Then remove the wrappers of two hard candies, and place them in the second glass. What do you think will happen to the candy if left untouched for 30 minutes?

Why do you think this will happen, and will the water change? While you are waiting fill the two additional glasses with one third cup of hot water. Be careful not to get any hot water on your hands.

Carefully place two gummy bears in the first glass. Then remove the wrappers of two hard candies and place them in the second glass. What do you think will happen to this candy if left untouched for 30 minutes?

Do you expect it to be different from the candy in the cold water? Why would this be the case? Do you expect the water to change?

For each of these cold water glasses, take a clean spoon to stir the water, scoop up a sample and taste it. Which one is sweetest? Take a fresh gummy bear and a hard candy out of the bag removing the wrapper if neededand place the candy next to the candies that have been soaked for 30 minutes.

What differences do you observe?

Is what you observe consistent with what you expected? If it is different, why do you think this is the case? Looking at the change in the size of the candies and the taste of the water, what do you think happened to each type of candy when submerged in water?

After the second timer goes off and the Hot Water row candies have been submerged for 30 minutes, repeat the observation procedure for these candies.

Now that we have seen what cold and hot water does to these types of candy, let us look closer at the influence of temperature. How is the candy soaked in hot water different from the same type of candy soaked in cold water? Why do you think this has occurred? Pop a fresh candy from the bag into your mouth.

Notice how your mouth is a watery environment that is at body temperature. How do you think your previous observations relate to the feel and taste of the candies in your mouth?

Use a ruler to measure the lengths of the unsoaked and soaked candies, then express the change as a percentage. Can you estimate the change in volume as well? You can also compare the sizes of the candies soaked in hot water with those soaked in cold water. Study the influence of heat further by filling a glass with one third cup of ice-cold water and another glass with one third cup of hot water.

If possible, place the hot water glass in a hot water bath, so the water does not cool off as fast. Put a brightly colored hard candy in each glass and watch how the color spreads in each glass.

They drive the submarine into this vast ice cave and find that the seawater is warmer than expected and there is evidence of melt. Nov 08,  · Does adding salt to ice and water slow down, speed up, or not change the rate the ice melts in the water?

Is salt the only substance to have this effect? What about sugar? Knowing how to speed up the melting rate of ice is very important information for anyone who needs to de-ice roads or driveways 4/5(). 1 – 2 Meters Of Sea Level Rise By A ‘Highly Erroneous’ Claim Geophysicist and tectonics expert Dr.

Aftab Khan has unearthed a massive fault in the current understanding of (1) rapid sea level rise and its fundamental relation to (2) global-scale warming/polar ice melt. Succinctly, Dr.

Khan concludes the two have little to nothing to do with one another.
