Coleman's Camp - Weekly Journal Entry: 3/4/2013

Week of 3-4: This week it was time for the Thursday group to revisit and re-explore a previous Coleman's Camp session, dry ice!  They took their previous investigations of dry ice and were able to replicate experiments and manipulate the variables they now understand.  They could vary the temperature of the water, use the liquid dish soap more sparingly, and knew how to get the empty 35mm film canisters to explode with maximum force!  Everyone had certain attributes of dry ice they wanted to focus on, and we took many photographs of their results.  The Saturday group created bases, lairs, jet backpacks, and other buildings from basic cardboard boxes.  We learned how to utilize our creativity and imagination to take boxes and transform them into accessories for the types of toys each kid plays with at home.  Some wanted a car bay for storing Hot Wheels; others wanted a Batman type base for action figures.  We worked to primarily use the boxes and any pieces cut from them to make doors, windows, ceiling pieces, walls, walkways, etc.  We then used a glue gun and paint to finish off the boxes.  My son Beckett brought in toys from our van and kids were able to test out their creations in imaginative play.

Coleman's Camp - Weekly Journal Enrty: 2/4/2013

Week of 2-4: This week it was the Thursday group students who were able to experiment with dry-ice.  They observed sublimation in action, created the eerie fog with warm water, and created many bizarre and alarming sounds with different types of metal items pressed against the dry-ice.  We discussed the hazards of dry-ice inhalation as well as the effects of rapid and extreme freezing of human skin when in direct contact with the sub-zero material.  The kids were especially excited by the use of 36mm film canisters that, when filled with dry-ice and capped, would build pressure as the dry-ice sublimated until the lid would explode off, usually hitting the ceiling.  I am sure the library patrons were alarmed at any screams they could overhear, it was amazing!  We also mixed in dish detergent and created dry-ice bubbles that looked like ever-expanding masses of brains or worms.  When grabbed or picked up and squeezed, the bubbles would burst leaving small clouds, a peculiar effect.  The Saturday group created Valentine's Day cards for parents, practicing brainstorming, reflective and authentic writing, rough draft correction and editing, and then writing the final nice copy.  The kids assembled a foam dog and added unique details.  The notes to their parents told of their favorite activities to do with their family.  The finished products looked fantastic!



Coleman's Camp - Weekly Journal Entry: 1/28/2013

Week of 1-28: With the state assessments looming and classroom preparation increasing, the Thursday group took a humorous look at test situations and irreverent answers to worksheet questions.  We discussed the stress that can often come from state assessments and how teachers share in those feelings.  We watched two clips, one of Mr. Bean taking an exam and another from Spies Like Us where two agents try to cheat their way through difficult tests.  We then reviewed a packet of samples I have collected of hilarious student answers on worksheet and test questions, then creating our own.  The Saturday group conducted dry-ice experiments to learn about sublimation (the change from a solid directly to a gas, skipping the liquid state).  The students also had hands-on experience with making metal objects vibrate and make noise, creating eerie fog with warm water, and other investigations.
