Mentos And Coke Experiment
Question: physics vday dorky!?
ok….my bf and i met in physics lab and had physics 1 & 2 together and were lab partners where we developed a great friendship…we’re both science majors and really dorky at heart. anyway, i figured the best gift for valentines day would be one that includes a physics experiement or something (yea, dorky, i know!) i dont even know if this is at all possible! but i figured it would be super cute to incorporate a simple physics experiment for v-day…like, i know how to make slime/gack and stuff like that and i work for the physics dept at school and have access to everything i could ever need. but if theres a way to make a heart or do something physics-y and cool to a picture or make something artistic somehow, please let me know! i dont know how realistic this request is, but if you are dorky enough to have an idea, please share!
Answer: haha – I love it! I’m a huge dork…a bit more in a linguistics/psychology type of way, but I do love physics. What about something with…IDK…ok, yeah I have no idea. The only thing I can think of is building a series of simple machines and moving a ball or something that ends with a message/love note! Ha! That’s the first thing that came to mind.
Lame, I know – but I do wish you the best of luck!
How to Make SLIME!!! (Science Experiment)
Question: Why was there boiled liver in our digestion experiment in science?
In science, we did an experiment on enzymes, we where given 3 boiling tubes with H2O2 in them and a few drops of washing up liquid, we were instructed to put a small piece of raw liver in one boiling tube, one small piece of boiled liver in a boiling tube, and a small piece of carrot into the last, we then had to observe for 5 minutes or so and measure how tall the bubbles were in each tube, the raw liver got the tallest bubbles, But then our teacher asked us all why there was boiled liver in this experiment, and know one could answer.
So i was wondering, why is there boiled liver in our experiment?
Answer: raw liver has catalase ,which degrades H2O2 to form oxygen(the bubbles you see)
the boiled liver serves as a control,the catalase has denatured,so no bubbles.
carrots also have catalase.you would also get the same result with crushed beans.
