. **Keeping Ice Frozen**

 ** Problem **: What material, bubble wrap or tin foil, will keep ice frozen the longest?
 * Research bubble wrap is an insulator tion foil is an condutor (Define insulator and conductor.) **


 * Hypothesis: if you put ice in bubble wrap then it will stay a soild longer (than in tin foil). **


 * Materials**: 2 ice cubes, bubble wrap ,t in foil, timer


 * Procedure:**

1.) Using a scale weigh the ice cube. 2.) Wrap an ice cube in tin foil and set on tray. 3.) Wrap another ice cube in bubble wrap and set on tray. 4.)  Wait 30 minutes. 5.) After 30 minutes, unwrap each package. 6.) Weigh the ice cube again. 7.) Write the observations in the chart.


 * Results:**
 * = Material = || = Observations = ||

= Tin Foil = || 14g to 3g this ice melted faster do to the tin foil alwoing many heat waves ||

= Bubble Wrap = || 12g to 7g this ice melted slower do to buble wrap being an insulator ||


 * Conclusion: my hypothsis was right. my hypothsis was if you put an ice cube buble wrap it won't melt as fast as in tin foil. this is do to the fact that tin fiol is a condutor so heat wavs pass through eslay, bubble wrap is an insulator** so heat wavs a hard time passing throgh. (my results showed the ice cube in the tin foil lost 11 g while the ic cube in the bubble wrap only lost 5g)
