Science Basics
These are the key information to know for Unit Zero - Science Basics
| Question | Answer |
|---|---|
| what is the most important component to a successful science activity | safety |
| what is your responsibility | your safety and the safety of other classmates |
| what must be obtained before attempting an activity | teachers permission |
| what do you always need when chemicals are used in the experiment | safety glasses must always be worn |
| what do students need to do while during an experiment | stand because u are able to react faster if something were to spill for example |
| what must be secured when you are doing an activity | long hair and loose sleeves because they may come into contact with chemicals or fire |
| what do lab desks need to be clear of | loose papers and their should be no clutter in general |
| when returning equipment to the proper location what should you do | make sure its clean before returning it |
| where do dispose broken glass | container labeled broken glassware |
| at the lab bench after an experiments done what needs to be done | wiped down |
| what need to be washed at the end of the experiment | hands |
| when you use a Bunsen burner what do you never do | leave the flame unattended |
| what need to be kept away from flames or sparks | combustible materials such as alcohol |
| when heating chemicals the tube should always be | directed away from people |
| what need to be in reach of in all times | fire blanket and fire extinguisher |
| what do you need to know the proper use of | fire blanket, extinguisher and alarm |
| what do you need to do before handling chemicals | read the labels |
| what do u need to be able to recognize | safety symbols |
| what should you never do with excess chemicals | return excess chemicals to original container |
| why do you need to replace lids on the container | some chemicals react with air or moisture in the air |
| if a chemical is spilled what do you need to do | tell Mr. Scott and wait for his instructions |
| what do you do with excess chemicals | you dispose of it the way your teacher has told you and should never leave unused chemicals in the sinks |
| what do safety symbols do | tell you possible dangers and remind you to work carefully |
| what should you do whenever in the class | follow all instructions given by teacher, and let them know if any accident occurs. |
| what do you never do | an unauthorized experiment |
| animal safety | only handle them with teacher permission, treat humanly and wash hands after |
| plant safety | don't eat plants, and consider that plants could harmful |
| you should you never do | enter store room without permission, take chemicals from lab, and touch any materials until your instructed to do so |
| what does the lab not have time for | practical joke, horseplay |
| what should you know the locations of | fire extinguisher, fire blanket, shower, eye wash, and first aid kit |
| what are beakers used for | used to hole liquids not to measure |
| crucible | used to heat substances to a very high temperature |
| electric scale | measure mass |
| Erlenmeyer flask | used to hold liquid not for measuring, pouring liquids, combines with rubber stopper to store sample |
| evaporating dish | to observe the process of evaporation in a controlled environment |
| eye dropper | used to transfer small amounts of liquid |
| forceps | used to used to grab, hold or lift particles and specimens |
| funnel | used for pouring liquids or fine grained solids into containers |
| graduated cylinder | measure liquids, only moderately accurate |
| hot plate | heats up substances fairly even heat distribution |
| mortar and pestle | used to crush or grind materials into a fine powder by hand |
| petri dish | used to grow small bacteria cultures and microorganisms |
| pipette | used to dispose a small amount of liquid good accuracy |
| retort stand | used to hold objects such a test tube often used while heating |
| rubber stopper | used on top of flasks and test tubes to trap heat, gas or particles |
| scalpel | very sharp instrument used for dissection |
| spot plate | allows you to conduct mini experiments in a controlled setting |
| test tube | designed to hold small amounts of liquids for use in experiments |
| test tube clamp | used to grab test tubes the might be hot |
| test tube rack | used to hold test tubes |
| thermometer | used to tell temperature (average kinetic energy of the particles) |
| tongs | used to pick up hot things |
| volumetric flask | measure liquids with precision and great accuracy |
| wire mesh | used to heat things up with an even heat distribution, heat spreads throughout the mesh and does not concentrate it on a single point like a flame |
| Disposal Alert | This symbol appears when care must be taken to dispose of materials properly |
| Biological Hazard | This symbol appears when there is fanger involving bacteria, fungi, or protists |
| Open Flame Alert | This symbol appears when use of an open flame could cause a fire or an explosion |
| Thermal Safety | This symbol appears as a reminder to use caution when handling hot objects |
| Sharp Object Safety | This symbol appears when a danger of cuts or punctures caused by the use of sharp objects exists |
| Fume Safety | This symbol appears when chemicals or chemical reactions could cause dangerous fumes |
| Electrical Safety | This symbol appears when care should be taken when using electrical equipment |
| Radioactive Safety | This symbol appears when radioactive materials are used |
| Clothing Protection Safety | This symbol appears when substances used could stain or burn clothing |
| Fire Safety | This symbol appears when care should be taken around open flames |
| Explosion Safety | This symbol appears when the misuse of chemicals could cause an explosion |
| Eye Safety | This symbol appears when a danger to the eyes exists. Safety goggles should be worn when this symbol appears. |
| Poison Safety | This symbol appears when poisonous substances are used |
| Chemical Safety | This symbol appears when chemicals used can cause burn or are poisonous if absorbed through the skin |
