To continue our STEAM children’s book series, let’s explore the childhood adventures of nine scientists in What’s in Your Pocket?: Collecting Nature’s Treasures by Heather L. Montgomery and illustrated by Maribel Lechuga.

When children collect and sort items they find in nature, they are learning important STEAM skills. In this book you will meet a boy who collected rocks and beetles, another who collected seeds and seed pods, and a girl who slept with earthworms under her pillow. Keep reading to find out which famous naturalists and scientists these curious children grew up to be.

They’ve created collections
They’ve made discoveries.
They’ve changed the world of science.

Maribel Lechuga’s vibrant illustrations perfectly capture each child’s wonder and surprise at the new things they stumble on.

The back matter gives a more complete biography of each of the people featured in the text, plus a charming note from the illustrator about how artists also appreciate and observe nature. In her author’s note, Heather Montgomery explains the need for collecting responsibly and gives some rules for respecting nature, respecting your family and community, and for protecting yourself when you gather from nature.

What’s in Your Pocket? is a delightful celebration of the collections made by youngsters who became famous scientists and naturalists. It is sure to inspire the next generation to make their own discoveries. Check out a copy today.

Activity 1. Make a leaf collection

Fall is a great time to make a leaf collection.  Use fallen leaves as an opportunity to study leaf form and function.


  1. Gather the leaves.
  2. Preserve the leaves.
  3. Display your collection.

Be sure to gather the leaves where you have permission to do so. A cloth bag can help hold your leaves while you are collecting.

There are many, many ways to preserve leaves. Personally, I press mine in between the pages of a few large books I keep for that purpose. This is something I learned from my grandmother. I still occasionally find a pressed leaf she tucked away in one of her books, a hidden treasure.

You may:

Be sure to include when and where you collected your leaves and any information you have about the identity of the plant. Keeping detailed records makes your collection more valuable as a scientific resource.

Use your preserved leaves to make and display a leaf collection. For example, see these third grade examples.

Activity 2. Make a Seed Collection

In places with distinct seasons, plants often release their seeds in fall. To start, look for big seeds like acorns, maple keys, horse chestnuts, or walnuts. Here in Arizona we have mesquite pods.

If you can’t get outdoors, search for seeds inside common fruit like apples or pumpkins. Just be aware that learning how to dry and preserve seeds from fruit can be a bit of an art. There are books on saving seeds and many communities have seed libraries with information to help you get started.

A first collection can be stored in an egg carton (also useful for small rock collections). Bigger collections can be held in clean, dry spice jars or in labeled paper envelopes. As with the leaf collection, include when and where you collected your seeds and any information you have about the identity of the plant.





The diversity of seeds is amazing. To give you some idea of the different kinds, here at Growing with Science blog I posted a different seed photograph for 257 weeks in a row. First I posted the photographs — without identifying them — as mystery seeds. The following week I posted the identity with information about the plant (Seed of the Week). Many are listed by plant common name in the Seed of the Week archive page.

Activity 3. Make a list of things to collect

Brainstorm a list of other things that people collect.

  • Rocks
  • Seashells
  • Insects (particularly butterflies)
  • Pine cones
  • Bits of bark
  • Driftwood
  • Bones
  • Fossils
  • etc.

Discuss how these collections might be used, such as learning how to identify the items collected or figuring out where they can be found (geographical range).

Do you have a collection? What do you collect? How have collections inspired you?
