How Do You Make Refrigerator Science Projects?
There are many possibilities for science project experiments, ranging in topic from mechanics to chemistry and biology. One popular biology experiment is how bacteria and fungi grow. Consider an interesting twist on this topic by adding a refrigerator to the mix. A quick and easy experiment, outlined in the steps below, can show you not only how fungi and mold grow, but how and why a refrigerator delays that growth. Using Dairy for a Refrigerator Science Project Step 1 Purchase nine petri dishes from a laboratory supplier. Most distributors sell them in packs of 20, so you will have extras to use in case of error or to use in next year’s experiment. Step 2 Choose three different types of dairy products, such as sliced or shredded cheese, milk and cottage cheese (though you don’t have to limit yourself to these three examples). Step 3 Place a sample of each dairy product you choose in three petri dishes. For example, you should have three dishes containing a small slice of cheese, three
