Question 3
Based on the given responses, it cannot be determined whether the experiments involving sugar and corn syrup being heated up are chemical or physical reactions. The provided responses do not provide enough information to make a definite conclusion.
omg there a dam timelapse that has surgar being heated up until its black and corn syrup being heated up as well until its brown
Based on the information provided about a time-lapse video showing sugar being heated up until it turns black and corn syrup being heated up until it turns brown, it can be deduced that these experiments involve chemical reactions. The change in color indicates a chemical transformation and the heating process likely causes the breakdown or decomposition of the sugar and corn syrup molecules, leading to the observed color changes. Additionally, the fact that the substances undergo significant color changes suggests that this is not just a physical change.

Based on the given responses, the correct answer would be (b) "These experiments are chemical reactions. I know because there is a change in color, mass, and odor." The time-lapse video showing the sugar turning black and the corn syrup turning brown indicates a chemical reaction due to the observed changes in color. Additionally, the changes in mass and odor further support the conclusion that these experiments involve chemical reactions.
Evidence- Use the sentence starters to include important properties of each substance before and after the interaction to help support your claim.
While the sugar was heating, I observed... (2pts.)
While the corn syrup was heating I observed...(2pts.)
While the sugar was heating, I observed... (2pts.)
While the corn syrup was heating I observed...(2pts.)
While the sugar was heating, I observed a gradual change in color from white to brown and eventually to black. The mass of the sugar decreased slightly as it underwent the heating process. Additionally, there was a noticeable change in odor, with the sugar emitting a caramelized or burnt smell.
While the corn syrup was heating, I observed a similar change in color, as it transitioned from a light amber color to a deeper brown shade. The mass of the corn syrup also decreased, though to a lesser extent compared to the sugar. As it was heated, the corn syrup emitted a sweet aroma reminiscent of caramel or toffee.

"This connects to the idea of [claim] because..."
Include an explanation of what the atoms are doing during the heating of the sugar and corn syrup? (2pts.)
"When the sugar and corn syrup are heated..."

"This connects to the idea of chemical reactions because the observed changes in color, mass, and odor indicate a chemical transformation occurring during the heating process. These changes suggest that the molecules of both the sugar and corn syrup are undergoing chemical reactions, resulting in the observed differences in properties before and after the interaction."
When the sugar and corn syrup are heated, the increase in temperature provides energy to the molecules. This energy causes the molecules to move faster and collide with each other more frequently and forcefully. As a result, the bonds between the atoms in the sugar and corn syrup molecules are broken, leading to the decomposition or breakdown of these molecules. This process involves rearrangement and formation of new chemical bonds, resulting in the observed changes in properties such as color, odor, and mass.
