Open the slide deck and look at slide 2. Could you keep cutting something forever? Scientists believe you would have to s_____, not because the scissors are too small, but because at some point you will come to a piece that cannot be c____ . We call this tiny piece Atoms. Matter is what takes up __________ All matter is made of ____________ All atoms have m__________. Define the following terms: Element:_____________________________________________________________________________ Molecule:____________________________________________________________________________ Compound:___________________________________________________________________________ Here is a table of some common compounds. What elements are in each compound? Circle each element. (Hint: each element is either a capital letter or a capital and lowercase letter together.) Choose 3 of these elements, and find them on the periodic table. 4 Science Watch the clip from Cloudy with a chance of Meatballs. In the movie, Flint Lockwood makes a machine that converts w__________ into f______. The movie explains it like this: Flint’s machine turns water vapour from clouds into food through a molecular phase change. The machine uses the principle of hydrogenetic mutation. Water molecules are bombarded with microwave radiation, which mutates their genetic recipe into any kind of food you want. This sounds scientific, but a lot of it is made up. Let’s see if we can correct it. Compare the Fiction with the Science In the real world, water and air are turned into food by plants using energy from the s_____ in a process called p________________. Food is mostly made up of the elements H____________, C_____________ and O__________ These are from w_________ which is H2O, and c__________ d_______________ which is CO2 It also uses some elements from the soil . Find 6 major elements and six minor elements from this website. 6 Major elements: ___________________________________________________________________ _____________________________________________________________________________________ 6 Minor elements: ___________________________________________________________________ _____________________________________________________________________________________ Which of these elements can be found in air? Could Flint’s machine make bacon and eggs in the clouds? How? Or why not? 5 Making Sugar Have a close look at the equation for making sugar: 6CO2 + 6H2O + Energy -> C6H12O6 + 6O2 Circle all the elements (hint, each element in a chemical formula is either a capital or a capital and lowercase letter next to each other.) Using a periodic table, name these elements: H =_____________________ O = _____________________ C = _____________________ Write down the molecular formula for each of the following molecules that appear in the equation above: Carbon dioxide: Water: Glucose: Oxygen: The arrow in the equation shows what products are formed when the molecules to the left of it react together. What do you notice about the number of each type of atom on the left side and right side of the arrow? From this, what can you say about the atoms in the molecules that are formed in the chemical reaction? 6 Research the following and take notes: Photosynthesis Biochemical reactions, Catabolic reactions, Anabolic reactions ATP On the next page is a diagram of how energy from the sun helps plants grow, and animals get energy from digesting food. From what you’ve learned, explain each part of the diagram. 7 8 Digestion Food can be roughly divided into three groups: carbohydrates, proteins and fats. Write down one chemical formulae for each of these. Carbohydrate Protein: Fat: What elements are present? *** Flint Lockwood makes bacon and eggs with orange juice in the clip we watched from Cloudy with a Chance of Meatballs. For each of the foods Flint mentions, find the percentage of carbohydrates, proteins and fats in them. Watch the video on the slide deck on Digestion. 9 Get Creative From what you’ve learned about molecules and how food is made, which parts of Flint’s explanation could work, and what couldn’t? Write a parody of the scene from Cloudy with a chance of Meatballs embedded in slide 6 of the slide deck. In a parody, the characters and place are the same or very similar, but you can change parts of the story, or add characters etc. Your parody must include a scientific explanation of how water can be turned into food by a machine in the air.
