Most ELA, Math and Science teachers don't have
more than 100 State Tests on their shoulders
- and they enjoy anywhere from 60 to 90 minutes to teach their class.
But I've been whipping the State
while teaching an average of 110 students per year
- and with only about 38 minutes for science class!
It's a matter of public record:
I've crushed the State by 17 to 32 points, and by an average
of 23 points over a 5-year stretch.
And I'm North Carolina's 2016 Top-Scoring Science Teacher.
I've done this in a High-Poverty Title 1 school with:
No Teaching Assistants,
No Remediation Class,
and No Test-Prep books or programs.
So what are my kids doing???

Lesson and Student Tasks:
pH of COMMON SUBSTANCES, MEASUREMENT & pH INDICATORS + QUIZ
Teachers have been provided two blank Data Trends Tables to use for most pH inquiry that your class or student lab-groups might conduct. These Tables allow for studying up to 7 samples.
Table A contains 42 empty cells for entering data that covers the identity of the 7 Samples and the:
Color-change result from using Purple Cabbage Juice indicator
Color-change result from using Neutral Litmus Paper indicator
Color-change result from using Red Litmus Paper indicator
Color-change result from using Universal Indicator Solution
Table B contains 63 empty cells for entering more precise data that covers the identity of the 7 Samples, plus the:
A, B or N designation from using Gold-colored Acid, Neutral and Base Litmus Paper – and the corresponding pH range
Universal single-digit & uni-color paper pH or range
Universal single-digit & multi-color strip pH or range
Universal two-digit (tenths) paper/strip pH or range
Universal three-digit (hundredths) paper/strip pH or range
Calibrated pH Meter reading
Conclusion as Acidic, Neutral or Basic
Note: for obvious reasons, there is NO Answer Key for these two, blank, inquiry Tables – because the extent of inquiry and the results are entirely up to you, your supplies and your time. And that means the results are entirely up to you and your students. I’ve merely created a product that helps facilitate pH inquiry or labs, by covering the metrics most commonly available to teachers. Thus, there is NO key – but there is a very handy lab sheet to help your students organize their results.
In addition to perhaps filling out the above, blank pH inquiry Data Tables,
1) Fill in 34 cells in a Data Trends Table or Variable Relationships Table
Classify 10 Common Substances as being Acidic, Neutral or Basic, based on the provided pH
Classify the Color Change from using Neutral Litmus paper for 8 of those Common Substances – based on the pattern
discerned from any provided results
Classify the Color Change from using Red Litmus paper for 8 of those Common Substances – based on the pattern
discerned from any provided results
Classify the Color Change from using Blue Litmus paper for 8 of those Common Substances – based on the pattern
discerned from any provided results
2) Use their preceding completed Data Trends Table from Step 1, Teacher assistance and good `ol Common Sense to fill in 20 cells in a Summary Comparison Table, comparing various Acid vs. Base characteristics:
Relative Concentration: [H3O+] > [OH-] or [H3O+] < [OH-]
pH < 7 or pH > 7
Red Litmus paper: Stays Pink/Red or Turns Blue/Violet
Blue Litmus paper: Stays Blue/Violet or Turns Pink/Red
Neutral (purple) Litmus Paper: Turns Pink/Red or Turns Blue/Violet
Purple Cabbage Juice: Turns Pink-Red or Turns Blue-Green
Feel: Sticky & Squeaky or Slippery & Smooth (Warning: DON’T touch chemicals with bare hands!)
Taste: Sour or Bitter (Warning: DON’T taste chemicals!)
Check box if they’re in Fruit Juice, and react with Carbonate-based Baking Soda; Chalk; Shells; Limestone & Marble rocks to
produce CO2 gas bubbles
Check box if they’re in in Soap; Laundry Detergent; Ammonia, Bleach; Drain Cleaner & Oven Cleaner, and react with/remove
Grease & Oils
3) Answer a 50-question quiz featuring 46 multiple-choice questions and 4 fill-in-the-blank questions
4) Be compelled to present their work in a neat & orderly format
5) Be trained to methodically & systematically Understand and Explain pH, and designations such as Acidic, Neutral & Basic as they relate to pH; relative Concentrations of [H3O+] and [OH-]; color changes from pH indicators; and readings from pH meters
Note: These are NOT involved pH or pOH calculations.
There are NO Henderson-Hasselbalch equations.
Now THAT’s what I call ‘putting the w-o-r-k back in WORKsheets!’
