An LED lightbulb

    You hear the click of the flashlight as you press the black button on the yellow flashlight. A straight beam of light shoots of and hits the wall, making it glow bright yellow, changing the glow of the house from black and casting a yellow atmosphere in it.

My happy face when we got the LED lightbulb
to light up.

    But what's the science behind the click? After all, it may be easy to press the button, but hard to understand the science behind it. That's what we learned a few days ago, on Monday. When we went down to the science lab, we grabbed a box with an index card, foil, a round battery, a LED lightbulb, and a piece of tape. We had to use all of this to construct a flashlight, or some thing that could light up when we pressed it, at least. Foil is a conductor of electricity, and we can use the foil as a wire.  Because of that, I cut a small strip of foil and taped it to the long end of the led lightbulb, which was the positive end. Then, I cut another small strip of foil and taped it (lightly) to the negative end of the lightbulb, which was the shorter end. After that, I pressed the foil harder so it would light up. And it did!

    From this activity, I was able to learn about how flashlights work, and was able to build one (that you can't really hold easily - lol). This is the world of wonders, and this is the perfect time to discover it.
