You have an idea for making a new type of backpack that is more comfortable to wear. The inquiry-based "5E" lesson cycle provides active, hands-on explorations of the concepts. The density of maple wood is about 755. kg/m3. What information are you given? A student measures the mass of five steel hex nuts to be 96.2 g. The hex nuts displace 13 mL of water. Whether an object floats or sinks is related to the objects density. The density of water is about Figure2.8: The density of steel, water and air one gram per cubic centimeter. 2.2 DISTANCE, TIME, AND SPEED 37 Which has more energy, the ice or the water?18. to solve it on your own. / 0.1 grams 10 assorted items such as coins, paperclips, rubber bands, 25 50 washers, marbles, popcorn kernels, etc. For instance, a solid are often expressed as g/mL, g/cm3, block of wood and a solid block of steel can have the same volume, but they would not have or kg/m3 the same mass. You can calculate density using the formula below.FOR SAMPLE ONLY - NOT FOR CLASSROOM USE m V Density gives Density gives us information about how tightly the atoms or molecules of Figure2.12: The aluminum block and information a particular material are packed. Diamond is made of carbon atoms and can have the same mass but different about atoms and has a density of 3.5 g/cm3 (3,500 kg/m3). That means the sketches are objective. b. Both the solid block of aluminum and the soda can have a mass of 10.8 grams, but the hollow can has a much larger volume. Volume of solids You have probably already learned to measure the volume of some solid shapes. What are experiments and what do they tell us? Cover up the solution to7.

The detective must have evidence that a theory describes what actually did happen. How can you variable - a quantity that cantell the rest of your team where you are? The air in your classroom has a density of about 0.001 grams per cubic centimeter (0.001 g/cm3) (Figure2.8). To read a graduated cylinder correctly, follow these two rules: 1. When is Scientific evidence must be objective and repeatable. Constraints are limits on cost, weight, time, materials, size, or other things. What is the weight, in newtons, of a 50.-kg person on the Moon?

Combine the relationships with what you know to find what you are 4 asked for. How are the atoms in water affected by forces?26 UNIT 1 THE PHYSICAL SCIENCES In this section, we will focus graph of two variables thought to on creating and interpreting scatterplots (XY graphs). You should be able to calculate any one of the three if you know the other two (Figure 2.8).Using formulas To use a formula, remember that the words or letters stand for values that the variables have (Figure 2.9). This is because the force of gravity on the Moon is six times less than the force of gravity on Earth. As a to be scientific by science.
