Build Water Rockets Explain how they work and ask the students which of Newton’s laws apply to them. You should talk about what forces are acting on the water rocket to make it move (talk conceptually about the idea of a free body diagram). You should have the force from the ejected propellant acting upwards‚ and the weight and air resistance acting downwards. Talk about how each law applies to the physics of the water rocket. Try to have the students identify which

impossible without water. Without water men die of dehydration About 70% of the human body is water. Of the total surface of the earth‚ 75 % is water and just below the surface of the land in most areas there is a saturated layer known as the water table. Animals and plants have large percentages of water in their make-up and some animals regulate their movements according to the water sources. If there is no water there can be no life.

Importance of Water All living things need water. The Earth is full of water. Water is the most essential element‚ next to air‚ to our survival. Water makes up more than two thirds of the weight of the human body‚ and without it‚ we would die in a few days. There are many water importances in our life to complete daily life and to maintain we body health. Humans and other creatures must drink water to avoid dehydration. Dehydration is defined as a loss or insufficient levels of water and important

The polarity of water Polarity means that the molecule has both a positively and negatively charged end. More important‚ the polarity of water is responsible for effectively dissolving other polar molecules‚ such as sugars and ionic compounds such as salt. Ionic compounds dissolve in water to form ions. This is important to remember because for most biological reactions to occur‚ the reactants must be dissolved in water. Because water is able to dissolve so many common substances‚ it is known as
