A Study in Paper Permanence
Twelfth graders compare the permanence of papers by testing pH, determining presence of alkaline reserve as well as fold endurance, and testing lignin content.
They indicate the strength by using a starch test as a comparison.

Sin x = x/100
For this trigonometry worksheet students determine the number of solutions for the problem sin x = x/100. The one page worksheet contains one problem with solution.
Curated OER
Acid and Base Testing
Students study descriptions of indicators and the way they are used to identify acids and bases. They use this information to determine if unknown solutions are acids or bases.
Curated OER
What's A Problem?
Fifth graders utilize strategies to solve a variety of problems and create problems of their own. They write explanations of problem solutions and using a checklist, evaluate themselves.
Curated OER
Acids and Bases - Vinegar II
Eighth graders experiment what happens when acids and bases are mixed together. In this acids and bases experimental activity, 8th graders decide which of three solutions of unknown pH will neutralize a fourth solution of unknown pH.
Curated OER
Science: What Happens to Create the Lode?
Students understand how mineral deposits are formed and why they are not evenly dispersed. They create and describe three different precipitates from four solutions simulating mineral ore deposit formation in sedimentary rock.

Predicting Nations at Risk
Students explain the "So what?"-or the international implications-of factors that indicate the developmental status of a nation.
Curated OER
Florida's Springs
Students follow the journey that water takes in aquifers and springs. They write about the major threats to the aquifer and the solutions to these threats.

pH of Household Products
Tenth graders are provided with a piece of paper such as index, art, construction, or computer coating it with a universal indicator. They use cotton swabs HCl and NaOH to draw a picture repeating the same process using lemon juice and...
Curated OER
Coral Reef Bleaching
High schoolers explore the structural biology of corals. Working individually, students identify how corals become bleached and which conditions produce more and less coral bleaching. High schoolers explore how this effects the...
