ACTIVITY	ASSESSMENT
Teacher begins with a  friendly interaction. How  was  your  vacation? How  did  you spend? The  places you  went…? When did you get up today  morning? What did  you  eat  ? Let the  students  write  about  this.. Some of them  are allowed to  present  what  they  have  written.. Which  of  these  food items  are  obtained  from  plants? Observe the  picture  and  find  out  the  plant parts  used as  food. How  can  we  group the  plants  based on the plant parts  used as food…? Leaf Root Fruit Seed Do  we  use  stem  or  flower of  any  plant   as  food..? The  children  are  allowed to  collect  the  names of  plant parts  and  form  a table. They  present  the  list.  The  teacher  may  add suitably. Teacher  consolidates. Various plant parts  are  used for  food The  edible part  is  different  in  different  plants. Do  all the  plants  have  edible  parts? What  are  the  other  uses of  plants? Teacher  leads a short  discussion. Some of the  children respond. Teacher  asks  the  children  to  write  down  individually. They  are  allowed to  present  what  they  have  written. Teacher  records  them  on  BB. The  children  may collect data from  school medicinal garden. Teacher  consolidates  with  the  help of  picture  reading  and  discussion. The  children  are  asked to  find  out  as  many uses of  plants  .  Let  them  record in  their  science  diary. All  animals  including  man  depend   plants  for  food. ü  Don’t  the  plants  need food? ü  Where do  plants  get  food? ü  What  are  the substances  that  plants  need for  preparing  food? The children  are  asked to  read  the matter   PHOTOSYNTHESIS given in the  TB. Let  them  familiarize  the  main  ideas related to  Photosynthesis. Some  points  are  given: ü  The  process by which  plants  prepare food. ü  The  substances  needed. ü  The  importance of leaves. ü  The food  prepared by the  plants. ü  Where is  it  stored?. The  children  present  the  main  ideas  related to  Photosynthesis. Teacher consolidates.  The  consolidated  ideas  are  recorded in the  science  diary. We  have  learnt that  carbon dioxide is  necessary  for  Photosynthesis. ü  Where  is  carbon dioxide  present  around us. ü  How  do  plants  get  this  ? The  children  write  the  guess individually. Some of them  are  allowed to  say  and  explain their guess. Let’s  find out. The  information given in the  textbook  is discussed first. Then the  children  observe the  stomata  through Microscope. Peal of  Colacasia or  Beetle  leaf  is  taken  and  stained. Place  the  leaf  on  glass slide  using  a point brush Then  observed through Microscope ü  What  do you  see? ü  Don’t  you  see  small pores  ? These  are  called  stomata. The  children  draw  the  stomata  and guard cells  they  have  observed. They  are  asked to  record  the  experiment  note  on  science  diary. Teacher  shows  the  video  related  to the  functioning of stomata. We  know that  sunlight is  necessary  for  photosynthesis. Observe  the  plants  around. ü  Where  does  sunlight fall most  on  plants  ? Which  part  gets  more sunlight? Write  down  your  observation. ü  How  the  arrangement  of  leaves  helps  to  get  maximum  sunlight? The  children  observe  the  plants  and  collect  information  regarding the arrangement of  leaves. We  have  seen that  how  do plants  obtain  carbon dioxide  and  sunlight  for  photosynthesis. You  have  learnt  that  green plants  contain  chlorophyll. ü  How  do  we  identify  chlorophyll? ü  Do  all  plants  contain  chlorophyll? ü  Does  red  amaranths contain  chlorophyll? Children  write  their  guess. Designs  an experiment: Materials  needed. Procedure Recording….All steps  are  discussed  and  finalized. Designing  and  Executing of  experiment  are  done  in  groups. Presntation  in  groups. General  presentation. Observation  and  inference  are  presented. The  information  given in the  TB  is  discussed. Then  teacher  consolidates. The  children examine  the  picture  given  in  the  TB. The  following  ideas  are  consolidated. Photosynthesis  and  respiration  are  two  major  life  processes. Plants  absorb  carbon di oxide  for  photosynthesis  and  gives out  Oxygen. Plants  and  animals  take  in  Oxygen  and  give  out  Carbon dioxide  during  respiration. Thus  these  two life  processes  help  to  maintain the  balance  of  Oxygen  and  Carbon dioxide  in  atmosphere.    MODULE  :2 Duration :  3 periods Main  ideas  :  Epiphytes  ,  Parasites  ,  Saprophytes Materials  : Hand lens  ,  Decayed bread , ICT  equipments. The  children  are  allowed to  read  the  diary  note  written by  Safia. ü  Where  do  the  plants  get  water  and  other  materials  from  ? ü  How  can  they  grow  without  soil? ü  Can  you  mention  more  plants  like  these? ü  What  do  we  call them  ?  The  children  read  and  discuss the  information  about  Vanda. They  observe  its  parts Teacher  consolidates. The  children record  in the  science  diary. The  teacher  continues  the  discussion. Do  the  epiphytes  cause  any  harm to  the  host  plants? The  children  respond. Observe  the  Loranthus.  How  does  it  affect  the  host plant? Observe  loranthus  and  cuscuta  and  find  out  the  differences.. After reading  and  discussion, the  main  ideas  regarding  parasitic  plants  are  consolidated and  recorded in the  science  diary. We  have  seen that  epiphytes  absorb  water  and  materials  from  air. Parasites  depend  on the  host  plants  for  food. Let’s  see some other types.   Teacher  asks  the  children  to  observe  the  rhizopus  on  decayed  bread using hand lens. The  children observe. They  draw  the  picture . Reads  the  information  about  saprophytes. Records  in  the  science  diary.
