Observe Environmental Impact With a Bread Mould Experiment

Bring microbiology and environmental science to life with this engaging, hands-on printable Bread Mould experiment pack! Students will explore how environmental conditions, such as moisture and temperature, affect mould growth by investigating wet sliced bread placed in different locations over five days. 

Designed for upper primary school science classes, this Bread Mould Experiment combines environmental science, scientific observation, prediction, and scientific record-keeping.

A Hands-On Mouldy Bread Experiment

This Mouldy Bread Experiment pack includes everything you and your students need to conduct a hands-on controlled investigation. Students will:

• Label four resealable bags: Sunny, Cool, Cold, and Control.
• Place one slice of bread into each bag.
• Lightly moisten each slice with the same amount of water.
• Seal each bag tightly and place it in a sunny, cool, cold, or room temperature environment to store for 5 days
• Each day, observe the bread without opening the bags.
• Record their observations, noting any mould growth, colour, or physical changes.
• On Day 5, they will complete the final observations and record their results.

Complete teacher instructions, student recording pages, and data tables are included, along with prompts for summarising findings and discussing results in groups.
