Triple Beam Balance
D) Is a scale that measure mass.
Q) Why does the triple beam balance measure mass?
erlenmeyer flask- a flask with a big bottom and a small top. The erlenmeyer flask is used during experements.
test tube- used to hold liquid in. A test tube holds liquid in it to measure.
graduated cylinder- a cylinder used to take exact measurments on liquid. The graduated cylinder gives a precise reading.
bunsen burner- a way to heat stuff. The bunsen burner is used to heat up liquids.
triple beam balance- a balancer that has 3 beams. A triple beam balance is used to balance stuff, with its 3 beams.
Erlenmeyer Flask – used to measure liquid & prevent liquids from splashing or giving off noxious fumes
“Use the Erlenmeyer flask with the acid.”
Test tube – used to mix, measure, and heat substances with accurate measurement
“Pour that in the test-tube until we need it.”
Graduated cylinder – marked with a scale for measurement. Used to measure volume
“Measure the water in the graduated cylinder to make sure you don’t put too much in.”
Bunsen Burner – source of gas heat
“Use the Bunsen Burner to heat up the gas.”
Triple Beam Balance – scale used to measure objects (usually in metrics)
“How heavy did the triple beam balance say that rock was?”
(I was absent Tuesday)
Erlenmeyer Flask- a flask having a wide base, narrow neck, convenient in laboratory experimentation for swirling liquids by hand.
The Erlenmeyer Flask was used for combining two kinds of chemicals.
Test Tube- a cylindrical round-bottomed glass tube open at one end.
In Test Tube A was the element sulfur.
Graduated Cylinder- a container for liquid with a wider base gradually narrowing to the top and marked with a graded scale
There is 50 mililiters of water in graduated cylinder.
Bunsen Bruner-a type of gas burner, in which is very hot, practically nonluminous flame is obtained by allowing air to enter at the base and mix with the gas
The Bunsen Burner was turned up to highest temperature it could reach.
Triple Beam Balance-a type of balance commonly used in the laboratory to determine the mass of items or things.
The mass of an apple is 12 grams.
Erlenmeyer Flask- a flask having a wide base, narrow neck, and conical form, convenient in laboratory experimentation for swirling liquids by hand
In class today we were told that we were going to be mixing chemicals, the teacher told us to get out our Erlenmeyer Flask since it is used to swirl liquids by hand.
Test Tube- a hollow cylinder of thin glass with one end closed, used in chemical and biological experimentation and analysis
We were going to do experiments today in science so the teacher handed us each a test tube to use.
Graduated Cylinder- a container for liquid with a wider base gradually narrowing to the top and marked with a graded scale; also called graduated flask
To measure liquids I use a graduated cylinder.
Bunsen Burner- a type of gas burner, commonly used in chemical laboratories, with which a very hot, practically nonluminous flame is obtained by allowing air to enter at the base and mix with the gas.
To heat up the chemicals we used the Bunsen Burner.
Triple Beam Balence- It has a beam which is supported by a fulcrum
To weigh the iron block, I used the triple beam balence.
1. A erlenmeyer flask is used not for percise measurements and has a thinner top so chemicals do not get anywere.
2. The test tube is use to store chemicals and has its very own tongs.
3. Graduated Cylindersare used for percise measurements.
4. I wonder how hot a bunsen burner is when it is heated?
5. Triple beams balances are so fun to play with.
