How to make a clock in a small scientific experiment

How to make clocks in scientific experiments;

1. Found two paper trays and an analog clock. Paper trays are used for clocks, and analog clocks are used for reference.

2. Fold the paper tray in half. Let the child hold his paper tray, fold it in half, then rotate the paper tray and fold it in half again. A cross crease should be formed in the middle of the paper tray, and this crease should be used as a reference point.

3. Put stickers and numbers on the clock, let the children put a sticker on the top of the clock at 12, and then let them write down the number 12 with a marker under the sticker according to the pointer clock, and also write down 3, 6 and 9.

4. Fill in the numbers on the clock. After the children put stickers on the clock and write down the numbers 12, 3, 6, 9, let them write down the remaining hours and tell them to write according to the analog clock.

5. Split the clock board. Let the children draw a straight line from the center to the number, and let them color each part with crayons of different colors. Try to paint a little red first, and then paint several colors of the rainbow one by one.

6. Make clock hands. Draw two clock hands on the poster board. The long hand represents the minute hand and the short hand represents the hour hand. Let the children cut the clock hands with scissors.

7. Install the pointer. Put the hour hand on the minute hand, use a pin to pass through the end of the clock hand, then use it to pass through the center of the clock plate, turn the clock, twist the end of the pin and fix the pointer, and the manual clock is completed.
