Amazing Adaptations is an in-class group activity that challenges students to think about how animals evolved their diverse adaptations via natural selection.
Students will study conditions favorable to growing Chlamydomonas, a genus of algae cultured at the Pringle Lab at Stanford University, to determine influential factors related to growth, life cycle, and reproductive rates.
Chlamydomonas is a unicellular bi-flagellated green algae. This eukaryotic protist can be found in lakes, ponds, and oceans.
This lesson will introduce students to the basics of decomposition and microbial soil respiration and how these processes influence the carbon cycle.
Engage students with a demo or video that shows "surprising" polar/ nonpolar differences–use Scotchgard on cloth or paper towel to create a pattern then dip into a colored solution.
Solubility is often taught through the rote memorization of rules and tables.
Students will understand how heat energy can flow from hot to cold while transforming from one form to another.
Fluid motion plays a critical role in regulating Earth's climate, for example through the transport of heat by ocean currents and winds in the atmosphere. The Earth’s rotation strongly constrains the dynamics of these motions and thus shapes how the climate works.
Concerns about access to clean, potable water are projected to rise with the ever-drying climate and increase in global population.
