The Scientific Method - Write Up

Title - Gummy worm experiment
Purpose: What do you want to learn/find out?
I wanted to learn how the sodium alginate turned into solid.

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 Sodium Alginate that will mix with the water that has Calcium Chloride will turn into a solid or it will just stay as a liquid.

Materials: List everything you will need to conduct your experiment.
Pipette, Sodium Alginate, Calcium Chloride, Water and Eco cups (size big and small).

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.Mix water with Calcium Chloride.
2. Fill the pipette with sodium alginate (which originates from seaweed.
3. Fill the water mixed with calcium chloride with Sodium alginate.
4. Watch the Sodium alginate turn into a solid.

Analysis/Data: Record what happened during the experiment.
What happened during the experiment was the Sodium alginate turned into a solid and it became touchable and it felt weird like actual gummy worms.

Conclusion:Review the data and check to see if your hypothesis was correct.
My Hypothesis was correct because the sodium alginate did turn into a solid.
