PPT-Aseel Samaro Recording experiments

Symbols and simple diagrams can accurately represent an object message or procedure without requiring the skills of an artist Introduction It is important to be able to represent how an  experiment. Exploring the movement of water and minerals in plants. Water is needed in cells to support the plant and to . photosynthesise. . Minerals in the soil dissolve in water.. How do plants get the water and minerals they need? How do they move through the plant?. Calculating pressure. Calculating pressure is important to engineers.. For example, the foundations of a building have to carry the full downwards force of its weight.. There have been cases of buildings collapsing when the pressure on the foundations was too large.. Exploring reactions of acids with carbonates . Introduction. Some rocks, such as limestone, contain a metal carbonate – limestone contains calcium carbonate. . Limestone . reacts with acids in a predictable way, and as new products are formed the limestone is eroded.. Signe Groth . Andersson. , Socialt . Udviklingscenter. SUS. , Köpenhamn; . SGA@sus.dk. . Verner Denvall, Linnéuniversitetet, Sverige; . Verner.Denvall@lnu.se. . Vad säger forskning om . performance. Exploring Magnets. Magnets have many effects, sometimes surprisingly strong.. They have many uses including computer hard drives, loudspeakers, credit card strips, magnetic fasteners and compasses for navigation.. Exploring the importance of insects . Food security refers to the availability of food and the ability to obtain it. . What is the role of bees and insects in our food security?. How does agricultural practice impact on food security?. Understanding . challenges . facing pollinators . It a scanning electron micrograph (SEM) of a pollen basket of a worker honey bee. Worker bees go from flower to flower collecting nectar and pollen to feed the colony. Analysing . adaptations . for respiration. They are both structures that transfer energy from type to another. .. Mitochondria provides energy for our . cells.. The power station provides energy for our homes. Understanding electrostatic field. Charged objects can affect their surroundings even when they are not in contact.. Sometimes people believe that they can ‘feel’ electricity in the air. The idea of an electrostatic field helps to explain this.. Explaining static charge. In ancient Greece, people started to put forward ideas about atoms.. They thought that atoms were the most basic particles and that they could not be split further.. It was not until the 1800s that ideas really developed beyond this.. Separating mixtures. If you put different objects together, such as different fruits in a bowl, toys in a box or sweets in a bag, you have a . mixture.. Simply . picking out one object separates it from the . The heart is odd one out. The heart is made from cardiac muscle. The bicep muscle (in the arm), the calf muscles ( in the legs) and the diaphragm (in the chest) are types of skeletal muscles.. Investigating muscle strength . Gemstones, such as amethyst, are crystal that formed deep in the Earth’s . crust.. Water . dissolved salts and as this solution cooled over thousands of years, the precious crystals formed.. Introduction. . Transmission Basics - Aseel AlHadlaq. Data vs Signal. Data – information formatted in human/machine readable form . examples: voice, music, image, file . Signal – electric or electromagnetic representation of data .
