Unit: WORK AND ENERGY
Where do we and our Earth get most of energy and how do we use it?
Human Ingenuity, Environments
3 months
Work done and Power
Units of work
Energy as agent of a change and mechanical energy is a stored work
Kinetic energy, gravitational potential energy + formulas (Ek = W = F x s, Ek = &frac12; mv2, Ep = mgh)
The Law of conservation of energy
Energy transfer in everyday situations
Efficiency
Renewable and non – renewable sources of energy
Different types of power plants
Give examples of possibilities how can I and my family save energy + argue why it is important
Give examples, describe and explain ways how power plants work and discuss their positives and
negative effects on the environment
Describe how the building of power plants, use of energy sources, development of new ecological
technologies, ... is affected by political, economical and environmental factors
Present scientific information in format of essay, leaflet, oral presentation, lab report, menu, ...
Understand and use scientific language relevant to the topic (work, energy)
Understand the importance of a balanced diet, explain the connection between caloric value of some
kind of food and possible power output of it, discuss the dangerous of anorexia and obesity
Read with understanding the energy bills and information from electrometer, energy transfer diagrams
Discuss scientific information from different sources about energy costs, energy sources and power
plants, use of energy in a household, balanced diet, cars of future, energy “loss”, …
Analyze simple scientific information – worksheets about energy
Explain and apply scientific information about work done, power output, efficiency, kinetic and
gravitational potential energy and energy changes in familiar and unfamiliar way
formulate a simple hypothesis and explain it using a logical reasoning and their knowledge of science,
design scientific investigation and comment on the method and the accuracy of the serults, suggest
improvements to the method - What is my own power output during upstairs running? Efficiency of a
simple machine. Use of energy in our household during 1 day
carry out scientific investigation, work effectively as a member of a team, show respect to the others –
Find my own power output, Efficiency of a simple machine
collect and record data, organize and transform data into tables and graphs
draw conclusions supported by explanation that are consistent with the analysis of data
