Preschool science activities
How to nurture your child's interest in the natural world

Can we design better preschool science activities? Activities that
stimulate curiosity, teach science concepts, and avoid overwhelming or
boring children with lessons that are developmentally inappropriate?
In the article below, I review the advice of educational and
cognitive psychologists about preschool science education. But if you
are looking for specific activities, you can also check out these links:
Floating and Boating
is a set of science activities that encourage kids to play in the water,
explore the concept of buoyancy, and make some cool contraptions.
is a set of activities that encourages kids to investigate the properties of dirt and mud.
offers young children opportunities to exercise their spatial and scientific reasoning skills.
Experiments with ice cubes
introduce kids to aspects of the scientific method, as does this
allow kids the opportunity to make and test predictions.
Activities for encouraging the use of science tools
may motivate kids to take measurements and develop fine motor coordination.
Preschool science activities:
How researchers suggest we teach science--and the scientific method--to young children
When done well, preschool science is exciting and intellectually meaningful. The right preschool science activities can
• nurture your child’s natural sense of adventure and curiosity
• help your child develop his own understanding of the natural world
• encourage your child to be a persistent problem solver, and
• introduce your child to basic elements of scientific reasoning (seeking evidence; testing predictions)
So what’s the right way to teach science? Here are some
recommendations based on the work of Rochel Gelman and other
Don't force it and don't lecture
Preschooler brains aren’t prepared to handle tasks that require them
to sit still and focus their attention on your every word. Moreover, recent experimental studies indicate that merely telling a young child "this is how it works..." has the effect of dampening his curiosity and initiative.
Preschoolers given opportunities to investigate a new device actually showed less inquisitiveness and critical thinking after an adult explained how to use the device (Bonawitz et al 2011; Buchsbaum et al 2011).
For some ideas on how to cope with this problem, see my model for encouraging independent experimentation in preschoolers.
Teach through hands-on experiences
Preschoolers learn best by doing, so choose preschool science
activities that emphasize hands-on experiences and require minimal
explanation from you.
Build on what your child already knows
Learning about something completely unfamiliar is relatively hard.
It’s much easier to learn more about something you are already familiar
Although they are young, preschoolers have nonetheless begun building concepts in a variety of core subject areas, or domains.
Cognitive psychologist Rochel Gelman argues that you should
choose preschool science activities that feed into these pre-existing
Some of these learning paths include:
• cause and effect sequences pertaining to every day objects (e.g., popsicles melt in the sun-—Gelman et al 1980)
• structure and function (like the relationship between the shape of an animal’s teeth and its diet)
• variation and classification--the idea that different objects
or organisms have distinct properties (e.g., “mammals have fur; birds
• how nonliving physical things change (e.g., a toy becomes a broken toy—-Gelman et al 1980; Das Gupta and Bryant 1989)
• how living things grow and change (Rosengren 1991)
• how the insides of a living thing differs from the insides of an inanimate object (Gelman 1990)
• how living things move
• how animals and people think (i.e., they have goals and desires)
These learning paths can be linked to a wide range of preschool science activities (see next section).
Choose preschool science activities that are conceptually connected to each other
While it might be tempting to jump from topic to topic, kids are more
likely to learn when they are given many opportunities to think about
the same concept (Gelman and Lucariello 2002; Winnett et al 1996).
To make science lessons more meaningful, Rochel Gelman and her
colleagues recommend that you choose one or two central concepts—like
“insides and outsides” or “biological change and life cycles”—and stick
with these core concepts for months at a time (Gelman and Brenneman
At first blush, this might sound rather limiting. But the central
concepts are broad and yield themselves to a wide range of preschool
science activities. For instance, if you choose to focus on “biological
change and life cycles” you might spend time exploring
• Seeds and plants (e.g., counting the seeds inside an apple;
planting the seeds; observing how plants grow under different
• The life cycle of various animals (e.g., learning about frogs, puppies, butterflies, humans, etc.)
• Measuring growth in plants and animals
• Health and illness
Encourage your child’s special interests
The “learning paths” mentioned above are based on what most (if not
all) kids know about. In fact, they relate to core domains of knowledge
that may be “universally learnable with relative ease” (Gelman and
But these are not the only learning paths of importance. Your
child might have a special interest in rocks, or automobiles, or cats,
or animal behavior. Pay attention to these interests and find preschool
activities that build on them.
Stick to subject matter that is age-appropriate
Beware of tendency to adapt preschool science activities from lessons
designed for older kids. Encouraging your preschooler to mix paint
colors or explore shadows is a fine idea. But it makes little sense to
tackle the physics of light waves.
Don’t “dumb down” the vocabulary
When we learn new concepts, our brains have to “file” these concepts
away. Our brains do this, in part, by connecting the concepts with
vocabulary. In this way, the concepts and the terminology are intimately
So don’t try to “dumb down” the language when you introduce your
child to new information. If you are teaching kids about respiration,
call it respiration (Gelman and Brenneman 2004).
Make science tools a part of everyday life
Some preschool science activities involve the use of science
tools--like magnifying glasses, rulers, and balance scales. Once your
child becomes familiar with using such tools, keep them available
throughout the day, not just during preschool activities (Gelman and
Make preschool science activities an opportunity to learn the scientific method
Scientists develop hypotheses to explain the world. Then they ask
themselves what ought to happen IF their hypotheses are correct. Testing
these predictions--and analyzing the results--is the essence of the
Some science activities permit kids to explore on their
own—-without making them conscious of the scientific method. These
activities are valuable, but kids can also enjoy more structured
activities that explicitly teach the scientific method. Rochel Gelman
and her colleagues recommend introducing kids to the terms
