Lesson Title:  FUELLED BY FOSSILS

NC Ref: 

Objectives:    

MK –energy is needed to make things happen; coal, oil & gas are fossil fuels
SK –fossil fuels are from organic remains & take millions of years to form; electricity is not a fuel
CK –how long fossil fuels may last; about energy resources used to generate electricity
 

Lesson outline: 

Starter - Quick quiz - worksheet 

Main –    (a) Target sheet – worksheet 

               (b) Use Summary sheets and P. 102-3 to work on intro to energy r

                           resources. Answer questions 1-7 from these pages, then the planning exercises in the green box 

Plenary – Oral coverage of “You should know…” P. 103   
 

Timings:

Homework Suggestion:  What are the main fuels you use for: heating, cooking, transport

Caretaker: 

Unit No   
 

Lesson Title: 

NC Ref: 

Objectives:    
MK –fuels store energy which is released when they are burnt
SK –fossil fuels are from organic remains & take millions of years to form; electricity is not a fuel; names of different types of energy
CK –
 

Lesson outline: 

Starter - brainstorm – can we remember names of different types of  Energy?

Main –    Practical activity – use worksheets 7Ia/1 or 2. Pupils test range

               of solid fuels. Poss. extension for G+T: design & carry out fair

               test to see effect of different settings of Bunsen air hole.

Plenary – Teacher demo of 1 or 2 liquid fuels

Homework Suggestion: 
 

Resources: 
Worksheets 7Ia/1 or 2
Apparatus from list on worksheets - range of solid fuels, ethanol (+paraffin)

Lesson Title:  FOSSIL FUELS & THE FUTURE

NC Ref: 

Objectives:    

MK –fossil fuels will run out & ways to make them last longer
SK –how fossil fuels are formed, why they are called non-renewable & impact of using less energy on lifestyles
CK – ways of persuading people to conserve energy
 

Lesson outline: 

Starter – Worksheet 7Ia/3 or 4 – work in groups or individually
 
Main –    Making fossil fuels last longer & alternatives. Range of
               Worksheets – 7Ib1 to 5 & 7Ic4 to 8 + Exploring Science P. 104
               to 109.
               Range of possible strategies, I suggest “project” work with
               report back session in lesson 4 (poss extension into lesson 5?)
               Groups working on traffic surveys, alternatives with pros &
               cons, alternative energy resources  - uses + pros & cons. Very
               flexible! Look at resources & allocate to groups most appro-
               privately.
 
 
Lesson 3 Plenary  – where are we now? + set homework
 
Lesson 4 Plenary – Short discussion: Who here can’t do something to cut
               Their fossil fuel consumption?

 

Timings:

Lesson 5 

Unit Title:

Unit No   
 

Lesson Title:   ENERGY FROM PLANTS & THE SUN

NC Ref: 

Objectives:    

MK –the energy we get from food originally comes from the sun
SK –most of our energy resources, including fossil fuels contain energy originally from the sun
CK – plants use energy from the sun in photosynthesis
 

Lesson outline: 

Starter – Worksheet 7Ic/1 (or 2). Introduce methane production as source
               of energy. Set up expt. as demo
 
Main –    (a)Work on the sun as a source of energy for plants (+ intro
 idea of energy flow through food chains); also for most other
               resources. Use exploring Science 7 P. 112-3. Pupils to answer
               questions 1-10 (or 11), possibly draw leaf diagram.
              
               (b) Worksheet 7Ie/1 – suggest we have envelope for each
               working group containing statements on card.
 
 
 Plenary – Take first temp reading from methane expt. Any change yet?
 
 
N.B. TAKE TEMPS FROM FLASKS ON ALL DAYS BETWEEN
LESSONS!

Lesson Title: 

NC Ref: 

Objectives:    

MK –energy is measured in Joules (J), We need energy which comes from food
SK –1 J is the energy to lift an apple onto a table; 1 kJ =1000J; people need different amounts of energy; different foods contain different amounts of energy
CK –
 

Lesson outline: 
 

Starter - temps from methane expt from days since last lesson
 
Main –    Practical activity – use worksheets 7Id/1 or 2. Pupils test range
               of solid foods. A good possibility is to use different types of
               peanut (eg unroasted, roasted & dry roasted) and collect class
results to calculate mean energy content (also to identify &
explain anomalous results). Nuts can be held in tongs & can
often be re-ignited if an unburnt part is exposed!
 
Plenary – What could we use the energy from a peanut for? Leads into
uses of energy from respiration. (Apparently the energy from 1
peanut allows a person to sit reading for 30 mins – as opposed
to lying asleep!) Useless but interesting fact!!
 

Timings:

Homework Suggestion: 
Evaluation of expt. How could you improve the expt

Resources: 
Worksheets 7Id/1 or 2
Apparatus from list on worksheets - range of solid foods (suggest peanuts)
