Finding “Waldo” Seedling

We learn in Nancy Larson® Science 1 that seeds from broad-leaf trees fall to the ground and begin to grow into seedlings. Some seeds are heavy, such as acorns, and fall close to the parent tree. Other seeds, such as maples and elms, are carried by the wind and may land far from the parent tree.

It’s not too surprising that I found this little seedling growing among my flowers.

Wondering how far it traveled, I looked for the adult tree and found this maple tree about two hundred feet down the street. It’s the tree in front of the blue mini-van.

I compared the leaves to see if they were the same.

Then I wondered, “Where are other seedlings from this tree?”

Here’s one I found growing in the grass about twenty feet from the adult tree.

The photo on the right shows the seedling and the parent tree. Do  you see the little seeding in the grass?  It’s at the bottom of the photo.

Were there other young seedlings growing, almost hidden, in the grass? I kept looking very carefully to find more.

Here’s another seedling.

Here’s the adult tree about thirty feet away from the seedling.

Where are tree seedlings in your yard?  Finding them is like a “Where’s Waldo?” picture. Sometimes you need to take extra time, get up close, and look carefully. Then you’ll find them.

How many seedlings can you find?

How far are they from the adult tree?

How do you know which adult tree is the parent?

Could you create a graph that shows how far the seedling is from the adult tree?

Take photos to document your finds.

We’d love to see them and will share with others.

Enjoy finding “Waldo” seedlings!

The Worm Jar – Jolanthe Erb

At the HEAV conference in Richmond, Nancy and I had a great visit with two homeschool moms on our Parent Support Group, Kathryn Bremner and Jolanthe Erb. Along with their experiences using Nancy Larson® Science, Kathryn and Jolanthe shared ideas for homeschool field trips and extra science projects. Nancy and I are both very interested in composting, so I asked Jolanthe to share this project.

The Worm Jar – Jolanthe Erb,

The kids were thrilled with the prospect of bringing a big ol’ handful of worms into the house. The purpose? To see how {and if} worms compost, dig tunnels and mix soils.

Mommy? Perhaps not as thrilled as the kids were at the prospect of there being worms on the loose should a certain 5 year old manage to get hold of the jar. But she persevered…

Want to try this at home? Here’s what you’ll need:

  • a quart size canning jar
  • a lid with holes in it
  • dirt/soil/hay/grass
  • worms
  • dark colored felt or paper

First we layered dirt into our jar ~ rich soil from the garden, some lighter sand, some mulch {layering soil, sand, mulch, soil, sand…}. When we had filled the jar, we had fun digging for worms and added them to the top of the jar. We also added some food {teeny tiny chopped carrots, celery greens, chopped apples, etc…} for the worms to mix into the soil ~ we hoped.

We made sure the soil was slightly damp, put the lid on our jar and wrapped in a piece of dark brown felt so that the worms would have some darkness to work in. We even put the jar inside one of our cabinets so that it was good and dark.

Every few days for the next two weeks we continued to check on our worm jar to see how our little underground friends were doing ~ and if they were doing their jobs.

We filled out a simple science notebooking sheet with our predictions and observations to track our worm’s activities.

Some fun facts we learned about worms:

~ The only places where earthworms don’t live are in the desert and where the ground is frozen.

~ Earthworm poop is called ‘castings’.

~ Worms have two layers of muscles ~ one that runs lengthwise and one that runs around, helping its body stretch and contract.

~ Worms have a coat of slimy mucus that helps them glide through the dirt.

~ Sunlight can kill a worm because they are sensitive to the UV radiation.

~ Worms are sensitive to temperature and touch.

~ Worms do not have ears, rather they ‘hear’ by sensing vibrations.

Here is a peek at our jar after 3 days. Can you see one of our worm friends near the top of the jar? See how our soil is already mixing? We had to add a little water/moisture to the jar to help out our worm friends.

After two weeks there were no obvious layers anymore. Our worms had been hard at work mixing and composting our soil. After we observed them, we took them back to our garden and let them do their work around our vegetables. 🙂

Changing Leaves for Emily

Changing Leaves

A very sweet note came the other day from Emily, who’s six. Here’s her question:

Do leaves change from green to orange or yellow all at once?

Sometimes the best way to learn is to just stop and look. Since Emily isn’t here to look with me, here’s what I want her to see.

This tree has a green and orange look. But when we stand closer, we see this.


This tree seems to have been dipped in pink. Standing close to the trunk, we see these leaves.
Then we see some very colorful branches among the green. Moving out a little, we see both the green and pink.


From thirty feet away, this tree is green and yellow. But up close, it’s more green and pink.
Here’s the same tree one week later. See how the colors have changed.


This tree looks green with some yellow. Up close we see each branch has leaves with many wonderful colors.


How would you answer Emily’s question?

When you draw a tree in autumn, what colors would you use?

You can print the drawings of a tree and leaf below. Color the leaves to show a tree in autumn.
