"This is just like being a real Scientist!"
First, students carefully make observations prior to the reaction...anticipations builds! Next, as instructions are given, the plastic vial holding the red liquid is squeezed onto one side of the plastic zip-lock bag...woah...a vivid color change...double woah...this side is HOT! Then, as further instructions are given, the remaining red liquid is introduced to the other side of our reaction vessel...yikes...another vivid color change...double yikes...this side is FRIGID COLD! Finally, all ingredients are squished together...but the results of the rest of the reaction will remain a surprise...and an exciting surprise, indeed!
This classic reaction is such a wonderful experience for young learners to make scientific observations, view evidences of chemical changes and record their findings on age appropriate worksheets!
This safe, non-toxic and easily disposable hands-on experience maximizes excitement and minimizes any hazards. Although the substances involved are common and safe, rest assured, the contents of the reaction never leave the zip-lock bag!
Similar to every "Amazing Chemistry Show" Hands-On Experience, a seven foot tall brightly colored pull-up tension banner adds to the excitement during exploration and observation!
