Scientific Tools/Equipment

Measuring Volume - Graduated cylinder is the most accurate to measure liquids Flask is used for mixing/swirling, rough measurements Beaker is used for experiments, rough measurements

Measuring length - Metric ruler measure length, width, height up to 30 cm Meter stick measures up to 1 m *can be used with another meter stick for up to various lengths *tape measures is useful for long distances

Measuring mass and weight- Balance (triple beam or digital) determines mass Spring scale determines weight

Time - Stop watch (timer) measures time interval between two events *many different styles

Temperature - Thermometer measures temperature *some are ºC and ºF, and some only ºC

Observation for experiments- Test tube rack holds test tubes in an organized and safe fashion Test tube brush safely cleans test tubes Test tube holder safely holds test tubes for transferring Test tube used for experiments *test tubes come in a variety of sizes

Tools for Observation - Hand lens used to magnify objects Petri dish used to grow bacteria or holds objects *glass or plastic Watch glass covers glassware – safe to look

Changing matter - Hot plate heats substances – solid to liquid, liquid to gas, etc. Mortar and pestle crushes substances

Essential tools - Funnel used to transfer to one substance into another substance Dropper/pipette used to transfer small amounts of a substance *dropper bottle holds liquid with lid as the pipette Stir rod used to mix solutions Forceps (tweezers) used for picking up substances

Tongs used to move beakers or flasks Stoppers used to plug flasks, test tubes, etc. *cork or rubber *holes or no holes Goggles used to protect eyes

Dissecting - Pins used to hold organism for viewing Scissors used to cut organism Probe used to point to organisms parts Scalpel used to cut organism Pan used to hold organism for dissecting

Microscopy - Slide used to place object for viewing Cover slip used to cover the object for viewing Microscope used to observe small objects *dissecting scope *microscope *scanning electron microscopes

And if anything catches on fire…there’s the fire extinguished!
