You will need: Colored Water, Syrup, Vegetable Oil, Large Container, Selection of objects to float.
1. Carefully pour syrup into the container until it is a quarter full. It is easier if you pour the syrup over the back of a spoon.
2. Slowly pour the same amount of vegetable oil into the container. Then add the same amount of colored water.
3. The three liquids seperate into three layers and float on each other. Now add the objects you plan to float.
4. The objects float at different levels. They sink until they reach a liquid of a higher density than themselves. They float on that liquid.
Water is more dense than the oil but less dense than the syrup.
Good job! Would the temperature of the water change the density of the water.
ReplyDeleteGreat job! Maybe you could try light karo syrup for it to see it better. Good presentation!
ReplyDeleteGood Job. This would be a good experiment to test the denisty of objects.
ReplyDeleteI wonder if the light Karo syrup would work for this experiment? Great job.
ReplyDeleteGreat way to test the density of objects! This would be fun in the classroom and to use different objects and decide which ones are most dense. You then could explain why you think that object is dense or not dense.
ReplyDeleteGreat job! Very interesting.
ReplyDeleteYou could use the light karo syrup and maybe see better. That is a really cool and easy experiment. Great job!!
ReplyDeleteGreat Job! This is a neat experiment to see different objects float at different levels. Is there any other kinds of liquids that could be used, such as honey?
ReplyDeleteGreat job! I agree that the color of the syrup affects how well you can see the objects, so a lighter color would work better. I think students would enjoy this experiment and guessing whether each object would sink or float in each liquid :)
ReplyDeleteGreat explaination! You might could try Kayro syrup....it is much lighter than the pancake syrup but might be a little thicker. I don't know if that would have anything to do with it.
ReplyDeleteGreat observation about the color of the syrup being important. I liked that you had great pictures and this would be fun in the classroom. Great job. Using different objects would be interesting.
ReplyDeleteI think this would be a great experiment to introduce density to a classroom! It would be fun and very educaitonal. It would allow the students to conversate about other objects that would float and/or sink and why.. Great job!!
ReplyDeleteGreat Job! I wonder if it would matter what temperature the water is with this experiment.I also wonder if there is a difference between the types of syrup that could be used.
ReplyDeleteIt would be fun to have students vote on whether they think an object would sink or float. Great presentation and blog post!
ReplyDeleteNice pictures. I liked how you said it would be a good experiment to use in the classroom. Did it matter which objects you trid to float?
