Today I will be sharing with you my Science Experiment that I did with one of my friends called Taylor (Link to her Blog) We had to pick an experiment and test it out and collect data from it and write down our findings and we chose to do a lava lamp here is our planning for it and what we found out.
The scientific method
Question: What do you want to know?
When you make a lava lamp,what causes the baby oil and water to separate?
Purpose: Why do you want to know this? How will the answer to this question help?
Because we want to know why the baby oil and water separate/we are interested.
Background Information: What do you already know about this topic? Is there anything that you need to find out before starting this experiment?
That water and baby oil separates and doesn’t mix. It’s also a great experiment to find out the science behind how a lava lamp works and how they have evolved
Hypothesis: What do you think that will happen and why
The water and the oil will separate and create something that looks like a lava lamp and will
Method: What are the steps to the experiment that you are going to use to answer your question?
1)Fill the bottle a quarter with water.
2)Fill the rest of the bottle with baby oil.
3)Now add your food coloring.
4)After the water is coloring,add a fizzing tablet.
Materials: What equipment will you need?
1 bottle of baby oil and water,fizzier tablets,and food coloring (For color)
And a plastic bottle.
Observations & Results: What do you notice during the experiment? Include any potential changes that need to happen and why? What were the results* of your experiment?
We noticed that the oil and water did not want to mix no matter what we did.We also added a few extra ingredients to see what would happen;such as citric acid and baking soda.
*Ensure that any measurements are properly recorded in a table
Analyse Data & Draw Conclusions: What happened? Why did it happen? Link back to your background information and your hypothesis.
The lava lamp started to fizz and bubbles of water started to rise in the baby oil.When we added the extra things we noticed it began to fizz even more and more bubbles started to rise.
Communicate Your Findings: Present your findings to others.
We found that water was more dense than the oil,or that the water molecules are held closer together than the oil molecules.
Hope you enjoyed and it was really fun to do and until next time. Bye!!!
