The Spinach Smoothie Preparation Process The process of making a spinach smoothie is quite easy‚ if one allows themselves time for preparation. There are several steps involved in making a spinach smoothie. Washing and cleaning of the vegetables‚ portioning the correct amount of ingredients‚ and proper blending are all important steps in the making of a spinach smoothie. First‚ wash all of the fruits and vegetables thoroughly‚ being careful to remove all dirt from the spinach. If carrots

La Bella Blue Cancer prevention: Blueberries Spinach Blueberries is one of the many cancer preventing foods. Blueberries are full of antioxidants and flavonoids that prevent cell damage from happening. Antioxidants is a substance‚ like Vitamin C or E that counteracts the damaging effects of oxidation in a living organism. A flavonoid is any group of organic compounds that occur as a pigments in fruits and flowers. One thing that antioxidants is neutralize free radicals‚ atoms that contain

wavelengths by reflecting the beam off of a diffraction grating‚ forming a spectrum. A mirror is used to control the angle at which the light is reflected‚ so light of a single wavelength can be passed through the sample. A pigment solution (such as spinach and acetone) is exposed to different wavelengths of light to determine the points of the highest absorbance and transmittance percentages. (Hickey‚ Mary Kay). For this experiment‚ a Bausch and Lomb Spectrophotometer was used. Often objects appear

Objectives: To use the process of chromatography to separate plant pigments. To compare the plant pigments found in spinach and red leaf lettuce leaves. Hypotheses: I believe the spinach leaf in the acetone will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. I believe the spinach leaf in distilled water will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. Discussion Questions:

◆ Bring in a can of spinach; a can opener (electric‚ if possible); small disposable bowls; and disposable spoons. Ask one student to act as the recorder again. ◆Have students name the five senses as the recorder lists them as column headings on the board. Then‚ use the can opener to open the can of spinach. ◆ Encourage students to share words that describe how it sounds. Spoon the contents of the can into bowls. Give each student a bowl containing a small serving of spinach. Ask students to describe

Cycle of Dark reaction. For this lab‚ we will test the process of photosynthesis by using Spinach leaves to observe the Hill Reaction. The Hill Reaction tests water splitting in photosynthesis‚ and can be observed when a color change occurs. This color change will occur when a molecule is split and electrons are removed from molecular oxygen and hydrogen ions. DCIP combined with sucrose or ethanol spinach mixtures‚ will give either a green color (indicating photosynthesis occurred) or no color

Chemical Separation Introduction: The objective of this experiment was to extract the pigments from spinach leaves‚ perform Thin Layer Chromatography (TLC) on the spinach leaf extract‚ and then determine the best solvent mixture to use to separate the pigments in the extract. The pigments are located inside the chloroplast walls in the cells of the spinach leaves. In order to obtain the pigments the cell walls must be broken down thus exposing the pigment containing chloroplasts. Upon
