Title of the Lab: Where's the Evidence?
The guiding question: What are some signs that a chemical reaction has taken place?
Your hypothesis: I think that in each substance there will be a different chemical reaction. Some might be hotter, some my become colder. Maybe even one might overflow. Some of the substances might even change colors.
List of the Materials used:
-Substances
-goggles
- tubes
Data Table with ALL observations:
Analysis of your results. I thought that some of the reactions might explode. One of them just over flowed and the others either got hotter or changed colors. The way i knew that the reaction was over was, one of the substances had bubbles and after it sopped bubbling i knew it was over. After one of the liquids over flowed i knew it couldn't react anymore.
Conclusion: Some signs that showed me that the reaction had started was smoke/heat, color changing, bubbling and so on. Some of the experiments did overflow and some did change color. I think one new substance was formed from all the experiments we did. I think that all the reactions did come to an end, i just don't know because i wasn't in class after the bubbling was still going on.
Further Inquiry: I think that we should have done something more exiting in class, like the elephant toothpaste. I still wonder what would have happened if we added heat to all of the experiments above.
