Magnifying / Microscope lens
A microscope is a science instrument that uses slides. Slides are small rectangular pieces of glass on which specimens are placed for viewing under the microscope. The slide holds the specimen in place and allows light to pass through for magnification and observation.
If a water slide was dry, the lack of water would increase friction between the slide surface and any riders. This increased friction could make it more difficult for riders to move smoothly down the slide, potentially causing discomfort or slowing down their speed.
Yes, friction is useful on a slide because it helps to slow you down and prevent you from sliding too quickly or uncontrollably. It also provides enough grip for you to stay on the slide without slipping off.
An oceanographer or a fluid dynamics physicist would be most likely to study how energy is transmitted by water waves. They are experts in studying the behavior and movement of water in oceans, seas, and other bodies of water.
You would likely move faster down a waterside due to the reduced friction from the water acting as a lubricant between your body and the slide surface, compared to a regular slide where friction between your body and the slide surface slows you down.

What instrumentProbably a microscope.
You would place a slide on the stage of a microscope.
All brass instruments (except the sousaphone) have slides. They are used to adjust the pitch, sharp of flat. The instrument that is played using a slide is the Trombone. It also has a slide on the back that is used to tune, or adjust pitch.
youd go faster, but the slide would get sticky after a while and would give someone a wedgie or pull their pants down!
.
My guess would probably be designing water slides
an optical telescope
You can use a spray bottle to mist water onto a slide to make it slippery or a hose to wet it more evenly.
That would be the trombone, as it changes notes by use of a slide rather than valves.

I would use a thermometer.
