2. How does the intensity of the sunlight affect pine tree height?Independent and Dependent Variables How does the amount of sugar affect the thickness of ketchup? How does the type of liquid poured on limestone affect the limestone’s texture?ID
3. Independent and Dependent Variables If you roll a heavier steel ball off an inclined ramp, then it will travel further than a light steel ball, because the heavier ball has more momentum. Independent Variable –Weight of ball Dependent Variable –Distance ball travels
4. Independent and Dependent Variables If the particles in a tube are small, then water will pass through the tube more slowly than if the particles are large, because there is less space between the particles. Independent Variable –Size of particlesDependent Variable –Speed water passes
5. A botanist conducted an experiment to see how a new fertilizer affects plant growth. He set up 100 plants and added fertilizer 3x a week. He set up another 100 plants and did not add fertilizer at all. He then measured and recorded each plant’s growth for 2 months.Independent and Dependent Variables Independent Variable –New fertilizerDependent Variable –Plant growth
6. If you increase the size of a sponge, then it will absorb more liquid, because it has more surface area. Independent and Dependent Variables How does a person’s height affect their lung capacity? How does the rate at which kool aid dissolves in water depend on the water’s temperature? ID
