Slime Lab

Vocabulary

100

What is the independent variable in our slime lab?

The amount of Borax

200

What does “dependent variable” mean?

The part that is being measured.

300

Name one control variable in our experiment.

Type of Glue, Materials

400

What is a hypothesis? Give an example.

- Educated Guess

500

Explain the difference between independent and dependent variables using slime as an example.

• The independent variable is what you change (amount of activator), and the dependent variable is what you observe (slime texture).

Materials

100

What main ingredient did we use to make slime?

• Glue was the main ingredient used to make slime.

200

How many mL of glue did each trial use?

• 200 Points: Each trial used about 15ml+ of glue.

300

What tool did we use to measure the activator?

We used a beaker to measure the activator.

400

Why did we divide the glue into three containers?

• To test different amounts of activator while keeping the glue amount the same.

500

If you only had 1 tbsp of glue, how would you adjust the experiment?

• You would reduce the amount of activator proportionally or only test one trial.

Procedure

100

How many trials did each team complete?

• 100 Points: Each team completed 3 trials.

200

What did we change in each trial?

• 200 Points: The amount of activator was changed in each trial.

300

What stayed the same in each trial?

• 300 Points: The amount of glue, type of glue, and mixing time stayed the same.

400

What was the first step in the experiment?

• 400 Points: The first step was to measure and divide the glue into three containers.

500

Describe the full procedure from start to finish.

• 500 Points: Measure glue, divide into 3 parts, add different activator amounts, mix, observe, and record data.

Data & Observations

100

What did you observe when you added 1 tbsp of activator?

• 100 Points: The slime was soft and slightly sticky with 1 tbsp of activator.

200

Which trial made the stretchiest slime?

• 200 Points: The 2 tbsp trial usually made the stretchiest slime.

300

How did the slime change as you added more activator?

• 300 Points: The slime became firmer and less sticky as more activator was added.

400

What kind of data did you record in the table?

• 400 Points: We recorded texture for each trial.

500

Compare the texture of slime from Trial 1 and Trial 3. What caused the difference?

• 500 Points: Trial 1 was softer and stickier; Trial 3 was firmer. The difference was caused by the amount of activator.
