Description
The Sun game serves as a springboard for the Guide to introduce the Child/ren to the Terrestrial Food Chain Activity. Every ecosystem, sustains its own food chain, depending upon where it is situated and which living animals or plants inhabit the area. Furthermore, there are several hierarchical levels of living organisms that share the same function in the food chain, i.e., the stronger, bigger animal eats the smaller one. When the largest consumer in the chain dies, they decompose back into the soil, as nutrients for plants. The cycle begins again.
Every ecosystem is made up of three components: producers, consumers and decomposers.
- however, the food chain could not function without an initial source of energy, the Sun
- sunlight provides the energy to generate the growth of the primary producer, the green grasslands
- the primary consumer, the grasshopper, feeds off the grass
- a secondary consumer, the frog, eats the grasshopper
- tertiary consumers, the snake, eat the frogs
- a quaternary consumer, the eagle, eats the snake
- when the eagle dies, the decomposers (bacteria), break down the body into nutrients, which return to the soil as nutrients, for the plants to grow again.
Features of the Terrestrial Food Chain Activity
- the direct objective of this material: to introduce the Child to the concept of a food chain via a visual depiction of some of the animals that fall into this category
- indirect objective: after understanding the food chain, the Child will understand the ‘cycle of life’
- the food chain is depicted as a linear or circular sequence of organisms where nutrients are transferred from one element to the other, as energy
- this activity forms part of the Montessori curriculum.
Contents of the Terrestrial Food Chain Activity
- 6 cards, illustrating, in brilliant colour, the sun as the initiator of energy, the producer and 4 consumers of the food chain
- each image has a label, naming each component
- 6 arrows, for the Child to lay out the cards in either a linear or circular pattern to indicate the direction of the food chain
- the control of error is the oblong control mat
- to enable the guide to present the work to the Child in the form of a ‘frieze’, the mat is folded in a ‘concertina’ method. This allows the guide to display one or two images at a time
- we sell the contents in a transparent plastic envelope.
Size
- mat – 71 x 17 cm / (28″ x 6.75″)I
- card – 9 x 10.5 cm / (3.5″ x 4″)
- envelope – 18 x 13 x 0.5 cm / (7″ x 4″ x 0.2″)
Activities for the Terrestrial Food Chain
- introduce the subject to the Child/ren, by presenting each image individually, in sequential order
- discuss the subject of the image, i.e., grass and which animals eat it. Allow the Child/ren to discuss their experiences and what they know, then add the label to the image
- introduce the definitions, predator, carnivore, herbivore, and omnivore with the Child/ren
- repeat with all cards, so that the images create a circle or line
- when complete, repeat the exercise, discussing this as the ‘circle of life’
- the frieze is used as a control for when the Child decides to work independently with the materials.
