• Photosynthesis is the process where it will converts light energy into the chemical energy of sugars and other organic compounds

• Site where it happen is on the chlorophyll pigment.

• require carbon dioxide (CO2) and water (H2O) and store chemical energy in the form of sugar

• Oxygen (O2) is a byproduct of photosynthesis and is released into the atmosphere

• Group discussion

• Drawings with Misconceptions (POE):

These types of drawings showed some

degree of understandings on

photosynthesis and respiration concepts

but also demonstrated some

misconception but however, these

drawings were misconceptions not

understandings held by scientists or

stated in science texts.

• Drawings in this category were the most

competent and realistic drawings of the

photosynthesis and respiration in plants.

• Drawings showing sound understanding,

contained seven or more elements of the

validated response for that particular

statement

• Highlight on certain components only.

• Do not include chlorophyll pigment

• Thought that photosynthesis is the process

where gaseous exchange is occur

• Take place mainly in the leaves

• The leaves’ main job is to give off oxygen

• The leaves’ main job is to give off carbon

dioxide.

• they focus on the fact that thephotosynthesis occurs only in the leavesand they don’t say anything about thechlorophyll. It is possible to see thismisconception in the drawings

• The other misconception is theythought the Photosynthesis occurwith the rise of the rains to the skyand after evaporation, their returnto the ground
