Make a Lego Sundial

Kids are usually impressed by the idea that we can tell time using the sun, and making a sundial is a great summer activity that doesn’t have to involve being outside for too long (though it helps if you can go out and check it every hour for a few hours to see the difference as time goes on).

There are some really simple ways to make sundials, such as with a paper plate and a straw (Ontario Science Centre), using a printable clock face (Paging Supermom) or using a cardboard tube (Learn Play Imagine). I like that this one adds the engineering aspect of building the sundial out of Legos.

If you have multiple kids each one can make their own sundial and compare the lengths of the shadows they make at different times of day. They could also place them in different spots where there is more or less sun to illustrate that your sundial needs to be in the sun for you to be able to read it.

You can get all the details on how to build and mark the time on your Lego sundial from MomBrite. And if you want to turn it into a full-on science lesson, you can explain why a sundial works with a little help from Britannica Kids:

The surface of a sundial has markings for each hour of daylight. As the Sun moves across the sky, another part of the sundial casts a shadow on these markings. The position of the shadow shows what time it is.

The post also notes that ancient Egyptians, Greeks and Muslims all used sundials to tell time. And a fun fact for the word nerds: the part of the sun dials that sticks up is called a gnomon. I didn’t know that!

Growing Up Ladybug and How to Become a Butterfly are both by Stepanka Sekaninova and illustrated by Linh Dao, and they came out at the same time and are on similar themes, so let’s look at them together.

Growing Up Ladybug is narrated by Mariella, a seven-spot ladybug. She talks about the parts of a ladybug, where they live, different kinds of ladybugs, why humans love them, their defenses against predators and the life cycle of a ladybug.

The drawings are cute if not always scientifically accurate, it’s not in such a way that’s likely to confuse kids (who probably already know that ladybug mamas don’t push their larval babies around in strollers, for instance.

It’s a good general description of the life cycle of a lady bug and why we like having them around.

About the book: 32 pages, hardcover. Published 2026 by Albatross Media. Suggested retail price $16.95.

Similarly, How to Become a Butterfly covers the life cycle of a butterfly, starting with caterpillars eating burning nettle leaves. (Here Amanda is the narrator.) The book talks about a few of the more than 18,000 daytime butterflies in the world as well as other creatures that live in the meadow (there’s that ladybug again, along with crickets, bees and other bugs).

It also covers some of the enemies of caterpillars like wasps and spiders, and the defenses that caterpillars use to try to prevent being eaten. It illustrates how caterpillars grow and change as they molt and prepare to pupate, and what a caterpillar looks like before and while it is forming its chrysalis. And while the book uses the word metamorphasis it doesn’t really talk about what happens between the caterpillar forming a chrysalis and the butterfly hatching.

This butterfly is a peacock butterfly, and once it hatches the book covers the parts of a butterfly and the life cycle. It also talks about nocturnal moths (though it says nocturnal butterflies are “usually called moths” when moths are actually a different species) and what butterflies do at night.

I’m maybe a little hard on this book because my daughter is a butterfly expert from way back, but it is still cute and good for the very basic basics of the butterfly life cycle.

Both books would be fun additions to your bookshelf for younger kids starting to learn about different animals or who have an interest in insects.
