14. Activity 2 1. Name at least 2 laboratory apparatus you found inside the lab.2. Can you identify their uses? 3. Why is it important to use laboratory apparatus?
1. Beaker and Watch glasses
2. A beaker is a common container in most labs. It is used for mixing, stirring, and heating chemicals. A watch glass is just a round piece of glass that is slightly concave/convex (think of a lens). It can hold a small amount of liquid or solid. They can be used for evaporation purposes and also can function as a lid for a beaker.
3.Help students learn scientific concepts and to enhance students' interest, motivation, practical skills and problem solving abilities.

18. why is it important to know the uses of laboratory apparatus
It is important to know because we will know what are their functions are and without them, an item cannot be done or achieve.
19. 5 list precautionary measures in using laboratory equipment or apparatus.
Answer:
Basic Safety Rules:
When working in a laboratory, basic safety rules for laboratory conduct should be followed. Many of the most important safety rules are outlined below.
Know locations of laboratory safety showers, eyewashstations, and fire extinguishers. The safety equipment may be located in the hallway near the laboratory entrance.Know emergency exit routes.Avoid skin and eye contact with all chemicals.Minimize all chemical exposures.No horseplay will be tolerated.Assume that all chemicals of unknown toxicity are highly toxic.Post warning signs when unusual hazards, hazardous materials, hazardous equipment, or other special conditions are present.Avoid distracting or startling persons working in the laboratory.Use equipment only for its designated purpose.Combine reagents in their appropriate order, such as adding acid to water.Avoid adding solids to hot liquids.All laboratory personnel should place emphasis on safety and chemical hygiene at all times.Never leave containersof chemicals open.All containersmust have appropriate labels. Unlabeled chemicals should never be used.Do not taste or intentionally sniff chemicals.Never consume and/or store food or beverages or apply cosmetics in areas where hazardous chemicalsare used or stored.Do not use mouth suction for pipetting or starting a siphon.Wash exposed areas of the skin prior to leaving the laboratory.Long hair and loose clothing must be pulled back and secured from entanglement or potential capture.No contact lenses should be worn around hazardous chemicals – even when wearing safety glasses.Laboratory safety glasses or goggles should be worn in any area where chemicals are used or stored. They should also be worn any time there is a chance of splashes or particulates to enter the eye. Closed toe shoes will be worn at all times in the laboratory. Perforated shoes or sandals are not appropriate.Reference

20. if a laboratory apparatus is not properly use how will it affect your experiment
Answer:
the experiment will not be accurate and it will be ruined
21. what is the different apparatus instrument use in laboratory
Answer:
Test Tube
Syringe
Tape
Thermometer
22. Which laboratory apparatus should be used to measure the mass of matter
Answer:
balance
Explanation:
Scientists measure mass with a balance, such as a triple beam balance or electronic balance. In science, the volume of a liquid might be measured with a graduated cylinder.

23. laboratory apparatus used to making smaller objects appear bigger
you can use a microscope if you want to view microorganisms and you can also use magnifying glass just to see details of objects especially if these are not microscopic
24. choose 5 laboratory apparatus you intend to use when you conduct an experiment. briefly describe what your experiment will be about and the use of your chosen laboratory apparatus
Explanation:
C.throw a rockC.throw a rockC.throw a rock
25. 5 laboratory apparatus used for investigation describe their function
1. Microscope:
A microscope is a very basic and needful equipment of biology laboratory. A simple light microscope (compound microscope) is the one, and it uses natural light and a series of magnifying lenses to observe a tiny specimen.
2. Test tubes:
The next very common apparatus are the test tubes. They are usually cylindrical pipes made up of glass, with a circular opening on one side and a rounded bottom on the other side. They come in different sizes but the most common standard size is 18*150 mm. Test tubes are one of the most important apparatus as they are functional from storing to mixing reagents in any chemical or biological reactions.
3. Beakers:
Beakers are another cylindrical utensil made up of glass, with a flat bottom and the upper opening having a spout. They are of varying sizes and are used to hold, heat, or mix substances with the proper measure.
4. Magnifying glass:
As the name suggests, it is used to view enlarged or magnified images of objects or read the small calibrations marked on many equipments. It has a convex lens for object enlargement and usually has a wooden handle to hold it.
5. Volumetric flask:
This is one of the most important equipment of any lab, which is made up of glass and is calibrated to hold a precise volume of liquids at any precise temperature. Different sizes of volumetric flasks are available, each calibrated for exact measurement of liquids and solutions. In chemistry labs, it is mostly used in the preparation of standard solutions.
26. Why is it essential that you know the laboratory apparatus and it’s use?
Answer:
We should always know your lab equipment well before you do any type of experiment because without the proper knowledge of your equipment you will not know how to use your materials or how to correct a mistake that you could make with your equipment. Over and above the reasons mentioned, knowing one's science equipment will only aid in having a successful experiment and might help in correcting errors.

Hope this helps you!!

28. Laboratory apparatus used in in the experiment to measure the pH of the water samples.
Answer:
A laboratory pH meter typically has a special probe capped with a membrane that is sensitive to H+ ion concentrations. The meter reading shows an exact pH value of the solution probed. pH meters are used to measure pH values of water samples, such as determining acidity of rainwater samples.
