Lab Safety

Today we have been learning about safety in the science room. First we watched a video to learn about what is expected in the science room. Then had to draw a circle on all of the dangerous things in a diagram. After a few minutes we all came together and talked about all the dangerous things in the diagram. Here is a photo of the diagram with circles the red circles are the one I found myself and the orange are ones the whole class found.

Here is a link to the video we watched for this activity.

How To Be Safe in Science

Planing

Aim: I want to find out to be safe how to be safe in science

Equipment:

• Bucket
• Water
• Detergent
• Rubber Tube
• Safety glasses
• Gas tap
• Lighter

Method:

1.  Get a big bucket
2. Put a good squirt of detergent into the bucket
3. Full the bucket half way with cold water
4. If you have lose cloths take it off, pull your sleeves up and tie your hair up into a ponytail if you have long hair.

Doing

Being set on fire was very scary the sudden heat burning your hands, the bright as the sun flames leaping up into the air, the terrifying black smoke lingering on the roof slowly disappears. Then as quickly as it starts if dies as you move your hands apart.

Explain

I wet my hands because fire and water do not mix so you do not burn. We roll up our sleeves to make sure not to burn our clothes. I was scared because of the adrenaline running though me as the fire started. Adrenaline is an old reaction it has been in us since we where in the stone age, the fight or fight of survival. Why don't fire burn in a circle? Fire burns upwards because the fire is made of gas and it is lighter than air and so the air pushes the fire upwards.
