Modeling Protein Structure
Students examine amino acids and discuss the properties of side chains. In this proteins lesson plan students demonstrate the foldings of peptides.
Curated OER
Chemical Weathering
Students measure the effect of water temperature on the rate of a chemical reaction, similar to the interaction of a weak acid and carbonate rock, using hot water and effervescent antacid tablets.
Curated OER
The Colors of Chemistry
Young scholars investigate the acidity and alkalinity of common household products in an experiment. They use red cabbage juice and litmus paper to show the difference between strong acids and bases as they work with vinegar, dish...

Acids, Alkalis, and Salts
In this acids worksheet, students review the definition of acids, bases, and salts. Students describe the differences between acids and alkalis and define neutralization. This worksheet has 2 short answer and 1 problem to solve.
Curated OER
"pH and the Environment"
Eighth graders experiment and study about acids and bases by becoming involved in direct hands-on learning experiences and then relate those experiences to their own lives. They experience the Ohio River and what can be done to help...
Curated OER
pH Readings and Salinity Readings of Water From Three Locations Within the Neponset River Watershed
Sixth graders test the ph levels of water from three different water environments within the Neponset River Watershed. They discuss the three different water environments, take pH measurements of the three samples, and predict which...
Curated OER
DNA Coloring - Transcription and Translation
In this DNA worksheet, pupils review the transcription and translation processes. Students label and color the different parts of a DNA strand. This worksheet has 7 fill in the blank questions.
Curated OER
Volumetric Analysis / Titration
Titration, and the lab skills that are needed to support it, is detailed here, with the reasoning behind standard solutions, concentration and volumetric analysis covered. Your young lab assistants will learn the skills of determining...
Curated OER
DNA and RNA Structure and Transcription
Young scholars compare and contrast the structure of RNA and DNA.They summarize the process of transcription and translation. The lesson uses an inquiry model and the use of codes in DNA.
Curated OER
Protein Biochemistry: Evidence for Charged Amino Acids in Proteins
Young scholars add the acid and base drop wise as the protein precipitates. If either are added too rapidly, students may miss detail or the protein may not have sufficient time to renature. Casein does not buffer the solution well when...
Curated OER
What is pH?
Young scholars describe pH and the importance of it in the natural world. In this Biology lesson students compare the pH of different mixtures.
Curated OER
Acids and Bases
In this acids and bases worksheet, students will identify the molecules represented in a diagram equation and determine if an acidic or basic solution has been produced. Students will list the properties of acidic and basic solutions....
Curated OER
Acids and Bases
In this acids and bases worksheet, students summarize the key properties of acids and bases and define pH. Students have 18 problems to solve.
Curated OER
Writing Acid and Base Equilibrium Constants
For this acid and base worksheet, students calculate the equilibrium constant for weak acids and weak bases. This worksheet has 10 problems to solve.
Curated OER
Digestion Experiment
In this digestion experiment worksheet, students follow the procedures to set up an experiment about stomach digestion using pH paper to test for acidity.
Curated OER
Indicators
In this indicators instructional activity, students write equilibrium equations, determine the pH at the transition point of the indicator, and calculate the value of pKa. This instructional activity has 7 problems to solve.
Curated OER
Determination of the percentage of Acetic Acid in Vinegar
Students determine the concentration of acetic acid when the concentration of the base with which is titrated is known. They investigate how to weigh a sample using the balance, measure volumes using graduated cylinder, explore the...
Curated OER
Anaerobic Lactic Acid System Exploration
Students explore the role, functions, and conditions in which lactic acid is produced. They share ideas to complete a KWL on the vocabulary for the activity then research these ideas futher on the internet using a set of prompting...
Biology Junction
Protein Synthesis
Watson and Crick built the first model of DNA in the 1950s, and our understanding of DNA since then continues to grow exponentially. Scholars learn about protein synthesis by observing a presentation and completing a worksheet. Both walk...
