PPT-Aseel Samaro Investigating muscle strength

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 . Examining interacting muscles . There are commonly three things judges look for:. Symmetry . of the . muscles (how similar they are). Muscularity (how big they are). Level . of . conditioning (how toned they are. Understanding how seeds are dispersed by the wind . The largest seed in the world is 50 cm in . diameter.. It . comes from the palm tree called Coco de . Mer. , found only in the Seychelles islands in the Indian . 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.. Knowing how pollination leads to . fertilisation. . It is a pollen grain from a sunflower.. Pollen comes in a variety of shapes and sizes. The variety means that you might be allergic to one type but not another.. Exploring the importance of minerals to plants. All plants require essential elements that are not supplied by photosynthesis – minerals that are found in soil and absorbed by the plant through its root system.. 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. 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.. 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 . Exploring the role of stomata. Plants are found in a huge range of habitats.. In order to . photosynthesise. , plants need a supply of carbon dioxide.. How do plants get carbon dioxide? Why does oxygen, a product of photosynthesis, not build up in the leaf?. Explaining floating and sinking. The Greek physicist, mathematician and inventor Archimedes had ideas that help us to understand floating, sinking and buoyancy.. Even though he lived more than 2000 years ago his principles are still used today.. Jack M. Guralnik, M.D., Ph.D.. Department of Epidemiology and Public Health. University of Maryland School of Medicine. Domains of Functioning. Physical. Cognitive . Psychological. Sensory. Social. Disability. 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. 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.
