What is Zones? ‘ZONES’ focuses on developing a child’s self-regulation, including self- control and impulse control. The curriculum’s learning activities are designed to help students regulate their sensory needs, emotions, and impulses to meet the demands of the environment, reach their goals and behave in a socially appropriate way. Students will learn: to recognize when they are in different states called “zones”, with each of the four zones represented by a different color how to use strategies or tools to stay in a zone or move from one zone to another calming techniques, cognitive strategies and sensory supports so that they will have a toolbox of methods to use to move between zones how to read others’ facial expressions recognize a broader range of emotions to gain perspective about how others see and react to their behavior to develop insight into events that trigger their less regulated states BLUE ZONE GREEN ZONE Low state of alertness Regulated state of alertness sad, tired, sick, bored calm, happy, focused, content, brain/body is moving ready to learn slowly/sluggish need to be in this zone for schoolwork/social interactions shows control S of Regulation E YELLOW ZONE RED ZONE Heightened state of alertness Extreme heightened state of alertness/intense feelings N stressed, frustrated, anxious, excited, silly angry, enraged, explosive, starting to lose some control panicked, terrified, elated O not in control of one’s body Z * NEVER REFER TO ZONES AS BEING ‘GOOD’ OR ‘BAD’ * HOW CAN YOU SUPPORT ZONES AT HOME? Know the language o See the attached sheet, “The Zones of Regulation Glossary” Ask your child how they are feeling and what zone they are in o Link their facial expression and their body language to their feelings. For example, “I could tell that you were feeling ‘disappointed’ because you were frowning and your shoulders were sagging o Help your child learn new emotions, not just ‘happy’, ‘mad’ and ‘sad’ Ask your child what triggers them to be in the Yellow or Red zones? o Use the attached “Triggers Worksheet” Avoid asking your child, “What’s wrong with you?” o This is a very negative approach. Ask your child how they are feeling instead Encourage your child to recognize how others may be feeling o While you watch TV together, talk about what zone their favorite TV character may be in Show interest – ask your child what they learned in zones this week o Ask them to share their Zones folder with you o ‘You are doing a great job of staying calm and focused while we visit the library’ Remember, the Red and Yellow zones are not the ‘bad’ or ‘naughty’ zones o All of the zones are expected at one time or another. The Zones of Regulation is intended to be neutral and not communicate judgment Why not create your own Zones traffic signs at home? We can help you with all the emotions – just ask!

Pink-To-Red Coral: a Guide to Determining Origin of Color
PINK-TO-RED CORAL: AGUIDE TO DETERMINING ORIGIN OF COLOR Christopher P. Smith, Shane F. McClure, Sally Eaton-Magaña, and David M. Kondo Pink-to-red coral has a long history as an ornamental gem material in jewelry, carvings, and sculptures. However, due to a variety of environmental and legal factors, the supply of high- quality, natural-color coral in this color range has dramatically decreased in recent years— and the quantity of dyed coral on the market has increased. From a study of more than 1,000 natural- and treated-color samples, this article summarizes the procedures that are useful to identify the color origin of pink-to-red coral. A variety of techniques—including magnifica- tion, exposure to acetone, and Raman analysis—can determine if the color of a piece of such coral is dyed. Although there are limitations to the use of magnification and acetone, Raman analysis can establish conclusively that the color is natural. oral is an organic gem material that has been This limitation has led to the practice of dyeing used for ornamental purposes (figure 1) for pale-colored and white coral into the more highly C several thousand years (see, e.g., Walton, valued shades of pink to red.

What Is the RED Model of Critical Thinking?
1 What is the RED Model of Critical Thinking? Critical thinking includes many qualities and attributes, including the ability to logically and rationally consider information. Rather than accepting arguments and conclusions presented, a person with strong critical thinking will question and seek to understand the evidence provided. They will look for logical connections between ideas, consider alternative interpretations of information and evaluate the strength of arguments presented. Everyone inherently experiences some degree of subconscious bias in their thinking. Critical thinking skills can help an individual overcome these and separate out facts from opinions. The Watson Glaser critical thinking test is based around the RED model of critical thinking: • Recognize assumptions. This is all about comprehension. Actually understanding what is being stated and considering whether the information presented is true, and whether any evidence has been provided to back it up. Correctly identifying when assumptions have been made is an essential part of this, and being able to critically consider the validity of these assumptions - ideally from a number of different perspectives - can help identify missing information or logical inconsistencies. • Evaluate arguments. This skill is about the systematic analysis of the evidence and arguments provided. Being able to remain objective, while logically working through arguments and information. Critical evaluation of arguments requires an individual to suspend their judgement, which can be challenging when an argument has an emotional impact. It is all too easy to unconsciously seek information which confirms a preferred perspective, rather than critically analyze all of the information. • Draw conclusions. This is the ability to pull together a range of information and arrive at a logical conclusion based on the evidence.
