Store away from computers and computer disks.

Store with the keepers provided to protect the magnetism.

Magnets can be obtained from old fridge doors, microwave ovens, and speakers.

Magnifiers

Folding

Single lens with handle

  • Scientific suppliers
  • Scientific suppliers
  • Budget retail stores
  Store in a closed box to prevent them causing fire.

(geological, star)

  • Observatory
  • Geological society
  • Identification of land forms, rock types, stars, and constellations.
  • Field trips
 
Marbles
  • Toyshops
  • Budget retail stores
  • Projectiles
  • Pinball-type experiments
  • Fair testing
 
Materials' Safety
Data Sheets
  • Scientific suppliers
  • These sheets provide safety information and properties of substances.
Request data sheets when purchasing chemicals. The supply companies are obliged by law to supply them. (Refer to Safety and Science, pages 38 and 39).

Measuring cylinders
(plastic)

100 mL polypropylene

100 mL TPX/PMP 

250 mL polypropylene

  • Scientific suppliers
  • Measurement of liquids
  • Making solutions
  • Cartesian divers
  • Density measurements
  • Fair testing
Measuring jugs will do the same job.
Measuring jugs
  • Plastic-goods retailers
  • Supermarkets

Meteorological
instruments

Barometer

Hygrometer
 

Maximum-minimum thermometer

Rain gauge
 

Wind speed meter (in km/h, with conversion table):
 

  • Garden suppliers
  • Ship chandlers
  • Stock and station agents
  • Weather
  • Air pressure
  • Humidity
    Temperature
  • Rainfall
  • Wind speed

Meteorological instruments can be borrowed from a secondary school or from people in the community.

A rain gauge can be made from a PET bottle.

Metre rulers
  • Hardware shops
  • Scientific suppliers
  • For measuring length
Metal tape-measures can also be used and are often more robust.

Microscopes

Binocular (stereo)

Monocular

  • Scientific suppliers
  • Universities or secondary schools
  • Binocular microscopes
  • (low magnification) are most useful for looking at small animals, plants, fabrics, crystals, paper.
     Monocular microscopes
     (high magnification) are used for looking at thin sections and prepared slides.

Microscopes can be borrowed.

A class requires at least 2–3 microscopes.

These should be low-powered binocular microscopes (up to 20X magnification is adequate), easy to use, and durable.

Buying microscopes is a good project for PTA funding.

Microscope slides
  • Scientific suppliers
  • Holding specimens for
    examination

Slides can be made using sticky tape instead of cover slips.

Microscope slides are also useful for observing crystallisation.

Microwave

(access only)

 
  • Heating, drying, and
    cooking
 

Mirrors, plastic

  • Plane (150 mm x 100 mm)
  • Convex (100 mm)
  • Signwriters
  • Glass shops
  • Scientific suppliers
  • Light investigations
  • Reflection, translation,
    and rotation
  • Periscopes
Alternatively, use plastic mirror tiles and strips from bathroom supplies or sign writers.
