"Does Air Take Up Space?" Water and Air PPT Courseware 2

The status and role of teaching materials

"Does Air Occupy Space?" is the 6th lesson of the "Water and Air" unit in the first volume of the third grade textbook of the textbook. This lesson strives to let students realize that air, like other substances, can occupy space and that air can be compressed through a series of activities. , can also expand and expand. Students' learning in this course acquires knowledge through the experimental process of making experimental conjectures - conducting experiments, verifying conjectures - and drawing conclusions. This can cultivate students' innovative spirit and hands-on practical ability.

teaching objectives

Knowledge and Skills: Air occupies space; air occupies space changes (compression or expansion).

Process and methods: Use experimental methods to confirm that air does occupy space; use methods to compare experimental control conditions to make observations; make predictions and explanations based on scientific facts.

Emotions, attitudes, values: Cultivate good habits of cooperation with others, form a scientific attitude of respecting facts and seeking truth from facts, and stimulate curiosity and thirst for knowledge in learning science.

1. Create situations and introduce topics

The topic is introduced through the story of a crow drinking water and the activity of blowing a balloon.

Does air take up space?

2. Prove through experiments: Air occupies space

1. Students complete the experiments in the textbook independently

(1) Small watering can experiment

(2) "The Adventure of Paper"

2. Teacher conducts experimental demonstration

(1) "The moving ball"

(2) "Water and fire are compatible"

3. Students proved through comparative experiments that the space occupied by air can change

4. Class summary:

Let students summarize what they learned from this lesson

1. Air can also take up space.

2. How much space the air takes up can be changed.

Innovation:

1. Transform abstraction into image, enhancing credibility;

2. Change from being tired of studying to enjoying studying and making it more interesting;

3. Improve experimental results and reduce waste.
