General Info
All of our activities are scheduled for friday afternoons from 2-4 pm and are held at my home in LaPlata, MD (very near Rt 301 S). These activities are designed with the entire family in mind so everyone (kids, teens, and adults) can participate at their own level and speed. There is no assigned followup or preparatory work, but ideas can be suggested if you desire them.
Feel free to bring snacks for your family to have whenever they need. Any child or adult who needs to attend but does not wish to participate can enjoy the indoors or outdoors in a safe manner until such time as they are ready.
We ask that you pre-register for all SSoMMd activities so that we can have sufficient equipment and be prepared for all the attendees. SSoMMd membership entitles you to a reduced activity fee. There's plenty for everyone to learn and enjoy at our activities, if you want to!
Review of Colors and Chromatography
We had one guest join us for Colors and Chromatography. Here were the activities we accomplished:
- Light Mixing: Into a dark room armed with 3 flashlights and 4 color gels went the kids to explore light mixing. They created cyan, magenta, and yellow. What did they start with you ask? The primary colors of light: red, green, and blue. They had a yellow gel also, but it surprised them by not mixing to make new colors the way they are used to from painting. That's because light mixes additively.
- Marker Mixing: Using regular washable markers and recycled white paper, we mixed and played with red, yellow, and blue to create other colors. Using a standard "kid marker" set, it is pretty hard to get colors which are pure enough to mix well but we did it.
- Colored Pencil Mixing: Do colored pencils work just as well as markers for color mixing? Not unless you press really hard and get solid color over the area. If you color as I normally do with colored pencils, there are still white spots within the colored area which prevent your eyes from accomplishing the trick of mixing the colors.
- Light Separation: Using a prism, we split light into its various colors, looked at the colors from various objects, and examined various light sources. Kids drew what they saw while using the prism (the bending or refraction of light created by the glass material of the prism)
- Marker Separation: We drew pretty pictures on coffee filters with lots of colors and then separated them back out. How you ask? Dip the bottom end of the coffee filter in water and let the water wick up through the artwork. The water will carry the colors along with it. However, each color goes at a different speed. So the colors which make up each marker line are separated out into the primary color components. Try it and you will see and understand better :-)
