Line of Evidence – EngageThe temperature of a mixture can speed up or slow down the dissolving rate. Line of Evidence – ExploreThe dissolving rate of a liquid is directly related to particle size. Temperature and stirring can also have an effect. Line of Evidence – ElaborateStirring a liquid, no matter the temperature, helps a mixture dissolve. If the mixture is being stirred it will dissolve a lot faster even if the water temperature is not hot. Big Aha Thesis StatementThe dissolving rate of a mixture will increase significantly if the temperature is high, the mixture is stirred, and the particle size is small.

Evidence (Provide names and descriptions of the phases of the moon to support your claim. Describe how to tell the difference between waxing and waning phases.)After experimenting, it was concluded that the only thing that would dissolve are sugar and salt. The sand had a particle size that was too big. Stirring sped up the process of dissolving as well as heating the water. Reasoning (Explain how your evidence supports your claim. Describe how the phases of the moon repeat.)The temperature of the water influences the dissolving rate. The hotter the water, the faster it will dissolve. The particle size is important to consider too. It will take a larger particle size longer to dissolve, and it will need to be stirred into hotter water. The sugar and salt dissolved much quicker whenever the water was hot and they were stirred. They took much longer when the water was cold.

Evidence (Provide evidence from the lab to support your claim. Describe the positions of the Earth, moon, and sun that cause at least two phases of the moon.)After experimenting, it was concluded that the Kool-Aid and hot chocolate both only dissolved if they were stirred. The hot chocolate also mixed faster because it was in hot water, even though it is a bigger particle size. The Kool-Aid would fall into the bottom of the water without stirring, but the hot chocolate was too dense and floated on top without stirring. Reasoning (Explain how your evidence supports your claim. Describe how the phases of the moon repeat.)The temperature of the water influences the dissolving rate. The hotter the water, the faster it will dissolve. The particle size is important to consider too. It will take a larger particle size longer to dissolve, and it will need to be stirred into hotter water. The hot chocolate had a larger size, but when put into hot water mixed faster than the kool-aid. This proves that hot water speeds up the dissolving rate. However, when both mixtures were not stirred, the hot chocolate simply floated on top while the kool-aid sunk to the bottom. This shows that if not mixed, the dissolving rate is reduced extremely, despite the temperature of the water.

Big Ah-Ha ThesisThe purpose of this unit was to understand what effects the dissolving rates of mixtures. We completed a series of experiments to test our findings.We tested out if salt, sand, and sugar will dissolve in water. Each of them were tested in hot water, cold water, and not being stirred. This helped us see that the particle size of sand was too large to dissolve. Also, heat sped up the process of dissolving for sugar and salt. The temperature of water will heavily impact the dissolving rate of a mixture. The hotter the water, the faster it will mix. If the water is cold it will decrease the rate. Stirring will also increase the dissolving rate of a mixture as well. Each of our learning activities was a line of evidence. They helped us explain how the dissolving rate of a mixture is related to temperature, stirring, and particle size.
