Extracting dna experiment
Nova, an American TVseries, have a great experiment. In this NOVA video short, learn how to extract your own DNA using just a few common household items. Then transfer 3 tbsp of salt water into a clear cup.Step 3: Gargle the salt water for 1 minute.Step 4: Spit the water back into the cup. It is a kind of scientific model, useful in helping us understand how DNA functions, but in reality impossible to see.The structure of a molecule is far too small to be seen with even the most powerful of microscopes.
However, this is not true. Below, we have outlined a simple experiment showing how DNA can be extracted from a strawberry and made visible to the naked eye.

It can easily be seen with the naked eye when collected from thousands of cells.
One of my favorite resources is KidScienceApp. It is truly science fun at your fingertips.I can search for science activities by subject or by ingredients I have on hand. My kids like to look through the experiment list and watch the videos.

DNA is regularly mentioned in the news and isoften featured in TV detective or crime-scene investigation dramas. DNA, alsoknown as DeoxyriboNucleic Acid, is a long molecule that holds the geneticinformation for all living beings, be it vegetable, animal or a simplemicroorganisms. Since DNA is the blueprint for life, everything living contains DNA.For this experiment, we like to use green split peas.
Pour your thin pea-cell soup through a strainer into another container (like a measuring cup).Add 2 tablespoons liquid detergent (about 30ml) and swirl to mix.Let the mixture sit for 5-10 minutes.Pour the mixture into test tubes or other sm.
