introduction

you ha"e di##erent $ind% o# %oil #or example peat& clay and %and' (ach type ha% it% own property)%

#or example peat i% a loo%ely type o# %oil %o it i% ea%y #or the root% to grow and peat hold% the water

#or a while %o there i% no need #or a big %er"e% o# root%' *lay on the other hand i% title pact and hart

to penetrate thu% the rood% will ta$e longer to grow and it will co%t more energy' But the clay will

hold the water #or a "ery long time thu% the root% don+t need a great %er"e%' At la%t the %and& it i% a

lo%e material %o it want hold water that well that i% a problem #or the root% there #ore they need a big%er"e% area to get enough water' ,he up%ide i% that trough to lo%e ground the root% can grow ea%ily

and don+t need lot% o# energy' -mo%t $nowledge o# my one that . learned in %econdary %chool el%e

#rom *ampbell / Ree%e& global (dition

e want to #ind out how the root% grow and witch type o# %oil i% better to grow on'

The hypothesis is

hit the in#ormation #rom abo"e the peat will grow the be%t becau%e the root% can grow ea%y and it

hold% enough water #or the plant to %ur"i"e'

Experimental procedure

Fir%t you)ll need a rihotron' ,he rhiotron i% di"ided into two chamber%& 1! cm wide and 30 cm

high each& by placing the extra %pacer upright in the middle o# the bac$ plate' ,he bac$ plate i% the

gla%% plate with three %pacer% already glued to it' ,he di"ider %pacer i% mounted with a layer o#

"a%eline to ma$e a watertight connection to the bac$ and #ront plate% o# the rhiotron'

,hen get two %un#lower $ernel% -elianthu% annuu% and rye grain% -Secale cereale witch are

%oa$ed in water #or 24 hour%' ,hen place one o# each type in either %ide' ater the %oil until it i%

dar$ened al trough' Rap the rhiotron in dar$ paper but lea# the top open #or the plant% to grow'

5a%%eur the root%& water& the growth o# the plant and the condition% o# the %oil the plant% li"e in' 6o

thi% twice a wee$ and note down how much water you added e"ery time'

Results

7ur plant% died and nothing grew& the dirt wa% dry at the and . don+t $now how much water wa%

added becau%e that data wa% lo%t' So the length o# the root and plant where 0'

discussion

,here could be di##erent rea%on% that non o# our %eed grew' 7ne i% that the %eed where dead and

couldn+t grow' ,wo there wa% not enough water added to the rihotron thu% the ground wa% to dry

#or a organi%m to li"e in' ,hird the %oil could ha"e had wrong bacteria and $illed the %eed doubt#ul

but po%%ible'

Conclusion

,he experiment went wrong %o we don+t $now how the root% grow in peat'

So my recommendation% are u%e more %eed %o you ha"e a higher chance that one o# them will grow'

ater more o#ten and chec$ i# the %oil i% wed enough multiple time% a wea$'
