We all have trouble describing what fireworks do, and are limited to comments like:
"I like how that one did the squiggly thingie"
The Firework Display Designer from i-Board Interactive (I have no idea why it is under the category of Religious Education) gives us (and our students, of course) a way to simply customize and describe a fireworks display to celebrate the holiday. You can make choices of color, "bang," speed, timing and tilt, thus working on important concepts and descriptive skills along the way. Check it out and have a blast this 4th! Computers are certainly safer than real fireworks...
Thanks to InTec InSights for pointing out this resource.
