SCIENCE PROCESS SKILLS Basic Science Process Skills: 1. Observing - using your senses to gather information about an object or event. It is description of what was actually perceived. This information is considered qualitative data. 2. Measuring - using standard measures or estimations to describe specific dimensions of an object or event. This information is considered quantitative data. 3. Inferring - formulating assumptions or possible explanations based upon observations. 4

Preliminary biology assignment task 3 Part A The Urey and Miller was conducted in 1952 and published in 1953 by Stanley miller‚ under the supervision of Harold Urey at the University of Chicago. It proposed the possible chance of the inorganic material of some of the basic building blocks of life‚ given that conditions resembled those of the ancient earth. This was the first ever experiment to test Alexander Oparin ’s and J. B. S. Haldane ’s hypothesis about the evolution of pre-biotic chemicals

contributions of Robert Hooke and Robert Brown. The development of the cell theory starts in the 1600ʼs with Robert Hookeʼs discovery of cells when viewing a piece of cork under a microscope and describing them as a nun house. Anton van Leeuwenhoek was crucial in the development of microscopes making simple microscopes through advanced lens making techniques that enabled him to see 300X and also discovered bacteria. Robert Brown later in the 1900ʼs made the discovery of the cell nucleus. 2 Describe

Limitations of Sight and Hearing Humans have sight and hearing limitation. Without any devices‚ our sight and hearing was limited. Most of the limitation of sight can be overcome with the help of certain optical instruments such as magnifying glass‚ microscope‚ binoculars and others. The range of frequency of hearing in human 20 Hz to 20 000 Hz. It was different according to the age of a person. Hearing limitations can be overcome by using devices such as microphone‚ stethoscope‚ earphone and PA system

Smith Lab 1: Microscopy and the Metric System Part A: Microscopy Purpose The purpose of this experiment was to learn how to use a microscope correctly and perform wet mount slides accurately‚ thus becoming more familiar with the microscope. Hypothesis It would be hard to use the microscope without any kind of previous training and the parts of the microscope and their functions must be learned in order to use it properly. Materials & Methods Materials: 1. Filter paper

when he compared the cork cells he saw through his microscope to the small rooms monks lived in. BRIEF HISTORY OF THE CELL THEORY The cell was first discovered by Robert Hooke in 1665. He examined very thin slices of cork and saw a multitude of tiny pores that he remarked looked like the walled compartments of a honeycomb. Because of this‚ Hooke called them cells‚ the name they still bear. The first man to witness a live cell under a microscope was Antonie Phillips van Leeuwenhoek‚ who in 1674 described

The samples were taken at different intervals for structural characterization by X-Ray Diffraction (XRD)‚ Field Emission Scanning Electron Microscopy (FESEM)‚ Particle Size Analysis and Dielectric Property Measurement. The X-ray diffraction patterns of the milled mixture powders‚ both calcined (1200° C) and uncalcined were recorded in X’pert Pro MPD diffractometer (PANalytical)

Language Arts Period 3-4 Ms. Truax March 28‚ 2005 Forensic Science Forensic scientists solve exiting and puzzling mysteries‚ which makes the unsolvable crimes solvable. Forensic science started in England in the 1780’s. Scientists use microscopes that can magnify things from 1‚500 to 250‚000 times! This enables them to contribute like none other to the capture of criminals. In order to become a forensic scientist‚ first you must become a scientist first. The history of forensic science
