| Here is a measure of which sensors and how many you might need |
| For general science age up
to 7
|
Leave this age group for the present. |
| For general science age up to 11 you need:
A sound sensor for noise levels.
A light sensor for day
and night
Two temperature probes for work on hot and cold
An LCD display that shows live readings |
If you have more money:
Timing switches (light gate or jump-on pressure mats)
are nice for timing jumps and measuring the speed of toy cars rolling along the floor. |
| For general science age 11
to 14
Pulse and breathing sensor
Two temperature probes for work
on insulation etc
A light sensor as a day and night marker
A sound sensor for noise levels.
Pair of light gates for timing in forces topics
|
If you have more money:
Class set of pairs of temperature probes
Class
set of pairs of light gates for forces topics
A class set of interfaces: one or two portable data loggers with displays and the rest can be basic data logging interfaces. |
| For general science age 14
to 16
Temperature probes - about three
Pair of light gates for
timing
Distance sensor for measuring speed / movement
Voltage and current sensors
Barometric (aka low) Pressure sensor
Light sensor to use as a colorimeter
A selection of individual sensors |
If you have more money:
Class set of pairs of temperature probes
Class
set of voltage or current sensors
Class set of pairs of light gates or other motion sensors for work on forces
Class set of barometric pressure sensors
|
|
| For Biology - ages 16 to 18
Temperature probes - about three
pH sensor and probe
Oxygen sensor and probe
Light sensor or a colorimeter
Pressure sensor (barometric range)
One or two physiology sensors |
|
|
| For Chemistry - ages 16 to 18
Temperature probes - about three
pH sensor and probe
Light sensor or a colorimeter
One or two other sensors according to interests |
|
|
| For Physics - ages 16 to 18
Temperature probes - about three
Pair of light gates for
timing
A selection of sensors - especially for rotary motion; distance; force;
acceleration
Voltage sensor |
