Lesson 2

Before starting, remember the last lesson:

– What are the objectives of the lesson?
– What have we done?

Step 9. Cut out all the drawn pictures.

Step 10. On the side, on which the blue color is pasted, draw a circle, as in the picture.

Step 11. Cut out the circle.

Step 12. Glue the Sun to the place of the circle.

Step 13. Next, glue the clouds onto blue paper.

Step 14. Place the Moon exactly opposite the Sun and glue the stars onto black paper.

Step 15. From the center of the moon and the sun, we make a groove with a skewer.

Step 16. We shorten the length of the skewer so that it does not exceed the height of the Moon and the Sun, and glue the skewer to the previously cut circle.

Step 17. Skip the skewer from the bottom of the groove.

Step 18. So that the circle does not interfere with the box, cut out and glue four legs from cardboard in four corners

Step 19. Glue the shape of the Earth from plasticine to the head of the skewer (the simplest earth model of plasticine has been created here, you can make changes as you wish).

Step 20. The model is ready (the phone was used for lighting).

Done, rotate the earth using the circle below and you will see how the sun shines on one side of the earth, and the other side remains in darkness. Thus, when the Earth rotates around its axis, day follows night. Each group is free to make changes as they see fit, and each group will defend its models when the model is complete. They not only developed a model of the Earth but also learned about the change of day and night on Earth. That is, the Earth rotates on its own. And they can explain when night and day come.

Conclusion

With the help of the model of the Earth and the sun, we saw how the Earth rotates around its axis and there is a change of day and night.

The change of day and night is the rotation of the Earth around its axis (day).

The essence of STEAM

Science: Students will analyze the relationship between the sun and the earth to determine the cycle of day and night.
Engineering: will create a model of the sun and the Earth.
Mathematics: Students will visually understand the change of day and night with the help of the designed 3D model of the Earth and the sun, which means they will gain an understanding of the day.

Evaluation

PBL grading criterion:
Project-based learning is a learning method in which students acquire knowledge and skills by working on a single project to explore and find an answer to a genuine, interesting, and complex question, problem, or challenge.
