- The Element Advertising Company - Students are assigned an element and must promote it in a contest like environment. O.K. here's the deal, you will pick an element from a hat. Your group must run an ad campaign for this element. Promoting its beneficial qualities & uses. Your trying to make the community (your school) find your element appealing. Your target audience is the school including fellow students (throughout the building), teachers, hall monitors, all the way up to and including your principal. At the end of your campaign a survey will be given throughout the building to assess which element has the best public opinion due to your efforts. No one else in the building will have your element so it's in your hands.
- The Homemade Atom - Have your classes make an atom. Put them all over the classroom ceiling and make your own periodic table. What is your element's: 1) atomic number 2) Mass Number? How Many 3a) Neutrons 3b) Electrons 3c) Protons does your element have?
- Up, Up and Away! - Students make a warm air balloons to investigate gas laws. Why do certain gases allow a balloon to rise?
- What's going on here? - This station lab, examines chemical and physical changes. What happens to matter when it undergoes a physical and chemical change?
- WOW, That's Hot and Cold! - Examines endothermic versus exothermic reactions. Which of the chemical reactions made in this lab are endothermic & which are exothermic?
Important Things to Know about Chemistry Lab Equipment
The first thing you should always have in mind while working in a chemistry lab is to be careful. Simple mistakes and mishandling of equipment can be dangerous for you and those working around you.
Anyone working in a laboratory, whether students or teachers, should have proper guidance about every piece of equipment used in a lab before handling them. Knowledge about their proper use and handling will result in successful and fun experiments and prevent mishaps. A controlled facility with all the essential safety equipment like eyewash stations and fire extinguishers is necessary to reduce any chances of an accident.
Here is a guide to essential chemistry lab equipment, their specific uses, and some crucial things you need to know before using them.
Cylindrical glass apparatus with a flat bottom and a small spout on top. Beakers are the essentials of every chemistry lab for mixing or heating. It has markings to measure volumes of liquid, although not accurate. It comes in various sizes and is used to store liquids or pour them into another container.A glass beaker allows better observation of its contents than a plastic beaker. It doesn't have a lid, so there are high chances of liquid splashing from the container. So it is recommended to cover it using a watch glass when required.
Conical flasks, also known as Erlenmeyer Flasks, have a flat bottom and long narrow neck. The slim neck allows gentle swirling of the liquid inside without spilling it. It can be used to heat its contents on a Bunsen burner or while clamped to a ring holder. A glass or rubber stopper helps cover the mouth, but remember not to heat the apparatus with the plug. It will cause pressure buildup and will cause it to explode.
Test tubes are used in almost every experiment we perform in a chemistry lab. It is cylindrical and extended with a round bottom and an open end. They have a wide range of uses from storing, heating, observing its contents, and holding chemicals for further experiments. The narrow pipe-like shape doesn't allow gases to escape from the tube rapidly, so it is recommended to tilt it at a 45° angle while heating it.
It is a concave piece of glass used for observation, weighing solids, and heating small amounts of substances, and it is also used as a cover for beakers. The thin glass is very fragile and breaks easily, so proper handling is necessary while using it.
Funnels used in laboratories can be made of glass or plastic. They pour liquids into containers with narrow mouths like test tubes and conical flasks. They come in various shapes and sizes and can be long or short stems, thistles, and dropping funnels. It is a delicate piece of equipment, and its thin and long neck is susceptible to breaking easily.
A graduated cylinder (volumetric cylinder or measuring cylinder) is used to measure liquids accurately since they have several markings on their surface. They have a broad base for stability and a spout for pouring liquid and are solely used to measure chemicals. They come in various sizes. While measuring liquid volume in a graduated cylinder, make sure to take into consideration the meniscus of the liquid.
They have a flat bottom, round flask, and a long neck and are used to hold a specific amount of liquid. They have a marking at the base of their neck. Volumetric flasks help prepares solutions of precise volume. The flask comes with a particular temperature requirement. After filling it, a dropper is used to add small quantities of liquid to make up for the mark.
It is a long cylindrical tube with one open end and the other narrow end which tapers to a pointed opening. They come in small volumes like 1 ml, 10 ml, or 25 ml. A stopcock is sometimes present to allow slow liquid release. It is used to measure and deliver small, precise amounts of liquids. Make sure that you properly rinse the burette and stop cock before using it, to avoid any contact with a previously held chemical.
Droppers are made of plastic or glass. They have a small nozzle on one end and a rubber holder or bulb on the other. As their name indicates, they are used to adding liquids drop by drop to equipment.
These are cylindrical, long, and narrow pipes with one tapered end. They are used to measure and transfer small and precise liquids and solutions. Specific errors can happen in the handling of pipettes. Make sure you have them appropriately cleaned to stop contamination. Never leave them lying around, and store them vertically.
It is used for heating and sterilizing lab equipment. The burner produces a single flame with the desired intensity. It is dangerous equipment and requires careful handling. Inspect the gas valve and tubing of the burner before lighting it. Use a wire gauze to protect the glassware from extreme temperatures. Always use an iron clamp while heating an apparatus on a Bunsen burner.
These pieces of equipment are required in any basic chemistry lab; a lot can go wrong with simple mishandling and lack of knowledge. So, proper guidance is essential before initiating any lab experiment.
