Lucy has a mixture of marbles and iron she can use a sieve to separate this mixture explain why?
Lucy can use a sieve to separate the mixture of marbles and iron because the two materials have different physical properties. Marbles are typically larger and round, while iron filings are much finer and can pass through the sieve's mesh. When the mixture is poured through the sieve, the marbles will remain on top, while the iron will fall through, effectively separating the two substances. This method exploits differences in size and shape, making it an efficient way to achieve separation.
What else can I help you with?
How would you separate a bowl of marbles and iron fillings name 2 ways?
Use a magnet to attract and separate the iron fillings from the marbles, as iron is magnetic while marbles are not. Use a sieve to separate the marbles and iron fillings based on their size differences. The marbles will remain on top of the sieve while the smaller iron fillings will pass through the sieve holes.
Which tool would be best to use to separate a mixture of marbles and paper clips?
A sieve or a screen would be the best tool to separate a mixture of marbles and paper clips. The marbles, being larger and round, would not pass through the holes of the sieve, while the paper clips, being smaller and flat, would fall through. This method effectively utilizes the size difference between the two items for efficient separation.
What method would you use to separate marbles and foam balls?
One effective method to separate marbles and foam balls is by using the technique of sieving. Sieving involves passing a mixture of marbles and foam balls through a sieve with appropriately sized holes that allow only one type of object to pass through while retaining the other. By shaking the sieve, the marbles, which are larger and denser, will be retained while the lighter foam balls will pass through. This method takes advantage of the differences in size and density between the marbles and foam balls to achieve separation.
Which tool can be used to quickly separate a dry mixture containing particles of different sizes?
A sieve or a sieve shaker can be used to quickly separate a dry mixture containing particles of different sizes. The mixture is poured onto the sieve, which allows smaller particles to fall through while larger particles are retained on top.
What is frequently used to separate particles from a mechanical mixture?
A sieve or strainer is frequently used to separate particles from a mechanical mixture based on differences in particle size. This allows smaller particles to pass through while larger particles are retained, creating a separation based on particle size.
How do you separate a marble and rice mixture?
One way to separate a marble and rice mixture is to use a sieve or mesh strainer. By pouring the mixture through the sieve, the rice will pass through while the marbles will be left behind. Another method is to use your hands to physically pick out the marbles from the mixture.
How d separate flour and marbles?
To separate flour and marbles, you can use a sieve or a mesh strainer. Pour the mixture into the sieve, allowing the flour to fall through while the larger marbles remain on top. Alternatively, you could use a magnet if the marbles are metallic, or simply pick them out by hand if the quantities are small.

How do you separate polystyrene balls from marbles?
Well, isn't that a happy little question! One way you could separate polystyrene balls from marbles is by using water. Since polystyrene balls float and marbles sink, you can gently pour water over the mixture and the balls will float to the top while the marbles stay at the bottom. Just remember to do it with a gentle touch and a big smile!
What method would you use to separate marbles and foam balls?

How do you separate sawdust and marbles?
To separate sawdust from marbles, you can use a method based on their differences in size and weight. First, pour the mixture onto a flat surface or into a shallow container, then gently shake or tilt it to allow the heavier marbles to settle at the bottom. Next, you can use a sieve or screen with holes large enough to let the sawdust fall through while retaining the marbles. Alternatively, you can use water; sawdust will float while marbles will sink, allowing for easy separation.
How do you separate flour and iron?
Pour into a sieve or colander, the sand will pass through the open mesh, leaving the larger marbles trapped inside the sieve.
Which tool can be used to quickly separate a dry mixture containing particles of different sizes?
A sieve or a sieve shaker can be used to quickly separate a dry mixture containing particles of different sizes. The mixture is poured onto the sieve, which allows smaller particles to fall through while larger particles are retained on top.
How do you separate water flour and marbles?
In a beaker put in some marbles and 20ml of water.Using a filter funnel and filter paper let the water soak through the filter paper.
What tool would you use to separate the mixtures in rice from a dried soup mix?
You could use a sieve or strainer to separate the rice from the dried soup mix. Just pour the mixture into the sieve and shake it gently to separate the two components.
What science tool is used to separate gravel and water?
A sieve or a filter can be used to separate gravel and water by pouring the mixture through the sieve or filter. The gravel will stay on top while the water passes through.
