The Scientific method - Write up

Title -  The gummy worms
Purpose: What do you want to learn/find out?
What happened to the calcium chloride when we mix it sodium alginate altogether

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)
I think the calcium chloride and sodium alginate will change

Materials: List everything you will need to conduct your experiment.
Eco cup, calcium chloride sodium, alginate, 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.
1. We mix calcium chloride with water
2. Fill pipettes in with sodium alginate
3. Then the worm juice will change into dot
4. Use pipettes again then put it in the eco cup then it was look like dot.

Analysis/Data: Record what happened during the experiment.
The sodium alginate turned into liquid because it a chemical change.

Conclusion:Review the data and check to see if your hypothesis was correct.
My hypothesis was correct because my alginate did turn into liquid
