Observation of Digestive and Circulatory System Introduction/Background: This week’s lab is about digestion and the circulatory system. Students will be learning about the different types of digestion and circulatory systems for different types of animals. Students will learn not only about the mechanical and chemical components of digestion‚ but also the complete and incomplete digestions. The lab will also teach the open and closed‚ single and double‚ circulation patterns. Several different models

In this experiment‚ the question being asked was: “What is the water quality of the U-High stream based on the water invertebrates found?” The purpose of this experiment was to determine the water quality of the U-High creek. The data was obtained by collecting soil‚ algae‚ and water from the U-High creek and identifying the number and types of invertebrates that were found from the samples. The prediction made was that the U-High creek’s water quality was poor based on the first observations of

Observe a class in an elementary/secondary school in your area. Have a verbatim record of the teacher’s questions. Assess how well each question asked was able to move towards concept development. Analyze mistakes‚ if any‚ on the questioning process. Explain how you would have done the questioning and developed the concept as intended by the teacher. I observed a Science class in the elementary level‚ Grade 6‚ at the University of the Philippines Integrated School (UPIS). Professor REV was teaching

there are several examples of symbiosis. The relationship between the freshwater sponge and spongillafly is an example of paratism. The spongillafly lays its eggs on the sponge‚ and then they hatch and feed off the sponge. Another parasite is the flatworm. It resides in organisms such as the snail and can infect them with deadly diseases. There are also examples of commensalism in this biome. First is the relationship between small fish and the pond weeds; the fish hide between these weeds from larger

Biology Animal Phylums "Write a three sentence description for each phylum and list two examples for each. Also‚ draw a picture of a common example from each. (or cut out of a magazine). You will be graded on how accurate your information is as well as neatness." Sponges (Porifera): Poriferans don’t have mouths; instead‚ they have tiny pores in their outer walls through which water is drawn. Cells in the sponge walls filter nutrients from the water as the water is carried through the body
