Pbs Teachers: Scientific American: Beneath the Sea: Light Stick Chemistry

Explore the use of ballast to manipulate buoyancy in submarines by building a model of a submersible using two-liter bottles and balloons. Describe the balance of forces that is responsible for the surfacing and diving of submersibles.

Explore how the brain infers the position of a moving target. Conduct an experiment using a "look-ahead" window to target a moving object.

In groups of three with the lights off and the shades drawn, investigators place inactivated light sticks, in three beakers: one filled with ice water, another with lukewarm water, and the other with room temperature water. They wait...

Follow the path to the sea floor. Pupils play an online interactive board game to reach the bottom of the sea. Participants must match descriptions of creatures to a property of water dealing with oxygen, food, light, or density to move...

Investigate the physical force exerted upon organisms and objects by the environment, and relate pressure to depth in deep-sea exploration. Experiment to discover the impact of pressure on the lungs.

Explore efforts to return parts of the American prairie using controlled cultivation and grazing. Compare and contrast the effects of various levels of ground shade on new seedlings.

Explore the vocabulary and vocalizations in chimpanzee communications and connect them to emotions. Develop and participate in a field study of animal behavior based on observations and interactions with dogs

Explore scientific research saying that continued brain activity may delay or slow the loss of memory function. Investigate and practice different techniques to increase recall.

Investigate the three types of memory: sensory, short-term and long-term, and explore tricks and techniques that can improve long-term memory. Conduct five basic challenges to test, explore and improve memory skills.

Investigate the scientific principles of biospheres, and observe the effects of biological processes on closed systems.
