activity‚ the skeletal system can benefit widely‚ bone density can increase from physical activity‚ this is where the skeletal tissues become stronger therefore increasing the tensile stress‚ occurring when a material is subjected to a pulling or stretching force‚ of the bone‚ this decreases the chances of osteoporosis. Also other positive effects in the skeletal system can be where cartilage thickens; this aids the cushioning of joints and protects the bones from wear. Also you can gain a greater range

objects with different amount of density and put them each in ten cups of water. I then put in teaspoons of water and recorded whether or not the objects floated until all the objects were floating. I was able to see how an objects density affects how much salt is needed to make it float. Page 2 Introduction/ Research When trying to make an object float it depends on its density. Density is the “mass per unit volume.”[7] An object floats if it has less density then water. Objects like a boat

Osteoporosis exists; they have no knowledge of what this disease is about or how to prevent it. In the article “c-Maf and you won’t see fat” Laurie McCauley defines Osteoporosis as “a metabolic bone disease that results from an imbalance between the process of bone formation and bone resorption‚ leading to reduce bone mass and increased susceptibility to fracture.” And according to Matthew Taylor‚ in his article “Osteoporosis: An Opportunity to Serve” Osteoporosis was “only officially recognized as a disease

floating and then classify objects according to whether they sink or float. CONTEXT In this activity students will determine whether various objects sink or float in water. Whether an object sinks or float in a liquid depends mainly on two factors: density and buoyancy. However‚ at this level‚ students do not need to explain why objects sink or float. They are rather to be encouraged to observe that the same objects will sink or float every time‚ i.e.‚ that there is consistency in the way the objects

The floating egg experiment – How much salt is needed to make an egg float? Aim: To investigate the effects of salt on the density of water (and therefore the ability to float an object in said water) and to find the amount of salt needed to float one regular egg in a glass of water. Research: Internet research shows that adding salt to water increases the density‚ and in turn makes it easier for objects to float. 4-10 teaspoons of salt in 1 glass of water is said to be enough to make one egg

the cell will wither and dry out—and eventually die. More generally‚ the property of water that allows it to expand when frozen only goes on to show how dependent life is on the existence of water on Earth. Because the density of frozen water‚ or ice‚ is lower than the density of liquid water‚ a layer of ice forms over the water still in its liquid state; this layer of ice insulates the water underneath it‚ ensuring that the water will remain‚ for the most part‚ in liquid form. If ice was denser

factors that might affect the growth and repair of bones. There are many different factors that can affect the growth and repair of the bones I am going to explore 4 factors and these are; * Exercise: Doing regular exercise helps build the muscle’s in the body‚ but it also helps maintain the bones and increase the bones strength. Exercise causes the muscle to contract against the bone. This action then stresses or also stimulates the bone and the bone will start to become stronger and denser. When
