If you’ve ever made your own tie-dye shirt, you know that it can be a real mess… especially if you’re using the right chemistry to make really vivid looking shirts. While I’m no tie-dye expert, I learned from three people who used to travel with the Grateful Dead (well, they followed the Dead from gig to gig and sold their tie-dye apparel to the pickiest of Deadheads). The secret to making amazing tie-dye shirts is to use fiber reactive dyes.

The teachers and parents at Wilder Elementary in Littleton, Colorado reward each graduating 5th grader with the opportunity to make their own graduation tie-dye shirt. I joined the kids last week at school to share the science of tie-dye and to help them create a one-of-a-kind shirt.

Lots of kids learn how to do tie dye, but the fifth graders at Wilder Elementary got a dose of art and science today when yours truly and art teacher extraordinare, Jill Day, approached the activity from a slightly different angle. You won’t find the science of tie dye in the fifth grade curriculum, but today’s lesson was both a gift from the Wilder staff and PTO and a rite of passage as these students move onto middle school. From the science perspective, the students learned about three “secrets” of tie dye, and on the art side, Mrs. Day covered the coolest way to use colors in a tie dye pattern.

In addition to washing their tie dye t-shirts tonight, the students were invited to share some of the “secrets” they learned and some of the finer points of learning the “real” tie dye methods (as one of the students said, “Direct from the tie dye hippie artists to our classroom!”) The students will be posting their comments all night long… check back tomorrow and we’ll even have some pictures and video up on the site.

Only a very cool teacher gives this kind of homework to her students… “Using only construction paper and tape, I want you to design a rocket.” Lisa Heaton, the Gifted and Talented teacher showed her students a specially designed rocket launcher made out of PVC plumbing parts from the local hardware store. The idea for the PVC rocket launcher comes from U.S. Space Camp for Educators curriculum. I had the privilege of assisting Mrs. Heaton with the launch of the paper rockets. As the students will share in the comments below, the first launch revealed their design strengths and flaws. The five students with the best launch served as mentors for the rest of the students as they returned to the classroom to repair and redesign their paper rockets. The second launch proved to be the real learning experience - be sure to read comments from the young rocketeers below.

“This rocket launch activity coincides with the students reading Rocket Boys (also known as October Sky) by Homer Hickam. I want these kids to experience first hand the feeling of failure and success through the trial and error process of building their own rockets… and this air-powered rocket launcher does the trick,” says Lisa Heaton as she turns to help a 5th grader repair a rocket that didn’t fair well during the first launch.

These 5th graders are also using this hands-on science experience to learn about the science of blogging (pun intended). Student bloggers from Mrs. Heaton’s class in past years posted blog comments about their rocket experience that were even read by Homer Hickam (the author of October Sky) himself. Be sure to read the student comments below.

The students at Wilder Elementary in Littleton, Colorado proved that Mom is right, “Wash your hands with soap and warm water!”? The third grade class did an experiment using Petri dishes prepared with agar (a seaweed derivative). Agar is an ideal “food”? source for the bacteria. The students collected samples around the school including on top of the tissue box, door knobs and more. You won’t believe what they found growing in the common areas that we all touch. They also tested how well common cleaners eliminated the bacteria.

The students also learned how to properly handle the growing bacteria. Always seal the Petri dishes and throw them away when you are done. The teachers had the students take pictures of the dishes, so they could refer back to their findings, without having to store bacteria that can make them sick.
