I've only scratched the surfaces here; mainly idea fragments & initial research.
|Item||Lab investigation||Brief description||Features|
|1a||Molecules made manifest||Explorations demonstrating H-bonding, polarity, hydrophobicity: weird properties of water... that drive life as we know it||water, oil, surface tension, charge|
|3||pH: the Power of Hydrogen||Make pH real by having students develop tools and taste the rainbow||Colors with cabbage;
magic lemonade with miraculin
|5||Tabletop photosynthesis demo: O2||Link goes offsite to wonderful 'Exploring Life' page
We developed an extension using food coloring to filter light to test photosynthetic efficiency of different wavelengths; 'one day' I'll post it!
|photosynthesis, oxygen, protocol|
|7||Milk, food coloring, detergent||Besides being utterly cool, this one isn't about surface tension. Students should be able to demonstrate differences; can they then reason them out?|
|7||Daphnia||I've only cultured them (they're robust!), but there are accessible hemoglobin & evolution ideas||Resources|
|11||Balance bands||Enabling students to discover experimental design, controls||PowerPoint|
|9||Pineapple chunks vs. milk, jello||You may know that a pineapple chunk will 'eat into' jello; this is a demonstration of enzyme activity. A more faster & more rigorous response can be set up by using milk instead!||Procedures|
|50||Evolution in a bottle||Leave a bottle of Pseudomonas on the counter for a few days and you'll reproducibly evolve a mutant form that takes over the surface...||References|
|100||Read, think, discuss||While these aren't 'hands on' activities in the sense of getting wet & messy, many are active, engaging 'minds-in' research-and-discuss activities||Resources|
