Chemistry Slide2

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

Biohazard Symbol

Highly

CorrosivE

Highly corrosive will affect your skin, and can “eat away” at tissue.

Slide22

Highly Flammable
