I heard Oxygen and Magnesium are dating... I was like OMG

I scream! You scream! We all scream for Science and ice cream! Today is why I can not wait to teach Science. Watching Ms. F engage and excite her students was as much of a treat as the delicious ice cream we made using Science. If the instructor is passionate and knowledgeable, Science can gain interest and excitement from it's students. Ms. F displays both these qualities in her classroom. She eagerly answers the children's questions, or fixes their incorrect statements. In addition, her classroom is full of tools and equipment to guide her students learning. Today we had the pleasure of watching how to make ice cream using only a pot, spoon, milk, sugar, and liquid Nitrogen. Since liquid Nitrogen is -320 degrees F, safety comes first. Googles and gloves are a must when working with any chemical. Liquid Nitrogen is a fun tool for freezing foods and objects, but if not used properly it can be very dangerous. Never let it touch your skin! if contact occurs, it can cause serious injury. It is best to let an individual who has experience with liquid Nitrogen, use it. Liquid Nitrogen can be used to cool or freeze foods, such as the milk and sugar, quickly preserving their nutrients. this allows us to make tasty ice cream fast. The steam that fills the room as the liquid nitrogen is poured, excites the students. It causes kids to be less interested in their cell phone or doodles at the time, and more focused on Science. After the experiment is over, the children get a yummy frozen treat. But beware of brain freeze!
