Science Experiments for One Child at the Kitchen Table

Most science activity ideas assume a group. When it’s just you and one child, things are different, and in many ways easier. You can follow their interests, move at their speed and talk about what you see as it happens.

Here’s how to make the most of it at the kitchen table.

The advantages of one-to-one

You can follow their questions. If they notice something unexpected, you can chase it straight away.
Everything is hands-on. There’s no waiting for a turn, so the child does the pouring, measuring and observing.
Conversation is easy. With one child you can ask a question, wait for the answer and ask another.
You can adjust on the spot. If it’s too easy, add a twist. If it’s too hard, simplify.
Prep is smaller. One set of materials is all you need.

The one thing to watch is that it’s easy to take over. With only two of you, it’s tempting to just do it. Hold back and let the child try, even when they’re slower.

Set up the table

Clear a space about the size of a tray, and put a tray, baking sheet or old towel under the activity.
Put out only what you need. Extra items are distracting.
Keep a bowl of water and a cloth to the side for spills.
Give your child a notebook and pencil so they can draw and record.
Agree on safety rules first: nothing goes in mouths, an adult does anything hot or sharp, and you wash hands afterwards. See our kitchen science safety rules.

Ideas that suit one child and one adult

Each of these uses ordinary things, takes about 20 minutes and works well as a pair:

Sink or float. Collect 8 to 10 small objects. Guess, then test in a bowl of water. Sort into two piles and look for a pattern.
Which paper towel soaks up the most? Compare brands or layers using a measuring jug and a fixed amount of water.
Ice cube race. Put ice cubes in different places, such as a window, a bowl of water or wrapped in a cloth, and time them with a clock.
Shadow drawing. Put a toy by a window and trace its shadow every 30 minutes through a morning.
Mix and dissolve. Stir a spoon of sugar, salt and flour into separate cups of water. What disappears and what doesn’t? Remember: no tasting.
Paper plane test. Make two designs, change one thing, and measure how far each flies with a tape measure.

For something with a clear recipe, try Is Oobleck a Solid or a Liquid? or What Makes a Paper Plane Fly Farthest?.

Roles when there are only two of you

Try splitting jobs, even if it feels a bit formal:

The scientist does the test.
The recorder writes or draws what happens.

Then swap halfway. Swapping gives children practice at both careful doing and careful noticing, and it stops you from drifting into doing all of it.

Keep the talking going

Use short questions that can’t be answered with yes or no:

“What do you think will happen?”
“What do you notice?”
“What’s different from last time?”
“How could we make it fair?”

More ideas are in our post on questions to ask during science experiments.

Tidy up together

Make clean-up part of the activity. Pour liquids down the sink, wipe the table, wash cups and put your materials back where they live. Then, while things are fresh, add one line to the notebook: “What did we find out?”

When it’s one child of any age

Younger children (5 to 7) need short sessions of 10 to 15 minutes and lots of handling. Older children (8 to 12) can handle longer, more careful investigations and more writing. Teenagers often enjoy being asked to design their own test. Let them lead.
