Science Week: Day 5

We are nearing the end of Calvert 1st grade, so we decided to knock out the last two chapters in our science book with a dedicated Science Week! So far we have explored position and force and simple machines and magnets. Then we started investigating the different types of energy: first heat and then sound.

It's the last day of Science Week! Just as heat and sound are types of energy, so is light! Light is the form of energy that allows us to see.

Some materials let a lot of light pass through them. Other materials block out light completely. Miss M tried a few materials to see what lets light through and what doesn't.

Plastic wrap, waxed paper, aluminum foil, an empty paper towel tube, and a rubber band.

First she covered one end of the tube with plastic wrap and tried looking through it. She could see light! Then she removed the plastic and covered the end of the tube with waxed paper. She could see some light, but not as much as before.

Lastly, she covered the end of the tube with aluminum foil.

Whoa! No light came through at all! She recorded her findings.

How does light help us see? When light hits an object the light bounces off the object and right into our eyes! We wanted to see what bouncing light looks like, so we took a flashlight and a small mirror into the bathroom (there are no windows in there and it gets very dark, even in the middle of the day!)

Miss M shined the flashlight into the mirror and looked around to see where it went when it bounced off the mirror. We stuck a paper target on the wall and tried to aim the light to hit the target!

Light bounces off the mirror and hits our paper target.

Sometimes when light shines through a material, the light can be changed. Miss M and Little Guy took turns shining the flashlight through colored paddles. When the light shone through them, the color of the light was changed!

The colors were very pretty!

We liked the colored lights so much we decided to make our own stained glass window art. Miss M and I each took a piece of black construction paper, folded it up, and cut shapes from it. When we opened it, we had a frame for our stained glass art.

Then we cut small bits of colored cellophane wrap and taped them across the holes on one side. When we flipped the frame over, we could see the pretty colors in the frame!

By the time we finished it was dark outside. Too dark to hang up our pretty artwork and admire the sun shining through. Oh well, we'll hang them up tomorrow and enjoy the colored lights then!

Thank you for joining us for Science Week! We had so much fun and learned a lot. If you try any of our experiments, we would love to hear about it!

MFW ECC: What's different this time around?

I am so excited to go through Exploring Countries and Cultures again. The last time my kids were so little -- 3rd grade and Kindergarten. And now they are in 5th and 8th grades! They have grown so much over the past five years. As I began to think about our plan for this year, I realized two things: 1) my gifted eldest child remembers just about everything we covered in ECC the first time, and 2) my younger one hasn't had many of the basics that ECC covers. So I was faced with a dilemma -- how do I adjust ECC to suit the very different needs of both children? How do I shift the focus for my 8th grader to aspects of ECC that she hadn't spent time on before (such as types of governments, imports and exports, etc.) while also taking my younger child through the more foundational information that he missed when he was just a kindergartener? ECC is designed to be parent-led, family learning, with a supplement for 7th and 8th grade. But I came to the conclusion that I need to deco...

Pilcrow pajamas

I finally finished a sewing project...it's been a while, huh? Little Guy has outgrown most of his pajamas and bodysuits. He has several onesies, but they're mostly short sleeved which isn't really appropriate for this time of year without a cardigan. Ottobre to the rescue! I had traced off the "Naava coverall" (Ottobre 6/2009, #3) but it was already a size too small. I "remedied" that by simply cutting it out a little larger all around and keeping my original seam allowance...a bit sloppy perhaps, but time-saving! I actually cut out two at the same time from the same material. I was going for practicality (something for the kid to wear!) rather than fashion. The other one is nearly done - just the leg binding and snaps left to do. Still, I needed to do something fun to spruce 'em up a bit. The other one was voted by hubby to be video game themed, so I decided to make this one reflect my abject nerdiness personality....

Letter posters with memory verses

I have very fond memories of the cursive letter banner that was posted around the top of the walls in my fifth grade classroom. I thought it would be fun to make something similar for our homeschool classroom (a.k.a. our kitchen). I decided to include a Bible verse for each letter. At this point it's mostly for my own benefit since Miss M doesn't read yet. They serve as great reminders to help her memorize these important bits of Scripture while her little mind is still a sponge. (It saddens me that my memorization skills are not what they were when I was a kid!) The fun part is I saved my work in a pdf file for you to use too! Just click the image above to download the file. I laminated mine before sticking them around my kitchen walls with ticky tacky. (The laminator is a new toy!) Enjoy!
