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

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

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.
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 wont overﬂow and cause accidents. • Step 2- Use a ﬂask clamp to hold the ﬂask if it is exposed to high heat, such as when youll want to bring the liquid within the ﬂask to a boil. Dont use a clamp when swirling a liquid within the ﬂask. • Step 3- Clean the ﬂask when youre ﬁnished using it. Do not add new chemicals into a used ﬂask until the ﬂask has been washed and dried properly.

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.
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 rooms 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. Youll 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 dont let the liquid come into contact with your skin. After, discard the dish.

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.
How to use a Pipette?• Step 1- Firstly, youll 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.

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.
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.
