Good Morning!!
When you come in, please: TURN IN: Safety Contract Pre-AP Contract Signed Syllabus Sheet (NOT the whole packet) GET OUT: A spare sheet of paper and a pencil WARM UP: Please write 5-7 sentences about what you think Chemistry is about. What are you first impressions of this class? What do you think of Coach Eikrem/what this is going to be like? What have you heard about Chemistry as a subject? In what ways do you think it’ll be difficult or easy? Slide3
Beaker
The primary function of a beaker is to hold and work with liquids
. The beaker is made of specialized glass so it can be heated and cooled without breaking. This type of glass makes the beaker brittle and it must be handled carefully. Slide4
Bunsen Burner
The function of a
bunsen burner is to heat substances. The burner can be regulated by changing the air and gas mixture. . Slide5
Balance
The function of a balance is to mass objects.Slide6
Flask (
erlenmeyer
, Volumetric)The function of a flask is to hold and store liquids. If graduated, it can serve to make approximate measurements of volume. One of the main advantages of a flask is the fact that the mixing of its contents can be done with little or no spillage. This same type of glass makes the flask brittle and it must be handled carefully. A stopper or cover allows for storage of liquids. Slide7
Graduated
CYlinder
Graduated cylinders are specifically designed to make accurate liquid volume measurements. The volume is read from the lowest portion of the meniscus of the liquid; that is, the lowest portion of the convex dip of the liquid as it sits in the graduated cylinder. Graduated cylinders are available in a number of sizes. Slide8
Test Tube
The function of a test tube is to hold a small experiment, which would be used to conduct an investigation. The test tube is made of specialized glass so it can be heated and cooled without breaking. This same type of glass makes the test tube brittle and it must be handled carefully. Slide9
Test Tube Holder
The test tube holder obviously is designed to hold test tubes. However, it can be used to hold pipettes and stirring rods, etc. as well. Slide10
Hot Plate
The function of a hotplate is obvious. Hotplates are often used as an alternative to the
bunsen burner. Some hotplates have a stirring mechanism as part of their design and allows for faster dissolving of some solids by heating and stirring at the same time. Slide11
Thermometer
The thermometer is an instrument for determining temperature. Most laboratory thermometers are calibrated in the SI scale (degrees Celsius)Slide12
Wire Gauze
Holds a beaker when on a ring stand. Slide13
Ring Stand
Used to hold beakers and test tubes when heating or stirring. Come with a clamp for the equipment. Slide14
Crucible
Can heat small amounts of chemicals or materials to a very high temperature without cracking or breaking. Slide15
Clay Triangle
Used to support smaller equipment like a crucible when heating. (Used much like a wire)Slide16
Buret
A
Buret is used for titrations and to measure small amounts of liquid. Can deliver precise amounts of liquid. Slide17
tongs / Test tube holders
Used to hold and support a hot test tube or beaker. Also can be used to hold other materials. Slide18
Watch Glass
Clear, glass. Used as an easy way to see and visualize various liquids. Especially colorful to see any particles
etc in the liquid. Can also hold small amounts of solids. Slide19
Evaporating Dish
The function
of an evaporating dish is to hold small amounts of liquids in order to evaoprate the liqud off to leave the dissolved solid. For example, salt in water. Slide20
