Nelson Thornes - Technical Director
1 Nelson Thornes - Plant Problems
Nelson Thornes is a publisher of children's educational books, who were looking to compliment their range of A-Level science books with eLearning multimedia. As technical advisor the creation of illustrated detailed plans of how each multimedia module would be created were submitted for subsequent build by Nelson Thornes development team in india. For more complex modules such as the Mobile Phones module, elements of working code were also submitted to assist in production.
Plant problems Dealt with the various factors that aid plant growth, and also noted the financial difficulties relating to artificially recreating these conditions in a controlled environment. This helped children develop a sense of what could be economically achieved to get a better yield of crops.
2 Responding to Change
This tool illustrated how the human body responds to impetus by following a signal from its start right through to its end result.
3 Energy Losses
Children were encouraged to design their own fantasy creature...would their creation be heat efficient? how much would it need to eat to survive? These questions would be prompted by the teacher and the multimedia, allowing students to develop their own sense of what contributes to homeostasis and energy use in animals
4 The Human Kidney
Taking a closer look at how the human kidney works. The user can focus on various sections of the organ and see how different sections remove different undesirable particles of food.
5 Exchange in the Gut
Shows how food is absorbed in the gut and what factors (such as overall surface area and and active transport system) aid its function.
6 Mobile Phones
Demonstrates that electromagnetic radiation is all around us, and also illustrates how reception in mobile phones works. Signals from various base stations are received by the phone, which then decides which base station to receive data from. The signal can be blocked by terrain such as mountains or cities.
Working code was submitted to aid the development of this multimedia
Analogue and Digital Signals
This demonstrates a signal sent through both digital and analogue transmission. the interference of the signal is shown on the screen and can be heard through the speakers. Both signals are seen to have noise on them, but the noise is only heard on the analogue signal. Students can be encouraged to find out why this is.
9 Nuclear Reactions
Background radiation is all around us. Should we be worried about it? Where does it come from? This simulation allows a user to move to different situations (work,home, countryside) to see the amount of radiation in those locations and where it comes from.
10 Electromagnetic induction
How can kinetic energy be turned into electrical energy? This tool covers the basics of electrical dynamos and teaches the basics of electromagnetic induction, and Fleming's left hand and right hand rule.
It's interesting to note that Scotland's syllabus teaches (arguably correctly) that electrons flow in the opposite direction to what is accepted by the rest of the world, so provisions for the left and right hand rules to be switched were made.
