Science Week: Day 3

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. See also Day 4 and Day 5.

Welcome to Science Week day three! The rest of the week we will be learning about different types of energy. Our activity today involves energy and heat.

Energy is the force makes things work or change. Heat is energy that makes things warm. Today we filled a mug with steaming hot water. We filled another mug with ice-cold water. Heat can be measured with a thermometer. It was fun putting the thermometer in the hot water and watching the red line shoot up! Our water was very, very hot! It was over 140 degrees Fahrenheit! If you do this experiment, please be careful not to get burned.

Once we recorded the temperature of the water in both of our mugs, Miss M activated some glow sticks. Did you know glow sticks are transparent plastic tubes that have chemical substances in them that can produce light? When the glow sticks are activated by bending them, the chemicals combine and react to make the glowing light that we see!

We put one glow stick in the hot water and one in the cold water. Do you know what happened? The glow stick in the cold water got very dim, but the one in the hot water glowed extra bright! Why did this happen? It's because the energy in the hot water (remember, heat is a form of energy) caused the chemical reaction inside the glow stick to speed up releasing more light.

We activated more glow sticks and put them in the hot water to see them glow brightly! Miss M thinks it would be fun to take glow sticks in the bathtub in the dark. What is your favorite way to play with glow sticks?

Fall SWAP progress

I finally have some progress to report on my Ottobre SWAP. There are actually six garments finished, but I only have pictures of four of them so far. You can see that the brown Maya blouse is lacking buttons. I didn't have anything suitable in my stash, so I'll "have" to go find some at JoAnn's. I'm thinking something to match the medium pink in the trim, but we'll see. I almost never buy buttons...I usually always make do with what I have on hand. The cream Maya blouse is made of a vintage pillowcase I picked up at Goodwill a while back ($0.50). It carries that oh-so-fresh smell that I love on my pillows and is super soft. I have a bit left that I'm going to hoard until just the right project comes up. I'm delighted with how dressy the little skirt came out! It's made of chocolate brown stretch velvet. Miss M thought it was great fun to pet it like a kitten. Modeled by the lovely Miss M...and just before naptime (what was I thi...

Cocoa Krispie Sod House: a model you can eat

Ahh! I just realized I haven't blogged our Adventures in U.S. History since Week 26!! What happened?! We've just been plugging away contentedly at our work and are nearing the end of our school year. So, while I go get myself sorted and whip up the rest of our weekly reviews for you, I thought you might like to see our latest project. A Cocoa Krispie Sod House Ingredients: 6 tablespoons butter 6 cups miniature marshmallows 9 cups cocoa krispies 3/4 cup fancy shredded coconut ("fancy" looks more like grass, but any shredded coconut will work) green food coloring extra butter or cooking spray Also needed: large sauce pan (or large microwave safe bowl) wooden spoon jelly roll pan or cookie sheet waxed paper small glass bowl fork knife clean scrap of cardboard popsicle sticks kitchen shears Directions: Melt butter in a large sauce pan over low heat. Don't let the butter brown! When melted, add in the marshmallows and s...

12-gore denim skirt

The other evening I drafted a pattern for a 12-gore skirt following the instructions found here . The next day I cut gores from worn out pairs of jeans! Now I have a gorgeous denim gored skirt. I used 1 1/2-inch wide elastic in the waist and designed it to sit on my hips rather than my true waist. I’m so short waisted that if I wore bottoms at my actual waist…well, it wouldn’t be pretty! I plan to reuse some of the original belt loops so I can wear a belt with it…let’s just say that a toddler and an elastic-waist skirt are a recipe for disaster! You can see a few places where I removed pockets before cutting my gores – adds character, don’t you think? And a skirt without a pocket is simply ill-conceived, so I reused a pocket from one of Hubby’s pairs of jeans. Now I can carry my cell phone when I run errands!
