How to Extract DNA from Anything Living. First, you need to find something that contains DNA. Since DNA is the blueprint for life, everything living contains DNA. For this experiment, we like to use green split peas. But there are lots of other DNA sources too, such as: Spinach Chicken liver Strawberries Broccoli Certain sources of DNA should not be used, such as: Your family pet, Fido the dog Your little sister's big toe Bugs you caught in the yard Step 1: Blender Insanity! Put in a blender: 1/2 cup of split peas (100ml) 1/8 teaspoon table salt (less than 1ml) 1 cup cold water (200ml) Blend on high for 15 seconds. The blender separates the pea cells from each other, so you now have a really thin pea-cell soup. Step 2: Soapy 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 small glass containers, each about 1/3 full. Why am I adding detergent? Laboratory Equipment. HEURISTICS. How to survive basic chemistry. Learning style management. Class management. How to study for tests. Some pointers on general studying for chemistry. Problem solving skills in chemistry. Some possibly useful pointers on problem solving. In many high schools and colleges the basic chemistry course is the one that causes most concern among students. The most useful advice is to stay up with or ahead of the class. We have found that students do better by having a quiz over a small amount of material. If you are studying with someone, teach it to each other.
Many students find studying with others from the same class is a lot of help. Back to the beginning of Heuristics. Learning is easy for some people. If you have a learning disorder, you must analyze (or have analyzed) exactly what it is and learn your best way to compensate for it. If you have a problem with learning, YOU CAN USE THIS CLASS AS AN EXPERIMENTAL PLACE to find some ways you can adapt to learning these various types of material. About the project | Chem Toddler. Www.chem-toddler.com is a non-profit project with primary purpose is to promote chemistry in educative and entertaining way. There are only two of us continuously working on this, but if it weren’t for help of many others this idea would have never seen the daylight. In the following passages we will try to introduce ourselves, as well as to give you a brief description of our project and intentions. It is our enthusiastic idea to show that chemistry, as an exact science, can be appealing and entertaining to a broad audience and visually inspiring to future chemists, as well as teachers and demonstrators.
After a few years of experience in performing demonstration chemistry experiments we decided to record them, thus making the videos available online. A lot of time and energy have been invested in order to find an original way to perform and film the experiments. The aim of this project is to popularize chemistry and to bring science closer and more understandable and fun for everyone. The Element Sodium. [Click for Isotope Data] Atomic Number: 11 Atomic Weight: 22.98976928 Melting Point: 370.95 K (97.80°C or 208.04°F) Boiling Point: 1156 K (883°C or 1621°F) Density: 0.97 grams per cubic centimeter Phase at Room Temperature: Solid Element Classification: Metal Period Number: 3 Group Number: 1 Group Name: Alkali Metal What's in a name? Say what? History and Uses: Although sodium is the sixth most abundant element on earth and comprises about 2.6% of the earth's crust, it is a very reactive element and is never found free in nature. Sodium is used in the production of titanium, sodamide, sodium cyanide, sodium peroxide, and sodium hydride.
Sodium also forms many useful compounds. Estimated Crustal Abundance: 2.36×104 milligrams per kilogram Estimated Oceanic Abundance: 1.08×104 milligrams per liter Number of Stable Isotopes: 1 (View all isotope data) Ionization Energy: 5.139 eV Oxidation States: +1.
