Two large glass jars or clear plastic bottles
Natural gravel or stones from a nearby location
Soil from the ground
Native plants, such as small ferns, mosses, or grasses
Water from a local stream, pond, or collected rainwater
Natural decomposers like worms or small insects found in the area
Collect a layer of gravel or stones and place it at the bottom of the first jar for drainage.
Scoop soil from the ground and add it on top of the gravel.
Harvest some native plants and plant them into the soil.
Add water to the jar, ensuring the soil is moist but not flooded.
Gently introduce decomposers and small insects into the jar.
Seal the jar and place it in a spot that receives natural but indirect sunlight.
Encourage students to observe the ecosystem daily.
Discuss the natural cycles they see, such as the water cycle and life cycles of the plants and animals.
Same as the healthy ecosystem jar, but include elements that would naturally disrupt the balance, such as excess organic matter or an imbalance in species.
Follow the same steps as the healthy ecosystem jar, but introduce factors that would naturally create an unhealthy ecosystem, such as not including plants, or using a non-native plant
Have students observe and note the differences between the two ecosystems over time.
The impact of environmental changes on an ecosystem’s health.
The role of biodiversity in maintaining ecological balance.
The effects of human activities on natural ecosystems.
This activity will help students appreciate the complexity of ecosystems and the
importance of each component within them. It’s a great way to bring the outdoors into the classroom and foster a hands-on understanding of environmental science. Enjoy your ecological exploration!
