1, clouds and raindrops

Steps: Fill one cup with blue water to simulate "rain" and the other cup with cotton balls to simulate "clouds". Invite children to pick up cotton balls with clips and soak them in blue rain water to simulate cloud water absorption. Squeeze the rain from the soaked cotton ball with your small hands. This process of simulating "rain" can exercise children's fine movements and enjoy playing with water.

2. Sink &; Floating upward

Step: Collect some objects, some will float and some will sink. Let your child predict what will sink and what will float. Put the object in the water to see if the child's prediction is accurate.

3. Plant growth

Steps: Teach children to take some peas, put them on kitchen paper towels, then gently wrap them, and then spray peas and paper with a spray bottle. Remind children to spray water with paper every day to keep the seeds moist. Observe the germination and growth of seeds every day. Tip: You can use a magnifying glass. Germinated seeds can teach children to transplant into small flowerpots filled with potted soil to remind them to keep the soil moist.

4. Leaves absorb water

Step: Drop two colors of food coloring into a cup filled with water. Immerse two Chinese cabbage leaves in water dyed with different colors and let them stand for one night, and you can see that the Chinese cabbage leaves are obviously dyed with pigment.

6. magnetism &; Nonmagnetic

Step: Find out some small objects and make sure that some objects contain iron-containing substances that can be attracted by magnets. Let children use magnets to check which objects can and cannot be sucked up. Divide magnetic objects into one category and nonmagnetic objects into one category.

7. Water and oil

Steps: Let children use magnets to check which objects can be sucked up and which ones can't. Divide magnetic objects into one category and nonmagnetic objects into one category. Let the children observe whether the oil can be dyed, and then stir it as fully as possible to see if the oil can be dyed by hard work. No matter how hard children try, oil can't be dyed, because water and oil can't be mixed, and because the density of oil is lower than water, it will float on it.

8. Dancing raisins

Steps: Let the children observe whether the oil can be dyed, and then stir it as fully as possible to see if the oil can be dyed. You can put raisins in a cup of boiling water at the same time and see if there will be the same reaction.

9. Volcanic eruption

Step: Pour the hydrogen peroxide into the plastic bottle, drip the food pigment and add a small amount of detergent. 1 tbsp yeast is dissolved in warm water and poured into plastic bottles. Next, watch the super interesting eruption effect with the children! Foam will come out of the bottle. Please observe carefully.

10, plant transpiration

Steps: Put a transparent plastic bag on the plant and fix it with adhesive tape. Wait 20-30 minutes (actual operation, depending on regional conditions, may be longer). Next, observe with your child whether there is a layer of water droplets on the plastic bag wall!
