Chemical In You're Eye

How could it happen ? 

It could splash up when you put a chemical in something and it splashes up.

What might happen if we do nothing about it ?

It could make you blind.

What can we do to prevent it ?

Always were safety glasses.

What should you do if it is to happen ?

Immediately wash the eye in water.

Test Tube Holder

Test Tube Holder

The test tube holder is a piece of laboratory equipment that is used to hold test tubes. They are used by squeezing the handles to open the other end, and inserting the test tube. Test tube holders are typically used for holding the test tube, and when heating the test tube is necessary, or for when dangerous materials are being handled. Test tube holders are common in all laboratories. Test tube holders can be made out of wood, plastic, styrofoam, metal or brass 

Coming Soon...

This week, the class have "adopted" a piece of laboratory equipment. Their small groups have to find everything out about it, and make a presentation to post on this blog:

1. What is it called?
2. What does it look like?
3. How is it drawn (in 2D)?
4. What is it used for?

Please give some feedback about their work when they post it.

Electrocution

 - It can kill you.

 - Anything with volts.

 - Gives you a shock I you get electrocuted.

 - Be careful when your around them and make sure that you don't accidentally spill water on the cables.

 - If you see that a wire has been damaged you should switch it off and pull the plug out or tell Mr Nicoll.

 - If someone got electrocuted you would step away from the person and go and tell Mr Nicoll straight away.

Thank you to Maddy for emailing this through to me.

I just want to add this:

Do not touch anyone who has been electrocuted. Someone will turn off the power, then first aid can be administered.

Cuts

What can cause them in the laboratory:

• Fiddling with pins or scissors
• Dropping some glass (eg: a beaker)

To prevent this from happening:

• Wear protective gear when holding something massively sharp.
• Don't fiddle with scissors, pins, knifes if you are using them.

What to do if this does happen:

• If its a sharp big piece of glass hold down onto it because if you take it out it will bleed a lot more but remember to warn the teacher.
• If it is a small cut maybe ask the teacher of you can get a band-aid.

What to use if this does happen:

• band-aid
• ambulance (if you really need to.)
• bandage
• little cut will heal it self with oxygen.

Thank you to Brittany F for emailing this through.

Fire

Fire

These are some things our group came up with:

• A fire can be caused by someone leaning over the bunsen burner with loose clothing.
• If you are burnt by the fire place the affected area under cold water for 10 to 20 minutes.
• If you catch on fire remember to stop, drop and roll!
• If nothing is done about the fire it can burn up the classroom and possibly the building.
• A fire can be put out by using a fire extinguisher.
• Fire is very dangerous and if not treated correctly you can get severely injured and possibly die.
• If the fire is under control you should walk briskly out of the classroom and wait outside for your teacher.
• In the event of a fire some windows should be opened to allow smoke to leave the room reducing smoke build up.
• A fire can be prevented by keeping the bunsen burner flame to yellow when not using it, tucking away loose clothing and being sensible with open flames.

POISON

Britney, Holly, Tim and Olivia

This is what our group did today in science :) =

Poison!!!

1. Posion can kill.
2. Poison is sprayed on plants and grass so when animals eat it, it kills them.
3. Most chemicals have poison in them.
4. Very dangerous if you drink or touch poison.
5. There are many things that contain poison in the lab.
6. You should wear protective gear well handling/ being near poison.

If your working with poison make sure you wash your hands thoroughly.

*Poison is VERY dangerous! And should not be handled by young kids.

If you feel sick after working with poison tell Mr N ASAP.

Chemical Burn

Chemical Burns

This is what we came up with about chemical burns in science today.

• Chemical burns can happen when you are pouring chemicals and it spills on your skin. It will burn your skin really badly.
• Chemical burns can be prevented by wearing protecting gear, cleaning if it spills and being careful.
• If you get a chemical burn you should always tell the teacher. Sometime you can put it under cold water but not always. Putting it under water could make it worse so check with the teacher first.
• If you don't do anything about it you could get badly scared. If it is really bad burn could it can even kill you and you wouldn't want that to happen.

Heat Burn

Liam, Thomas and Lucy-Rose

Heat Burn

How Could It Happen?
- Bunsen burner
- Heated chemicals
- Hot water

How Could It Be Prevented?
- Wearing protective gear
- Being careful around sources of heat

What Should You Do If It Does Happen?
- Tell the teacher
- Put in cold water for at least 10 minutes

What Might Happen If We Do Nothing About It?
- Injuries
- Unsafe environment
- Scars from the burns

These are the ideas we came up with in our group for heat burn!

Danger, Danger!!

Hazards in the Laboratory

We were asked to identify some of the hazards we might find in the laboratory. Then, we shared our ideas with the rest of the group, and then we finally discussed it as a class to make the list you see in the image.

Safety Rules

After we discussed the possible hazards in the laboratory, we we asked to make a list of four important safety rules. We then shared those with the other people with the same-colour paper as us to make a list of ten safety rules. These were written on the board:

9A's Safety Rules

1. No running
2. No eating or drinking
3. Always listen to the teacher
4. Bags in pigeonholes
5. Don't use things without permission
6. Clean up after experiments
7. Be sensible
8. Use safety equipment when needed (like safety goggles)
9. Push chairs in when you leave your desk

Mr Nicoll's Safety Rules

1. Turn Bunsen flames to yellow when not in use
2. Do not taste any chemicals
3. Shoes must be worn at all times
4. Aim experiments away from other people
5. Report any breakages to the teacher straight away
6. Always work on a heatproof board
7. Wash your hands after every experiment
