Terrarium Components
Terrarium Components
A terrarium is a closed ecosystem with living and non-living parts (biotic and abiotic components) working together to support each other.
Pebbles Function
Pebbles Function
Pebbles act as a drainage layer, preventing water from pooling around plant roots, which stops rot and mold growth.
Charcoal Role
Charcoal Role
Charcoal absorbs harmful chemicals in the soil, water, and air, preventing buildup and promoting a healthier environment.

Study Notes
Terrarium Objectives
- Students will work collaboratively to create a terrarium
- Students will understand terrarium components and their functions
- Students will understand the chemical reactions in a terrarium
- Students will grasp that terrariums are self-sustaining closed systems
Terrarium Components
- A terrarium is a self-sustaining ecosystem. It has both biotic and abiotic factors
- Even though it is closed, biotic factors can survive due to nutrient cycling and gas exchange
Materials List
- Dried moss, worms, plants, pebbles, soil, charcoal
- Two large glass salad bowls and water
Terrarium Design Planning
- What order should the materials be added? Explain your reasoning
- Does the size of each layer matter? Justify your answer
- What are the functions of each component?
Pebbles
- Pebbles are for drainage to prevent water accumulation around plant roots, which can lead to mold and root rot
Charcoal
- Charcoal's main benefit is toxin removal
- It absorbs chemicals from soil, water, and air that might build up overtime
- A layer of charcoal also creates drainage to prevent excess water from staying in the soil, leading to root rot and mold
Dried Sphagnum Moss
- Dried sphagnum moss increases the soil's capacity to hold water and nutrients
- It helps maintain a consistent level of soil moisture, without being overly wet
- A moss layer on top of pebbles prevents soil from mixing with the pebbles
Soil
- Soil gives structure for plant roots to grow
- It holds water for the plants
- It contains nutrients like nitrogen that plants need to be healthy
- Soil contains decomposers (bacteria and fungi) that recycle nutrients
Worms
- Worms are detritivores
- They help break down decaying matter and aerate the soil
- Springtails can combat the common terrarium problem of mold, feeding off mold and dead vegetation
- Millipedes, another beneficial organism, are scavengers that eat decaying wood, leaves, and other undesirable matter
Plants
- Plants should be slow-growing and tolerant of humid conditions.
- Inspect plants for disease before adding to the terrarium
Water
- Spritz soil and leaves with water
- Be careful not to overwater the terrarium, as excess moisture may cause mold growth
Terrarium Layers
- The order to layer a terrarium is: pebbles, charcoal, moss, soil, and plants
Terrarium Method
- Steps on how to assemble a terrarium, including quantities, and sizes for each component, such as soil, moss and pebbled.
Water Cycle
- Discuss the water cycle in the terrarium, including evaporation, transpiration, condensation, and precipitation.
Carbon Cycle
- Explain the carbon cycle within the terrarium, considering the roles of animals, plants, and carbon dioxide. Discuss processes such as feeding, respiration, and photosynthesis.
