#### 1 HOOK/ATTENTION GETTER

• ​How does heat move?
• High Level: Discuss how heat moves in a room with a radiator and a fan on the roof.

Student Instructions

Students will activate their background knowledge of how heat moves from hot objects to cooler objects / Hotter molecules to cooler ones.  This was discussed in the previous class.  Additionally, for differentiation students that need an added challenge will  Discuss how heat moves in a room with a radiator and a fan on the roof.

#### 2 Introduction of New Material

Before having groups start their videos ask students to provide examples of when they have experienced heat transfer in the real world.  Ask them to think deeper about examples that have more than one form of heat transfer. Encourage debate about the most accurate form of transfer present.

• An example might be: Petting my cat is an example of radiation and conduction, because my cat is radiating heat, but I am not touching the skin of the cat. I am petting/touching the fur.  Therefore there are two forms of heat transfer present.
Student Instructions

Students should make a T-chart in their notebooks to record new information and questions they have about the movie.  Students should be grouped homogeneously to provide the most appropriate movie.

Students will watch the movies in their own groups using laptops.

After the video students will share their new understandings and questions.

#### 3 Instruction

Activity: Presenting

Give students a note-catcher to collect the collaborative information gained from the video.

• Students should come away with the following in their note catchers:

waves which directly transport heat
energy through space.

Convection: Convection is the transfer of
heat energy through a gas or liquid by
movement of currents.

Conduction: Conduction is the transfer of
energy through solid matter from particle to
particle.

Student Instructions

Students share their evidence they collect from the video.

Connect- Extend- Challenge discussion protocol is to get students to the definition of Conduction, Convection and Radiation.

#### 4 INDEPENDENT PRACTICE

Teacher will provide the students with the task to present one form of heat transfer using the Tellagami App on their phone.   Students will upload their projects to their Google Drive and to Google Classroom to share with the teacher and class.

Student Instructions

Your task:  Make a Tellagami video of your assigned form of heat transfer.  Make sure you discuss the forms of heat transfer that are present and answer the questions from your task card and upload an illustration you find from a Google Search to your Drive and to our Google Classroom Website.
