Introduction In today ’s school‚ many teachers are now well prepares with their computer skills. In college or university‚ class like Education Technology Class (ETC) at the University of Houston-Downtown is required for all students like myself who want to become future teachers. Many students get ready for teaching career will gain tremendous computer skill from this ETC class. In this paper‚ I will discuss the important role of the teacher in the classroom and why do we need more teachers

Lab 4: Photosynthesis and Chromatography of Spinach Leaves Discussion: The chromatography of the spinach leaves was taken to establish what pigments were present in the chloroplasts of the leaves. The solvent carried and separated the different pigments up the cellulose paper. The solvent moved up the paper because of capillary action because of adhesion of the solvent molecules and the paper. The pigments dissolved in the solvent also were carried up the paper and were separated because

Introduction: Trying to find a good‚ quantitative procedure that students can use for exploring photosynthesis is a challenge. The standard procedures such as counting oxygen bubbles generated by an elodea stem tend to not be “student” proof or reliable. This is a particular problem if your laboratory instruction emphasizes student-generated questions. Over the years‚ I have found the floating leaf disk assay technique to be reliable and understandable to students. Once the students are familiar

Photosynthesis Investigation Research Question How does length of pondweed affect the amount of bubbles produced in 2 minutes by pondweed during the process of photosynthesis? Independent variable: Length of pondweed (8/10/12 cm). Dependent variables: amount of bubbles produced in 2 minutes. Control variables: Volume of water in the beaker (500ml)‚ The volume of water has to be the same every time‚ so when doing the experiment I need to make sure I always use these 500 ml that i have already

Chivalry is Still Needed Today Chivalry was established to keep Medieval Knights in check. Knights in the Middle Ages were heavily armed and prone to violence. In the 21st century‚ the word chivalry evoked a kind of old-fashioned male respect for women and during the Middle Ages‚ the code was established for much grittier reasons. Imagine a world where no one shows any respect to others‚ no one holds the door for people‚ no one listens to their elders‚ and everyone is involved in violence.is that

Photosynthesis and Cellular Respiration lab makeup Photosynthesis absorbs energy from the the sunlight ‚and water‚and carbon dioxide to to create energy sugar ‚and oxygen. Photosynthesis also absorbs molecules that are called pigments. The process of photosynthesis is used by plants to make food for themselves. By then doing this‚ it also benefits us humans and animals by releasing carbon dioxide. Oxygen to them is considered a waste product‚ but a necessity to us. The photosynthesis
