What is carbon dioxide?
What type of energy powers photosynthesis?
What is sunlight?
What gas do humans need for cellular respiration?
What is oxygen?
What is a chemical reaction?
What is a process where atoms are rearranged to form new substances?
What is the smallest part of an element?
What is an atom?
What is it called when carbon moves through plants, animals, and the air?
What is the carbon cycle?
Name one material plants need for photosynthesis.
What is carbon dioxide or water?
What do cells break down during cellular respiration?
What is sugar or glucose?
Do atoms disappear during a chemical reaction? What happens to them?
What is no, they are just rearranged?
When different atoms bond together, what do they form?
What is a compound?
When animals eat plants, what do they take in that becomes part of their bodies?
What is carbon?
What are two products of photosynthesis?
What are sugar and oxygen?
What gas is released during cellular respiration?
What is carbon dioxide?
What proves that mass is conserved in a chemical reaction/equation?
What is the total mass stays the same before and after?
What type of molecules are made of two of the same atom?
What are elemental/diatomic molecules?
Why does carbon never "run out" in nature?
What is because it is constantly cycling through ecosystems?
What happens to the sugar that plants make?
What is it is stored or used for energy?
Why do cells need to break down food molecules?
What is to release energy?
What kind of change happens when oxygen reacts with sugar in cells? (chemical or physical)
What is a chemical change?
What is the name of this element? Fe
What is Iron?
Explain how photosynthesis and respiration are connected in the carbon cycle.
What is photosynthesis removes carbon dioxide to make sugar, and respiration releases carbon dioxide by breaking down sugar?
Describe the role of sunlight in creating stored chemical energy.
What is sunlight provides energy to rearrange atoms into sugar molecules that store energy?
How is the carbon in food related to the carbon in the air?
What is carbon from food becomes carbon dioxide that is exhaled into the air?
Explain how a chemical reaction in your body follows the Law of Conservation of Mass.
What is atoms in food and oxygen are rearranged into energy and waste, but no atoms are lost?
What is the name of this element? (Au)
What is Gold?
