Hypothesis:I thought that the bubble were just water and dish washing detergent but it was actually gas from the gas tap and it was also dishwasher detergent. I thought it would go on your hands and then use the liter to light it up and I already knew that you take your hand apart when it gets to hot on your hands. That's what I thought
Equipment
- Bunsen Burner tube
- Das
- Detergent
- Water
Method:
- Put some water in to a container and squirt in some detergent.
- Connect the gas hose to the taps and make gas bubbles in the water.
- Rub cold water on your hands,wrists,and just before you elbows.
- Scoop up bubbles in the container into the palm of your cupped hands.
- Stand with your hands reaching out in front of you, with your palms and bubbles facing up.
- Light your hands.
- DONT TRY THIS AT HOME
Results: the hands of the person burst into flames without burning their hands.
Discussion: The gas in the bubbles burned.
Conclusion: The safety glasses and equipment like water on your wrists stopped anyone from getting burnt. By listening to the teachers instructions the method was clear.
You have produced a very tidy report. I like the way you have formed a hypotheis and written about your thoughts. Well done.
ReplyDeleteThank you Mr Palmer I really enjoy science and I would deftly take this as a subject in year 9.
