How to write a chemistry lab report: The methods used how to write a chemistry lab report:
This non-toxic slime is easy to make and keeps the mess to a minimum. Turn the demo into a lesson with the extension ideas at the end of this article. Safety and teacher tips Even though PVA slime is non-toxic, have students wash their hands after handling slime.
Do not eat slime. Over-aggressive mixing of slime in the plastic bags can lead to rupture, resulting in a slimy mess.
Double-bag the slime formulations or use thicker freezer bags to prevent tears. Slime residue can be removed using warm water, but it may be difficult to remove from carpet. If slime is allowed to dry, water will evaporate from it, leaving behind a thin polymer film. In some cases, it may be easier to remove the dried polymer film than to wash with warm water.
Slime basics Slime is a type of polymer, which is a large molecule formed by many repeating units of smaller molecules.
There are naturally occurring polymers, including cellulose found in wood and paper and starch found in plantsas well as human made polymers, such as polyester used in fabrics and polystyrene used in foam cups.
Polymers are also known as plastics. Slime has properties of both solids and liquids. Like a solid, slime can be formed into a ball and keep its shape.
Poly vinyl alcoholor PVA, is a polymer used to make many plastics. When added to water, borax forms the borate ion. Slime contains water integrated into a solid network of cross-linked polymer chains, forming a gel.
Slime is self-healing, meaning if you break a piece of slime into pieces and squish the pieces back together, they will bond to each other and form one piece again.
Slime is a high-viscosity, non-Newtonian fluid. This means that slime flows differently than liquids like water or oil. Materials per individual or group.Chemistry Lab Resources (for CHM 1XX and 2XX Labs): Parts of a lab report. Introduction. This section tells the reader why you did the experiment.
Include background information that suggest why the topic is of interest and related findings. It should contain the following. The Department of Chemistry at MIT is one of the nation's top chemistry departments.
It has an illustrious history in sharing the MIT tradition of excellence, and it has provided national leadership in chemical education and research throughout the century. Introduction to Chemistry (Stoichiometry) [Enter Course] Overview: This is a complete course in chemical stoichiometry, which is a set of tools chemists use to count molecules and determine the amounts of substances consumed and produced by reactions.
pertinentÝinformation about the scientific concept (this information can come from the lab manual, the textbook, lecture notes, and other sources recommended by the lab manual or teacher; in more advanced labs you may also be expected to cite the findings of previous scientific studies related to the lab).
introduction This experiment is designed to introduce you to the chemistry laboratory and introduce techniques you will need to work effectively this semester.
