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

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

Colorful Sugar Water Density Tower Sick Science! Summer Camp - Cooking up Kitchen science with sugar water (Submit Review) Stay inside and beat the heat or stay dry on a rainy day while testing the density of sugar water. This experiment is perfect kitchen science - it uses materials found in your pantry. We used Steve Spangler Science materials in conducting our experiment. We used four different density mixtures‚ but you can use as many as you want. * Email * * Materials

Background: This lab is all about finding the density of a candy bar‚ and determining whether or not the candy bar will float or end up sinking in a glass of water. In order to investigate the principles of mass‚ you have to find the volume and density for four different types of candy bars. My question is‚ which candy bar will have the least amount of density? Hypothesis: If a Twix has cookie inside‚ then it will have the least amount of density. Materials: 4 candy bars( Snickers‚ Twix‚ 3

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

mass at sea level is 1 kg-force. 1-6C There is no acceleration‚ thus the net force is zero in both cases. 1-7 A plastic tank is filled with water. The weight of the combined system is to be determined. Assumptions The density of water is constant throughout. Properties The density of water is given to be ρ = 1000 kg/m3. Analysis The mass of the water in the tank and the total mass are V =0.2 m 3 mtank = 3 kg mw =ρV =(1000 kg/m )(0.2 m ) = 200 kg 3 3 mtotal = mw + mtank = 200 + 3 = 203

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

71°C 3. Determine the mass of the water by using the water’s density (specific to the initial temperature) and the volume of the water. Remember‚ density =mass/volume. You can look up the density of the water at your specific temperature at http://www.ncsu.edu/chemistry/resource/H2Odensity_vp.html. (5 points) Density =mass/volume. Density of water according to NCSU: 0.9972995 g/mL Volume of water: 75.0 g/mL Find mass: Mass = Density * Volume Mass = 0.9972995 g/mL * 75.0

approximately 200 million people worldwide and approximately 14 million people in the United States. A decrease in estrogen levels in post-menopausal women puts them at a higher risk for osteoporosis and consequently leaves them at a higher risk for bone fractures. Certain types of physical activities and exercises have been shown to slow the effects of osteoporosis. Objective: The authors goal was to use previously conducted studies to determine which types of exercises and prescriptions were most
