Large class rocket science activities 1 teaching plan teaching objectives;
1, understand the basic structure of the rocket, and explore the size relationship between the cylindrical arrow body and the conical rocket head.
2. Perceive the reasons for the rocket's lift-off, and boldly try to analyze various factors of the rocket's rise.
3. Try to make rockets with various materials, cultivate children's hands-on and imagination ability, and stimulate children's interest in exploring aviation knowledge.
4. Actively share and communicate your findings with your peers.
5. Cultivate children's interest in exploring scientific phenomena.
Teaching preparation:
1. Children's interest in rockets and their preliminary understanding.
2. Rocket models, bottles, cardboard, lead drawing paper, crayons, post-it notes, scissors, glue, double-sided tape, etc. Children's collection.
3. Multimedia courseware "Rocket to Heaven"
Teaching emphases and difficulties:
Focus: Explore the size of the interface between the cylindrical arrow body and the conical rocket head, and try to make a small rocket.
Difficulties: the manufacture of rocket head and the pasting of various parts, exploring ways to make small rockets fly high.
Teaching process:
First, ask questions into the theme to stimulate children's interest
1, Question introduction: Have you ever seen a rocket? Where have you seen it? What is the rocket you have seen? Stimulate children's interest in learning.
2. Look at the courseware. The teacher discusses the topic of Shenzhou VII with you. The children know that the successful launch of Shenzhou VII is due to the technology of small rockets. Do children want to fly into space like pilots? Let's design and manufacture our own small rockets, shall we?
Second, observe and discuss, explore production methods, and learn to make space rockets.
1. Look at the second half of the courseware and talk about the main structure of the rocket. Teacher: What does a rocket look like? How was it introduced? Do you want to design a rocket that can fly into the sky?
2. The teacher demonstrated the production and the children tried to design and produce it. Teacher, there is a small rocket here, too. See how it's made. The teacher turned the square paper into a cylindrical arrow and the semi-circular paper into a conical rocket head; Let the arrow body and the rocket head fall in love.
Who will try to make a cylindrical arrow body and a conical rocket head? Please try individual children. The manufacturing method of rocket head is emphatically introduced.
4. Children choose materials to make according to their own wishes, and teachers tour to guide them to paste and combine to make rocket heads. Focus on helping children with weak abilities.
Remind children to pay attention to good operating habits and hygiene habits. Praise creative children in time and help children in difficulty appropriately.
Third, show communication and explore ways to make small rockets fly high.
1, children show their homemade rockets, and visit them together. Please introduce them to individual children. The children who finished first went outside and tried how to launch a small rocket into the sky with the help of a launcher.
2. Back to class, please introduce the experiences of individual children to see whose rockets fly high, and further stimulate children's interest in exploring aviation knowledge. Teacher: How did you get a small rocket into the sky? (clap hard with your hand). Why can a small rocket fly into the sky with a hard beat? What else did you find when you were playing just now? (Sometimes fly high, sometimes fly low)
3. Do our children still want to play? At this time, you can compare with your good friends when you fly high and when you fly low. Why? Push hard, the bottle is big, pat the bottom of the launcher, and the rocket made of cardboard flies high.
4. Launch small rockets collectively to let children experience the happiness of success.
Let's go to the launch pad to see who designed the small rocket carrying shenzhou spaceship to fly the highest.
Countdown: 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, ignite!
Teaching reflection:
The "Outline" points out that science education should be closely linked with children's real life and make use of things around them as the objects of scientific exploration. So I chose "Rocket Up to the Sky" as the content of children's science education. Children in large classes are more eager to explore, like to do things, like to think, and dare to guess. At the same time, they have accumulated some experience in air perception and will express their knowledge and feelings in their favorite way. To this end, I provide children with ample opportunities to explore, and cultivate their ability to explore records by guiding them to predict, explore, record and verify.
Large class scientific activities rocket teaching plan 2 activity objectives:
1. Explore the method of using the power of air propulsion to realize the flight of "small rocket".
2. Understand the relationship between launch height and launch intensity of "small rocket" through operation, recording and comparison.
3. Stimulate the interest and desire of scientific exploration.
Activity preparation:
1. knowledge and experience preparation: I learned the relevant knowledge and experience of rocket flying into the sky.
2. Material preparation: 5 height reference ladders; A few small rocket toys; 1 large record form; 1 small record sheet and pen holder.
Activity flow:
First of all, watch the scene of the rocket ascending to heaven and mobilize knowledge and experience.
Teachers and students watched the moving scene of "Shenzhou IX" ascending to heaven together, and carefully observed the appearance characteristics and launch mode of Shenzhou IX.
Q: Do you know how many parts a rocket consists of? Which two parts?
Second, explore the principle of rocket lifting and explore the operation.
1. Watch the toys and learn about the materials for making the "rocket".
Teacher: Today, the teacher also brought you toy rockets.
Question: What material is it made of? What part of the Sprite bottle looks like a rocket? What's a paper hat like?
Summary: It turns out that toy rockets are made of sprite bottles and paper caps, representing rocket launchers and rocket heads respectively.
2. Operate independently and explore the method of "rocket" flight.
Teacher: The toy rocket has a wish. It also wants to fly. Are you willing to help it?
Question: Think about how to make a toy rocket fly. (Children guess at random) Have fun and try to make the rocket fly.
Communication games.
3. Discuss and summarize the principle of "rocket" flight.
Teacher: Whose method do you think is good? Why did the "little rocket" fly into the sky like this? (Initiate a discussion) Feel the existence of air through demonstration.
Further explore the method of using the power of air propulsion to fly a "small rocket" (free exploration) and concentrate on communication (understanding the diversity of methods)
Third, think deeply, explore again and experience scientific principles.
1. Ask questions and make people think.
2. Record while operating, and the teacher will tour to guide.
3. Focus on the analysis of the relationship between launch height and launch intensity of "small rocket".
Fourth, activity summary and emotional sublimation.
You are a group of clever chinese baby. There are still many scientific secrets hidden in "Little Rocket". When we grow up, we will explore the mystery of rockets like those great scientists.
Large class scientific activities rocket teaching plan 3 goal:
1, to stimulate children's interest in scientific exploration and cultivate children's spirit of scientific exploration.
2. Try to explore the relationship between the height of the small rocket and the force when flapping the bottle.
Prepare:
Children are familiar with the "small rocket March" before class; Have a certain understanding of air; A small rocket; One record form for each person; Hang the sun, the moon and the clouds; Tape recorder, magnetic tape.
Process:
First, explore the method of small rocket to heaven:
1, let children freely try the method of rocket to heaven.
2. Children demonstrate the method of small rockets going to heaven.
3. Children's verification experiment.
4. Q: How do you get the rocket into the sky?
Which method do you prefer? Why?
Second, explore the reasons why small rockets go to heaven:
1, asking questions makes children think.
2. Why can a small rocket fly by flapping a bottle?
3. Let the child cover the bottle cap and then pat the bottle hard.
4. Can the small rocket still fly? Why?
5. Discussion: Why can't the bottle cap fly?
Third, explore the relationship between the launching height of small rockets and the bottle-making force.
1, let the children compare whose little rocket flies higher.
2. Asking questions triggers children's thinking.
Where can your little rocket fly?
Why do some small rockets fly high and some fly low?
Please pat the bottle with different strength, observe the launching height of the small rocket, and record it on the table.
4. Summary: Under the same conditions, the greater the strength of beating the bottle, the higher the rocket flies.
