Precision describes the closeness of results that have been obtained in exactly the same way while accuracy indicates the closeness of the measurement to its true value. This experiment was used to determine the accuracy and precision of different volumetric measuring devices‚ as well as determining the density of an unknown metal. This lab was to help understand the application to volumetric measurements. Part 1: First‚ the next-to-smallest beaker was cleaned‚ dried‚ and weighed on the scale

Unit 22 1.1 Bacteria are a single cell micro-organism that can only be seen from under a microscope. It lives off the nutrients from its surroundings. Viruses are disease producing agents far smaller than bacteria‚ They are enclosed in a protein coating which makes them more difficult to destroy. The basic unit of Fungi is a hypha which is a hollow tube. The hypha threads spread out over and into the food material making a visible mesh or mycelium. Some fungi form together to create toadstools

Lab No.1: density‚ accuracy and precision Aim: to determine the relative precision and accuracy of different glassware items by calculating the density of a known substance. Introduction: the density of a substance is its mass per unit volume. (where P-density‚ m- mass and v- volume). Different materials usually have different densities and densities vary according to the pressure‚ temperature and purity of a substance. When measuring‚ there is always a small uncertainty or error and therefore

Abstract- Expirement 1: Precision‚ Accuracy‚ and Density Measurements This experience is intended to introduce the proper use of the most used laboratory equipments and glasswear that is come upon in the lab. As well‚ to determine the mass‚ volume and density of water by using various types of measuring glasswear‚ such as beakers‚ graduated cylinder‚ pipet‚ etc... The measurement of the density of water will determine the precision and accuracy of these measuring glasswear. Also‚ there will be a

Cognitive Theories Jean Piaget Jean Piaget was a cognitive theorist in 1896 – 1980. He had a way of how children learned‚ which was that they go through stages and sequences throughout their lives and they are active learners. He used firsthand experience to learn he also learned how to change what they learned into using behaviour. He did not clearly state the importance of social and emotional aspects of learning and did not focus the attention on social relationships as much as other

for people both in the sense of entire nations to individuals as well. In each instance there was a purpose for the challenges. Sometimes God was looking to see how people would act and follow laws and other times he wanted to test them. In Genesis 22 God posed a test for Abraham. He commanded him to travel to Moriah and offer his son Isaac to him as a burnt offering. Abraham obeys God and takes Isaac to the place God had told him. He brings with him two of his servants and on the way to the mountain
