Room 1 Scientists!

Last week Room 1 did the Blobs in a Bottle experiment (commonly know as Lava Lamps) in Chemistry. It was awesome! Below is some photos of the experiment and our findings!

                                                 Blobs In A Bottle!

Question:

1. Does the temperature of the water affect the reaction?

Hypothesis:

I think the fizzing tablet will react violently and quickly with the other contents when the water is warm.

Observations

It reacted violently and quickly, giving a spectacular show!

Conclusion:

My hypothesis was correct. My groups bottle did react violently and quickly with warmer water.

Question:

Does the size of the tablet pieces affect the number of blobs produced?

Hypothesis:

I think that if you put the whole tablet in at once it will bubble more and faster.

Procedure:

First add 200ml of water in the empty bottle then add the oil until it’s about ¾ of the way up and let it settle. After you have let the oil settle add a few drops of food colouring and let that settle as well. Next, add any tablet that fizzes up into the bottle and watch the bubbles shoot up.

Observations:

The bigger the tablet the faster the bubbles shot up.

Conclusion:

My hypothesis was correct because if you add the whole tablet in at once the faster the bubbles shoot up.

What is happening and why?

The tablet is releasing gas as it dissolves causing the bubbles to rise up and float back down.
