The steps of making clocks and watches by hand in primary schools are as follows:

1, production plan

Pencils and erasers are used to draw and modify dials. Scissors are used to cut paper boards and pointers. Glue or double-sided tape is used to fix the dial and pointer on the base. Rulers are used for measuring and marking to ensure the accuracy of the dial.

Step 2 lay the foundation

Choose a suitable paper cup or plastic cup as the base of the clock. If you need to increase stability, you can apply some glue to the bottom of the paper cup and then stick it on a piece of cardboard or cardboard. Make sure that the paper cups and cardboard are glued firmly and wait for the glue to dry completely.

Step 3 make a phone call

Find a clean piece of cardboard or cardboard and draw a circle with a pencil and ruler. This circle will be used as the dial of the clock. Decorate the dial with colored pens and erasers, and you can draw numbers, scales and hands. If you want to make the dial more stereoscopic, you can apply some glue to the edge of the dial and then stick it on a piece of cardboard or wood to increase the thickness.

Step 4 make a pointer

Find two slender sticks, such as wooden sticks or plastic sticks, as the hour hand and minute hand. Trim the ends of the rod with scissors to the appropriate length and shape for insertion into the small hole on the dial. Stick a small disc or bead on one end of the hour hand and minute hand as a mark.

5, fixed dial and hands

Determine the position of the dial on the base, and then stick the dial on the base with glue or double-sided tape. Insert the hour hand and minute hand into the small hole on the dial and adjust the position so that it can display the time correctly. If you need to increase stability, you can apply some glue to the edge of the dial and stick it on the base.

6. Completion of work

Now, your handmade clock is finished! Put it on your desk or other suitable place to remind yourself to cherish time at any time. If your clock can really run, you can use it as an interesting toy and share your creativity with your friends.

This manual activity can not only help you understand the basic structure and working principle of clocks and watches, but also exercise your hands-on ability and creativity. At the same time, you can also give the made clocks and watches as decorations or gifts to friends and relatives to share your achievements and happiness with them.
