What are some other ways to physically change paper?Discussion Point
Changing from one state of matter to another is called a change of state. Changes of state are caused by changes in temperature. When liquid water is heated, it becomes water vapor- a gas. When it is cooled it turns back into a liquid. When it is put in a freezer, it becomes ice- a solid. Changes of state are physical changes because the chemical identity of the substance does not change. Changes of State
Chemical ChangesChemical change occurs when one type of substance is changed into a new substance. There are many chemical changes that take place around us every day.Burning DecayCooking Rusting
Burning is a chemical change. When a piece of paper burns, the paper and oxygen in the air combine to form ash and carbon dioxide. Anytime something burns, such as a candle or a camp fire, a chemical change is taking place. Burning
After an organism dies, the body of the organism will decay, and eventually the materials that made up the organism will be recycled back into the ecosystem. Decay is an example of a chemical change because it changes the material of an organism's body into new things. Warmer temperatures help this process happen faster. Decay
During the process of cooking, materials often change into other materials with different characteristics. When this takes place, cooking is a chemical change. Chemical changes cannot usually be reversed. For example, it is not possible to "uncook" an egg. An egg becomes stiff and white when it is cooked. Cooking
Rust is an example of a chemical change. Rust forms when iron reacts with the oxygen in the air to make a new substance with new characteristics that are different from those of the original iron and oxygen. The process of rusting is a chemical change that can affect metals, rocks, and soils that contain iron. Rusting
Signs or clues can include:Chan ge i n o dorCha nge in color Change in tasteChange in ma ssForming bubbles (giv ing off a gas)Giving off smokeGiving off lightWhat are some signs of a chemical chang e that can be observed?
Examples of Chemical Changes: Corrosion of metal—w hen i r on co m bines with oxygen in t he air, rust formsGas bubb les— Baking soda combines with vinegar, carbon dioxide forms A change in color (browning of fruit - decay) – an apple is peeled and there is a reaction with oxygen in the a ir.
Physical ChangeA physic al change is a change in the phy s i c al p roperties of matt er. The matter changed in how it looks, but what it is made out of does not chan ge.A change that takes place when a substance changes in size, shape or form. The particles of ma tter do not change.Chemical ChangesA chemical change is a c hange in the chemical properties of m atter. A chemical change occurs when two or more kinds of ma tter combine to form a new substance with different properties.A c hange that takes place when a substa nce is completely altered. The particl es of matter do change.

What is a chemical change?How i s a ch e mi cal chan ge different th an a physical change?How is heat involved in ch emical changes?How is heat invol ved in physical changes?Discussion Point
Answer: A chemi cal change produ ce s s u b stances that have ne w properties.Answer: A physical change does not produce new substances like a chemical change does. It only changes physical p roperties.Answer: Sometimes heating can cause chemic al changes. Sometim es chemical changes give o ff heat.Answer: Som etimes adding heat to matte r can change its state - when enough heat is added to it can cause melting or if heat is taken away it can cause freez ing of the matter.
