F, experiment 2. T 3. F, quantitative 4. T 5. T COMPLETION 6. hypothesis 7. theory 8. Science 9. inference SHORT ANSWER 10. 1. Make observations. 2. Ask a question. 3. State a hypothesis. 4. Test the hypothesis with an experiment and collect data. 5. Draw conclusions based on the experiment. 11. She collected data that was a numerical measurement. This type of data is called quantitative data. 12. Answers will vary. Correct answers include: Chlorine makes the tap water safer. Chlorine makes the tap water taste funny. The tap water tastes better than bottled water. 13. Answers will vary. Correct answers include: There is 0.20 ppm of chlorine in her schools tap water. There is chlorine present in her schools tap water. You cant see the chlorine in tap water. 14. The statement is an inference because you are making a prediction based on your experience of the cafeteria serving pizza on Fridays. It cant be an observation because it hasnt happened yet. 15. If you record everything you did and observed in a science experiment, then others can repeat your experiment. 16. This statement is an opinion. It is Makaylas personal judgement that she loves something. An observation would be an accurate description of science class, not a personal opinion. 17. Answers will vary. Correct answers include: The desk has 4 legs The desk has a flat top. The desk has a seat attached to it. 18. If you make a mistake in your lab notebook, you should draw a line through it so it can still be read. You should not erase anything in your notebook. Sometimes a mistake can lead you to an answer or a discovery, so you dont want to erase it. 19. testable 20. Answers may vary. For a hypothesis to be correct, it must be testable. Correct answers include: The leaves are wilting because the tree does not get enough water. The leaves are wilting because the tree does not get enough nitrogen. The leaves are wilting because motor oil was spilled under the tree. ESSAY 21. No, because if your hypothesis turns out to be incorrect, that still gives you valuable information about your experiment. The information can help you to modify your hypothesis. This is all part of doing science. The main requirement for a good hypothesis is that is can be tested. *+NOPcdL M N A L l m n ɴ~j~^R~R^FR~R^FR~R^FRhF)B*CJ aJ phhF)B*CJaJphhF)B*CJaJph&hF)56>*B*CJ\]aJphhF)6B*CJ]aJphhF)B*CJaJphhF)5B*CJ\aJphhF)B*CJ$aJ$ph(h8hF)>*B*CJ OJQJaJ ph.h8hF)5>*B*CJ OJQJ\aJ ph h8h8B*OJQJ\phh8B*OJQJ\ph +OPdM N m n 5 6 A Z $ L*$7$8$H$`gdF)$*$7$8$H$^gdF)*$1$7$8$H$gdF)*$1$7$8$H$^gdF)$*$1$7$8$H$^a$gd8$ 4 5 6 @ A Y Z [ ` a b $ % & w x y klefgu Q+hB*CJaJphhF)B*CJaJphhF)5B*CJ\aJphhF)B*CJ$aJ$phhF)B*CJ aJ phhF)B*CJaJphhF)B*CJaJphhF)6B*CJ]aJphS8ye9jEIv62ˣdo?\f.h!Hezd.o |5%=27B}yʑkrY,InaKA WVE`ͣiA KB?&RX<#N^WMV$.^gen t Ȏa)3(M:X 'sZ!|ՎDRdGXh)i`g~{A&mdO^#ysOa$ɒaq3ݟPs[!!y7}Vc3,UvhFۏ1–HhOkؑ9˹0BФ֖HԑJ'F$t0ѐݜbdu12W= %n|;БdcKiH XR!o/,dQsCg-pZKqCDsE"N4MqnE'ד7K3r)GM|&;wiׅ@?~{ȅ@V~J/t#!kt('HF>/!XƼ啑Qg%hC 1ՖNB3^a# #`UF@idj^^Æ<$7z.Zaz2)k!B'@ 7QLeJjJ¾/qZQ8]r(@HOY=,m@’{wY:b>s:X&NKgӻ@F4 d$G?k`ِnȪfl9PF2 YDkfXL\XД#K2BȲ B}Fǁ9Qr ,>= H>0 L46D ӦOeLB^+nAA1 LӗjY]F~}. !\LफĄ%.&o\N8GZiD":%F5B5-Nx` 41e-m,#LY PXFbuUb<iJ I5W` QS'5R5fA%~b jiYp`6Dm!Ų!vg1ie+Oy%e+]i l;9;+,40`KX7Ŀnm'^^a$3lFMaΒL Ks2 ]ЇZJƸKze':NrW[j?-hr -pQ秖Oâr)XړA{0HZdl,Q.6SZB9{]ZrE&[-XZ[ Y~@nsBZ" -gd)*9_/al.d uk+">2\N2[28W1Z7`&`0(2&ӟ)v+-hkl',ϐ:jn[hPO-!ɞA1{:a,/ѳ0&Ma?2\3m+[f",C&ņYȩEv]d"*F `]Gp.)# ,84WPLfE|1MrȻb(jIKLBecM6KWT%-[5Dք$eAK$Ȭu geW8""ēHz[T`hXwș4@ⷝmfbE>]ai l SKI}A˕Afy&@-26i 2\͑Lt u-e ۓ8{hmYJ{ZHp!f\^DZԑ lHSq ur<EŦEjI4 E'4C /VMl3@X|&-[)we2ǀ Budn 5U`t,e'rAY6D],̯s亴e(p ,s9-rg}K@_ˎ]i:.˅D[Z# T@Fi``i]8EbSnlWbr] F^-[h,bx5E~#-"}@XY^C56%FԤ0HK/&,,c.-r)C^ҲS nҏ²ݣBIjIF.K~)ʈ }c%ݍ3jx:H*]h<ǵGH+ln?P#ONmg5#^'bfZB"$ߎ'K#:m1\?JFf.2EםI@,0\jR-za3cW"0O!lYCCUقm`77FdCKYl_u*FB/,@x{r֍rV X`Y=!r\Gvw{(?_RݥiA{Q#r*,^[<%ZQ x׺,hCcBZEH,x\%<նDx,H~8z/}p nK-`s!azaJDaё x0EYd]H! #Ձ^4Ċ=K\Ow!d͞6vd1J򍎎_ \#8߁-H{Q$Xik-1RGbb)61P4-1sYu#C+WX [2F}j[Y*YReIƅKZ*;a}ښ*CE`p# .6˨¢n1rT"- dQ˅v.Au1Ce#!xQnU ڒ#8w,] –>]\rWǫUȸ@-hVH^G#1  $,ȹD"dZeaE*}lB؋RYFUVZdm,a]Kdm.;[ y*0yͱ!φV߲dw}drq툏$S #~omd'$ KcyXEV9m`YVmd~Gm$,D>B>8 ڻIENDB`@@@ NormalCJ_HaJmH sH tH DAD Default Paragraph FontRi@R  Table Normal4 l4a (k(No ListlB7BB +OPdMNmn56AZ[ab%&xy4hlmf g   , - O P /bcl !-.<=JKfycdE~3WXQR`a O00000000000000000000000 0 0 0 0 0 0 0 000000000000000000000000000000000000000000000000000@0000000000000000000000000000000000000000000000000000000000000000000000000 VB6h(- 0dD* @ 0030000* +I$Z y ,lQ"$ $6\X6G66TCD>*urn:schemas-microsoft-com:office:smarttags PersonName V [^v{ 2 9 SVCLV_NUnuBDv*, b d 2;W_33333333333333+ Q jjkl)n= Qke q ;| .n8t$N^!?qqXrHlC-J+ YE 7"6L#$V#, )?)F)J)$*4*B*Re*+, ,P&,u/?/:1}2 3ov3f415?6l6~7LZ8[8Cs8g`9:::D;`i<Vi=8>wW?)@AfAX?C,DbEpFrFPG|}G2J8ZJ~L"M N;5NOP!R2uRSSUS[S, TKzT#6WTwW3ZD[[[\c\\]\_f_K_#U_k`b{cQ~dFf'jQ(k86n]nk1p&Gp(qEWq?rs}~sx{LxNx6y@8zMQ{:J! =K_9aT{ 3.2&Bi8>CN#k]Mtl\V M!)1/dPa ^ <ZHSQi)8M9kL<0 jG|y+F/$} `KG6'_; r_d!,Og]4_9},OU_Rg3l(`+ UWiMgQF|F:0~mF5/ ^i})" Z v#ks@ll,ZVll@@UnknownGz Times New Roman5Symbol3& z ArialCFComic Sans MS"qhF +f Jt4Jt4!242HX)?F)2#Earth Science Chapter 1 Study Guide K Osterhout K OsterhoutOh+'0 (4 T ` l x$Earth Science Chapter 1 Study Guide K OsterhoutNormal K Osterhout3Microsoft Office Word@vA@{g@fg@v7hJt՜.+,0 hp   MVUSD4' $Earth Science Chapter 1 Study Guide Title  !#$%&'()+,-./0123456789:;=>?@ABCEFGHIJKNRoot Entry F8hPData "1Table*#WordDocumentBSummaryInformation(<DocumentSummaryInformation8DCompObjq  FMicrosoft Office Word Document MSWordDocWord.Document.89q
