Unit 1 Scientific Method: Day 7 - Lab Equipment Scenarios




Let’s review… Fill out the chart below using the pictures below:

Beaker



Used for measuring  and holding liquids.
Erlenmeyer flask



Used for holding liquids; ideal for measuring and mixing
Test tube



To hold small amounts of different liquids
Graduated cylinder



Measures volume of liquids
Hot plate



To heat substances
Funnel



To pour substances into small openings
Pipette



Drop   small amounts of liquid
Stirring rod



Safely stir substances
Wash bottle



Rinse   and clean containers
Burner
Used to heat liquids (usually in test tubes) over a flame







As scientists, we need to understand our knowledge of lab equipment – what’s the use of just knowing about it?

HOW?
1) Underline the actions the person needs to take and ask yourself, “What's needed to do this?”

2) Pick the protective piece of equipment for safety and to avoid spills.

3) Think why?


Let’s Try Together as a Class

As part of a chemistry experiment, Ariana is pouring calcium chloride (small pellets) into a test tube. She is then going to pour water into the test tube.

She will need a beaker, funnel, and test tube because she will need them to complete the chemistry experiment correctly.

She will need goggles, a lab coat, and gloves because she wants to protect her hands, clothes, and eyes.
