Junket Temperature Lab Report
Ideal Temperature for junket
Aim- To discover the optimum temperature for junket to solidify
Hypothesis- That the optimum temperature will be between 35-40°C
Independent variable- Temperature (10, 40, 60 degrees)
Dependant variable- Time taken for Junket to set
Control- 2 clearly marker test tubes will be placed under each temperature condition, one with junket and one without, to clear the complication that it might be the temperature that is reacting with the milk and solidifying it instead of the junket.
Safety requirements- * Safety goggles * Clear work space * Proper use of equipment

Collect all equipment and take all safety requirements seriously. 2. Fill 2 250ml beaker with 150ml of water and place it over a Bunsen burner, check one periodically until the temperature has reached 55-60°C then maintain the temperature using a Bunsen burner. Allow the second one to drop to 35-40°C and maintain with a Bunsen burner. 3. Fill 1 250ml beaker with 150ml of water and place ice cubes into the water to lower the temperature to 15-20°C. 4. Separate test tubes into 3 groups of 2.
Place 25 ml of milk into each test tube then mark each one in a group with A or B. (You should have 3 A’s and 3 B’s) 5. Place 2 test tubes in each water bath and allow for milk to raise to temperature of water bath.
When heated place ¼ of a teaspoon of junket powder into the test tubes labelled A.
B will be your control. 6. Begin timing immediately. Making sure to maintain the temperature range throughout the experiment. 7. Check all test tubes to see which ones have solidified, using the ‘tip-test’. Record results.
