"Interesting and Useful Physics" into the physics PPT courseware

learning target

1. What content should be learned in physics?

2. What are the interesting phenomena in physics?

3. What is the use of physics?

4. How to learn physics well

5. Seven steps of scientific inquiry

1. There are nearly 1,000 people in our school. When does class start and when does get out of class end? How can we tell the difference?

This is one of the important things to learn in physics: sound

Thinking: What other phenomena in our lives are related to sound?

For example, music, cell phone ringtones, teacher’s speech, students hear, firecrackers, etc.

2. Speaking of the sound of firecrackers, it reminds me of the fireworks set off during the Chinese New Year. I guess everyone likes watching colorful fireworks as much as I do. Have you ever thought about why it is so dazzling and dazzling?

This is one of the important things to learn in physics: light

Thinking: In addition to fireworks, what else in life is related to light?

Such as sunlight and lights,

3. Students, do you know the reason why it rains in summer but snows in winter? The strangest thing is that in winter, white mist appears when we breathe?

This is one of the important things to learn in physics: heat

Thinking: What other heat-related phenomena are around us?

For example, the weather is hot, the room is cool with air conditioning, water heater, etc.

Physics is fun

1. The most romantic thing I can think of is to bask in the sun with you. But it’s too OUT to bask on the beach, so let’s bask in the sea slowly together!

2. Fill the glass with water, cover the mouth of the glass with a piece of cardboard, hold it with your hand, and turn it upside down. What will happen after you let go?

3. Slowly turn the mouth of the cup in all directions. What will happen again?

(1) Paper that cannot be blown open (all students participate)

Equipment: paper.

How to do it: Fold a piece of paper in half and tear it in half, fold them together, and blow hard on the center of the two pieces of paper. Students will find that the pieces of paper are close together and do not appear to separate as soon as they blow.

(2) Unable to stand up (all students participate) Equipment: students themselves. Method: Each student has his feet on the ground, his hands on his legs, and his back straight. Requirements: The body cannot lean forward, backward, or sideways. Then, the teacher said "stand up". Students will be surprised to find that when they meet the requirements stated by the teacher, they cannot leave their seats and stand up.

(1) Do ice flowers in winter form on the inner surface or the outer surface of the glass?

(2) When steaming steamed buns, should the upper layer be cooked first or the lower layer?

(3) Some students like to watch the sunrise, so is the fiery red sun we see at sunrise the real sun? How is the rainbow formed after the rain?

(4) When a snowstorm occurs, why do armed police soldiers spread salt on the roads?

(5) Why are there patterns on the surfaces of our shoe soles and tires?

(6) Why are the schoolbag straps so thick?

(7) When we catch fish and shrimp, we first see where the fish and shrimp are, and then reach out to catch them. Can we catch them?

Experience the laws of scientific inquiry

1. Ask questions

Does a magnifying glass always "magnify" the image of an object?

2. Conjecture or hypothesis

Conjecture 1: Always "zoom in".

Conjecture 2: It can both "zoom in" and "zoom out".

3. Design experiments and specify plans

Use a magnifying glass to look at objects at different distances and observe the size of the object's image.

4. Experimental observation and collection of evidence

⑴When you use a magnifying glass to look at nearby objects, the observed image is magnified.

⑵ When looking at distant objects with a magnifying glass, the observed image is reduced.

5. Analysis and demonstration (summary and conclusion)

The image formed by a magnifying glass can be either "enlarged" or "reduced". That is to say, conjecture 2 is correct.

6. Evaluation

7. Communication and cooperation

The above are some of our methods of learning physics.
