Explain the criteria that explanations must meet to be considered scientific (e.g., be consistent with experimental/observational evidence about nature, be open to critique and modification, use ethical reporting methods and procedures) Which of the following is a reason to express scientific findings mathematically? The findings become more difficult to prove by experiment. The findings become easier to verify by experiment. The findings become more confusing. The findings become less appealing to the public. Matter Compare the definition of matter and energy and the laws of conservation of mass and energy Which statement about matter is TRUE? are not matter but they are contained in matter. Matter exists only when you can see it. Living things are not matter. Matter is made up of Is air matter? Why or why not? Yes, because air is not alive. Yes, because air is made up of atoms. No, because air cannot be seen. No, because air does not take up space. The windows of your school are made of glass. Which of the following statements describes the motion of the molecules that make up the glass? The molecules of the are never moving. The molecules of the glass are always moving. The molecules of the glass move only when the sun warms the window. The molecules of the glass move only when the window is being opened or closed. In a cup of liquid when would the water molecules stop moving? The molecules would stop moving if the liquid water in the cup became a solid. The molecules would stop moving if the liquid water in the cup became a gas. The molecules stop moving if the liquid water in the cup became still. The molecules not stop moving in the cup of liquid water. Why can gases be compressed more easily than solids? Because the molecules of are softer than the molecules of solids Because the molecules of gases weigh less than the molecules of solids Because the molecules of gases move faster than the molecules of solids Because the molecules of gases are farther apart than the molecules of solids What happens when a cup of cold water warms up to room temperature? The size of the water molecules decreases. The number of water molecules increases. The mass of the water molecules decreases. The distance between the water molecules increases.
