Minerals Examples

Minerals Examples Minerals Whenever kids get together and play the guessing game 20 Questions, the first question is usually, "Is it animal, vegetable, or mineral?" That's because any native substance on Earth that is not animal or plant matter is referred to as a mineral. Rocks and minerals are often combined into one field of science and studied together, but they each have unique characteristics. Minerals are an inorganic substance that occurs naturally in the Earth, and each one has a consistent and individual set of physical properties like its crystalline structure, its level of hardness, its color, and more. Each mineral has a chemical composition that can be expressed by a chemical formula. Mineral is also used as the catch-all generic term for a substance found on Earth that has an organic origin, like coal, but that isn't a living thing. Examples of Minerals: 1. Geology Minerals found in the Earth's crust include things like salt, coal, iron, ore, shale, and diamonds, just to name a few. While there are a number of elements on the periodic table that can be extracted from the Earth's crust, minerals are often mined as well, hence the similarity in the terms. 2. Nutrition There are a number of nutrients that are vital for living things' growth and function, and many of these are referred to as minerals. Calcium, sodium, iron, zinc, potassium, and magnesium are just a few of the minerals found in a healthy, natural diet, and these minerals support everything from bone growth to red blood cell production. Likewise, plants need minerals too, and depending on the type of plant those minerals and their concentrations will vary. While animals ingest the minerals they need from their food sources, plants will absorb minerals from the soil, which led to the all-important discovery of crop rotation to avoid depleting necessary minerals. 3. Minerals in Food The term "mineral" can also refer to a food additive that makes food healthier or tastier, as in the case of mineral water. This water often contains quinine, a necessary nutrient, and once came from natural springs where the mineral was absorbed into the water. Now, quinine is artificially added to water to produce mineral water or tonic water. Soda water and soft drinks have also been called mineral water in some cultures due to the addition of carbonic acid to produce the bubbly effect.

One-On-One Model Why It Would Be Best Suited For This Digital Age - 550 Words

One-On-One Model: Why It Would Be Best Suited For This Digital Age (Essay Sample) Content: One-on-One Model (Home-school –Tutor) Student Name Institution One-on-One Model (Home-school –Tutor) The One-on-One model is the best education model for the school. The model creates an individualized teaching program where the teacher is assigned a class size of one. The student receives undivided attention from the teacher. The student is able to ask for guidance and clarification on contentious issues related to the subject at hand. Furthermore, the method of delivery is individualized. Each student has unique needs (Bogdan, 2006). They have different rates of understanding concepts. Therefore, the tutor is able to identify a particular student’s needs, and his/her abilities. Knowing this helps the tutor integrate the best method of instruction to help the student grasp the principles easily. The model is student-driven. The instructor is committed to hearing the student and providing feedback. The instructor is more of a mentor in this case than the usual administrator (Falchikov, 2013). The student determines the pace of the instruction. The teacher will only proceed to the next concept if the student has thorough knowledge of the concept at hand. To test the student’s proficiency, the teacher administers random assignments, and/or questions. These are cumulatively compiled to given the final mark of the student. Whether a student passes or fails a class is dependent on his/her final mark (Hossain, 2016). Therefore, the model ensures the student has thorough knowledge of the subject before proceeding to the next class. However, the model is cost-effective for schools. It requires extensive professionals to cater for each student in the school. In this model, the teacher-to-student ratio is 1:1. Considering the number of students in the school, it is going to require massive hiring to run the program in the school. Even if each student is allocated precise times with a teacher, it would take more time to address all the principles for each student to complete the course. However, an appreciable n umber of teachers can be employed by the school. Each teacher will be assigned a given set of students, for example 10 students. The teacher is expected to conduct the one-to-one instruction with each student on a given day. Through this, the model can address the students’ proficiency at a much reduced cost compared to the 1:1 teacher-student ratio. The instructional methods used in this model include the use of video, audiobooks, software and even direct instruction (Bogdan, 2006). Direct instruction would involve telling the student the way forward on a given question, what is expected of him/her and how to go about the question. For example, in a mathematical question, the teacher will explain a step-by-step analogy of the question, only leaving the student to do the calculations and give the final result. The audiobooks and videos provide a real experience of the principles being taught. Students are more likely to understand a concept better when they see a person do i t or even a real-world application of the conce...
