This activity will help students understand algal blooms. They will devise their own experiments to test the effects of nutrients on algal growth, or younger students may follow the steps outlined in a sample activity which is provided. Students will be reminded that they need to have controls and replicates in their experiments. As a result of this activity, students will come to understand the requirements ... Full description.

In this lesson, students will investigate absorption, reflection, and scattering of light in the deep sea and discover the concept of bioluminescence. As they proceed, they will learn that white light (visible light) is comprised of all colors of the spectrum, that the quantity of light decreases with increasing depth in the ocean, the quality of light changes with increasing depth, and that red light ...

In this activity, students observe nutrient depletion as they germinate and grow nutrient-demanding seedlings. They will discover that all plants require nutrients to grow and thrive and that these nutrients are found in the soil and absorbed through the plants' root systems. They will also learn that nutrients are dissolved in water and are distributed throughout the plant via its circulatory system; ... Full description.

Salmon Homing Instincts is an activity that enables learners to experience what it is like to be a returning salmon attempting to find its home by smell. Scientific research suggests that salmon use the smell of water to find their home stream; even after being out in the open ocean as many as six years. The activity allows the entire class to participate in the life cycle of the Pacific salmon and ... Full description.

This activity will offer students an introduction to chemiluminescence and bioluminescence, an opportunity to observe the effect of temperature on reaction, and an activity that integrates art and science. Students explore how the temperature of the chemicals that combine affects a chemiluminescent reaction. They will also learn that since solar radiation does not reach the ocean depths, the bottom ...

This activity will allow students to observe and interpret fossil footprint evidence. From the evidence, they are asked to construct defensible hypotheses or explanations for events that took place in the geological past. Students will be asked to propose explanations and make predictions based on evidence, recognize and analyze alternative explanations and predictions, understand that scientific ... Full description.
