Ideas – mostly inexpensive, mostly reliable
-
Biology
- Experiment – action of lipase on fat. 5ml milk + 5ml 1% lipase + surfactant.
Measure pH over 30 minutes. (Demo or Project). Class: analyse a data file
- Analyse a data file: introductory worksheet on the web for oxygen and light levels in an
aquarium over a week.
- Look at a data file: introductory worksheet on the web for temperature of grass cuttings
over a week
- Demo or project: monitor breathing using a breathing sensor or better - a position
sensor connected to a spirometer.
- Demo: monitor the pulse wave and/or rate using a pulse sensor. Monitor the ECG using a
dedicated ECG unit (retail outlets).
- Use the foxes and rabbits simulator called Creatures
- For work on Genetics look out for a promised Futurelab title (from Nicholl Education)
- Teacher: Illustrate worksheets with diagrams from the science graphics libraries from
SSERC
- Teacher: Use ‘Exampro’ – for setting exams and tests. This database of
exam questions comes from Helix.
- Class: A level revision software (e.g. Swift/Multimedia Textbooks)
- Field trip: Use a data logger to record soil temperature, greenhouse temperature and
light levels over time.
- Field trip: Use a meter-type data logger to take spot readings of temperature, light,
pH, oxygen levels. Use a palmtop or laptop to record and graph.
- Demo: measure pH or oxygen together with light levels in an aquarium
- Demo: use a temperature or pressure sensor to study the reaction of catalase and
peroxide.
- Demo: use a light sensor to study the reaction of amylase / starch / iodine
- Demo/Project: use a pressure sensor to study the osmotic pressure of different
concentrations of solutions.
- Class: use a diet program to model and analyse your diet. Match one persons diet to
another’s lifestyle / age / gender.
- Library: There are multimedia titles for interest and stimulation e.g. Bodyworks (AVP);
BMA Medical Encyclopaedia (Dorling Kindersley); Wide World of Animals (AVP)
- Projects: set students to work with tricky sensors you may have such as oxygen sensors.
- Class: use the Cardiovascular System model
-
Physics
- Demo: Use light gates with a linear air track to measure momentum, kinetic energy etc.
- For work on Gravity see the Futurelab title from Nicholl Education
- Demo: use temperature probes to show radiation from a Leslie Cube.
- Use a distance or motion sensor to study distance/velocity/acceleration graphs with a
mass on a spring or trolleys and ramps.
- Demo: Use light gates to show force and acceleration
- Demo: Use light gates to experiment with ‘g’
- Class: Use the BTL Advanced Physics models covering waves, thermodynamics or mechanics.
- Demo: study a pendulum using a position or distance sensor. Explore velocity, kinetic
energy, damping.
- Class: analyse pendulum motion data. Worksheet on the web.
- Teacher: Illustrate worksheets with diagrams from the science graphics libraries from
SSERC
- Teacher: Use ‘Exampro’ – for setting exams and tests. This database of
exam questions comes from Helix.
- Class: Use A level revision software (e.g. Trotman Screenactive)
- Demo: study current-voltage relationships using sensors – look at capacitors,
bulbs, diodes, resistors.
- Class: explore the addition scope for experimentation using an electric circuit
simulator
- Demo: use a fast response (diode-type) light sensor to show AC ripple from fluorescent
tubes.
- Projects: set students to work with tricky sensors you may have e.g. force, magnetic,
distance sensors.
- Library: There are multimedia titles for interest and stimulation e.g. History of the
Universe (Ransom) Redshift 3 (Dorling Kindersley)
- Waves and Oscillations - 1999 software title with demonstrations and activities from
Fable Multimedia www.fable.co.uk
-
Chemistry
- Roger Frost's "Advanced Chemistry Teaching Tools - 2006 - www.rogerfrost.com/chemistry
- Class: Use A level revision software (e.g. Screenactive)
- Demo: Illustrate trends in chemical properties using the Periodic Table screen in the
Chemistry Set.
- Demonstrate latent heat using two temperature probes
- Class: Analyse prepared reaction rate data using your data logging software.
- Demo: use temperature probes to compare the heat output of fuels / blue flame / yellow
flame. Class: discuss ways of analysing the data
- Demo: study the thiosulfate / acid reaction using a light sensor. Use the sample data
on the web.
- Project: create strong acid / weak alkali titration curves using a pH sensor. Class:
analyse the data
- Admin: see the SSERC Hazardous Chemicals – ‘hazcards’ on CD-Rom from
CLEAPPS
- Teacher: Illustrate worksheets with diagrams from the science graphics libraries from
SSERC
- Teacher: Use ‘Exampro’ – for setting exams and tests. This database of
exam questions comes from Helix.
- Demo: look at an endo or exothermic reaction. Use sensors to quantify the heat of
solution, neutralisation etc – data logging can yield better data.
- Demo: do an acid-base titration curves using a pH sensor and temperature sensor. Note
the heat of neutralisation. Examine the data.
- Demo/Class: use a molecular modelling program such as Desktop Molecular Modeller.
- Projects: set students to work with tricky sensors you may have e.g. conductivity or pH
sensors.

‘AVP’ say they can get most education
titles.
