Plants: Did It Sprout? Discovering Mould!


We carefully unwrapped the paper towels from last weeks experiment to see if any seeds sprouted. Just as they thought, the seeds did not sprout in the vinegar and chips but they were surprised at the results of the oil and water . . . everyone was sure that since the paper towel included water the seed would sprout . . . but no! Milk didn't sprout the seed either.

 We came to the last cup containing juice and what a surprise!! The seed didn't sprout but SOMETHING was growing . . . mould!

"What's mould?" they wanted to know. I researched their question and we learned that mould is a plant in the fungus family, it doesn't grow from seeds but from spores, which are in the air all around us, and it grows on wet food.

This discovery prompted a new experiment "Where will mould grow?" Back to the kitchen we went to find items that might allow mould to grow. They selected cream cheese, cherry tomato, slice of apple, water, soggy crackers. Everyone had an opportunity to make a prediction. Before making her guess Rielle wanted to know if the item is wet, she remembered that mould needs wet conditions to grow. All the items got a mix of of predictions, Rylan is the only one who thought that none of the items will grow mould. We shall see!!
