Search Density of a Raisin in Google. The above screenshot appears. But do raisins float when placed in water? Does that density make sense?
Now watch this video.
Something is not adding up here. According to this video about density, objects with a density of 0.7g/mL should float. Raisins do not float. How do we resolve this dispute?
We will investigate the density of a raisin using this Google Doc and record our answers.
Our findings indicate that the density of a raisin is about 1.4 g/mL. See spreadsheet. Is Wolfram Alpha correct? Create a CLAIM about the density of a raisin and use CLAIM, EVIDENCE, and REASONING to defend it.
The image at the right shows what happens to non-buoyant raisins once carbon dioxide bubbles attach to them. What must be happening to the raisins in order for this to occur? Here is an explanation of the process.
