Supporting Student Learning in D&T

This blog is designed to encourage students to discuss key topics relating to teaching and learning in D&T.

Energy

IB CurriculumPosted by Steven Daly Sun, April 20, 2014 22:09:57
Please answer the following questions related to the Energy Unit of Work. Each question must be answered by a specific student. The name of each student is next to the question to be answered. Once all the questions have been answered then you must all review the work as you will have a short test on Wednesday 30 April to test your understanding of the material.

Lee-roy - Outline two main types (classifications) of energy (the outline should describe each type of energy and give practical examples).

Sally - Describe how human muscle power was the only source of energy for Craft Production until the industrial revolution.

Daria - Describe how the development of machines based on flowing water led to a revolution in production.

Anuschka - Describe how the invention of the steam engine and the use of steam as a basis for the operation of machines led to a large increase in the scale of production on coal.

Any questions please use the blog to discuss with everyone.

Deadline - Wednesday 23 April.

Please make sure you include the question with the answer on your blog.

Describe how the development of the machines based on flowing water led to a revolution in production

Revolution in production occurred when hand-production methods of manufacture transferred into the use of machined. Machines based on flowing water were one of the first machines ever created. Even though they still used natural resources, had a fixed location and were not as advanced as machines today, they made a revolution in production be significantly increasing possible work load and decreasing time consumption and human effort required.

Outline 2 main types of energy, explain each type and show real world examples.

Out of the many forms of energy that exists, the 2 main types are Kinetic energy and Potential energy. Both Kinetic and Potential are energy partners because Kinetic energy is when their is motion and Potential energy is when there is about to be motion. For example, if you throw a tennis ball against the floor, it bounces up. That energy is Kinetic energy. As the ball reaches higher and higher the Kinetic energy dies down. When the ball reaches its maximum height there is a point in time where the ball isn't moving, that is the transition between Kinetic and Potential energy and as the balls falls again, that is Potential energy coming into play. However when the stall is still on the ground without any movement, both Kinetic and Potential energy levels are at zero.

Describe how human muscle power was the only source of energy for Craft Production until the industrial revolution.

Before the industrial revolution all of the products were manufactured by craft techniques. Which means everything was made by hand. All of the processes, techniques and materials were used by limited tools or technology but mainly used human muscle power, which was available energy source. Usually, axes, ploughs, wagons an carriages, windmills and sailing ships were used for human muscle power. One of the example is that there was labour supply on mining coals and iron.

However, as the industrial revolution starts all of the manufacturing process were replaced by the machines in order to make more production efficient. Because the machines are developing rapidly, it reduced the human muscle power.

Describe how the invention of the steam engine and the use of steam as a basis for the operation of machines led to a large increase in the scale of production on coal. - As stated above in the question, steam is the basic need for the steam machines to be able to work and in order for there to be steam, coal is the material needed for this. Of course, then a lot of coal had to be produced for these machines to get running and as the steam engines increased in production so had to the production of coal in order for the machines to work and for work to get done.
