In this activity related to plant biotechnology, learners use the tissue culture process to rapidly produce clones (genetic copies) of a particular plant (cauliflower, rose cuttings, African violet le

This exercise can be used to stimulate the investigative nature of learners as they use forensic plant pathology techniques to prove the learners' innocence in a mock murder investigation.

This lesson introduces learners to the world of nematodes (roundworms).

In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this activity, learners discover which plants and animals have symbiotic relationships and how this impacts each organism.

In this activity (p.25 of PDF), learners investigate spores. Mushrooms produce millions of spores which are equivalent to the seeds of plants but without the massive food reserves.

In this outdoor activity, learners search for lichen, a combination of a fungus and an alga living together. Lichen grow where most other plants cannot, on rocks, the trunks of trees, logs and sand.

This activity shows you how to make a mold terrarium using a jar and leftover food.

In this outdoor activity, learners cut through and investigate rotten logs and then make log-profile puzzles for each other.

In this family or group inquiry activity, learners use their senses to explore a local forest or woodland.

In this activity (p.7-8 of PDF), learners examine fossil formation.

In this activity related to microbes, learners make slides of cells from an onion skin and Elodea (American or Canadian waterweed) to observe under a microscope.

In this activity, learners conduct a scientific investigation involving decomposition and discover that the life cycle of trash is affected by its organic or inorganic nature.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this open-ended multicultural lab activity, learners investigate the effectiveness of herbal remedies.

In this outdoor activity, learners use a "litter-critter" wheel to help them identify different animals they find living in a natural litter habitat.

This detailed lesson plan for a field trip to Canyonlands National Park in Utah (page 32 of pdf) teaches students about the habitat of bighorn sheep.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).
