Simple yet versatile, for a variety of investigations.

• Demonstrate photosynthesis on an overhead or document camera
• Works with aquatic or terrestrial plants
• Aligned to NGSS standards (MS/HS: PS3, LS1, LS2)

Easily demonstrate quantitative examples of photosynthesis and various environmental effects on plants with WARD’S photosynthesis apparatus. The variety of suggested experiments work with either aquatic plants or terrestrial plants. You can change the variables affecting photosynthesis and measure the rate of oxygen emitted as a byproduct, or test the influence of light intensity and wavelength, carbon dioxide and oxygen concentration in water, and other environmental factors. You can even place the apparatus on the overhead projector so the entire class can see the demonstrations. The model comes with a chamber, set of three color filters, set of three light-limiting bars, and instructions with suggested activities that can be performed with the apparatus.

The kit is also available for purchase with a link to a NewPath digital lesson, which includes a variety of resources on the topic, including background information, illustrations and self-assessments.
