Warming Things Up with Friction

September 26th, 2016

warming-things-up-with-friction

Today we will be warming things up with friction. We will be rubbing coins against the carpet to see if they get hot. We will be using an infrared camera to see how hot the coin gets after experiencing friction.

Next we will rub our hands together. You will see that the ring on my husband’s hand does not get hot, probably because the ring is tight on my husband’s hand, so the ring got no friction when he rubbed his hands together.

The grand finale is the vacuum cleaner. You will have to watch the video to see how the vacuum cleaner creates a line of heat in its path!

Coin Friction Experiment

Hold a coin against your cheek and see how cold it is. Now rub it against the carpet for 30 seconds. Low-pile carpet works better than shaggy carpet, by the way. Then place the coin against your cheek again and notice the difference in temperature of the coin.

Try different coins: penny, nickel, dime, and quarter. Rub harder or faster and see if the coin gets hot faster.

We measured the temperature of the coins before and after rubbing them against the carpet. We saw an immediate change in temperature, even to the carpet underneath it! We could sign our name in the carpet with the coin, leaving a hot trail on the carpet. This reminds me of signing my name with sparklers on New Year’s Eve.

Hand Friction Experiment

My daughter rubbed her hands together, and they got hotter. This is why if you are out in the snow and you are super cold, you can feel warmer when you rub your hands together, because the friction creates warmth.

I hope you enjoyed this fun heat and friction experiment. I had to laugh when I saw what my face looked like with the infrared camera!

Georgia O’Keeffe Art Projects for Kids

This is the sixth and final week of Mixing with the Masters, and we are creating some fabulous Georgia O’Keeffe paintings. We created the famous “Red Poppy” with gradient painting techniques in acrylic. Our second art project was a watercolor of a delicate tulip, using advanced blending techniques from the demonstration video. Third, we painted a cow skull with mixed media. The background of the cow skull also contained blending and using various tones of one color.

Red Poppy Gradient Painting

Alisha (the video instructor for the course) shows us how to paint this beautiful “Red Poppy” painting, using gradients, or blending the reds into the oranges. She helps us to see the endless variety of color in an enlarged flower. Georgia O’Keeffe painted many enormous flowers and was famous for causing people to enjoy details that were normally hard to see or notice.

You could use a canvas for this project, or you can save money by painting it on watercolor paper. You will want to trim the paper to the size of the flower, if you use the printable template that is provided in the course.

Pink Tulip Watercolor

Alisha taught us how to blend different colors in watercolor, which is hard to do unless you understand that you need to control both the pigment and the amount of water that you are using. Also, if you make mistakes, nothing is permanent, because even dry watercolor can have water added, and then the paper towel can blot it enough that you can mostly remove the color and paint on top of it.

When my daughter shouted that she dripped the wrong color accidentally on her paper, we were able to remove it easily because of Alisha’s instructions.

Cow Skull Mixed Media

o-keefe-cow-skull

Georgia O’Keeffe moved to a desert, so she no longer had flowers to paint. Instead, she saw bones buried in the sand, so she began painting those bones with all their details. One famous painting was of a cow skull, and this is the painting we made with mixed media. We painted gradients of blue in the background the first day. The second day we painted the red and black stripes. The third day we decoupaged the skull shape to the painting with mod podge. I cut the skull out from the worn yellow pages from a book, using the template Alisha provided in the course. We painted on top of the skull, and then we added the details of the skull.

I was astounded by how much detail my oldest son was able to add to the skull! (It’s the first painting in the cow skull picture above.) I’ve been floored by the amount of art skills my kids have acquired through this Mixing with the Masters art class, and I highly recommend it! We focused on six of the most famous painters from history, and we learned their techniques and became even more familiar with their most famous works. My kids have also learned the background of the different art movements throughout history as well as a little about each artist’s life, enough to inculcate a greater love for art!

Prisms, Light, and Color

September 19th, 2016

prisms-light-color

Today we will be learning about prisms, light, and color. We will be doing some hands-on activities to see what light is made of, and what it does. We will also learn why we see colors.

Light is electromagnetic energy. It has different wavelengths that fall on the electromagnetic spectrum. Light is made up of all the colors, as you can see when looking through a prism:

Light illumines the world around us so that we can see it. Light can be reflected, transmitted, or absorbed:

  • reflected: light bounces back
  • transmitted: light passes through material
  • absorbed: light sinks into an object

We conducted an experiment with several different materials and a flashlight, to see if the light was reflected, transmitted, or absorbed by the material. We used a mirror, Cling Wrap, wax paper, aluminum foil, a bench, and my jeans.

Experiments with Prisms, Light, & Color (video)

Take a look at how the prism separates white light into all the colors of the spectrum. Then watch as we conduct an experiment to see which materials reflect, transmit, and absorb light:

Playing with Colors

We printed a coloring page from Christian Kids Explore Physics by Bright Ideas Press, and my daughter enjoyed playing with colors as she painted the scene. She found out that when something is blue, that object reflects blue but absorbs all the other colors.

We had a wonderful time playing with prisms, light, and color!

Picasso Art Projects for Kids

September 16th, 2016

This is the fifth week of Mixing with the Masters, and we are creating several Picasso art projects. The first is with oil pastels, the second with charcoal (mixed media), and the third with watercolor. Picasso was one of the founders of the Cubist movement, where objects are broken up and reassembled as abstract art. Picasso also invented the collage, where various different materials make up the artwork.

Woman with Cap Oil Pastel

picasso-woman-with-cap

The first art project for Picasso was a “Woman with Cap” oil pastel. My children enjoyed coloring such bright colors with their oil pastel crayons, and then going back over it with olive oil. Alissa (the art instructor) provides a printable to transfer onto the watercolor paper to enable your young artists to get the bizarre de-constructed shapes. Is this woman looking to the front or to the side? It’s almost an optical illusion.

I placed the oil in little Asian dipping sauce dishes that my sister got me for Christmas one year.

The Violin Cubist Collage

violin-cubist-collage

This collage was created by gluing old book pages in the shape of the figures in Picasso’s famous “The Violin” collage. The instructional video shows you how to re-create this famous charcoal sketch around the two pieces of book pages.

cubist-drawings-with-kids

My children’s art skills are increasing as Alisha instructs them how to blend and shade this famous artwork. The other charcoal drawing we did in this series was Leonardo da Vinci’s charcoal wing.

I invented my own charcoal and book-page collage. It shows the despair of the soul without Christ, and how His death on the cross bridged the gap to restore our relationship with God and bring us life and joy rather than despair.

cubist-collage

The river is the gulf separating sinners from a holy God. The love of Christ bridged the gap for us by paying for our sin on the cross.

Woman with Yellow Hair Watercolor

woman-with-yellow-hair

Yes, the woman’s skin is supposed to be purple. Picasso was so weird. One of my sons watercolored this “Woman with Yellow Hair” with light purple arms and face, and another chose to go for the darker purple. We changed the color of the shirt from white to “any other color” to make each of their watercolors unique.

I hope you enjoyed our Picasso art projects. In next week’s Mixing with the Masters art class, we will be doing Georgia O’Keefe!
