Botany 2 - Photosynthesis and Transpiration

The girls wrapped up their botany this week by looking at photosynthesis and transpiration.

We used our button leaf to recap photosynthesis and discussed how it all works.

The younger two made a poster, 

not sure how clearly it shows on the photo but they decided to stick some sugar to the leaf 'cause leaves are where the food is made' was their reasoning.

We discussed transpiration and dissected some stems to look for the xylem tubes. Rose decided they were the plants straws and stuck one on her poster to show the plant sucking up the water (blue ribbon)

and they decided to jazz up the transpiration experiment by using two different coloured liquids to see how that would effect the petal colour (some think we'll end up with purple and some think half blue and half red)

I'll let you know the outcome next week.

I've decided to leave leaf shapes until there are actual leaves on the trees : )
