Studies have shown that the kindergarten and primary school stages are the key periods for the implementation of science enlightenment education!
During this period, the child's brain activity is twice that of adults, the thinking response is the most agile, and the child's scientific thinking ability and creative ability can be cultivated in time and well during this period, and will be highly developed when entering the school stage or adulthood; on the contrary, it is not easy to develop.
Astronomer Carl Sagan once said, "Every child is a scientist because they, like scientists, are full of curiosity and awe for the wonders of nature." ”
When children are observing ants and snails, when children are playing with water and sand, that concentration is like a little scientist.
And we as parents, if we can keep our children curious and exploratory, so that they can maintain awe of the world, then their growth will be happier, their world will be more colorful, and their independent thinking ability will be more stimulated.
Today, I will share with you 4 scientific enlightenment experiments that can be done at home, inspire children's scientific thinking with examples from life, and cultivate children's ability to think independently!
Experiment 1: Unbreakable water bladder
Preparation materials: Seal plastic bag, pencil, appropriate amount of water
Experimental steps:
❶ Pour water into the sealed bag and seal the sealed bag.
❷ Thread the pencil through the water bladder.
❸ Then insert the second and third pencils.
Experimental principle:
Whether the water bag is pierced is actually determined by the material of the sealed plastic bag. Plastic bags made of polymers have high softness and strong stretch. The moment they are punctured, they quickly rebound to wrap around the pencil, leaving no gaps, so that although the water bag is punctured, it can still keep dripping water.
Experiment 2: Heat conduction
Preparation materials: transparent small cup, color, transparent container, appropriate amount of water
❶ Add the pigment to a small transparent cup and pour hot water to mix well.
❷ In a transparent container (e.g. fish tank) into three-quarters of the water.
❸ Put the small cup with the colored water into the transparent container, and you can see the water in the small cup spreading into the container.
Experimental principle: heat conduction.
Color flower experiment
Experimental materials: white carnations, food coloring, water, cups
Experimental procedure: Insert flowers into colored water and ask children to guess what will happen? After 1 day, ask your child to observe what happened? And think about why?
Egg swallowing phenomenon
Experimental materials: a hard-boiled egg peeled, a bottle with a bottle mouth slightly smaller than the egg, and an alcohol cotton ball
Experimental procedure: Light the alcohol cotton ball and throw it into the bottle, quickly place the egg on the bottle mouth, ask the child to observe, and predict what will happen? The egg slowly slides into the bottle due to the action of air pressure. Ask your child to think about why?
