period: 1st (50 minutes)
Date: 06/11/09
Objectives:
The student will…
a. describe the particles that compose atoms and elements (including protons,
neutrons, electrons). DOK 1 (MS 2.b)
b. recognize element names from their symbols and formulate element symbols
from their names. DOK 1 and 3 (MS 2.b)
c. recognize which elements are metals and nonmetals using the periodic table.
DOK 1 (MS 2.b)
Materials:
Styrofoam balls of varying sizes and colors, toothpicks, markers/crayons, Notes
worksheet, Periodic Table, Element/Symbol Periodic Table worksheet, Stickers, Red and
Blue marker/crayon, Laptop and LCD projector for video, Quiz
Bellwork: (3 minutes)
List the seven characteristics of living things: cellular organization, reproduction,
homeostasis, growth, reacts to changes in environment, uses energy, genetic code
Set: (5 minutes)
1. TTW ask student to recite the seven characteristics of living things from previous
day’s lesson. Upon completion of list, TTW state that today’s lesson, unlike
yesterday’s focus on living things, will be focused on a characteristics of all
things, both living and non-living. TTW ask if student can state a characteristic
that all objects share.
2. After revealing the answer, matter and its basic unit (the atom), TTW discuss the
difficulties of understanding the atom because of its small size. To demonstrate
the size of the atom TSW watch a video clip from “Cosmic Voyage.”
3. TTW state the objectives of the period.
Procedures:
A. TTW present a mini-lecture on matter and atoms using a notes worksheet on
which TSW write down definitions of matter and atoms and provide examples
of substances with matter. (This worksheet will have space for the definitions
of the remaining vocabulary words for the period). (4 minutes).
B. TTW transition to a hands-on demo of the atom and the composition of the
atom with Styrofoam balls of different colors and sizes. TSW fill out the
worksheet with table of atom parts and diagram (6 minutes).
C. TTW give a verbal quiz on the charge and location of protons, neutrons, and
electrons with models (1 minute).
D. TTW describe the connection between atoms and elements. TSW record the
definition of an element and the number of elements. TTW ask if student can
give examples of elements? And in what substances common elements are
found? (5 minutes).
E. TTW gives the student a copy of the periodic table to demonstrate how many
elements there are and how element symbols are written. The teacher will ask
what the student thinks the symbol for Carbon, Oxygen, and Sodium are?
TTW say that sometimes the symbol is not what we might expect, the symbol
for Sodium is based from the latin word for sodium (or salt) = natrium (3
minutes).
F. TTW demonstrate how scientists organize the elements on the table using the
atomic number (protons) starting with the elements with the fewest protons
(H) to the most protons (Lr – Lawrencium). TTW ask student to name the
symbols of elements using certain atomic numbers (3 minutes).
G. TTW ask the student “What are the most common elements?”; Leading
student to answer by asking what makes up air and water. TTW teach student
the most common elements in nature using a mnemonic device: CHONPS (4
minutes).
H. TSW practice recognizing elements by their name, symbol, and location on
the periodic table using a periodic table worksheet. TSW put stickers on the
elements, atomic number, or symbols on the table when the teacher calls out
the reference element or symbol. (6 minutes).
I. TTW ask if student can, using his previous knowledge about certain elements,
point out where most metals and non-metals are found on the table. TTW ask
student to write down 3 metals and 3 non-metals. TTW show the student how
the Periodic table is divided into metals, non-metals. (3 minutes).
Closure:
1. TTW review the material (objectives) covered by asking student to name 4
important things he/she learned today (1).
2. TTW assess using a short matching and coloring/charge quiz that the student will
turn in when the bell rings (or if we run out of time – take-home quiz to turn in
tomorrow) (6 minutes).
Assessment/Evaluation:
Objective 1: TSW describe the particles that compose atoms and elements (including
protons, neutrons, electrons).
Informal Assessment: TTW listen to the student (M) describe the composition of
an atom (C).
Formal Assessment: TTW grade students quiz (M) to determine if student
knows the composition of an atom (C) and record the grade in the grade book (D).
Objective 2: TSW recognize element names from their symbols and formulate element
symbols from their names.
Informal Assessment: TTW observe the student’s responses (M) on the class
worksheets to determine if the student can recognize elements and formulate element
symbols (C).
Formal Assessment: TTW grade students quiz (M) to determine if student
knows can formulate symbols (C) and record the grade in the grade book (D).
Objective 3: TSW recognize which elements are metals and nonmetals using the periodic
table.
Formal Assessment: TTW grade students quiz (M) to determine if student can
distinguish which elements are metals and non-metals (C) and record the grade in the
grade book (D).
