    24. 24. WHAT MAKES AN OBJECT FLOAT? Question?: Does the weight of the object make things float/sink?
    25. 25. WHAT MAKES AN OBJECT FLOAT? Question?: Does the weight of the object make things float/sink? Hypothesis: I think that the density of the object will make it either float/sink
    26. 26. WHAT MAKES AN OBJECT FLOAT? Question?: Does the weight of the object make things float/sink? Hypothesis: I think that the density of the object will make it either float/sink Equipment: Rolling pin,Wooden spoon,ice-block stick,Candle (3 sizes),& water
    27. 27. WHAT MAKES AN OBJECT FLOAT? Question?: Does the weight of the object make things float/sink? Hypothesis: I think that the density of the object will make it either float/sink Equipment: Rolling pin,Wooden spoon,ice-block stick,Candle (3 sizes),& water Method: Put an object in 1 by 1, leave it for a few mins
    28. 28. WHAT MAKES AN OBJECT FLOAT? Question?: Does the weight of the object make things float/sink? Hypothesis: I think that the density of the object will make it either float/sink Equipment: Rolling pin,Wooden spoon,ice-block stick,Candle (3 sizes),& water Method: Put an object in 1 by 1, leave it for a few mins Results: Wood: All the sizes of wood floated. Candle:All the sizes of candles also floated
    29. 29. WHAT MAKES AN OBJECT FLOAT? Question?: Does the weight of the object make things float/sink? Hypothesis: I think that the density of the object will make it either float/sink Equipment: Rolling pin,Wooden spoon,ice-block stick,Candle (3 sizes),& water Method: Put an object in 1 by 1, leave it for a few mins Results: Wood: All the sizes of wood floated. Candle:All the sizes of candles also floated Conclusion:Things can float/sink, not only by the weight, but also by the material.
    30. 30. What else helps things to float?
    31. 31. What else helps things to float? Density:How tightly the atoms in the object are packed
    32. 32. What else helps things to float? Density:How tightly the atoms in the object are packed eg. If an object has low density, it will float
    33. 33. What else helps things to float? Density:How tightly the atoms in the object are packed eg. If an object has low density, it will float
    34. 34. What else helps things to float? Density:How tightly the atoms in the object are packed eg. If an object has low density, it will float Trapped Air: If you put an empty bottle in water with its lid on, it will float because of the trapped air
    35. 35. What else helps things to float? Density:How tightly the atoms in the object are packed eg. If an object has low density, it will float Trapped Air: If you put an empty bottle in water with its lid on, it will float because of the trapped air
    36. 36. What else helps things to float? Density:How tightly the atoms in the object are packed eg. If an object has low density, it will float Trapped Air: If you put an empty bottle in water with its lid on, it will float because of the trapped air Upthrust: Is a force that pushes things up
    37. 37. What else helps things to float? Density:How tightly the atoms in the object are packed eg. If an object has low density, it will float Trapped Air: If you put an empty bottle in water with its lid on, it will float because of the trapped air Upthrust: Is a force that pushes things up eg. When you push a floating object the upthrust force fights back
    38. 38. Can changing an objects shape to increase its volume make it float?
    39. 39. Can changing an objects shape to increase its volume make it float?
    40. 40. Can changing an objects shape to increase its volume make it float? Yes! because it holds air and upthrust has more space to push the object
    41. 41. Where does the water go?
    42. 42. Where does the water go?
    43. 43. Where does the water go? The size of the object displaces the water. The water rises the same amount of space the object took. This is displacement.
