Today Little Fish Brother shares with you the observation lesson for toddler class: how the salt disappeared.

Objectives:

1, let the children find the phenomenon that salt can be dissolved into water, and at the same time grasp the relationship between the speed of dissolution and other factors.

2, let children understand that not everything can be dissolved in water.

3, cultivate children's observation, promote children's curiosity, let children have a strong interest in science.

Course tools:

1, prepare enough small cups.

2, prepare enough small plates.

3, prepare enough chopsticks.

4, prepare a bag of salt, a bag of fine sand and a large cup of warm water.

Procedure:

The story is about: the pony to help his mother to buy salt, to cross a river. When he came back, the pony still tripped over the water happily. But when he got to the shore he realized that the salt in the bag was gone. This frightened the pony. He rushed home and told his mother that a demon had snatched his salt from the river. Mom laughed when she heard this. So do the children know why the salt is gone?

2, after getting the children's attention, the teacher began to give the children a demonstration of salt dissolved in water.

Experiment process:

2, the teacher mainly wants the children to observe the state, color, and amount of salt poured into the water.

3, the teacher then change the small cup, the same way to pour the fine sand, let the children observe again, and let the children say the difference between the two experiments.

4, the teacher put the children in groups of two by two, and then let them operate on their own, and carefully observe the process of dissolving salt.

5, the teacher changed the water to cool water and let the children observe once more, so that they could understand that the temperature of the water could affect the speed of dissolving salt.

Course Summary:

This course is very hands-on and requires a lot of observation, so it's perfect for a parent-child game. Parents and friends can play this game with their kids at home if they find it fun. And, of course, you can totally let your imagination run wild and replace or change the whole experiment.
