Xiaobian has prepared some fun science games for everyone in advance, so hurry up and take the children to play in the science activities!

01

Naughty little confetti

Applicable age：Small class

Game goal：

1. Interest in scientific phenomena in life stimulates curiosity and exploration.

2. A preliminary understanding of the static electricity phenomenon caused by friction.

3. Understand that science is closely related to life, and exercise hands-on skills.

Material preparation：

Plates, confetti, salt, balloons.

Gameplay：

1. Pour the small confetti into a plate with salt and stir.

2. Rub the balloon against the hair.

3. Place the rubbed balloon close to the plate and observe what is happening.

Scientific principles：

Static electricity is generated after the balloon rubs against the hair, and charged objects have the property of attracting light and small objects, so the rubbed balloon can attract small confetti.

02

Magic water

Applicable age：Small class

Game goal：

1. Cultivate curiosity about things and be willing to explore and experiment boldly.

2. A preliminary understanding of the simple principle of refraction.

3. Improve observation ability and hands-on ability.

Material preparation：

Transparent water cup, clear water, and a piece of white paper with directional arrows.

Gameplay：

1. Place the blank transparent water cup directly in front of the white paper with the arrow on the side.

2. Add water to the transparent cup until it is full.

3. Observe whether the direction of the arrows on the white paper has changed.

Scientific principles：

The cup injected with water is like a convex lens. The incoming light changes direction after refraction. The arrow forms an inverted virtual image in the convex lens, which changes direction.

03

Dancing red beans

Applicable age：Middle class

Game goal：

1. Be interested in scientific phenomena in life and actively participate in exploration activities.

2. Feel the interesting phenomenon of the ups and downs of red beans.

3. Improve observation and hands-on ability.

Material preparation：

Baking soda, white vinegar, water, transparent cup, stirring stick, red beans.

Gameplay：

1. Pour two spoonfuls of baking soda into a transparent cup.

2. Pour in a little water and stir with a stirring stick.

3. Pour a small amount of white vinegar multiple times.

4. Pour in the red beans and observe the state of the red beans.

Scientific principles：

Baking soda and white vinegar react chemically, producing carbon dioxide gas to form air bubbles. The air bubble is attached to the red bean, and the buoyancy it receives is greater than the gravity, so it floats to the liquid level. After that, the air bubbles burst due to contact with the air, and the buoyancy it receives is less than gravity and it sinks to the bottom of the cup. In this cycle, the red beans appear to be “dancing”.

04

Rainbow Bridge

Applicable age：Middle class

Game goal：

1. Feel the fun of science in exploration.

2. Initially feel the capillary phenomenon of paper towels.

3. Exercise hands-on skills.

Material preparation：

White paper towels, colored pens, and two glasses of water.

Gameplay：

1. Use a color pen to paint a variety of colors on both ends of the white paper towel.

2. Place two cups of water side by side, place the tissue holder on top, and place the two ends of the tissue in two cups.

3. Observe how the tissue changes.

Scientific principles：

This is a capillary phenomenon. Water will rise along the capillary tube. The gaps in the paper towel can be regarded as capillaries, so the pigment will go up along the paper towel.

05

Milk Secret Letter

Applicable age：Big class

Game goal：

1. Feel the interest of science and stimulate the desire for exploration and curiosity.

2. A preliminary understanding of the different ignition points of different substances.

3. Exercise hands-on skills.

Material preparation：

White paper, milk, candles, cotton swabs, matches or lighters.

Gameplay：

1. “Write a letter” on white paper with a cotton swab dipped in milk.

2. Put the written “letter” aside and wait for it to dry.

3. Light a candle, place the ”letter" at a distance of 5-10cm from the flame and bake to observe the phenomenon.

Scientific principles：

The protein denaturates at about 60 degrees Celsius, coagulates, and appears, and the ignition point of the paper reaches more than 130 degrees, so the above phenomenon occurs.

06

Paper cup projector

Applicable age：Big class

Game goal：

1. Be interested in science and feel the fun of exploration.

2. A preliminary understanding of the conditions under which shadows arise, and an understanding of the relationship between light and shadow.

3. Cultivate observation and hands-on skills.

Material preparation：

Scissors, paper cups, color pens, tape, flashlights.

Gameplay：

1. Use scissors to cut off the bottom of the paper cup.

2. Seal the bottom of the paper cup with an appropriate amount of scotch tape.

3. Use a watercolor pen to draw your favorite pattern on the tape.

4. Find a room without light, turn on the flashlight and point it at the mouth of the cup, and the pattern can be projected on the wall.

Scientific principles：

When the flashlight is facing the mouth of the paper cup, the light emitted by the flashlight can only be emitted from the mouth of the paper cup. We will see a circular spot on the wall. The farther away, the larger the spot. If you draw a pattern on the scotch tape, the pattern will appear along with the spot of light, so that you can see the pattern on the wall.
