Floating and sinking

Class: IV                  Subject: Science

Topic: Floating and Sinking

Lesson objectives: By the end of the lesson, a child should be able to:

1. define floating and sinking in their own words.
2. observe and classify objects that float or sink in water.
3. discuss why some objects float and some objects sink in water.

This is an animated video that will attract students and make learning fun. Students tend to remember more colorful pictures. Teachers sometimes can download videos related to topics that they want to teach in the class. By showing something different students will also feel more interested to learn.

This video has been downloaded from YouTube. For that first watch the video on the topic which you want to teach and select the appropriate video. 

Activity1

•   You will need a bucket of water. 
• Collect some small objects that you find in and around your classroom. Some of the objects are shown in Figure 1.3(a). 
•  Predict whether the objects float or sink in water and write your prediction after copying table 1.5. Now, put them in water one at a time as shown in Figure 1.3(b).

Observe whether they float or sink in water and record your observation in table 1.5. 

Why do some objects float? 

Why do some objects sink?

Activity 2

• Design and carry out an experiment to find whether an object filled with air floats or sinks. 
• Write about your experiment and include the followings: what you needed. what you did. what you observed. what are the variables you have identified?
• After you are done with the experiment you will go to this link https://padlet.com/yangkhillhaden777/go6udaobfgcjye9l 
• Title is already given as objects filled with air float or sink?
• It is a padlet, you can type your answer there. 

Rotation of the Earth

 

 

This video is about how the rotation of Earthworks.  Firstly I downloaded three videos from Vid Made then cropped and made them into one with the app crop video.

Class: IV

Subject: Science

Topic: Rotation of the Earth

lesson Objectives: by the end of the lesson, a child should be able to:

1.  tell that our earth rotates on its axis 
2. write the causes of the rotation of the earth

Activity 

Students will create a simulation to show the rotation of the earth on its axis. 

For that go to PowerPoint Presentation

Use the necessary clipart, shapes, and pictures to make it lively

You can also use animations to make your earth move.

You can explain how your earth's rotation works with a voice-over or with a text.
