Use the following recommendations to care for your carnivorous plants.

Green Thumb

A tiny seed that fits in the palm of your hand holds the blueprint for all the characteristics of a plant or very large tree. How does this process begin? What are some of the first characteristics to become visible? What do these characteristics tell us about what type of plant the seed will become? This activity will explore some of the first visible traits of a seedling and what they reveal about the plant.

Plasmolyzed Purple Onion

Demonstrate the effects of osmosis on a plant cell.

Transpiration Rate and Stomata

An activity showing that water loss is determined by leaf surface area.

Fall Foliage

Illustrate that leaves contain multiple photosynthetic pigments.

Fantastic Fluorescing Chlorophyll

Watch as chlorophyll transforms from an intense green to a bright red color as UV light is absorbed and photons are emitted from the solution.

Culturing Algae

Microorganisms often require specialized care. Learn how to properly cultivate algae and create the optimal environment with culture media, ideal temperatures, etc.

Transpiration Demonstration

How much water should be put on a plant when it is watered? Does it matter where the plant is kept? What environmental factors influence the amount of water passing through a plant?

Germination and Moisture

Seeds must have moisture if they are to sprout and grow. Is pure water required, or will any liquid do?

Seed Viability Testing

How long can seeds be stored and still be expected to grow? What percentage of seeds can be expected to sprout when planted? These are critical economic questions for gardeners and the agricultural industry.
