Students will experience light energy, light reflection, light refraction, light absorption in five easy set-up stations. This activity is aligned with science TEKS 6.9C. Energy is required by most complex metabolic pathways (often in the form of adenosine triphosphate, ATP), especially those responsible for building large molecules from smaller compounds, and life itself is an energy-driven process. Also, based on results from other studies, birds that eat these fish may have PCB levels at least one order of magnitude higher than those found in the lake fish. What are two statements you can make about energy based on the law of conservationof energy? In physics, work is a measure of energy transfer and refers to the force applied by an object over a distance. Utilizing multiple representations of data as well as understanding the movement of matter and energy through systems are significant concepts in the AP Biology course. The discussion of eCos spinlocks included an example showing why spinlocks should not be used on a uniprocessor system if two threads of different priorities can compete for the same spinlock. It states that energy cannot be created or destroyed; it can only change from one form to another. Students investigate evidence of energy all around themwhen they flip on a light switch, feel a car start to move, or hear a phone ring. (Slide 3) Today we're going to talk about energy transfer. In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics; it starts with identifying different forms of energy in common life scenarios and items: mechanical, kinetic, potential, heat/thermal, radiant/light, sound, electrical, nuclear and chemical. 1 Energy and Energy TransformationsName Date Class Chapter 13, LESSON 2 Energy Transformations Key Concept What is the law of conservation of energy?
