- 28. WHAT MAKES ANOBJECT FLOAT?
- 29. WHAT MAKES ANOBJECT FLOAT? Question?: Does the weight of the object make things float/sink?
- 30. WHAT MAKES ANOBJECT 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
- 31. WHAT MAKES ANOBJECT 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
- 32. WHAT MAKES ANOBJECT 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
- 33. WHAT MAKES ANOBJECT 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
- 34. WHAT MAKES ANOBJECT 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.
- 36. What else helpsthings to float?
- 37. What else helpsthings to float? Density:How tightly the atoms in the object are packed
- 38. What else helpsthings to float? Density:How tightly the atoms in the object are packed eg. If an object has low density, it will float
- 39. What else helpsthings to float? Density:How tightly the atoms in the object are packed eg. If an object has low density, it will float
- 40. What else helpsthings 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
- 41. What else helpsthings 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
- 42. What else helpsthings 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
- 43. What else helpsthings 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
- 45. Can changing anobjects shape to increase its volume make it float?
- 46. Can changing anobjects shape to increase its volume make it float?
- 47. Can changing anobjects shape to increase its volume make it float? Yes! because it holds air and upthrust has more space to push the object
- 49. Where does thewater go?
- 50. Where does thewater go?
- 51. Where does thewater go? The size of the object displaces the water. The water rises the same amount of space the object took. This is displacement.
