Middle School Science

1st period

Atoms, Ions, and Molecules:

Approximate Time: 100 minutes

Objectives:

1.(DOK 2 Science 8.8b)TSW take a quiz on periodic table, and subatomic particles

2.(DOK 2 Science 8.8d)TSW distinguish between atoms, ions, and molecules in an in-class assignment

Materials:

construction paper

dry erase markers

handouts

Set:Last time we talked about elements, the periodic table and the subatomic particles. Today we are going to dig a little deeper into atoms as well as introduce ions and molecules.

Procedure:

1.TSW complete the bell-ringer question. (5 minutes)

The 3 subatomic particles discussed last time are____,_____,______

How many protons are in this element?

How many neutrons?

How many electrons?

2.Set:Last time we talked about elements, the periodic table and the subatomic particles. Today we are going to dig a little deeper into atoms as well as introduce ions and molecules.(2 minutes)

3.TSW complete a model atom using construction paper showing the position of protons, neutrons, and electrons in the cell(3 minutes)

4.TSW use construction paper to match definitions with the subatomic particles(3 minutes)

5.TSW use construction paper to match mass number and atomic number definitions(3 minutes)

6.TSW answer cold-calling questions on mass number, atomic number, and the subatomic paricles, groups and periods(5 minutes)

7.TSW take a quiz on the subatomic particles and periodic table (7 minutes)

8.TTW lead class notes on molecules, ions, and atoms(10 minutes)

9.TSW use construction paper to group atoms, ions, and molecules(10 minutes)

10.TSW complete an in class assignment distinguishing atoms, ions, and molecules(15 minutes)

11.TTW lead notes on incorporating ions into the periodic table(15 minutes)

12.TSW use notes to match ions to make molecules(8 minutes

13.TSW create help sheet with atom, ion, and molecule(10 minutes)

9.Closure-Today we reviewed the atom and the location of the subatomic particles within atoms, what are the 3 subatomic particles again?. We also discussed scenarios when there are unequal number of protons and electrons(charged atoms known as ions).We also talked about when two or more atoms bind together to form molecules. Next time we will talk about acids and bases(5 minutes)

Assessment:

Objective 1)

Informal:TSW answer cold-calling questions on periodic table

Formal:TSW match definitions in an in-class assignment(M) about the vocabulary words(C) discussed in class, grades will be recorded in the grade book(D)

Objective 2)

Informal:TSW play matching game at the board

Formal:TSW will complete in class assignment questions(M) on distinguishing between ions, atoms, and molecules(C) which will be recorded in the gradebook(D)
