It's a Gas! Or is it?
Oceanography enthusiasts are given a series of thought experiments to consider in order to relate the solubility of gases and solids to underwater volcanoes. It is not particularly engaging to perform these thought experiments. Choose...

How Does Your Brain Respond to Pain?
Zap! Ouch! That hurts! But why? And how come people don't experience or respond to pain in the same way? Take a journey on the sensing pathway, from your nociceptors, along your nerves, up your spinal cord, to neurons and glial, through...

Climate Zones
The climate at the equator is hotter than the climate at the poles, but why? The lesson plan goes in depth, explaining how the angles of illumination relate to the heating rate at different latitudes and seasons. Scholars use a strong...

Photosynethsis....How do we know it's really happening? - Biology Teaching Thesis
Students think of one way to detect photosynthesis in plants besides those ways shown in class. They identify the reaction that occurs during photosynthesis. Students define the difference between an acid and a base. They identify acidic...

Sand Explorations
Students experiment with different samples of sand from Maui leeward and windward beaches. They create a sand map to suggest at least one contributing factor for the formation of each beach sample. They test the samples to determine...
