Questioning Techniques for the Classroom
No opt out is an all or nothing strategy that requires the students to answer questions that are asked of them correctly. Incorrect or partially answered questions should be corrected by other students who have their hands raised, continuing until the right answer is given. If an incorrect answer is given then that student will continue to be asked questions until a correct answer is given. Student Who Refuses to Try – If a student replies I don’t know or I don’t want to answer, turn to another student and ask them the same question, once you achieve the correct answer from another student, turn back to the first student who could not answer the question and ask them if they can answer now.

The three others are gas, liquid, and plasma. There are also some other exotic states of matter that have been discovered in recent years.
Validity vs Reliability vs Accuracy in Physics Experiments
Introduction to Validity, Reliability, and Accuracy of Experiments Practical assessments are designed to test your practical skills: how well you can design and carry out an experiment and analyse results, but also your understanding of the purpose of the experiment and its limitations. One aspect of this is the reliability, validity, and accuracy of the experiment.

Nitrates
Background Information Nitrogen is an element needed by all living plants and animals to build protein. In aquatic ecosystems, nitrogen is present in many forms. It can combine with oxygen to form a compound called nitrate. Nitrates may come from fertilizers, sewage, and industrial waste. They can cause eutrophication of lakes or ponds.
Elements & Periodic Table
Now we're getting to the heart and soul of the way the Universe works. You know that a generic atom has some protons and neutrons in the nucleus and some electrons zipping around in orbitals. When those pieces start combining in specific numbers, you can build atoms with recognizable traits. If you have eight protons, neutrons and electrons, you will have an oxygen (O) atom. If you have seven protons, neutrons, and electrons, you will have a nitrogen (N) atom. The atoms for each element are unique, even though they are all made of similar subatomic parts.

Vital Signs – Climate Change: Vital Signs of the Planet
An example of a temperature anomaly is how much warmer or colder than the long-term average a unit of time something is (like how much warmer than average the most recent year was globally). This graph illustrates the change in global surface temperature relative to 1951-1980 average temperatures. Nineteen of the 20 warmest years all have occurred since 2001, with the exception of 1998. The year 2016 ranks as the warmest on record (source: NASA/GISS). This research is broadly consistent with similar constructions prepared by the Climatic Research Unit and the National Oceanic and Atmospheric Administration.
Matter: Properties
Global rating average: 0.0 out of 50.00.00.00.00.0 Find out how properties of matter describe its various states. Discover the states of matter that exist on our planet and in the universe.
Sea Surface Temperatures
Key Points: 1. Changes in sea surface temperatures reflect the overall warming trend in the climate system and, in turn, influence weather and climate patterns worldwide. The bars on the graph show the number of degrees by which the average sea surface temperature for each year differs from the average sea surface temperature during the last century. 2.
States of matter — Science Learning Hub
Anything that has mass is made up of matter – an all-encompassing word for atoms and molecules that make up our physical world. We describe this matter as existing in states (sometimes referred to as phases). Most people are familiar with three states of matter – solids, liquids and gases – but there are two more that are less commonly known but just as important – plasmas and Bose-Einstein condensates. Three states of matter Solids, liquids and gases are three states of matter.
