For a class of 30 working in groups of 3. Brighten your photosynthesis lessons with algae beads. Students learn how to make algae beads and get hands-on experience developing and testing a hypothesis using colored filters, their algae beads, and a bicarbonate indicator solution.
For a class of 30 working in groups of 3. Looking for a way to brighten your photosynthesis lessons? Use algae beads! In this activity, students learn how to make their own algae beads and get hands-on experience developing and testing a hypothesis. They begin by learning about the correlation between light wavelength and photosynthesis. From there, student groups form hypotheses about how different colored light filters affect photosynthesis rate. Finally, they test their hypotheses using colored filters, their algae beads, and a bicarbonate indicator solution. This lab activity addresses the following Next Generation Science Standards: HS-LS1-5 and MS-LS1-6. Note: Kit includes a prepaid coupon to request perishable later at your convenience. Contact us or return the coupon to request delivery of perishable material. The algae must be grown in a lab for 2 weeks prior to use.
