Gummy bear lab

How will a gummy bear be affected by water, salt water and vinegar?

Research

• Gummy bears are made from a mixture of sugar, glucose syrup, starch, food coloring, citric acid, vitamin C, gelatin and added flavoring.

• Gelatin absorbs water to a certain extent. There is a limit to how much water gelatin can hold.

• Salt is a solute and draws water towards it. Water moves towards the direction where there is more salt and less water.

• Vinegar is an acid and is corrosive. It can cause various substance to break down.

Multiple Choice

What does gelatin absorb?

• water

• salt

• vinegar

Multiple Choice

What does salt do with water?

• pushes water away

• draws water towards it

Multiple Choice

Vinegar is a corrosive so it

• makes things sticky

• makes things come together

• makes things break down

Hypothesis

You use what you have learned in the research to make an educated guess about what you think will happen. Remember, you hypothesis can be correct and wrong.

What is two materials we will need for the lab?

Experiment

• Collect materials

• Prepare cups and label: water, salt water, vinegar, and control.

• Measure length and mass of each gummy bear. Record in data table.

• Place one gummy bear in each solution.

• The following day, record observations of each gummy bear and measure length, and mass of each gummy bear.

• Find the percent increase in height and mass. Record on data table.

• Draw a conclusion.
