4. What is a Bunsen Burner used for?
• A Bunsen burner is a device used in
science labs for heating, sterilization, and
for many other uses.
• NOTE sterilization means to make something free from bacteria.

5. Tips before using a Bunsen Burner
• Make sure your clothes are not hanging out or loose.
• Make sure whatever you're heating can be heated
safely without it exploding.
• Keep any flammable items away from your Bunsen
burner.

6. How to use a Bunsen Burner?
• Step 1- Turn the gas on at the start of the gas line. This can be found where the hose fits over the gas line
that sticks out from the wall. You will want to turn it on until you can hear the gas flowing smoothly
through the hose.
• Step 2- Turn on the burner slowly and gently. Once you hear the gas, you can light the Bunsen burner .
Keep your fingers as far from the flame as possible. You need to light it on the side of the Bunsen burner so
that the flame reaches around the flame and away from you.
• Step 3- Once the flame is lit, you can fix the height flame that will be suitable for your experiment. If you are
heating something, you will need to fix the height of the holding tray to the flame. Do not try to fix the flame
to the height of the holding tray.
• Step 4- After the experiment is done and all the data is completed, you will need to turn off the Bunsen
burner. Make sure whatever you are heating is off and holding tray is removed. These chemicals can get very
dangerous when heated, so be careful. Remember to use tongs to remove the glass container and put it far
enough away from the burner to be safe.
• Step 5- Once the glass container is removed, turn off the gas at the Bunsen burner’s base and at the wall.
Once the gas is off, the flame should automatically be extinguished. If it is not, you may have a gas leak.
Make sure the gas is completely off on both sides. If it is off and the flame has not gone out, alert your adult
or teacher immediately.

7. Beaker

9. What is a Beaker used for?
• A beaker is used in science labs for holding,
pouring, storing, measuring and heating
liquid.

10. How to use a Beaker?
• Step 1- Pour liquid into the beaker. Pour liquid slowly to avoid
liquid from splashing anywhere. Use the measurements on the
beaker to help you get the right amount of liquid you need in
your beaker.
• Step 2- Stir the liquid inside with a spoon.
• Step 3- Place the centre of your beaker on a burner or over an
open flame to heat the liquid. Don't fill the beaker more that 1/3
when heating. Also always use safety tongs when handling a
hot beaker.
• Step 4- Pour liquid out of the beaker by using the spout.

11. Florence Flask

13. What is a Florence Flask used for?
• The Florence flask is just like the Beaker but it
is a different shape. In science, the beaker is
used for holding and boiling liquids.

14. How to use a Florence Flask?
• Step 1- Inspect for cracks and damages on your Florence
flask. After, fill the round, flask container half full. So the
chemical in you flask won't overflow and cause accidents.
• Step 2- Use a flask clamp to hold the flask if it is exposed to
high heat, such as when you'll want to bring the liquid
within the flask to a boil. Don't use a clamp when swirling a
liquid within the flask.
• Step 3- Clean the flask when you're finished using it. Do
not add new chemicals into a used flask until the flask has
been washed and dried properly.

15. Petri Dish

17. What is a Petri Dish used for?
• Petri dishes are used by doctors and scientists
for growing things such as bacteria, skin,
and cells. They also can used for storage.

18. How to use a Petri Dish?
• Step 1- Place your petri dish in the refrigerator with the top of your petri dish facing
upside down. After, get your petri dish out from your refrigerator and leave it to sit for
about an hour so the dish can get use to the room's temperature.
• Step 2- Take the top off of the Petri dish and set it aside. Press any bacteria sample gently
onto the agar surface, being careful not to tear or break the surface. You can use any
sample you choose, from a sample gathered on a cotton tipped wipe to "dirty" objects, such
as fingers, coins, and so on. After the sample has been set, replace the top of the Petri dish.
Use masking tape to lock the top of the Petri dish. Label the sample with a marker.
• Step 3- Set the dish somewhere that is very warm. You'll obtain the best results in a place
that is around 100 degrees Fahrenheit. Allow a few days for the bacteria to grow.
• Step 4- Detect the bacteria to your liking. When you are finished with the Petri dish, kill
the bacteria by pouring a small amount of bleach over the bacteria . Hold the dish over the
sink as you do this and don't let the liquid come into contact with your skin. After,
discard the dish.

19. Pipette

liquid goes in and also
releases

21. What is a Pipette used for?
• Pipettes are commonly used in
molecular biology, analytical chemistry
and also medical test purposes. They are
also used in science labs to carry or
measure a specific volume of liquid.

22. How to use a Pipette?
• Step 1- Firstly, you'll need to get liquid you are going to place in
your pipette.
• Step 2-Once you have done that, grab your Pipette and dip it in
liquid. Hold the end of your Pipette, which is called the bulb and
get the amount of liquid in your Pipette.
• Step 3- Once you have the right amount of liquid in your Pipette,
release the bulb and the liquid will stay inside your Pipette.
• Step 4-When you want to release the liquid out from your pipette,
then just hold on to the bulb and the liquid you have inside your
liquid will release.

23. Test Tube

25. What is a Test Tube used for?
• Test tubes are used by chemists and scientist
to hold, mix, or heat small amounts of solid or
liquid chemicals.

26. How to use a Test Tube?
• Step 1-Use tongs to hold the test tube. Wrap the tongs around the
center, and hold firmly but not too tightly. Keep the test tube
away from you at all times, in case of any splashing.
• Step 2- When warming the test tube, hold it over the flame on an
angle, moving it back and forth gently.
• Step 3- Never smell any chemical inside a test tube or look
inside a test tube.
• Step 4- When not using a test tube, place it in a test tube holder .
This will help the test tube from preventing any spillage or
accidents.
