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.

Students identify substances that are acids and alkalis. For this acids and alkalis lesson, students conduct tests to determine if given substances are acids or alkalis. They test substances and explain the different qualities that make...

Students investigate pH levels in bodies of water and experiment with acid/base reactions. In this water and pH lesson plan, students observe changes in pH levels of a sample solution and observe a Bronsted-Lowry reaction. Students...

Students investigate the physical, chemical and biological parameters necessary to establish an ecological baseline. Establishing an ecological baseline not only shows the ecological characteristics of a creek but makes the possible...

Students celebrate the culture of Greece. In this multicultural lesson, students participate in several activities which examine the culture of Greece. Students study the Greek alphabet, identify the country on a world map, and make...

In this health worksheet, students examine the human body and make mental connections to the target function highlighted in the sheet.

In this science worksheet, students answer 10 true or false questions about kinds of materials and their characteristics. They complete a chart by naming 4 different materials, naming an object made from that material, and indicate one...

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for...

Eleventh graders use titration methods to study properties of antacids. They look at the strength, effectiveness, PH, and effect of supplements taken at the same time. They make observations after the different mixtures are combined and...

Learners explore how hydrothermal vents are formed and where they are located on the ocean floor. They study how scientists use CTDs to locate hydrothermal vents.

Students study acid and bases and how they fall on the pH scale. In this solutions lesson students complete a lob activity using litmus then fill out a data table.

Pupils explain the importance of water in our daily lives. In this aquatic science activity, students identify different ways to purify water and make it potable. They design and construct a water filter based on researched information.

Students identify acids and bases. In this chemistry lesson, students use red cabbage juice as an indicator of whether the liquid is an acid or base. Students discuss the results.

Fourth graders study how environmental engineers monitor water quality. They use environmental indicators to determine the quality of stream water in their area. They count the number of macroinverabrates and use the information they...

Sixth graders describe the physical and chemical properties of acids. In this chemistry instructional activity, 6th graders test the acidity of different solutions. They identify acids and bases using the pH scale.

High schoolers investigate the mixtures of solutions. They utilize cups filled with bases and acids. Students test and determine the pH of each cup. The multiple cups are compared to each other in order to chart acids and bases according...

Students examine water quality indicators,test water quality and record their results.  For this water quality lesson students complete a water testing lab and complete a lab report. 

Fifth graders investigate evidence for changes in matter that occur during a chemical reaction.

Students 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 washing...

Students participate in a simulation of how diseases are transmitted. Each student holds a test tube, with only one containing the "disease" while the others have water. They move around the room until told to stop. Using droppers to...

Working with children and adults who have severe communication disorders presents its own set of challenges. The goal of this resource is to provide educators, parents, and guardians with research-based suggestions for how to meet these...
