|---|---|
| Disability category | visual impairment |
| Teaching units / Applicable scenes | science activities for independent living |
| Specific purposes |
• To use changes in sound to examine the strength and pathway of a light • To confirm changes in color of the light |
| Considerations for disability characteristics | Converting changes in the amount of light to changes in sound enables children with visual impairment to recognize changes in color. |
| Expected effects and results | Use of the light probe enables the children to observe changes in what they cannot see by themselves, helping to make them positive. |
| How to use |
A light sensor is installed at the tip of the light probe. When the light probe senses bright light it emits a high-pitched sound, “ping;” when it senses dim light it emits a low-pitched sound, “boo.” Children and students can perceive the light levels by listening to changes in the pitch of the sound. Example: Examine how light travels: • Examine changes in color within test tubes and the presence or absence of sedimentation. • Examine the movement of the sun (through a filter.) |
