Science and its uses

This may seem obvious, but people often disregard safety protocols for one reason or another, putting themselves and those around them in danger.


The best thing you can do is to make sure you follow all safety protocols at all times. Safety goggles are required wear in all chemistry labs. Not wearing them puts you in danger of eye irritation and possibly blindness in the case of an accident.

A small droplet of acid could splash out of the container at any time. Better safe than permanently blinded! Latex gloves should be used when there is a possibility of corrosive chemicals spilling onto your hands. A lab apron or coat can also prevent injury in case of spills or splashes.

Never wear open-toed shoes or sandals in a lab. Beakers A beaker is a common container in most labs. It is used for mixing, stirring, and heating chemicals. Most beakers have spouts on their rims to aid in pouring. They also commonly have lips around their rims and markings to measure the volume they contain, although they are not a precise way to measure liquids.

Beakers come in a wide range of sizes. Because of the lip that runs around the rim, a lid for a beaker does not exist. However, a watch glass discussed below can be used to cover the opening to prevent contamination or splashing.

Erlenmeyer flasks, AKA conical flasks Also known as a conical flask, the Erlenmeyer flask was named after its inventor in It has a narrow neck and expands toward its base. This allows easy mixing and swirling of the flask without too much risk of spilling. The narrow opening also allows for the use of a rubber or glass stopper.

It can easily be clamped to a ring stand discussed below as well as heated or shaken mechanically. Once again, the marks on the side are meant primarily for estimation rather than precision. An important safety tip here is to never heat this flask while it is capped.

This could cause a pressure build-up that could result in explosion. Florence flasks, AKA boiling flasks Also known as a boiling flask, the Florence flask has a round bottom and a long neck. It is used to hold liquids and can be easily swirled and heated.

It can also easily be capped by rubber or glass stoppers. Once again, safety dictates that this flask never be heated when capped.

Scientists predicted in the s that a key fingerprint of anthropogenic climate change would be found in the ocean.

If they were correct that increases in greenhouse gases were changing how much heat was coming into the system, then the component with the biggest heat capacity, the oceans, is where most of that heat would end up.

For example, we know that only 81 percent of Asian-American high school students and 71 percent of white high school students attend high schools where the full range of math and science courses are offered (Algebra I, geometry, Algebra II, calculus, biology, chemistry, and physics).
