Lots of points science fair conclusion idk how to word it better. my hypothesis : if you replace oil with applesauce in a cake, then the baking time be extended. my problem: does replacing oil with applesauce affect the baking time in a cake? my conclusion (what i need with wording better): in conclusion, this experiment showed that on average the cake that had oil replaced with applesauce took longer to bake when the oil was replaced with applesauce. this does support our hypothesis that if you replace oil with applesauce in a cake, then the baking time be extended. while performing this experiment we found that on average the applesauce cake took longer to cook than the regular cake by only 2 minutes. if someone has an allergy to oil then they can still eat cake because applesauce makes an amazing substitute for oil.
