Product Overview
Algae Beads is a simple and easy way to perform experiments. Our algae beads are made from Chlorella vulgaris (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.
Applications
These simple and robust beads can be used repeatedly in experiments in the classroom. Store in the refrigerator or leave on your benchtop in light bright enough to read. You do not need to do anything to them for them to stay healthy for weeks.
Module Contents
1. Introduction to Photosynthesis and Respiration.
2. Introduction to Algae and Microalgae.
3. Algae beads as a model organism.
4. What is light and how do plants use it?
5. Gas Solubility in Water. Thinking about atomic theory.
6. Introduction to pH and CO2 in water- yes they are related!
7. pH indicators and photosynthesis.
Instructions
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).
Experiments
1. Variable Light Intensity and Algal Photosynthesis.
2. Spectral Tuning and Algal Photosynthesis.
3. Temperature and Algal Photosynthesis.
4. Surface area and Volume in Algae Photosynthesis.
5. Photopigment Extraction and Analysis of Algae.
