My Scientific method

Title - My Gummy Worm Experiment
Purpose: What do you want to learn/find out?
What happens when you put in the sodium alginate and also with the calcium chloride solution .

Hypothesis: Try to predict the answer to the problem. Another term for hypothesis is ‘educated guess’. This is usually stated like ” If I…(do something) then…(this will occur)
It will only change into a gummy worm if you if you put it in the right order.  When you mix the solution of calcium chloride and water before you put in the alginate.

Materials: List everything you will need to conduct your experiment.
Calcium,chloride,sodium alginate, polymer chemical reaction, pipettes

Experiment procedure: The fun part! Design a test or procedure to confirm or disprove your hypothesis. Write down each step so that someone else could do the same experiment.
Step one: Mixing the calcium chloride water and then we stirred until it dissolved.
Step two: We picked the sodium alginate with the pipettes.
Step three: next thing you need to do is that you have to watch it dissolve.  

Analysis/Data: Record what happened during the experiment.
When we picked up the gummy worm it was hard and gummy and also squishy.   
Yes the experiment was correct because we checked it all out before we moved on.

Conclusion:Review the data and check to see if your hypothesis was correct.
In the experiment it was gonna turn into a soft gummy worm.
