Light Unit Art Integration!

If you ever want to give kids a project that they are so excited about that they are daily pestering their homeroom teachers to know if it is an Art day, this is it.

Oooh. Aaah.
Presenting, Magic Wands in grade one, a lesson on integrating Science and Art; a lesson that brings the science to the art-minded and art to the science-minded in equal proportions.

An aside: 
The truth is, I was afraid of science for a long time. It said it wasn't "my thing," but really, I was scared because I didn't understand it. Very few teachers along the way presented science to me in a way that made me feel motivated or confident. So, if you are an art teacher reading this, and you are feeling scared of the science in this lesson too, hang on. I gotcha, and we are going to make this okay.  You will love it. You will learn along with your students. That it isn't just "okay" for kids to know you are learning too- it's actually awesome and brave to model life-long learning.

Back to the project:
The first graders have a comprehensive light unit. For the most part, this is a part of science that we art teachers actually do feel comfortable talking about. The light unit covers shadows, light sources, and how permeable different materials are to light.

So that was where we began in the Art room, while during the homeroom science time they did work on the same area. On the white board I wrote the above vocab words, then students sorted materials using a flashlight to see how much light came though- none, some, or all. Students tacked up those materials under the word they felt was a best fit.

Here is the part which, until a few years ago, I found intimidating: How would we turn on our own lights to explore? Circuitry can seem mysterious, but it is actually pretty straightforward, enough even that my first graders can tell you the basics now.  So can this fabulous dynamo celeb kid, Sylvia. To listen to her explain electrical circuits in just a couple of minutes, watch this video, beginning at 3m15s.

Here is how we made our circuits: Hang tight, you can do it too!

Red/Green/Blue LED
This tiny light bulb is a slow color-changing LED, which rotates colors by having red, green, and blue bulbs inside. Here is what they look like in action:

 I purchase mine directly from China on eBay. They are marvelous, and they cost $5 for 100 pieces.  If you look carefully at the photo above, you can see the legs of the LED, called leads, are twisted around a piece of wire. I did that part for the kids, because little fingers have a hard time making that strong connection. It helps that I soldered this connection as well, but you don't have to- twisting them is enough. I attached black to the negative (short) lead of the LED, and red wire to the positive (long) lead.
This is what it looked like- two wires, around 12" each, twisted to an LED

The other thing kids need is a battery. I use a standard button cell, coin-type battery, but don't use those with kids younger than kindergarten, or children with special needs. They cannot go into mouths. These came from, and cost about $0.20/each.

On the first day, the kids spent time with those two objects, just exploring what they might be. The class' thoughts that first day were amazing to hear, as they helped each other investigate ideas:
It's a little light, maybe.
I think this is a shiny magnet that stops the light from turning on.
These are batteries, I think.
Yeah, put it against the metal I think.
It's not turning on. I think it should turn on.
Twist it like this.
No, you don't have to twist it.
If I hold the the wires really hard I can make it blink!
Put the black wire on the not-word side and the red one on the word-side of the metal thing.

That's all there is to it. The black touches the negative side of the battery, and red touches the positive side of the battery. Pinch it, and it lights up!
If you have got this far, you are golden. Tape the LED to the top of a stick or dowel, and wrap the wires downward, as in this photo below. Kids taped the black wire to the negative battery side, and left the red wire free to be the off/on switch.

Make sure to tape the battery and black wire to the dowel, leaving part of the positive battery side exposed. Turn it off and on by pressing the red wire under your thumb, and then releasing the pressure. That is your pressure switch!

Now, make that thing look a little more magical. Class #2: Wrap it in yarn and cover that wire! We leave the battery uncovered so that kids can troubleshoot if their tape comes loose.

In class #3, we experiment with transparent, translucent, and opaque materials to make a cover for the bulb. In the photo above, the student wrapped clear tape around her fingers (sticky side out), and stuck it into foil confetti in the shape of stars and moons. She slid it off her fingers and taped it on right around her LED, wrapping it again in tape to hold it in place. It is both translucent (the tape) and opaque (the foil pieces).

The top of the ones above and below are made of tin foil, which the artists poked holes into it to let the light out, as foil is opaque. It's pretty nifty, because when it is on, it casts little dots of light.

Did you see those feathers and flowers and tulle? These artists really went to town on the opportunity to make theirs look magical!  Here are several more beauties- this is a great place to explore making the wands extravagant with feathers, fake flowers and leaves, your best ribbons, etc.

Surely for a wizard of the forest.
One important thing to know is that when you send these home, include a little warning/educational note about the small parts and battery. You can never be too cautious, honestly, and they still look lovely.

Here is the note up-close:

One of my groups takes theirs home TODAY, just in time to add some serious wow to their Halloween costumes. These students are suddenly finding themselves the envy of every older kiddo in school, who are asking, Can we go back to first grade?! 

Happy magic-making!
