Introducing the

Microscope Accessories

The prepared slide will be used right at the

beginning and again later on in the

detective chapter. Prepared slides are

handy because they are ready-to-use and

they can be quickly pulled out whenever

you want to compare different kinds of

samples.

The pipette is used whenever you want to

drip small amounts of water onto a slide.

On the slide, you will be placing all the

specimens that you want to study under the

microscope. When you do this, you will

cover the specimen with a cover slip in order

to get the best image and protect the

specimens from getting dirty.

Use the sharp dissecting needle (be careful!)

when you want to place or move a specimen

on the slide. The tweezers and sample

container will come in handy when you’re

searching for new specimens.

The objects that you view under the

microscope will have to be very thin in order

for enough light to be able to shine through

them. Some specimens will have to first be

cut into very thin slices so you can study

them under the microscope in cross section.

You can use the slicing tool for this, or a

razor with fabric tape over the part you

hold.
