Buckskin for outside , sticks for the frame and rocks.and mores sticks for the ladder.<br /><br />3.How are these materials different than the ones used for the full sized house? <br />they are different from a actual pithouse is that different materials are used for the model to the actual.<br /><br />4. What would happen to your construction if you used the materials from the model? it probly would not hold up like the original materials.<br /><br />5. what type of problem does the pit house solve? it gave shelter and temperture.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1470501979737631623-1556982461985274499?l=billyscience.blogspot.com' alt='' /></div>science studenthttp://www.blogger.com/profile/03940298033626017457noreply@blogger.com0tag:blogger.com,1999:blog-1470501979737631623.post-11875622414708974962008-09-29T09:36:00.000-07:002008-09-29T10:01:46.696-07:00<span style="color:#ffcc33;">periodic law</span>- the law that states that the repeting chemical and physical properties of elements change periodically with the atomic numbers of the elements.<br /><br /><span style="color:#33cc00;">period</span>- a horizontal row of elements in the periodic table.<br /><br /><span style="color:#3333ff;">group</span>- a vertical column of elements in the periodic table.<br /><br /><span style="color:#663366;">ion</span>- an atom or group of atoms that has lost or gained one or more electrons and has a negative or positive charge.<br /><br /><span style="color:#000066;">atomic number</span>- the number of protons in the nucleus of a atom.<br /><br /><span style="color:#996633;">mass number</span>- the sum of the numbers of protons and neutrons in the nucleus of a atom.<br /><br /><span style="color:#993300;">isotopes</span>- an atom that has the samenumber of protons as other atoms of the same element do but that has a different number of neutrons.<br /><br /><span style="color:#ff99ff;">atomic mass unit</span>- 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.<br /><br /><span style="color:#ffff66;">average atomic mass</span>- the weight averge of the masses of all naturally occurring isotopes of an element.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1470501979737631623-1187562241470897496?l=billyscience.blogspot.com' alt='' /></div>science studenthttp://www.blogger.com/profile/03940298033626017457noreply@blogger.com0
