We had a false start with some crazy quick setting jello, so we started over.\u00a0 We didn&#8217;t get to see the results during lab because the final jello didn&#8217;t set quickly enough (even though we used the quick set method!). It seems to have worked fine in the end, it just needed a little more time in the fridge. I posted the pictures\/results below. We also finished our discussion of macromolecules and made DNA models!\u00a0 We talked about the basic structure of DNA and the components. Making the models really forces you to be clear about which part goes where and how it all relates to each other &#8211; hopefully it was a helpful exercise, and now they have a fun model to refer to (in Module 7 we will talk a lot more about genetics!).\u00a0<br>To work on for next time:<\/p>\n\n\n\n<ul><li>Enjoy fall break!<\/li><li>start reading Module 6, answering the on your own questions as you go<\/li><li>read experiment 6.1 and 6.2<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"768\" height=\"1024\" src=\"http:\/\/garrettcreekacademy.com\/wp-content\/uploads\/2020\/11\/PipeCleanerDNA-768x1024.jpg\" alt=\"\" class=\"wp-image-153\" srcset=\"http:\/\/garrettcreekacademy.com\/wp-content\/uploads\/2020\/11\/PipeCleanerDNA-768x1024.jpg 768w, http:\/\/garrettcreekacademy.com\/wp-content\/uploads\/2020\/11\/PipeCleanerDNA-225x300.jpg 225w, http:\/\/garrettcreekacademy.com\/wp-content\/uploads\/2020\/11\/PipeCleanerDNA-1152x1536.jpg 1152w, http:\/\/garrettcreekacademy.com\/wp-content\/uploads\/2020\/11\/PipeCleanerDNA-1200x1600.jpg 1200w, http:\/\/garrettcreekacademy.com\/wp-content\/uploads\/2020\/11\/PipeCleanerDNA.jpg 1512w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><figcaption>Pipe Cleaner DNA model<\/figcaption><\/figure>\n\n\n\n<h2>Experiment 5.3 &#8211; The Fragility of an Enzyme:<\/h2>\n\n\n\n<p>We had 3 bowls of jello<\/p>\n\n\n\n<ul><li>control: regular jello with no pineapple added<\/li><li>room-temperature pineapple: jello with 1 Tbsp of the blended pineapple added<\/li><li>heated pineapple: jello with 1 Tbsp of heated pineapple added<\/li><\/ul>\n\n\n\n<p>What is our expected outcome?
