1. Shaped like past found designs. Uses simular materials. Rock base. Near bushes.

2. We used wood and rocks to show the house.

3. Size, type, some are man made on ours and the real one wouldn't use man made products.

4. Using our materials to build a real house would cause the house to collapse with certain conditions.

5. Heat. The ground stays at a constant tempuature so you wouldn't need as much heat and cool air.

6. I think the problem solving was used to an advantage because you could save wood for a smaller fire in the colder days.

7. They would have to see what wood would hold that much weight and what design would help the wood with weight.

8. Living with the natural heat and a.c. would save energy. To make it more modern you could use modern materials such as iron and metal.

Science-The knowledge gained by observing natural events and conditions in order to discover facts and formulate laws or principles.

Technology- The application of science for pracitcal purposes.

Scientific Law- A sumary of many experimental results and observations; a law that tellshow things work.

Scientific Theory- A series of steps followed to solve problems including collecting data,formulating a hypthesis, testing the hypothesis, and stating colnclusions.

Critcal Thinking- The ability and willingness to assess claims critically

Scientific Method- a series of steps followed to solve problems including colecting data, formulating a hypothesis, testing the hypothesis, and staing conclusions.

Variable-a factor that changes in an experiment in order to test a hypothesis

Length-a measure of the straight-line distance between two points

Mass- a measure of the amount of matter in an object

Volume-a measure of the size of a body or region in three-demsensional space

Weight- a measure of the gravitional force exerted on an object

Periodic Law- The law that states that the repeating chemical and physical properties of elements change periodically with the aomic numbersof the elements.

Period- In chemestry, a horizontal row of elements in the periodic table

Group- A vertical coloumn of elements in the periodic table (also called family); elements that share the same chemical properties

Ion- An atom, radical, or molecule that has gained or lost one or more electrons and has a negative or positvie charge

Atomic Number- The number of protons in thenucleus of an atom; the atomic number is the same for all atoms of an element

Mass Number- The sum of the protons and nuetrons in the nucleus of an atom

Isotope- An atom that has the same number of protons as other atoms of the same element do but that has a different number of nuetrons

Atomic Mass Unit (amu)- A unit of mass that describes the mass of an atom or molecule; it is exactly one-twelfth of the mass of a carbon atom with mass number 12

Average Atomic Mass- the weighted average of the masses of all naturally occuring isotopes of an element

Metal- An element that is shiny and that conducts heat and elecricity well

Nonmetal- an element that conducts heat andelecricity and that does not form positive ions in an electrolytic solution

Semiconductor- an element or compound that conducts electric current better than an insulator but not as well as a conductor

Alkali Metal- one of the elements of group of the periodic tabel (lithium, sodium, potassium, rubidium, cesium, and francium)

Alkaline-Earth Metal- one of the elements of group 2 in the peri0dic tabel (beryllium, magnesium, calcium, strontium, barium, and radium

Transition Metal- one of the metals that can use the inner shell before using the outer shell to bond

Halogen- one of the elements of group 17 of the periodic table (flourine, chlorine, brmine, iodine, and astaine); halogens combine with most metals to form salts

Nobel Gas- an un reactive element of group 18 of the periodic tabel (helium, neon, argon, krypton, xenon, or radon) the has eight electrons in its outer level (execpt for helium, which has two)
