affect the structural composition of leaves. In order to identify a relationship, we compared leaf traits including mass, thickness, and area, from leaves collected at the treetop and at the bottom of the canopy. We sampled leaves from branches of four mature Acer platanoides trees. To determine the xylem tension we measured the pressure…

I had recently woken up and was still in bed. I reached over to grab my pack of Juicy Fruit and pop two pieces in my mouth. I checked my clock and it was 6:00 AM. I noticed my covers were alongside my bed. That's weird, I mean for normal people but I have a tendency for sleepwalking so I guess it’s pretty normal. “Shoot! Dammit!” I whispered as I remembered my science project was due 1st period. “Oh no no no, C’mon!” I followed up with after I opened my computer and it started to buzz and whir…
Results When we look at the results we must compare a native to a non-native to determine if the hypothesis is true. We determined earlier that we will compare American holly with Japanese privet, red bay with Florida anise tree, and kalmia with rhododendron. The American holly seemed to have more healthy leaves than the holly but not by much. The holly had 127 leaves with no damage while the privette had 139 leaves with no damage. The holly then had 97 leaves with less than ten percent damage…
Paragraph 1: Naming For the Flowering Dogwood, the Latin name is “Cornus florida”. “Cornus” derives from the word “cornu”, which today translates into a “horn”. Cornus refers to the hard wood the tree has. While “florida” stems from the Latin word “flos”, which is understood as “flower” or “flowery”. The common name for Cornus florida is Flowering Dogwood. “Flowering” comes from showy spring flowers the tree displays, while “dogwood” was most likely named after it was believed that early…
Description of plant: chamomile is an annual plant with a branched stem, 20-50 cm high. The leaves are doubly spliced split with narrow and thread-like leaves. Flower stalks is grooved and hollow at the top. Flower is conical shape and hollow inside. Flower heads carry peripheral white flowers that at night or in rainy weather or after fertilization, bow down, while the tubular flowers are yellow color.

The Similarities and Differences between Autumn and Spring There is exquisite beauty in the seasons of autumn and spring. There are also distinctions which allow each season to stand out on its own. During spring everyday something new is born from a beautiful flower to a buzzing bee. The plants and trees begin to wither in autumn as the days grow longer and cooler. Though, autumn and spring are similar seasons, they have many drastic differences such as climate, holidays, and changes…
Two Leaves, One Gone You know, I tried. I really did. As I sit here, a hole in my heart, (literally and figuratively) I wonder what I did any of this for, why this came to be. Sorry, my name’s King. I get distracted easily. I am your average but not average high schooler. Not to brag, but I’m kind of a genius. I’m a senior at 16, and had a fairly nice life. I had my loving mother, but my father had died two months ago to cancer, and it was hard carrying on. My little sister in particular, had…
Experience 3: Leaf science: how to find the hidden colours Rationale: To understand how leaves change colour and why they are green. This is aimed at moving Billy from pre-theoretical knowledge to sound scientific understanding of chlorophyll while understanding the world around him, in a visual way. Materials: Clear jars Coffee filter paper Pencils Rubbing alcohol A range of leaves, including autumn colours 10 sandwich bags Labels Gardening gloves Rolling pin Curriculum Link: NSW Science…
P. putida and P. fluorescens isolates were cultured in 250 ml Laurea Broth (LB) medium at 30±1 ºC for 36 h in an incubator shaker at 150 rpm. The culture was then poured into 50 ml falcon tubes and centrifuged for 10 min. at 6000 ×g at 4 ºC. The pellet was washed thrice in 15 ml distilled water and centrifuged. Then it was dissolved in distilled water and the optical density (O.D) of the culture was set at position-1 at 600 nm=107–108 colony forming units (CFU) ml-1 for inoculation (Bhuvaneswari…
