Posed Question: What are the PH levels of 5 items around the house.
(students will each bring in 1 or 2 item from their home to test the PH level)
Hypothesis: In testing 5 household items, ________, ________ and _______ will test to be acids while ______ and ___________ will test to be bases.
Design an Experiment:
- List your 5 items here
- Hydrion Paper
- Holding the hydrion paper with the forceps dip an unused paper into one of the 5 items.
- Compare the color of the hydrion paper to the pH scale to determine if it is an acid, base or neutral.
- Repeat steps 1 and 2 with a new hydrion paper and another item.
(Items will be different depending on what students brought in to test.)
Bring in your item to test for tomorrow's pH lab
Don't forget to bring in your item to test in the lab!
