Methods/Procedures To test the original hypothesis‚ six observations were taken at many different times during the day. Observations were taken during the morning‚ mid-afternoon‚ and the evening. The data was collected on four different days. To make sure that the observations would be consistent and accurate‚ two sets of observations were taken around in the same time frame. The location and the weather were constant‚ while the time of day was altered since it was the variable that was being tested

Observation Paper Alyssa Bosco St. Josephs College Running Head: OBSERVATION ASSIGNMENT ! 1 A very important young girl and boy in my life‚ had let me into their lives in order to complete this assignment‚ allowing me to understand the small and major differences between a healthy child and an autistic child. This observation assignment concerns the physical domain‚ but more specifically the development of gross motor skills. The purpose of this observation is to determine the differences in

2:8 years 3 years 6.5 years Aim & Rationale of observation: My aim while carrying out this observation was to observe a group of children‚ specifically the 2nd youngest child‚ aged 2yrs 8 months and his cognitive response to an activity involving numeracy. The type of cognitive skill I was looking for is what cognitive developmental stage children need to be at to be able to conserve and my colleague used Piaget’s Conservation Test involving Numbers to determine this.

unless it said otherwise. After each combination I looked at the reactions with a white and black piece of paper underneath the well plate to determine what was happening. Using my chart I wrote down my observations that occurred. After testing required combinations I chose 3 household cleaners to test. I chose Clorox‚ Windex‚ and dish soap and recorded their reactions. Dish soap being the most acidic out of the three. Calculation and Error: The biggest calculation and error that I can think of‚ would

Review Application and research progress of starch in polymer materials★ Wang Zhi-fen‚ Fang Lin‚ Zhang Ke-xi‚ Fu Xin Abstract: Starch a natural polymer that is characterized by cheap‚ regenerative‚ and good biodegradation is generally mixed with low density polyethylene‚ high density polyethylene‚ polypropylene‚ and polystryrene to prepare degradable materials. In order to relieve "white pollution" due to undegradability of plastic materials‚ starch is mixed with polyvinyl alcohol‚ polylactic acid
