Letting kids learn more about science at an early age is easier than you think. It is happening all around us, and you can use daily things to arouse (激发) your children's interest. Most parents believe it is difficult to help their children with science. But you don't need a high scientific degree to teach your children science. All you need is that you're willing to try, to see the world, and to take the time to encourage their natural curiosity. When they strongly want to know about something, they get the ticket to the unknown world.
You can help by having an active attitude (态度) towards science yourself. Then start simply by asking your children questions about the things you see every day. Next listen to their answers without judging (评判) them, which will improve their confidence (自信), and help you decide just what your children know or do not know.
Different kids have different interest, so they need different kinds of science projects. Collecting rocks may interest your young daughter, but your older son may need something more to deal with it. Knowing your children is the best way to find enjoyable learning activities. Here are some more pieces of advice: Choose activities that are the right level of difficulty. If you are not sure, pick something easier. Read the suggested ages on any projects, books, and then make sure that the activity is proper for your children. Let your children choose the project or activity themselves. It's easy enough to ask rather than force them. Suggest choosing 2 or 3 things your children can do. When a child picks something he or she is interested in, he or she will enjoy it and learn more from it.
