Fungi and protists, including mold, moss, yeast, and mushrooms, are found all around us. One common group of fungi is mold. Mold, like all fungi, are heterotrophs, which means they rely on other living things for their energy. This is different than an autotroph like a plant, which gets its energy from the sun.
Mold commonly grows on bread, getting food from this source. What do you think makes mold grow? Being in a dark place? Being exposed to moisture? Something else? The scientific method is a series of steps some scientists use to answer question and solve problems. To conduct an experiment based on the scientific method, you must have a control sample, which has nothing done to it, and several experimental samples, which have changes made to them. You can then observe results in the experimental sample to see how your changes to them affect results.

Oh dear, that must have been quite the smell! Lol
Oh wow – that’s exciting! Sounds like you learned something too! 🙂 I recall doing a similar thing with my pond water sample I was saving for weeks in the trunk of my car for a water purification class I was teaching. When I finally uncorked it, the entire school (except our class of course) was forced to evacuate because it was so strong!
So the written instructions say not to put the lid on tightly when growing the protozoa with the yeast and grass in the jar. Well, we did. Oh my goodness! Will we ever get that smell from our nasal passages???? About as stinky a smell I’ve ever smelled.
the last video looks like the movies…the scene where the organisms divide fast and the slide breaks and the video looks cool!
