5 Display scientific (adjective) explanation: The word scientific is used to describe things that relate to science. example: The scientist in this photo is preparing a scientific explanation so he can make information about elements, atoms, and molecules more understandable.

6 Display element (noun) explanation: An element is something in the universe, such as oxygen, mercury, or gold, that is made up of one kind of atom. example: So, when you look at the Periodic Table of Elements, you know that all atoms of a particular element are the same.

7 Display 14.9 element check for understanding You probably hear people mention ten or fifteen of the elements in everyday conversation. In addition to potassium or uranium, what elements do you hear mentioned in conversation? Begin by saying: Elements I hear mentioned in conversation include...

8 Display atom (noun) explanation: An atom is the smallest piece of a certain element that still acts like that element. example: This illustration shows a scientist s model of an atom. We can t see atoms with a regular microscope, but scientists have gained an idea of what they look like by using special microscopes.

9 Display molecule (noun) explanation: A molecule is formed when two or more atoms (alike or different) are joined together. example: This photo shows three water (H 2 O) molecules. Each one consists of two hydrogen atoms and one oxygen atom. When all the atoms in a molecule are the same, it s still the same element. When the atoms in a molecule are different, it s called a compound. So, H 2 O is a compound.

10 Display gallium (noun) The element gallium is a soft, silvery gray metal that melts easily when held in the palm of your hand.

11 Display surface (noun) explanation: The surface of something is its outer boundary. examples: Astronauts were able to walk on the surface of the moon. The swan is swimming on the surface of the lake.

12 Display process (noun) A process is a series of actions that have a particular result, such as factory workers taking raw materials and changing them into something else.

13 Display process example Many kinds of raw materials are used to create something new. For example, one kind of steelmaking process uses molten iron after it has been melted in a blast furnace. After impurities are removed and other materials are added, steel is made.

14 Display X (from Display Lesson ) process word family process verb processing verb processed adjective processing noun You could eat fresh green beans, or you could process them. Processing food means converting the food into other forms, such as steamed, canned, or frozen green beans. Food that is fresh instead of processed is healthier for you because food processing usually removes nutrients. Processed foods that are the most unhealthy are those with many added chemicals and too much sugar or salt.

15 ACTIVITY J: Content-Area Vocabulary Display List 2 1 matt er n. Matter is the physical part of the universe, consisting mainly of solids, liquids, and gases. 2 en erg y n. Energy is power that provides heat or makes machines work; it comes from such sources as the food we eat, electricity, or the sun. 3 ex plode v. When something explodes, it suddenly releases its energy. 4 carbon dioxide n. In its natural state, carbon dioxide (CO 2 ) is a colorless, odorless gas that can be turned into a liquid or a solid under certain conditions. 5 vap or n. When the temperature of a liquid substance is increasing and the liquid substance is on its way to becoming a gas, it is called a vapor (e.g., water vapor, carbon dioxide vapor). 6 alterna tive ly adv. We use the word alternatively to talk about something different from what has just been said. 7 a pproxim ate adj. If something is approximate, it is very close but not exactly the same as a certain number or a certain thing.

16 Display matter (noun) Matter is the physical part of the universe, consisting mainly of solids, liquids, and gases.

17 Display energy (noun) Energy is power that provides heat or makes machines work; it comes from such sources as the food we eat, electricity, or the sun.

18 Display energy check for understanding Energy comes from many sources. Besides the food we eat, electricity, and the sun, what are other sources of energy? Begin by saying: Other sources of energy are...

19 Display X (from Display Lesson ) 3. explode (verb) When something explodes, it suddenly releases its energy.

20 Display explode word family explode verb explodes verb explosion noun explosive adjective Most dying stars just cool off, but a few dying stars become supernovas. Supernovas are stars that explode. When a supernova explodes, it releases a great amount of energy. With its explosion, it sends almost all of its material into space. Steady light from the explosive event can be seen for about three weeks before it gradually fades away.

21 Display carbon dioxide (noun) In its natural state, carbon dioxide (CO 2 ) is a colorless, odorless gas that can be turned into a liquid or a solid under certain conditions.

22 Display carbon dioxide example Dry ice is an example of carbon dioxide in its solid form.

23 Display vapor (noun) explanation: When the temperature of a liquid substance is increasing and the liquid substance is on its way to becoming a gas, it is called a vapor (e.g., water vapor, carbon dioxide vapor). example: Water vapor rises from a hot spring in Taiwan.

24 Display alternatively (adverb) We use the word alternatively to talk about something different from what has just been said.

25 Display alternatively example You ve already said, I think I ll choose the cherry pie. If you ve changed your mind, you might say, Alternatively, the chocolate dessert looks really delicious. I think I ll choose it instead.

26 Display alternatively check for understanding You could say, For my social studies report, I think I ll write about Spain. Alternatively, writing about Argentina might be more interesting. Begin by saying: The country I would most like to visit is... Alternatively, visiting might be even more fun.

27 Display approximate (adjective) If something is approximate, it is very close but not exactly the same as a certain number or a certain thing.

28 Display approximate word family approximate adjective approximately adverb approximation noun approximating verb To have a Super Bowl party, I have to decide the approximate number of people to invite. Our backyard has room for approximately twenty people. I have to decide how much food to make. This approximation requires more math. Someone might eat more than one serving of a food item. Finally, I will be approximating the amount of soda to buy.
