Teachers should let students talk about the contents and methods of scientific learning and ask questions of scientific interest. The following is a draft of scientific activities in the first grade of primary school, which I compiled, hoping to provide you with reference and reference.

Lecture notes on scientific activities in the first grade of primary school: let's talk about observation first.

First, the teaching objectives

1. Scientific knowledge

Understand the functions of various senses and the characteristics of watermelon.

2. Scientific inquiry

Using multiple senses to observe watermelon from multiple angles, we can choose the appropriate sensory observation according to the observation purpose, and describe the observation process and results.

3. Scientific attitude, STSE

Recognize the great significance of observation in scientific inquiry and learn the persistent research spirit of scientists. Initially establish a sense of protecting yourself and others' senses.

Second, teaching preparation.

Grouping materials: watermelon (whole and half cut), wet tissue, plastic fork or toothpick, small plate.

Teacher's preparation: fruit knife, chopping block.

Iii. Teaching time 1 class hour

Fourth, the teaching process

(A) Teaching introduction

The teacher showed the watermelon and put forward the learning task: learning science. Let's talk about observation first. First of all, let's take watermelon as an example to learn how to observe.

(b) New lessons learned

1. Overall observation of watermelon

(1) Distribution materials: each group 1 complete watermelon.

(2) Guide students to observe with eyes, nose, hands, hands and ears in groups.

(3) The findings after communication and observation. For example, the shape, color and pattern of watermelon, the sound when flapping, etc.

2. Continue to observe watermelons from outside to inside.

(1) Distribution material: each group 1 watermelon cut in half in advance.

(2) Each group continued to observe from outside to inside.

Teachers patrol to guide students to combine senses, functions and discoverable watermelon features (such as eyes-vision-shape, size, color and pattern; Handle-smoothness and hardness; Ear-hearing-sound; Nose-smell-smell; Tongue-taste-taste) and so on.

3. Taste watermelon and describe the taste (tongue-taste-taste)

4. Summary

Say: What is watermelon like? How do we know?

Only by observing different aspects of watermelon with various senses can we have a more complete understanding of watermelon.

Discussion expansion

Besides helping us observe all aspects of watermelon, what else does the senses help us discover in our daily life?

Protect your senses.

(1) Identify which behaviors are harmful to sensory health.

(2) Summarize the methods to protect the senses correctly.

(3) Tell the observation story of Fabres. Sort out the information, class is over.

Teaching objectives

I. Scientific knowledge

1, can tell the contents and methods of science learning.

Second, scientific inquiry.

1, you can ask questions about science.

2. Be able to make assumptions about the result of paper blowing.

3, can use language to describe the observation results.

4. Be able to discuss and exchange your findings with your classmates.

Third, scientific attitude.

1, can show a strong interest in the content of science class.

2, can truthfully describe the observed phenomenon.

3. Be able to share and communicate with others and conduct cooperative learning.

Teaching preparation

First, the teacher prepares: video courseware A4 paper, a pair of scissors and a ruler.

Pictures or videos of scientific phenomena and experiments related to this lesson. Teachers can prepare information in different fields, such as the earth and the universe, life, materials, engineering and technology, so that students can understand science in all directions.

Second, teachers and students prepare together.

A piece of A4 paper, two pieces of paper, a pair of scissors and a ruler.

teaching process

First, situational introduction. When it comes to science, what do we think of?

Among the students, we will learn a science class from the first year of high school, and we will walk into science together. "When it comes to science, what do we think?"

Use brainstorming to let students communicate fully and speak boldly. Give students a sense of psychological security.

Listen to the students.

Look at the pictures in the textbook. Ask students freely: Why do flowers have all kinds of colors? How is the rain formed? Why do balloons float in the air? How can the train run faster?

Look at the pictures in the textbook. Let students understand that science is all-encompassing, and science is all around us. Scientific learning begins with discovery and questioning.

Second, blow air between two sheets of paper

1, situation introduction Just now, the students mentioned that studying science will do all kinds of interesting experiments. Let's start our scientific journey, walk into the door of science together, do research and experience the mystery and magic of science.

2. Ask a question: What happens when you blow air between two sheets of paper?

3. Make assumptions.

4. Experimental verification. Do it in pairs, one does the experiment and the other takes notes. Switch roles and repeat the experiment. Description of experimental method: First, put two pieces of paper vertically and stand still. Don't walk around beside your classmates, and don't be disturbed by factors such as electric fans. First observe the state of the paper at rest, and then blow hard into the middle of the paper to observe the changes of the paper.

5. Experimental conclusion: Through the experiment, it is concluded that the paper will move closer to the middle.

6. Expression and communication. Communicate with classmates. Briefly describe the experimental process.

7. Reflection and evaluation. Let the students talk about their feelings about the experiment.

Third, the origami plane.

1, the work is leading. The teacher first shows the finished plane to stimulate students' interest. Tell the students that we are going to make a paper plane.

2. master the method. Open the activity manual to observe the folding method of the paper plane, and then fold the paper plane according to the above method.

3. Technical practice. Let the student animals origami the plane. Teachers patrol.

4. Exchange evaluation. Share your successful experience and reflect on the reasons for your failure. Self-evaluation and others' evaluation.

5. Technical improvement. How to fly far and fly higher?

Model essay on scientific activities in the first grade of primary school: going into nature

Teaching goal 1, let students go into nature, know nature and even fall in love with nature.

2. Cultivate students' ability of observation and expression.

3. Let the students have a preliminary understanding of the content involved in this lesson.

4. Cultivate students' interests and hobbies in this subject.

Teaching focuses on making students fall in love with this subject.

The difficulty in teaching is how to make students fall in love with this subject.
