That night, the minimum temperature was 28C. What was the difference between the hottest part of the day and the coolest? Data challenge 2 Rainfall intensity One day in May 2015, 2000 mm of rain fell every hour for ten hours. How much rain fell in those ten hours? How many centimetres would that be? How many metres? Data challenge 3 - Irresponsible sailors that litter the sea It is estimated that one out of every ten ships discharges (throws away into the sea) 20 plastic bottles every time in comes into Hong Kong waters. There are 2000 ships coming and going from Hong Kong harbour every week. How many ships are estimated to discharge plastic bottles into Hong Kong waters? How many plastic bottles do these ships discharge in a week? How many in a year? Data challenge 4 - Sustainable fishing The Hong Kong government wants to make sure that small fish escape fishing nets. This is to increase the number of fish in the seas around Hong Kong. They can do this by making sure that the holes in the net let the small fish through but capture the larger ones. The government has decided that the size of the small fish they would like to escape is 10cm long, 5 cm high and 5cm wide. Look at the picture (not to scale) showing a fishing net with the sizes of the holes. What is the area of each of the holes in the net? Would this net allow the small fish through? If not, how would you need to change the size of the holes to let the small fish escape? If, in a few years time, the number of fish in Hong Kong waters hasnt increased, and the government decide to allow even bigger fish to escape. If they increase the size of escaping fish to 20cm long, 7.5 cm high and 7.5 cm wide, what difference will this make to the fishing nets?. Which data that you have been given has not been needed in your calculations to solve the problem?        Data challenge 5- The waste mountain grows and grows There are 2.5 million households in Hong Kong. Each household produces 10 kg of waste per week. There are also 0.5 million offices which produce 20 kg per week. Write 2.5 million as a number. How much waste will be produced in one week in total?      6cm 4cm 'L  C $     MGHIKL黲Ȼȡ֑hjhU h_hGh_5>*^Jh_OJQJ^J hJh_hJh_^JhJh_OJQJ^JjhJUmHnHuh_h_^Jh_B*^Jph h_^J h_5^Jh_CJ ^JaJ 4'L C $  V U ed$IfgdJl  & F gd_ & F gd_ & F gd_gd_+kd$$Ifl\BL F t0644 lBap(ytJd$IfgdJl d$IfgdJl F....d$IfgdJl kd$$Ifl\BL  t0644 lap(ytJ.kdj$$Ifl\BL  t0644 lap(ytJd$IfgdJl .kd$$Ifl\BL  t0644 lap(ytJd$IfgdJl     d$IfgdJl   F....d$IfgdJl kd$$Ifl\BL  t0644 lap(ytJ.)gd_kd$$Ifl\BL  t0644 lap(ytJd$IfgdJl MHJKMNPQSTVWX\]abcd$a$gdLN dgdLN & F gd_gd_LNOQRTUVX\]acd h_hGh_hLN(j2hJhJUmHnHsH tH ujhUh ,1h/ =!"#$% $$If!vh#v:V l t065/ Bp(ytJ$$If!vh#v:V l t065/ p(ytJ$$If!vh#v:V l t065/ p(ytJ$$If!vh#v:V l t065/ p(ytJ$$If!vh#v:V l t065/ p(ytJ$$If!vh#v:V l t065/ p(ytJDdtp  s >A?Picture 1"b}>1ʞßv1n}>1ʞßPNG  IHDRhL!sRGB pHYs+tEXtSoftwareMicrosoft Office5q[IDATx^,I7m۶m۶=gl۶m۶mo['^uwUݾ_Ǎ>_@Sg}g@tgVZ) ?ԧOԷoc1ҜsΙrȦrʽy4tӥgc5Xt=%X&@w^:y駟>namڳ}SNIoq/@E30i,?:*=SiϒX 馛nZB :цO>$7x?}iYfIC=t>wIM4QZlŲ6>^C 1D@/{. f#@fg@ 'v¤y7z뭗4쳧8ө'ٲ裏-1q9묳Ҵǿbѧʚ<̓&l +d0 Gy$})'T:@]6ZZjwߝ~tUWV[-_^z)38iJnz3Yg4蠃/2= a${l͖}|{l02ˤW=;Mݷߥ]6W9c+xћꁿ%*4Px:~DDX geߧX/$?L38cj7qRvꩧ6`tIբ1w$q-]:QmݖO{iJt x^z{ va9Q|"aokkx ѪN8a>³尨50?{1=а?0=ܲ99'а>ۦ3<";s믿Rz 7TFkI_~%x0E8OwetEeFZp Y 6p=rtw&F.abt7V49# j`I^x ||RKLv)3wLe :OpNJ] ̐|^Bb]tl: gFZT*@.GFz=,o"Xf#=,#  2h%74(sbT"%\-p9ỪKR%k}"xpzJ܇Y,rWR2<0'^H 2aC9$zY8M6${CDH>;~1 pLN:)Dp"WhPDd/!1 ,(8̋/#/02<:f5)6 ʖ[n}D|TNlHhf[NSM4ϡ>(LxЈw9TnEqNDsUSb~U ~!SVKս%ӠRUԌIz0Y VWCx?Ԭ,h&Ihq3P5 e"%aE(aP\R^[`aPÙGT=c*Y:m;r H^}%"SLk$2%wloѸvH˗6۬f_ywT*@V Qg5P 'J~JFLeU$b(UN+J41@ >UTԿdQ@` )0(tZHZrd, GHP4:Wg*(՘oEi6/u`0B'Hp~H؍Du}~3G$_M^eR)JkTi  9&(e}JDԠD^"5W^WD'۳ȚG;6x";dO<> dh'bZ-Z Us)gA*  &qU}d٧hql] %͈[2+º뮛5Xazsmu= Y',6sM@5n$ES0omSuIl&<54ڭ 쿚,U8B!(OZ$K֢FBdAX,'# 󨏩Dϛze @(jP_B{V_[ ̑z0=t]`TRjcXA_E[Ґu%cJ=*GR"19lӴ(9S QFo <-]zҘQ-"D>βթT0sI+8x~c/(i~4Yωdm=GtF&ʖ,HB8b>eAiZ?Ai5" ѡߎ)9;{ZUA&t J*>Ჹ{ҩ‰k(;/%<蠃6Y4'R 4g0 ^dT-}m|_9LhGᗂZ֖6 ]:$B^?4 yek3&Tgwn@NAB^>Dqp',L=o6))J]3^ {zSb{O (T'2dW5-33X5Y߉PxMA:iNqiL2Q).jh^UMH~NL٩?@T択u6/.[+jr/Qz5)6&|z׼(֦.M"u:ٕfα(]Vѡ*MDiemŒZ"" :O `I1yIU2x xϏ}aUNixρd@WAc#- :|f0/VARX6{ZÒx[ꫳvb:mջtK4h GSQ,phUWKܒc8ACa.S X?ĊFv-\Q?4+ bvѠ:iTԴA3cH+( H\fH4*=M߁HgJh ]O[hXQtM$t^"-!֗+I$`ֵh 1L.hu.&WEijT! vk 6_0A@wa#D\ w8 uf +¬@fk,i;M KDY*ULL+kP8(^⿶߭b4W8f *^ؿJj3 :^|x@PGl4ioip`\#4;"B<ퟥDBCD̓u i.|0BtI'NZ(nƗ{w$10XX,QVC$^ I8~oA|o~\1{t#XVf{ן%ۭZߋ` .JC$h!6`qM҄r%s1JX]mz,2#SǮM*ʣyr,BƠE)ZCruK/wBbS)|i /ZiD %s{{fLkru @ԲT̢dFz5qDRZI̚@4ɮh ti!8/u(byX3) oH 7i6^I"7wQ?2HPiÐf%y A@x%sA2i)%$h"~V(5ځ:b41/K':d1w_,MJO͔U{RgI,Lw.
