Objectives

Students will be able to...

1. Describe some of the experiments that led to the current atomic theory.

2. Compare the different models of the atom.

3. Explain how the atomic theory has changed as scientists have discovered new information about the atom.

4. Create a timeline that will describe the development of the Atomic Theory.

1 HOOK/ATTENTION GETTER

THE TEACHER WILL:

1. Play the Atomic Theory song as students are entering the classroom.

2. Let the song play through.

3. Ask the students what the song was about. Allow for students to brainstorm for a minute or two about the song.

4. Write down any information that the students could recall from the song on the board.

Student Instructions

THE STUDENT WILL:

1. Listen to the song playing upon entering the room.

2. Brainstorm for a minute or two about the song.

3. Discuss what the song was about

2 DIRECT INSTRUCTION

Activity: Reading

THE TEACHER WILL:

1. Group students into their activity groups (pre-determined).

2. Pass out an Atomic Theory book to each group (books were prepared ahead of time by teacher).

3. Explain to students that the books include information about the development of the atomic theory (contributors, dates, models, experiments that pertain to each model and any other important contributions to the models).

Student Instructions

THE STUDENT WILL:

1. Read through the Atomic Theory books.

3 GUIDED PRACTICE

Popplet
Free, Paid

THE TEACHER WILL:

1. Pass out ipads (one to each group).

2. Instruct students to log in to their Popplet site and design a mindmap of the development of the atomic theory using the information from the Atomic Theory book and song.

3. Explain that this is to organize their thought process for their timeline.

4. Inform the student that this Popplet is to be a BASIC mindmap.

5. Instruct the student to email the link of the completed mindmap to the teacher and raise their hand for the teacher to visually check their Popplet.

6. MONITOR the students group work.

Student Instructions

THE STUDENT WILL:

1. Create a BASIC mindmap using Popplet to organize their thought process in preparation for the design of their atomic theory timeline.

2. Email the link of the finished Popplet to the teacher AND bring their iPad to the teacher to show them that their map is complete.

4 INDEPENDENT PRACTICE

Tiki-Toki
Free, Paid

THE TEACHER WILL:

1. Instruct the student groups to proceed to Tiki-Toki.

2. Explain to the student that they are to create a web-based interactive timeline on the development of the atomic theory.

3. Inform the groups that they are to include the following information for each model: dates, the contributor (name and picture), picture or video of model, list any major contributions made during that time frame relating to the model and explain any experiments that helped develop that particular model. They may use text, pictures, videos, etc. throughout their timeline.

Student Instructions

THE STUDENT WILL:

1. Use Tiki-Toki to design a timeline showing the development of the atomic theory. One timeline/group.

2. Include the following information for each model: dates, the contributor(name and pic), picture or video of model, list any major contributions made during the time frame relating to the model and explain any experiments that helped develop that particular model.

3. Email the link of the completed timeline to your teacher.

5 WRAP-UP

THE TEACHER WILL:

1. Prepare a quick 5 question exit quiz with the app Kahoot. This should be done ahead of time.

2. Give the student groups the Kahoot code to the quiz so they can join in a team competition by taking a quiz on Kahoot.

3. Start the quiz once everyone is logged in.

4. Display the quiz results on the smartboard for immediate feedback.

5. Note if any groups are having difficulty.

Student Instructions

THE STUDENT WILL:

1. Take a 5 question quiz with the kahoot app as a team. The teacher will provide students with a code so they can log on to the quiz.

2. View the results on the smartboard for immediate feedback. This will be a team competition.
