Gravitational Energy - Section 2: Gravity at Work

Some of my students are more excited about being outside then with the discussion. For some students this change of venue might be hard for them to focus on the lesson concept. To make sure that these students do understand, I try to talk to each of these students individually to explain why we are using the slide to learn. This individual time is usually all that is needed. We can talk about the concept and then take part in the fun activity afterward. For one student, I talked about gravitational energy before he slid. When he finished sliding, I asked him what helped him slide down. He could not remember what we talked about so we went over gravitational energy again. I then let him slide again after he explained what it was to me. When he came to the bottom this time he understood that gravity was helping making the slide fun.

# Gravitational Energy

Lesson 7 of 13

## Objective: SWBAT develop and explain a model that demonstrates gravitational energy.

#### Fluency and Notetaking

*15 min*

As a grade level we purchased the Scholastic True Book on Energy. To begin this lesson we are going to read a section on gravitational energy. The two paragraphs describe gravitational energy and use examples that students can understand based on playing. Before we read, I hand out two sticky notes to each student. Students are going to practice writing notes as they read. I will model with the first paragraph how to use the sticky to write the most important details on. Students will then practice with the second paragraph the note taking skill.

#### Gravity at Work

*5 min*

To see gravity at work we are going to head to the playground. Students are going to use the slide and swings to see, feel, and use gravitational energy. I have half my students line up to use the slide and the other half stay down at the bottom with me. The group that is with me will discuss as the others use the slide what we now know about gravitational energy. The groups will switch and the same discussion will occur with the second group. We will then move to the swings and discuss gravitational energy when swinging. If there is time I will let students swing, but if not a couple student models will work well to have discuss what we are seeing and how gravity helps us play.

#### Gravitational Model

*15 min*

When we return to class I separate students into groups of three. Students are only allowed to use the materials in their desks to create a model that uses and demonstrated gravitational energy. Before they begin I ask if there are questions in what gravitational energy is. The class is confident and I ask them to work together to create a model. Once the groups agrees on a model, and tests it they can call me over to check it. Once every group has successfully made a model, each group will share there's with the class.
