Integrated rowing teaching plan for middle class

Children especially like playing with water. When you put a broken boat into the water, there are often boats that get wet quickly and can't float on the water. In order to let the children really understand why some boats can float on the water for a long time, while others sink into the water quickly, I launched this activity. Help children understand the scientific phenomenon that ships sink at different speeds because of different paper suction speeds, and inspire children to better solve problems in life by using existing scientific experience and knowledge.

Activity objectives:

1, understand the different sinking speeds of paper boats with different textures in the water.

2. Learn to describe your findings in words.

3. Have the consciousness and ability of division of labor and cooperation.

Activity preparation:

1. Material preparation: rice paper, newspaper, boats folded with paper, one basin for each group, one tray for each group, one pen for each child, collective record sheet and group record sheet.

2, experience preparation: know several common papers in life, know that paper can absorb water.

Focus of activities:

Can carefully observe the subtle changes of paper when absorbing water, and can describe its findings in words.

Activity difficulty:

Observe and record the cooperation between children.

Activity flow:

1, the beginning part: stimulate children's interest and arouse their thinking.

(1) The problem situation of "three boats absorbing water" caused children to guess the phenomenon of "paper absorbing water at different speeds".
