The chocolate was burnt. The chocolate turned black and crispy.

This is no reversible because how are you going to reverse the bubbles.💧💧

It can be reversed if you put more wax in it]]> 2018-03-02 00:58:36 UTC https://padlet.com/56Waugh/jt1s11xu7peh/wish/237243971 https://padlet.com/56Waugh/jt1s11xu7peh/wish/237244234 Bellas melted chocolate experiment 🍫 the chocolate melted because of the air temperature. The air temperature is too warm for the chocolate to be kept out for too long🔥. This chocolate can be reversed because you can seal up the chocolate and put it in the fridge❄️.

The powder mixed together and reacted by bubbling and forming a sort of gooey substance and after a while it desolved and we do not think that it can be reversed because the powders has desloved or turned into goo and cannot go back into powder]]> 2018-03-02 01:01:48 UTC https://padlet.com/56Waugh/jt1s11xu7peh/wish/237244497 https://padlet.com/56Waugh/jt1s11xu7peh/wish/237244560 When the tablets entered the water they started to bubble and dissolve.
We don't think this is reversible because the second time he tablet entered the water it started to dissolve. 💦💦💦]]> 2018-03-02 01:02:17 UTC https://padlet.com/56Waugh/jt1s11xu7peh/wish/237244560 https://padlet.com/56Waugh/jt1s11xu7peh/wish/237244646 A green sticky liquid that was once a icy pole and has been left out to melt it is spreading I reckon if this got put back into the freezer it would turn back into ice. ]]> 2018-03-02 01:02:43 UTC https://padlet.com/56Waugh/jt1s11xu7peh/wish/237244646 https://padlet.com/56Waugh/jt1s11xu7peh/wish/237245291 the tablet sunk to the bottom of the cup and when it was half dissolved it went to the top of the cup.

It smells like almonds and looks like chunky milk. ( unless it’s melted like it’s starting to now ) it can be revearsed because you can put the lid on and put the carton in the fridge❄️🥛🥜

The original one is still whole and it doesn’t have any wax that is melted 
The second one which is on fire has half melted and the last one is completely melted the change is not really reversible because it has already melted so it cannot be reversed back into its own shape but it can still be set again just not in its original shape.]]> 2018-03-02 01:15:55 UTC https://padlet.com/56Waugh/jt1s11xu7peh/wish/237247289 https://padlet.com/56Waugh/jt1s11xu7peh/wish/237247635 2018-03-02 01:17:33 UTC https://padlet.com/56Waugh/jt1s11xu7peh/wish/237247635 56Waugh https://padlet.com/56Waugh/jt1s11xu7peh/wish/237251078 There were different science experiments set up. Each experiment contained different materials or substances. We observed the change in the materials or substances. We described the changes by comparing what the material looked like before and after.  Lastly, we decided whether the change was reversible or irreversible. ]]> 2018-03-02 01:37:28 UTC https://padlet.com/56Waugh/jt1s11xu7peh/wish/237251078
