The integration of language and science education

Introduction
In teaching traditional education, poor English students are usually placed in low ability groups because he believes it is difficult for them to learn to react to higher-level classes with more complex requirements. Integrating language skills in science education has become an alternative to traditional education. In the integrated approach, which has held high expectations of teachers and their students deliberately promotes critical thinking, helping them to university courses.

The science process skills such as observation, prediction, communication, classification and analysis, are similar to the language learning skills of information retrieval, comparison, management, synthesis and evaluation (short, 1991). These skills are important clues to the teaching of science in language acquisition. Motivating and engaging students to talk, ask questions, learn a new vocabulary, and write their thoughts come easily when you are curious, and engaged in the exploration of science or scientific research. Integrating literacy activities in the teaching of science helps to clarify the concept of science and science can do and the most significant and interesting for students.

Instructional Strategy
Studies show that greater student participation and peer interaction to improve the language skills of students best teacher-directed activities (Ruddell, 2004). For example, teachers can use cooperative learning saws where students come to the experts through the texts read or listen, take notes, and teaching peers. Using the cooperative learning offers teachers the opportunity to promote a coherent interdependence among group members to help students in small groups together so that everyone involved in the exchange of information and development of group relations .

Unfortunately, teachers today are many kinds of those who teach science or language do not believe that science and language are interdependent (short, 1991). The language teachers do not meet the language needs of students within the objectives of the subject. They may think that the content of teaching materials is not essential. Similarly, teachers can not understand the content of language issues, or be prepared to use English as a Second Language (ELL) methods for those with little or no experience.

The integrated approach is necessary for language and science to fill the gap that often separate the two disciplines. Students can improve their language skills in teaching science as the context or theme of the lessons. For example, once a scientific subject was discussed and the students shared their knowledge of it, the relevant vocabulary can be taught. Then, some concepts such as standards of grammar or the writing process may be considered by the language or translation activities that are planned (Sherris, 2008).

Reading and writing and teaching content area can be integrated into a lesson or unit, or the approach can be the basis of a comprehensive program. Although the degree of implementation may vary considerably, the principles and procedures remain the same. Instructor who takes an objective of the program area of content, such as science and determines the type of language students need to be able to achieve this goal. As a teacher helps students develop research process science skills, process skills and language learning strategies are both under development. Two key features of the learning process, transfer and the dependence of the tongue, as part of our understanding of the critical issues in teaching and assessment of English learners in science classrooms (Short, 2002).

The integrated approach focusing on promotion of thought and focused on the student teaching approaches. Teachers use a variety of integrated methods of teaching as learning from surveys, cooperative learning, brainstorming, cooperative learning, practical, interactive activities, etc.

As strategies that can be used more frequently in class integrated graphics, demonstrations, and graphic organizers, the development of thought and study skills, and use pre-reading and pre-writing activities. Providing opportunities to use language in meaningful contexts, teachers can facilitate the transition of students  traditional courses (Peyton and Crandall, 1993).

Integrated lesson planning skills
 Teachers should be aware of integrated science learning, language skills necessary for learning and reasoning skills to be manipulated. When necessary, for example, they should give explicit teaching of vocabulary or a business model for the whole class before breaking into small groups. Teachers should encourage students to conduct independent investigations, support students to seek assistance from the other. With this approach, teachers in science subjects sensitive to the language problems that exist in their textbooks present additional documents and to talk about teachers and to recognize potential problems that their students may experience. This approach also helps language teachers, and through a variety of methods used to introduce science real and relevant in the classroom (Short, 2002).
Each lesson should have an integrated component of language and science and the target for the teacher should be to increase academic performance and language skills simultaneously. To develop science and clear performance language, teachers must rely on a variety of resources that include standards of knowledge and expertise in the area of science, standards of proficiency prior to performance evaluations students and teaching materials available. For example, a science teacher to develop an integrated science and language courses, dealing first with the scientific standards to define the concept and the ability to learn, then select the learning objectives, assignments and materials appropriate for students as determined by assessments of student performance.

Deal with the practical integration of reading, writing, listening and conversation, teachers must identify and work with students in two-one conversation skills specific object, the other general. Teachers then provide students to improve reading in all four sub-language, writing, listening and speaking, in many kinds of texts, including some specific to their subject matter and others, which are common (Aronson et al 1978) . Examples of speech are contained in experimental studies, surveys and interviews. Those tend to be a summary, comparison, and contours.

For example, plans to teach movement, the teacher can design a possible solution to the following statement: Students will be able to observe and calculate velocity and acceleration of a moving object, discuss ways to measure the distance and write a summary of each method. 
Calculate, discuss and write is descriptive verbs, which determines whether a particular performance includes the knowledge and skills in a field of science or specific language features. Observation and calculation of velocity and acceleration to describe the scientific results, discussing and writing about the methods used to compare types of distance measurements describe language performance in science. Teachers should consciously integrated attempt to separate descriptive verbs used in standard documents and materials are identified separately by language and content performance.

According to Vin (2008), an integrated educational plans are at least two benefits. First, teachers are in different objectives and content of language teaching, which can improve the delivery of their teaching. Secondly, if these objectives are clearly set out and then again for each lesson, students become aware of different content and goals of language that would enable them to manage and monitor their own learning.

Students also develop the ability to perform other tasks related to the content, such as laboratory experiments, the creation of scientific calculations, and for historical research. Solve problems, evaluate solutions and collaborate effectively with any of these activities by using appropriate language.

Integrated Lesson Plan
Lesson planning is crucial for both the student and teacher success. The best learning takes place in the design is to generate lessons that allow students to make connections between their knowledge and experience, as well as new information is taught (Rummelhart, 1995.) Effective in teaching specific content objectives, which identify what students should know and be able to do is to guide the teaching and learning. For English students, but the targets of the lesson is simply stated, both orally and in writing, and are tied to specific content standards grade-level (Echevarria and Graves, 2004). Because the contents of the aims of objectives of language must be stated in clear and simple, and students should tell them, both orally and in writing.

The Integrated Science lesson plan guidelines (see table below) describes the phases of instruction in the lesson plans and integrated science courses are more effective with ELL are language objectives and content. How students learn science, both in processes and English language skills, may be reviewed independently of scientific explanations and logical reasoning to communicate. skills of higher order thinking, such as the articulation of expectations or assumptions, stating the findings, which summarize the information and make comparisons, may be linked to the objectives of the tongue.

What is a Science Kit?

A science kit is essentially a toy or a toy collection for children, but scientists! What do we mean by that? Well, compared to a doll or toy car, for example, a kit of science is a science project or a project group consisting of hands on experiences that often result from a fun toy Science. science kits, such as those sold by the store of Science for the Stars, are presented in an easy to understand and interesting way and are designed to teach children facts about different scientific topics. For example, Crystal Radio kits are very popular and consist of a project to build a crystal radio. While working on this project, children learn about electronics and electricity, and how the role of radio.

When they have finished, have a really cool toy that works! Or take "How and why years of Science Kit Educational Analysis", which has extensive experience in various disciplines, including biology, ecology, astronomy, among others. Children can learn why the sky is blue, why it rains, how to bend light and conduct experiments similar to those of real scientists who discover many secrets of the earth. As you can see, a science kit is infinitely better than a toy for children regularly. Not only do children use their imagination, but they learn real science to help the school and the real world. When you begin to understand how the world around you really works, you start to think differently. Instead of just accepting things as they are, you become curious as they begin to ask questions, and realize that there is reason and logic in the world around us.

It's never too early the child begins to learn the science and the elderly are the best teachers! If the child asks the moon, you just answered: And the Moon? Or you can say the moon was committed to gravity, causing waves in the sea, and reflects the sunlight? Children are an incredible memory and keep information on their parents better than anyone, and if you give them a kit of science to learn these things, eaten with a spoon. Most learn early in life, the easier it is to school and when they get older. kit science books and science pilot undoubtedly the best way for children to learn science.

It's well known that children learn the concepts and skills more quickly, store more, and have fun while learning with practical experiments rather than just read about them in books. Science kits are designed specifically for these tests and may otherwise boring topic new and exciting. Built directly into the real science teaching kits. They are designed, created and written by teachers, researchers and other professionals from different disciplines and will include national teaching standards. Science kits are also good sources for science fair project ideas.

Kit science can be used at home working for one or more children. They are an excellent way for teachers to explain scientific concepts to students and parents who are very home-school children and want to spice up the curriculum. How many adults love crosswords, Soduko, and other mind challenging games? Well, the boys want to be problem solvers also active in science and engineering series perfect for a great imagination and creativity take directly to the experiments. And if your child is becoming a science, you can be sure that science will find a kit to cover it. It's a good way to get children interested in science!

Science kits tend to use studies of real life, so that children will think about what they have learned and apply it when they go outside to investigate, or while they are in the classroom. If the car is not already covered what is necessary to create 'studies', you just need some common household materials, and sometimes the batteries. Overall, a science kit to teach children science concepts, they may apply to the world around them and help them to "think outside the box"

The fact that science is increasingly neglected in schools and American children fall further behind the rest of the world scientific knowledge. Most schools, public and private, have now suggested reading lists summer recess. Viewing science books and kits to test the same way and allow children to promote the theme of science. They are prefect for birthdays, holidays, or if you are feeling generous all year. And, science-learning-fun!

An Introduction to Evolution

Evolution is change over time. Under this broad definition, evolution can refer to a variety of changes that occur over time—the uplifting of mountains, the erosion of riverbeds, or the creation of new species. The term "biological evolution" is a more specific type of evolution. Biological evolution refers to the changes over time that occur in living organisms. Biological evolution is defined as descent with modification.
Biological evolution occurs at different scales. These include small-scale evolution and broad-scale evolution. Small-scale evolution, also referred to as microevolution, is the change in gene frequencies within a population of organisms changes from one generation to the next. Broad-scale evolution, also referred to as macroevolution, refers to the progression of species from a common ancestor to descendent species over the course of numerous generations.
