Tuesday July 7th, 2015

Second day of camp: we had to review a few of our basic class behavior and kitchen safety rules with the class today, which took away some of our experiment time. Fortunately we had some set backs that gave us more time; the Taste Test experiment took a bit longer than anticipated, and the red jello mix for the laser experiment did not set in time. 

We improvised our lesson plan and will complete both the Pineapple Enzyme and Jello Laser experiments Wednesday July 8th, 2015. We'll go over our basic class rules and kitchen safety rules again on Wednesday. 

Review

• Refresher on rules and expectations 
• Review of safety items 
• Review of Monday's experiments 
• Today's experiments 

Icebreaker

Taste Test Experiment

• Challenges students senses and gets their gears churning for science!
• Students were blind folded to heighten their sense of taste. The students blindly tasted ten different test samples including: mushrooms, red bell pepper, yellow squash, Fuji apple, green bell pepper, walnuts, avocado, silken tofu, banana, and dark chocolate chips! 
• Students documented their results and we reviewed the results after class. 
• Conclusion: our students have GREAT taste buds! 

Pineapple Enzymes Experiment

• Demonstrates how the protein in gelatin and bromelane enzymes in pineapples don't mix. 
• Mixed the gelatin packet, with 2/3 boiling water and 1/3 cool water, until all the powder dissolved. Divided mixture into two different bowls; one regular mix, one mix with pineapple chunks. Set both mixes in the freezer to try and decrease setting time. 
• Plain mix almost 100% set but not enough to stick to the bowl. We'll let the mix set over night and review the final results tomorrow in class. 
• Started our predictions worksheet and discussed student's hypothesis. 

Laser Jello:

• Demonstrates how light passes through different materials.
• Mixed the gelatin packet, with 2/3 boiling water and 1/3 cool water, until all the powder dissolved. Set mix in the freezer to try and decrease setting time. 
• Mix did not set; class discussed their hypothesis on why the plain gelatin set faster than the red). We'll let the mix set over night and complete the laser experiment in class tomorrow.

Review of class lessons 

Discussed the Taste Test experiment and spoke with Mrs. Iris about our favorite samples.

Looking ahead to tomorrow's lesson

We discussed how our jello experiments will be completed tomorrow and that we should have time to start our original Wednesday experiment dealing with starch!
