  1. F.1 Integrated Science Sink or float: Do fruits float or sink?

  2. ______________________ of fruit affects the floating or sinking of the fruits.

  3. Experiment 2： Compare floating or sinking in different objects with different volume but the same mass It is hypothesized when the objects have same mass, the objects with ____________ volume will float. • I. Making hypothesis • II. Writing procedures • a. Apparatus and materials Material: water, plasticine  Apparatus：plastic box, balances, a transparent box with calibrations

  4. Experiment 2： Compare floating or sinking in different objects with different volume but the same mass • b.Set up Placticine with same mass but different volume Water Plastic box

  5. Experiment 2： Compare floating or sinking in different objects with different volume but the same mass c. Procedures • Fill in a plastic box with 2/3 water full. • Measure the plasticine with balances and sketch the shape the plasctine. • Put the plasticine nto the plastic box and and record the floating or sinking of the plasticine. • Use the same plasticine and make it into different shape. Repeat steps 2-3. d. Variables

  6. Experiment 2： Compare floating or sinking in different objects with different volume but the same mass e. Safety measures f. Precautions • IV. Recording results

  7. Experiment 2： Compare floating or sinking in different objects with different volume but the same mass • V. Conclusion According to the experimental results, when the objects have same mass, the objects with ____________ volume will float.

  8. When the objects have same volume, the objects with ____________ mass will float. • when the objects have same mass, the objects with ____________ volume will float. • Sinking or floating of the objects relates to their density.

  9. Density • What is density? The density of a substance is the mass per unit volume. i.e. • Density = ， unit is g/cm3

  10. Experiment 1：Finding the density of an object • I. Writing procedures • (a) Apparatus and materials • (b) Set-up Material: water, a rock, plasticine  Apparatus：cylinder, balances Cylinder plasticine water

  11. Experiment 1：Finding the density of an object (c) Procedures • Fill in a plastic box with 2/3 water full. • Measure the mass of the rock with balances. • Measure the volume of the rock with a cylinder. • Record the results and calculate the density of the rock. • Repeat steps 2-4 with the plasticine to replace the rock. (d)  Safety measures (e) Precautons

  12. Experiment 1：Finding the density of an object • (f) Recording results • volume of the rock(cm3) = ___________ • mass of the rock (g) = ________________ • Density of the rock (g/cm3 ) = __________________ =_____________________ • Volume of the plasticine (cm3) = ___________ • Mass of the plasticine (g) = ________________ • Density of the plasticine (g/cm3 ) = __________________ • = ______________________
