Which do you think will dissolve fastest? At 18 minutes we knew which one was going to be first. But we were surprised at which one was last! | This simple experiment where we had a constant variable ( red Skittle ) and a variable that changed ( liquid) began with carefully using our observation skills to look, smell, listen, touch and (yes their favorite part!) eat a skittle. We shared our observations and put them on our recording sheet. We then took the temperature of the liquids and discussed each properties. We had hot water, cold water and soda water. We made predictions and placed 1 red skittle in each and turned on the timer. |

Can the children find the buttons they carefully observed the day before from a wider range of buttons put before them? Did they take careful notes? What else would have been helpful? This lesson was about how much information we need to note, draw and include in our observations to use or share with other scientists. The children learned they needed to draw both sides of their buttons, measure them as many looked the same but were different sizes, look more carefully at the details like the ridges, bumps etc & label their pictures with what they notice.
