UV Light Investigation Kit – Torch, UV Beads & Detection Card

UV Light Investigation Kit provides students with a practical way to investigate ultraviolet (UV) light, UV-sensitive materials and the effect of different materials on UV exposure. Designed for classroom science activities and student investigations, the kit combines a 395nm UV torch, colour-changing UV beads and a UV detection card in one convenient set.

The UV-sensitive beads change from their pale appearance to bright colours when exposed to ultraviolet light, providing an immediate visual indication of UV exposure. Students can use the beads to compare different conditions, materials and environments, while the UV detection card provides an additional tool for investigating ultraviolet light. The kit is well suited to demonstrations, group activities and science fair investigations where students can develop and test their own hypotheses.

Kit Contents

• 1 × UV torch
• 1 × Pack of 250 UV-sensitive colour-changing beads
• 1 × UV detection test card

Key Features

• Hands-on introduction to ultraviolet light
• UV-sensitive beads visibly change colour when exposed to UV light
• 395nm UV torch provides a convenient UV source for controlled investigations
• UV detection card provides an additional method for observing UV light
• 250 beads allow multiple experiments and student groups
• Suitable for classroom demonstrations and student-led investigations
• Supports comparative experiments using different materials and conditions
• Reusable components allow investigations to be repeated

Suggested Experiments

• Sunlight vs Shade: Compare the response of UV beads placed in direct sunlight and shaded locations.
• Window Investigation: Compare UV bead responses inside and outside a window to investigate how the glass affects UV exposure.
• Material Comparison: Cover groups of beads with different materials such as paper, plastic, fabric or glass and compare the results.
• UV Torch Investigation: Use the 395nm UV torch to observe how quickly the beads respond when the distance from the light source is changed.
• Distance and UV: Position beads at different distances from the UV torch and compare their colour response.
• UV Detection: Compare the response of the UV detection card under different light sources and environmental conditions.
• Colour Comparison: Investigate whether different coloured or transparent materials produce different responses in the UV-sensitive beads.
• Design a UV Barrier: Challenge students to select or construct a material combination that reduces the UV response of the beads.

Educational Benefits

• Introduces ultraviolet light and the electromagnetic spectrum
• Supports observation, prediction and experimental design
• Encourages students to identify independent, dependent and controlled variables
• Provides visible results that can be compared and recorded
• Suitable for developing science fair investigations
• Supports discussion of UV exposure and how different materials interact with UV light

Applications

• Primary and secondary science classrooms
• Light and electromagnetic spectrum investigations
• UV demonstrations
• Science fair projects
• STEM activities

Safety Information

• UV light should not be directed into the eyes or viewed directly at close range.
• Do not shine the UV torch at people or animals.
• Students should use the UV torch under appropriate adult supervision.
• UV beads are intended as an educational demonstration material and should not be used as a quantitative measure of personal UV exposure or sun protection.
