From Seed to Snack

Technology(Production & Process)
From Seed2Snack


What is a flow Chart?
In a flow chart items are organized in a sequence.
Flow charts have different uses:

They may be a chain of cause and effect, explaining a process (e.g.a popcorn seed to a popcorn snack)
They may organise past events in a time sequence, recounting what happened.
They may show a series of steps, forming instructions.
They may be a sequence of reasons,in an argument.

Many flow charts are combinations of chains, forks, and loops.

Why use flow charts in the classroom?

To plan an explanation, a procedure (instructions), a recount (such as a news story), a narrative, or an argument.
To summarise an explanation, a procedure, a recount, a narrative, or an argument.
Examples of topics that suit flow charts include the water cycle, life cycles, how products are made, where a certain food comes from, preparation for a debate, how machines work, and so on. Flow charts are one of the most useful visual texts in the classroom.

We looked at 3 types of flowcharts...
Cyclic
Forked
Linear
Today we used a linear flowchart to show how the popcorn is produced, from seed to snack
