Disappearing Penny ADI CEJ

You can use your disappearing penny notes, your ADI board, and the student checklist to complete your CEJ. You will have two attempts on each section. You must ADD MORE writing to the second attempt or it will not let you submit. You must finish your claim and evidence before a text box will appear for your justification. Try your best on spelling and punctuation. Don't be afraid to ask Ditto (the green AI man on the right) for help.

The first sentence of this answer should contain your claim. The mass of the original substance is the ________ of the new substance. THEN answer the following question. Describe your data table/ bar graph (honors only) in words. Talk through the entire experiment. Then explain the observations seen in each reaction.

Justify how your mass before the reaction and your mass after the reaction are similar. Explain how this follows the law of conservation of mass. If your numbers are not exactly the same before and after, explain why.
