The Teaching, Learning and Creativity (TLC) model suggests a wide variety of activities in three different phases. In the Teaching Phase, the teacher will discuss, demonstrate key experiments and provide data for pupils to interpret. In the Learning Phase, pupils will analyse text, do a simple test and write an essay. In the Creativity Phase,…

As society becomes more technological, the need for scientific literacy grows . Part of scientific literacy is understanding the nature of science, which can be revealed, in part, by learning the historical context of current science concepts. History of science can be taught using scientific inquiry, scientific argumentation, and authentic…

In a previous article (2014), this author outlined the practical use of visualisation as a way of starting lessons. The purpose of this is to create interest, hold attention, and provide some mental experience of the conceptual learning to follow. In this way, links can be created between the teaching activity in the first few minutes of the…

Many teachers have developed "tried and true" lessons that they look forward to teaching-- mystery powders is one that these authors like. Originally part of the Elementary Science Study curricula in the 1960s, there are now many different versions of this well-known activity in which students examine physical and chemical properties of…

A class activity has been designed to help fourth grade students to identify basic insect features as a means of promoting student creativity while making an imaginary insect model. The 5Es (Engage, Explore, Explain, Extend [or Elaborate], and Evaluate) learning cycle teaching model is used. The 5Es approach allows students to work in small…

This article describes a lesson taught in a designated English Language Learner (ELL) classroom in an elementary school in Pawtucket, Rhode Island, using a sheltered instruction approach. Eighty one percent of the students at this school are from diverse ethnic backgrounds where 25 per cent of them receive ELL services. A variety of languages are…

In an activity sequence that took place over several days, the class learned about sound and how people hear sounds. Following each activity, students engaged in whole-group sharing sessions and individual journal-writing sessions that were designed to help them see the patterns that emerged from their explorations. The activities were carefully…

The 5E teaching model provides a five step method for teaching science. While the sequence of the model is strictly linear, it does provide opportunities for the teacher to "revisit" prior learning before moving on. The 5E method is described as it relates to the teaching of aerobic cell respiration.

In this inquiry-based, integrative art and science activity, Grade 5-8 students use multicolored Epsom salt (magnesium sulfate) crystallizing solutions to reveal beautiful, cylindrical, 3-dimensional, needle-shaped structures. Through observations of the crystal art, students analyze factors that contribute to crystal size and formation, compare…

In the project presented in this article, high school students create and observe miniecosystems in an ecology unit designed around a 5E (engagement, exploration, explanation, elaboration, and evaluation) instructional model. Students choose a wide variety of organisms and use creativity to design miniecosystems. (Contains 1 table and 3 figures.)

Today there are little more of 3 million chemist all over the world producing about 800,000 papers a year. They produce new substances--from some hundreds in 1800 to about 20 million now--the vast majority artificial. This rate is growing quite fast. Once the majority of chemistry teachers all over the world used textbooks as the main (sometimes…

Science education is an integral part of scientific endeavors. When the National Aeronautics and Space Administration was created by an act of Congress in 1958, its charter required the agency to "...provide for the widest practicable and appropriate dissemination of information concerning its activities and the results thereof." Part of that…

Uses simple models to illustrate the principles of this genetic method of mapping gene loci. Stresses that this system enables a practical approach to be used with students who experience difficulty in understanding the concepts involved. (CW)

As science teachers, they understand the importance of gaining student interest to promote learning. They know how challenging it is to spark the curiosity to truly engage students in the processes of "doing science." One often-used method of motivation is the demonstration of science in action. Demonstrations such as "discrepant events". They are…

Provided is a model to depict how the development of process skills can be systematically achieved and in turn determine the students' achievement in science practicals. Modified laboratory instruction is compared with conventional laboratory instruction. The results of field testing on 164 ninth grade subjects are described. (MVL)
