The secret teaching plan of the scientific soil big class 1 activity target;
1, experience the fun of exploring the soil, and cultivate the inquiry spirit of careful observation and serious thinking.
2. Try to use various tools to explore the components in the soil, and cultivate hands-on operation ability and observation and comparison ability.
3. Through observation and experiment, different particles in the soil are separated by various tools to find water and air in the soil.
4. Cultivate children's curiosity about things and be willing to explore and experiment boldly.
5. Cultivate interest in exploring nature.
Activity preparation:
1, knowledge and experience preparation: children have mastered the method of separating different substances and the experience of feeling the existence of air through games, operations and experiments.
2. Teacher's preparation: dry soil, a small spoon, a sieve made of disposable paper cups (with different hole sizes), a stirring rod, a paper dish (indicating large, medium and small), a measuring cup, toilet paper and a transparent water cup.
Activity flow:
1, organize children to talk: the soil I have seen.
Teacher's question: Children have collected all kinds of soil in different places. What do you find in the soil?
2. Guide the children to observe the dry soil and find that the particle size in the soil is different.
(1) Teacher's question: Please take a closer look. Are the particles in these soils the same size?
(2) Guide children to discuss: How can we separate these particles of different sizes?
3. Guide children to separate particles of different sizes in the soil in different ways.
(1) Take a look: What tools are there on the desk?
(2) think about it: how to use it?
(3) Hands-on: In soothing music, divide the children into three groups and separate soil particles with small spoons, sieves and water.
(4) Say: Guide children to tell their own operating methods and steps.
(5) Comparison: Which method is the best? Why? Guide children to compare the speed and quality of operation.
4. Guide children to think about how to explore the invisible things in the soil.
(1) Guide the children to discuss: What are the invisible secrets in the soil?
(2) Think about it: How did these secrets in the soil unfold before us?
(3) Give it a try: provide water and paper towels to encourage children to explore the secrets in the soil. Focus on guiding children to observe changes and think about reasons.
5. Teacher-child discussion: What's the secret in the soil? How to discover these secrets?
Activity reflection:
According to the large class, children are active in thinking and have a wide range of interests, and they are particularly interested in the knowledge of natural science. So I chose the topic of "soil", the home of plants. It is used for children to operate experimental activities. The initial plant growth cannot be separated from sunlight and soil. Focus on understanding that there is water, air and fertilizer in the soil, and the growth of plants cannot be separated from the soil. Cultivate children's ability to observe things, think and solve problems, and experience the fun of scientific activities.
Design idea of large class science soil secret lesson plan 2;
This activity comes from the unified textbook (under the middle class) scientific activity "The Secret of the Soil". In this activity, our class's scientific project "magic land" is in the second stage, that is, "the relationship between soil and animals and plants" Before that, we had already carried out the activity of "the first stage: the types of soil", and children had a certain understanding of the types of soil through activities such as collection, observation and classification.
The primary task of children's science education is to stimulate children's curiosity, cognitive interest and desire to explore things around them. The object of this activity: soil, which attracts children. In their eyes, the soil everywhere is so magical and mysterious. What is in the soil? Why can plants and animals live in it? Therefore, we combine the theme of "gadgets are of great use" and design and carry out this activity according to the age characteristics and knowledge and experience accumulation of children in our class, aiming at leading children to explore the secrets of soil and enter the magical soil world through observation, comparison and operation activities. At the same time, through the exploration of soil, guide children to build a continuous, systematic and independent knowledge learning system, and lay the foundation for children's future experience acquisition and knowledge learning.
Activity objectives:
1, experience the fun of exploring the soil, and cultivate the inquiry spirit of careful observation and serious thinking.
2. Try to use various tools to explore the components in the soil, and cultivate hands-on operation ability and observation and comparison ability.
3. Through observation and experiment, different particles in the soil are separated by various tools to find water and air in the soil.

5. Teacher-child discussion: What's the secret in the soil? How to discover these secrets?
Activity tip:
1. The focus of this activity is to use different tools and methods to separate particles of different sizes in the soil and explore things invisible in the soil, such as water and air. Before this activity, children should have the experience of collecting soil and observing soil, and have a certain understanding of the characteristics and types of soil; In addition, children should also master the basic methods of scientific experiments with simple tools, such as screening and stirring. In the activity, teachers should guide children to learn the correct experimental methods and guide them to think about the advantages and disadvantages of different tools and methods.
2. In the process of operation, teachers can provide some tools for making commonly used or discarded materials, such as transparent disposable cups and disposable bowls, as children's operating materials, which can not only turn waste into treasure, but also protect the environment. After the activity, you can also put the operating tools into the activity area, which is convenient for children to operate repeatedly.
3. Organize children to carry out outreach activities: make a small book "The Secret of the Soil" by yourself, and draw your findings in the soil into a book with simple symbols or pictures.
4. Ask parents to cooperate:
(1) Take children to observe the soil around the community and the animals and plants living in the soil.
(2) Take children to know what other ingredients are in the soil.
