Model essay on scientific activities in kindergarten large classes: a useful sieve

moving target

1. Try to understand the function of the sieve and find out the relationship between the size of the sieve hole and the separated object.

2. Interested in adventure activities.

Activities to be prepared

Soybean and sesame mixture, spoon, tweezers, chopsticks, middle hole sieve.

Activity process

First, talk, lead to the topic

1, Teacher: Look, children, there is a pot of soybeans and sesame seeds mixed together.

(Showing the mixture)

Now, I want to separate sesame and soybean. Please think about how to separate soybeans from sesame seeds.

2. Cognitive tools

Display tools: spoon, tweezers, chopsticks, sieve.

You can choose any tool and put the beans and sesame seeds in two bowls to see who can share them quickly and well.

Second, find the role of the sieve.

1, please tell the child how to divide it? Are beans and sesame seeds separate?

2. Let the children talk about how they divide it.

Please use the children in the sieve to demonstrate, and then everyone will try.

Through experiments and comparison, it is found that the sieve can separate the mixture at high speed. )

Third, explore why a sieve can separate things.

1, Question: Do you know why a sieve can separate things?

(Children discuss while operating)

2. Question: What do you think is the advantage of dividing things with a sieve?

The reason why the sieve can separate things is discussed: there are many sieve holes on the sieve, which can leak things smaller than the sieve holes.

Something bigger than the hole is left on it, thus separating the two things. )

Fourthly, find out the relationship between the sieve hole and the size of the separated object.

1. Display: 1 Pot of flour, mixture of mung bean and corn, broad bean and red bean, 3 sieves with different mesh numbers.

Teacher: Can you separate these things with a sieve?

3. Teacher: What sieve do you use to separate rice and flour? Can I use something else? Let's have a try.

The teacher demonstrated the use of a sieve with large holes, and both things leaked out.

4. Discussion: Why?

Let the children find that rice and flour are smaller than the sieve holes, so they all leak down.

5. Teacher: What sieve do you use to separate broad beans from flour? Can I use something else?

The teacher demonstrated using a small hole sieve, and as a result, both things were left on it.

Why is this happening?

Let the children know that you should choose the right sieve to divide things.

Let the children divide these things with a suitable sieve.

Let's see who can get it quickly and accurately.
