Step 1: Identify the options that illustrate conservation.
Conservation refers to the wise use and protection of natural resources or the idea of maintaining a stable level of balance in any system. It involves not wasting resources and ensuring that they can be used by future generations.
Step 2: Examine each option and determine if it illustrates conservation.
A. Deirdre's belief about the value of coins does not relate to conservation. This is about personal perception of value, not the actual conservation of resources. B. Rebekah's act of recycling her glass bottles demonstrates conservation because she is taking steps to ensure that resources are reused and not wasted. However, not recycling her cell phone batteries might be a missed opportunity for conservation, depending on whether those batteries can be recycled in her area. C. Joseph's decision to brush his teeth in the shower might save energy used for one appliance (lighting in the bathroom), but it wastes water, which is also a valuable resource. Therefore, this action does not illustrate conservation. D. Scott's understanding of equal amounts of pizza, regardless of how it is cut, is an illustration of conservation. He recognizes that the total amount of pizza remains the same, regardless of how it is divided, which demonstrates an understanding of the concept of conservation.
Final Answer
Based on the analysis, option B and D illustrate conservation to some extent. However, option D provides a clearer and more direct illustration of conservation since it involves understanding and applying the concept of maintaining a stable level of resources.
