So, I spent the last week performing labs in my kitchen. I put off doing 13 labs for my physiology course online until just this last week. I got them all done though. Stressful as it was, there were some fun ones.

Here are a few of the more exciting ones.

DNA isolation using household chemicals.

-chop liver
-mix clothing detergent, baking soda, salt and water.
-mix with liver for 4 minutes
-filter through coffee filter
-throw away filter and keep liquid
-layer 95% rubbing alcohol on top of the liquid

then you get dna where the alcohol meets the liquid.










Another really nifty lab was done with nothing but red cabbage, lemon juice and ammonia.

-chop red cabbage
-boil 2 cups red cabbage in 1 cup water
-collect the liquid... it is deep purple.
-when you add lemon juice it turns bright pink
-when you ad ammonia it turns green








These were the fun labs out of the lot. The rest were not very fun at all.

Woah....sweetness about the liver. I did the cabbage experiment in my Biology course several years ago. I think that was my favourite lab too.
