home No Opt Out | 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. Important Point – To ensure students confidence, make sure that you as a teacher approach this strategy in a cheerful and positive manner, also having this attitude makes them know that you believe that they can do it.

Solid State of Matter These crystals of the mineral pyrite are a good example of a solid. Click on image for full size Courtesy of Corel Solid is one of the four common states of matter. The three others are gas, liquid, and plasma. There are also some other exotic states of matter that have been discovered in recent years. Unlike liquids and gases, solids have definite shapes. The atoms or molecules in a solid are packed together much more tightly in a solid than in a gas or a liquid. Solids are usually much more dense than liquids and gases, but not always. Many solid materials will melt when heated. Crystals, wood, rocks, most metals, and glass are all examples of common solids. Shop Windows to the Universe Science Store!

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. In this article we discuss: What is an experiment? An experiment is a set of measurements that are analysed to test a link or relationship between different things. When writing the method of an experiment, you must ensure that each step of the method incorporates reliability, accuracy or validity. Validity What is validity? Validity relates to the experimental method and how appropriate it is in addressing the aim of the experiment: “Is my experiment suitable?” Several aspects of the experiment can contribute to validity: the equipment, the experimental method, and the analysis of the results. How do you improve validity? Accuracy
A Matter of State A plastic bottle is compressed following a flight Photo Credit: Korte Purpose To help students understand that particle movement changes as a substance changes from one phase to another phase. Context This lesson is designed to give students the opportunity to observe a phenomenon created by particle movement. Prior to this lesson, students should have been introduced to the notion that matter may go through different phase changes. This particular benchmark may be difficult for students to grasp because middle-school and high-school students are deeply committed to a theory of continuous matter. Additionally, many students do not understand that all substances undergo some type of movement. Emphasis needs to be placed on helping students understand that there are different motions exhibited by substances in their respective phases. Motivation Ask students to write descriptions of the three common states of matter. Development Break the class into lab groups of four to five students.

AYUDA PARA MAESTROS 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. Test Procedure Perform the nitrate test using a nitrate-nitrogen test kit. NO3 x 0.23 = NO3-N What To Expect A nitrate-nitrogen reading of less than 1.0 ppm is considered to be excellent. States of matter — Science Learning Hub Anything that has mass1 is made up of matter2 – an all-encompassing word for atoms and molecules3 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 matter4 – solids, liquids and gases5 – but there are two more that are less commonly known but just as important – plasmas and Bose-Einstein condensates. Rights: The University of Waikato Te Whare Wānanga o Waikato Three states of matter Solids, liquids and gases are three states of matter. It is important to understand the particle6 nature of matter. Solid Something is usually described as a solid if it can hold its own shape and is hard to compress (squash). Rights: Foobar, Creative Commons 3.0 Gallium crystal Gallium is an uncommon metal that exists in a liquid and solid form. Right now, you are probably sitting on a chair, using a mouse or a keyboard that is resting on a desk – all those things are solids. Liquid Gas Plasma Lightning
