What is a beaker used for?
used for mixing substances, lip for pouring and the scale for measuring volume
1 of 20
What can a conical flask and stirring rod do?
Wide base and narrow neck prevents spills and it can be fitted with a bung. stirring rod stirs the liquid without becoming hot. conical flask holds the liquid being heated
2 of 20
What can a Bunsen burner and a heatproof mat do?
it can protect bench from heat and can be used with other hot equipment. Bunsen burner is a source of heat
3 of 20
What are test tubes?
They hold small quantities of substances in a reaction. They need to be stored in test tube racks to prevent contents from spilling out
4 of 20
what is a clamp stand?
clamp stand can hold test tube / other containers at a fixed distance from a heat source
5 of 20
What can a pH meter be used for?
it can measure the pH with a pH meter or a universal indicator solution. it is needed in neutralisation reactions to show when the neutralisation point is reached

What does the piece of filter paper in a filter funnel do?
it separates a solid from a liquid
7 of 20
What is a measuring cylinder used for?
To measure a smaller volume of liquid precisely use narrower cylinder as they come in different sizes
8 of 20
What is a pipette used for?
To measure or transfer small amounts of liquid
9 of 20
Digital balances?
They measure mass in grams or milligrams
10 of 20
what does an AMMETER do?
Measures the current through a circuit component
11 of 20
Filament bulb can be connected to...?
it can be connected in a circuit to show that the circuit is working/ or to investigate its resistance
12 of 20
THERMISTOR?
can be used to control a circuit by acting as a temperature sensor
13 of 20
LIGHT DEPENDENT RESISTOR (LDR)?
can be used to control a circuit by acting as a light sensor
14 of 20
A VOLTMETER?
measures the voltage across a circuit component
15 of 20
A MULTIMETER?
can eb set to read current, voltage or resistance
16 of 20
A RESISTOR?
can be connected in a circuit to reduce the current
17 of 20
What does a microscope allow us to do?
it allows us to see samples and organisms that are too small for the human eye to see alone
18 of 20
putting a GLASS COVER SLIP over the sample does what?
prevents the sample coming into contact with the microscope lens
19 of 20
What are petri dishes used for?
They are used to grow bacteria safely in the laboratory
