Hatched

Remember our Monarch caterpillars?

Well one hatched!



Moe was jumping up and down yelling for me to come look when she came home today (I had noticed it when I walked in the door). I can't wait for the older girls to get home and see it.

Before I picked Moe up from preschool, I noticed it looked close to hatching but the website I looked it up on said it still had about 24 hours so I left it at home. I was going to bring it and give it to Einey to bring in with her from recess. But I didn't. That's the last time I believe something I read on the web!

Homegrown Scientists

In Einey's school, there is such a focus on reading, writing and math, that the teacher is only allowed 20 minutes a week for science and history. 20 minutes! So when I saw the topic for this week's parent blogger blast, I just had to share some of the ways we've brought science back to our kids.

Science is all around us. It's prevalent throughout nature and the natural world. Last summer, when the girls found this cicada emerging from it's pupal state, we watched. And took pictures. And discussed. And then we looked it up on the computer. We frequently take hikes in the woods on our letterboxing quests. On our hikes, we discuss weather (and how it changes - we've been caught out in the woods in rain bursts), we identify plants and animals. We look under rocks and logs. We catch frogs and salamanders. In short, we take the time to really look at our surroundings and discuss the hows, the whys, the whats. How things change and why they change. How every little creature affects other creatures.

In addition, we do experiments with our gardens. When planting seeds inside for the spring, we measure and chart their progress. When building our sunflower house, we measured the sunflowers, first from seedlings with a ruler, then outside with the kids. We discussed how the plants were growing and then when they finished their growth, how they provided nectar for the bees and lastly seeds for the birds. In the spring, I have a suspicion we'll discuss the life cycle circle they made, as I am sure we'll have new sunflowers sprouting in the garden.

We've done sink or float test with them gathering objects and making predictions. Currently, we have a crystal growing on the counter in the kitchen.* We've frozen water and watched it melt. We mix water and other liquids to see what's heavier. We've looked at the viscosity of different liquids. We take tours where they are offered - power plants, nature sanctuaries, science center. We've discussed actions and reactions (like the time Husband threw a wooden block at the window - of course it broke). We spend evenings out on the deck looking at the stars. We pull out the telescope and search the sky's. We watch meteor showers and eclipses (Einey was very impressed by the lunar eclipse the other night). We visit science centers on rainy days. We discussed changes that come with the season (and living in New England, we have four very unique seasons each with it's own specific characteristics). Just the other day, we discussed how and why this river changed from autumn to winter. I wasn't at all surprised last week, when Einey's teacher told me they started discussing the water cycle and Einey knew all about it and was able to name the cycles.

Science is all around us. It's all a matter of taking time to look at the little things and really discuss the how and why's. As long as they keep asking questions, we will answer. We'll keep searching under logs, splashing in rivers, filling jars with liquids. We'll keep measuring and labeling and recording. For my girls, science is fun. And learning is a bonus. We will bring science back through hands on fun.


This post was created for the Parent Blogger Network's Friday Blog Blast and the Zula Patrol's Zula Intergalactic Inquirer. They want to know, how will you bring science back for your kids, and why do you think it’s important?

*Because it's a quick and easy science experiment, here's what you do: You need a jar, water, salt, a string and a pencil. Tie the string around the pencil. Fill the jar with water and then salt until the salt is dissolved. Put the pencil over the jar with the string hanging in the jar. As the water dissolves, the salt will crystallize to the string. You can see the results start within hours! Just add a little more water and salt as it dissolves for a bigger crystal.

Backyard Science

Yesterday morning, the girls were quietly playing in the yard and raiding the raspberry bushes when Meenie comes running into the house quickly followed by Einey.

Meenie: Mom, there is a yucky bug outside. It's nasty.
Einey: It's not a bug, it's a chrysalis or a cocoon.
Meenie: It's a bug. It has eyes.
Me: Okay slow down, what?
Meenie and Einey: repeats their spiel again.
Me: Ok, show me. We'll figure out what it is.

I go out side to look and find that both girls are partially correct. They found this:

A cicada shedding it's nymph skin. Only they saw it as it was just poking it's head out of the outer shell.


Looking through the magnifying glass for a closer look.


The shell it discarded.

This is the second year we have found one of these guys emerging from their old skin. They are very neat to watch as they climb out of the old skin and sit for about an hour, drying their wings in the sun. Then they climb the fence/tree/stairs and fly away. Last year we found alot of empty shells around the fence. It was a great science lesson for the girls as they sat there until it flew away and watched it. With the magnifying glass they saw details on it that they couldn't see without it.

Then it was back to raiding the raspberries!
