They provide a hands-on, visual way to demonstrate photosynthesis and respiration with an integrated pH indicator that changes color based on light exposure. Durable and low-maintenance, these beads support STEM and STEAM education, climate change awareness, and science fair projects with minimal setup. ## Description Algae Beads from Algae Research and Supply are a simple and easy way to perform experiments in the classroom. Our algae beads are made from Chlorella vulgaris (a green freshwater algae common across the world and commonly consumed as a nutritional supplement). We concentrate the culture and add sodium alginate in the presence of calcium ions- and POOF- algae beads are born. These simple and robust beads can be used over and over again in experiments in the classroom. Store in the refrigerator or leave on your bench top in light bright enough to read. You do not need to do anything to them for them to stay healthy for weeks. Experiments: Dark and Light: Show if photosynthesis or respiration is taking place. Light color: Place colored screens to demonstrate that the color of light is important to photosynthesis (hint: green is not that useful to algae!) Light intensity: Place containers from close to far away from a light source (hint: the containers closest to the light source will change color the fastest). You can use our color-indicator that shows if photosynthesis is taking place (change in pH). Review: Reuse over and over again! They last for MONTHS! - This was so much easier and less expensive than buying a kit from an educational supply company. In the past, I'd have to spend DAYS "awakening" the algae beads, mixing my own indicator, calibrating the indicator, etc. This kit came ready to go and use!

They last for MONTHS! *by Y***W on March 15, 2023* This was so much easier and less expensive than buying a kit from an educational supply company. In the past, I'd have to spend DAYS "awakening" the algae beads, mixing my own indicator, calibrating the indicator, etc. This kit came ready to go and use! ### ⭐ Didn't work *by A***R on February 25, 2023* Didn't work ### ⭐⭐⭐ Takes too long *by S***3 on October 13, 2021* I bought this for a class lab experiment. Unfortunately will not be able to use. It takes 24 hours for it to change pH color. Definitely not the luxury of a 55 minute class. I guess I go back to my other source of algae beads and CO2 indicators who eo work within a 30 minute time frame ## Frequently Bought Together - Algae Research and Supply: Algae Beads (Ready-to-go Algae Beads in Indicator- snap vials (x10)) - Algae Research and Supply: Algae Beads (Algae Bead pH Indicator (Concentrated 10x), 15mL) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/187498640-algae-research-and-supply-algae-beads-ready-to-go-algae](https://www.desertcart.hk/products/187498640-algae-research-and-supply-algae-beads-ready-to-go-algae) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-05-23*
