Scooby-Doo! A Science of Chemical Reactions Mystery: The Overreacting Ghost
Scooby Doo and the gang made volcanoes in science class Here goes nothing Scoob said Shaggy Let's see what happens when we pour vinegar and baking soda into our volcano Rubbles exclaimed Scooby Like wow Shaggy said It's magic It's not magic said Daphne It's called a chemical reaction SODA BAKING VINEGAR
Everything in the universe is made of atoms or groups of atoms called molecules added Velma A chemical reaction happens when bonds between atoms or molecules are formed or broken When certain substances are put together like vinegar and baking soda they react Fred said They are called reactants They combine to form new substances called products In this reaction water and carbon dioxide are the products The carbon dioxide gas makes the volcano bubble FACT FILE When combined vinegar and baking soda react spontaneously But most chemical reactions need energy to get started activation energy Heat is one example of activation energy
Chemical reactions happen all the time Daphne said Without chemical reactions life on Earth could not exist Look at plants and trees Velma continued Photosynthesis is a kind of chemical reaction Green plants absorb sunlight explained Fred The light energy changes carbon dioxide and water inside the plant into sugar and oxygen The sugar feeds the plant and the plant releases the oxygen into the air Daphne added I wonder what chemical reactions we can use to make a hotdog asked Shaggy Rum said Scooby FACT FILE A campfire is another type of chemical reaction Fire provides the activation energy Oxygen and wood are the reactants They turn into ash and smoke which along with carbon dioxide and water vapor are the products of the reaction
Basic Photosynthesis OXYGEN LIGHT ENERGY CARBON DIOXIDE WATER A boy in class tapped Velma's arm Hey Velma Hi Brian said Velma What's up Would you like to go to the dance with me on Saturday Brian asked I'm working on my science project this weekend answered Velma The science fair is only two weeks away But thank you for asking
