7Student Contract 1. Attendance – Science is a subject where everyday something new is being taught. If a student is absent, a note must be presented to his/her teacher when the student returns to class. This note must have information i.e. phone number, contact person and reason for absence. 2. Lateness – Lateness will be taken very seriously and will affect a student’s grade. Students are expected to come to class on time. If you come to class late you must sign the late log and provide

Biomass Lab Design Research Question: How will the amount of soil added to the pot affect the growth of the plant? Background Information: Plants gain biomass through photosynthesis which sunlight produces energy and converts carbon dioxide along with water to carbohydrates and oxygen. Plant materials such as soil and fertilizer can also be used to produce biomass and produce biofuel from the nutrients. Hypothesis: If more soil is added to the plants pot, then more biomass will produce in the plant

Leaf Lab Report Background Cells and organisms must exchange matter with the environment to grow, reproduce, and maintain organization, and the availability of resources influences response and activities. For example, water and macronutrients are used to synthesize new molecules, and, in plants, water is essential for photosynthesis. Organisms have evolved various mechanisms for accumulating sufficient quantities of water, ions, and other nutrients and for keeping them properly balanced to

LAB 9B 1. Scroll down the CBOFS website and click on now-cast under the water level icon. The water level animation which appears displays the most recent water levels in local time at a [ (1) (2) (3) ]-hour interval. 2. Water levels are reported in the animation relative to the MLLW in feet and are color coded in the animation with the lowest water levels (indicating low tide) most likely represented by [ (green to red) (blues and purples) ]. 3. The animation shows the tides moving through

can save water, which is very useful during the winter season. Broad leaves trees, produce new leaves every spring. Photosynthesis occurs rapid in broad- leaved trees, unlike the pine leaves. d). Pines are called evergreens because the tree does not shed its leaves during the fall, they stay green all year around. e). Pine roots and fir are some plants that we’ve studied in the lab that are evergreen. f). Function: • Resin duct: secrets resin to protect pine needle plants from insects and other

LAB 1 Deforestation Eunice Reyna SCI-204 Prof. Dhalladoo October 31, 2015 This lab will discuss four points of Tropical Rain Forest. The first discussions will be on five products that come from tropical rain forest. The second one is five major causes of deforestation which I will give you some clear examples. I also will discuss the third one that cover two reasons why is so difficult especially in the Amazon tropical Forest, and finally the discussion will be on the Water and

Yeast Culture Lab Introduction Yeast is a one-celled, microscopic organism, which is part of the fungi kingdom. Yeasts do not make up a single group (Smith & Smith, 2012). Yeasts use organic material as a means of making energy, which make them chemoorganotrophs (Smith & Smith, 2012). Carbon is procured primarily from hexose sugars, such as fructose and glucose. Yeast need either oxygen for aerobic cellular respiration or for species that are anaerobic, but also
