Make a UV Bead Bracelet

PA STEELS Science Standards (K–5)

Scientific & Engineering Practices (SEPs)

• SEP1 – Asking Questions & Defining Problems
  Students ask questions about UV light and make predictions about bead color changes.
• SEP3 – Planning & Carrying Out Investigations
  Students test beads in sunlight, shade, indoors, etc.
• SEP4 – Analyzing & Interpreting Data
  Students observe color changes and compare conditions.
• SEP6 – Constructing Explanations
  Students explain why beads change color when exposed to UV light.
• SEP7 – Engaging in Argument from Evidence
  Students use observations to support claims about UV exposure.

PS4: Waves & Their Applications (Light)

• PS4.A (K–5): Light travels from a source and can be detected.
• PS4.B (K–5): Objects can block, absorb, or transmit light.
• PS4.C (K–5): Some materials respond to light in observable ways (e.g., UV beads).

ESS3: Earth & Human Activity

• ESS3.C (K–5): Human actions can reduce risks from environmental hazards (e.g., UV safety, sunscreen, shade).

PA Core Math Standards (K–5)

• CC.2.4.2.A.1 – CC.2.4.5.A.2
  Represent and interpret data using charts, tables, or simple graphs.
• CC.2.3.K–5.A (Measurement)
  Use tools to measure time or conditions (e.g., “How long until beads change color?”).

PA Core ELA Standards (K–5)

• CC.1.2.K–5.A
  Identify main ideas and key details (e.g., what UV light is).
• CC.1.2.K–5.B
  Ask and answer questions about scientific topics.
• CC.1.4.K–5.S–T
  Record observations, write explanations, and use evidence.
• CC.1.5.K–5.A–D
  Participate in collaborative discussions about results.
• CC.1.5.K–5.E
  Report findings clearly.
