What is the variable in bread mold experiment?

What is the variable in bread mold experiment?

In an experiment with moldy bread, a researcher might be trying to determine how much moisture it will take for a bread to go moldy. The independent variable would be how much water the researcher sprays on the bread. The amount of water is the independent variable because this is the variable the researcher controls.

Which bread molds the fastest hypothesis?

Organic white bread usually molds faster than non-organic white bread because it contains fewer preservatives.

What is the conclusion of bread mould?

A Conclusion. Mold is a fungus that best grows in dark, moist and warm conditions. It feeds on organic matter like bread while decomposing the same. Hence it is harmful to consume the moldy bread or even inhale the smell as mold spores could enter the body in that way.

What factors affect mold growth on bread?

The most important factors influencing mould growth are moisture, temperature, type of substrate and exposure time, whereas less important factors are, e.g. availability of mould spores, pH, light, oxygen and surface roughness (Vereecken and Roels, 2012).

How does temperature affect bread mould?

Bread moulds need a food source to grow and survive. Optimal mould growth occurs in warm temperatures, since enzymes, or the proteins that control chemical processes, work more efficiently when it is warm rather than when it is cold.

What happens if you eat off bread?

The Bottom Line. You shouldn’t eat mold on bread or from a loaf with visible spots. The mold roots can quickly spread through bread, though you can’t see them. Eating moldy bread could make you sick, and inhaling spores may trigger breathing problems if you have a mold allergy.

Can you eat moldy bread?

Is it OK to eat bread with just a little mold on it? The USDA says you should refrain from eating bread with even the smallest traces of mold, because even if it isn’t visible, microscopic roots can intertwine their way throughout the food. If you find mold at all, they advise discarding the entire loaf.

How do you do a mold experiment on bread?

How to Do Mold Bread Experiment 1 Hypothesis. A piece of bread kept under moisture and high temperature develops mold on its surface. 2 Materials Needed 3 Procedure. Sprinkle water on the slice of bread. Put the bread in the plastic bag and zip it. Use the tape to secure it further.

How does water affect the growth of bread mold?

The purpose of this lab was to test the effect of water on bread mold growth. Hypothesis: hypothesized bread mold would grow faster if the bread was exposed to water. Materials: 1. Bread 2. Plastic cup 3. Water 4. Rubber band 5. Plastic wrap 6.

What kind of bread grows mold the fastest?

“Mold grows quicker at higher temperatures.” ( Hypothesis) 15 slices of bread. Any sort will do but it is perfectly fine to use cheap white sliced bread as then you will know that all of the slices are a similar size, weight and thickness.

What is an example of a biology experiment with molds?

This biology experiment requires you to gather some background information before starting with the research. Once you know what the organisms called molds are, understanding the activity would be easy. A piece of bread kept under moisture and high temperature develops mold on its surface. Sprinkle water on the slice of bread.
