How parents can help their children in learning science

Contributed by:

Young children ask their parents hundreds of questions like these. In search of answers, we use science to both enlighten and delight. Being “scientific” involves being curious, observing, asking how things happen, and learning how to find the answers. Curiosity is natural to children, but they need help understanding how to make sense of what they see and to relate their observations to their existing ideas and understandings. This is why parental involvement is so important in children’s science education. When we encourage children to ask questions, make predictions, offer explanations and, explore in a safe environment, we lend them the kind of support that they need to become successful science students and scientific thinkers.

4. Introduction
As a parent, you are preparing your child for a world vastly different from
the one in which you grew up. Our increasingly technological society will
need citizens who have received far more advanced instruction in science
and technology than most of us received when we were in school. Even
children who don’t want to become physicists, chemists, engineers or
computer technicians will need some knowledge of science and technology
just to conduct their everyday lives. Every citizen needs to be scientifically
literate in order to make informed decisions about health, safety and
citizenship. Our children need our help and guidance to prepare for the
world that awaits them.
Scientific knowledge is cumulative: To learn new things, you must build
on what you already know. So, it’s important that your child start learning
early—and at home. A good way for you to begin the learning process is
by sharing your own interest in science. How you view and talk about
science can influence your child’s attitudes toward science—and how she1

excel at the highest levels in math and science. you can’t make your child like science, you can encourage her to do so,
and you can help her to appreciate its value both in her everyday life and
in preparing for her future.
—President George W. Bush
In everyday interactions with your child, you can do many things—and do
them without lecturing or applying pressure—to help her learn science.
Here are a few ideas:
★ See how long it takes for a dandelion or a rose to burst into full bloom.
★ Watch the moon as it appears to change shape over the course of a
month and record the changes.
★ Look for constellations in the night sky.
★ Bake a cake.
1. Please note: In this booklet, we refer to a child as “she” in some places and “he” in others. We do this to make the booklet easier to read.
Please understand, however, that every point that we make is the same for boys and girls.

Glass? Talk about the reasons for using these materials.
Learning to observe carefully is an important step leading to scientific
explanations. Experiencing the world with your child and exchanging
information with him about what you see are important, too.
Finally, encourage your child to ask questions. If you can’t answer all of her
questions, that’s all right— no one has all the answers, not even scientists.
For example, point out that there’s no known cure for a cold, but that we
do know how diseases are passed from person to person—through germs.
Some of the best answers you can give are, “What do you think?” and “Let’s
find out together.” Together, you and your child can propose possible
answers, test them out and check them by using reference books, the
Internet, or by asking someone who is likely to know the correct answers.

6. The Basics
What Is Science? Even older children can come up with unique “scientific” explanations, as
in the following examples provided by middle-school students:
Science is not just a collection of facts. Of course, facts are an important

★ Classifying or organizing information;
★ Predicting what will happen; “Gravity is stronger on the earth than on the moon because here on earth we have
a bigger mess.”
★ Testing predictions under controlled
conditions to see if they are correct; and
“A blizzard is when it snows sideways.”
★ Drawing conclusions.
Asking Questions
Science involves trial and error—trying, failing As mentioned earlier, it’s important to encourage your child to ask

Finding the Right Activity for Your Child
Different children have different interests and will respond differently to
science activities. A sand and rock collection that was a big hit with an
8-year-old daughter may not be a big hit with a 6-year-old son.

Children can learn more about surface tension and about change just by
blowing bubbles! Bubbles are bits of air or gas trapped inside a liquid ball. The
surface of a bubble is very thin. Bubbles are particularly fragile
when a dry object touches them. That’s because soap film
tends to stick to the object, which puts a strain on the bubble.
