| Here is a measure of which sensors and how many you might need |
| For science age up
to 7
|
|
For 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)
for timing jumps and measuring the speed of toy cars rolling along the floor. |
For 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
