Students observe the sounds of different brass instruments in order to understand how to create different pitches. In this musical instructional activity, students create a "brass" instrument from everyday household objects. The students...

Cell membranes and the factors that affect its integrity are studied, with Beet tissue used as the model. A poster to display findings of the permeability of the membranes would clarify understanding and also allow a layer of language...

A change is coming. Pupils use unit cubes to investigate how changes in the length, width, and/or height affects volume and surface area. They extend the results to write and test predictions on the effect of changing multiple sides on...

Learners determine the normal behavior of California blackworms. They determine how various concentrations of assigned toxicants affect the worm's behavior. Students are introduced to testing of potential toxicants, an important...

As a way to combine life and physical science, or simply as an investigation of plant transpiration, this lesson is sure to inspire! Middle schoolers capture the moisture given off by plants that are placed in different conditions. They...

The risk of contracting an infection in the hospital is low, but it does happen. Learn what risk factors have the highest correlation with hospital-acquired infections in the final lesson of a three-part series. Using the open source R...

Eleventh graders test the pH and alkalinity of Pago River. In this ecology lesson, 11th graders collect data and use spreadsheet to graph results. They analyze and share their findings with the class.

While pupils design their own lab experiments, they will not form a new species. Scholars take their materials and design an experiment regarding reaction rates. 

What happens to a volume when you scale the dimensions of a rectangular prism? In this problem, a box of clay is increased in each dimension, with the intent to see if learners can generalize the result. The addition of...

Students explore air pollution. In this ecology and air pollution lesson, students perform an experiment in which a Vaseline coated lid is placed inside and outside the classroom. Students make predictions and then record what they see...

Young scholars explore the properties of enzymes. In this chemical reaction lesson, students explore enzymes through a Web-quest and investigative study. Young scholars will collect and summarize data and create a class presentation....

Challenge algebra learners to use the difference of cubes to solve this problem. Once your charges have taken out the factor (a - b), combined the like terms and set them equal to zero, the problem becomes a factorable quadratic...

Students describe the characteristics of anthrax infections, distinguish between the three anthrax forms and analyze the effectiveness of anthrax vaccinations. They relate anthrax to bioterrorism.

Provide guidance and practice of the useful skill: solving rational equations using both an algebraic and graphical approach. Pupils solve increasingly more difficult rational equations using algebraic methods. After, they...

Here is a multiple choice question that would make a good assessment question. Algebra students are to look at the structure of the formula for a given radius of a cylinder and find the resulting radius when the height of the...

Students identify the forces that affect the weight of an object. In groups, they determine the proper math model which can demonstrate the attraction between two objects based on gravity. They discuss the relationship between the weight...

Students investigate threee types of maps. In this algebra lesson, students idenitfy different maps and explore how they relate to the area keeping cllimate and topography in mind. They discuss maps used to navigate land. air and sea.

Students will explain the Archimedes's Principle. In this lesson on plankton, students will describe three factors that can affect the buoyancy of plankton. This lesson contains extensive background information, extensions, and multiple...

Students are able to design and conduct an experiment related to electrical generation. They are able to list the factors that affect the amount of current that can be generated by a simple generator, such as the number of turns of...

Students analyze the causes of cancer from a genetic standpoint. They explain the increase in cancer with age and create a hypothesis for cancer development. They use the laws of probability as well.
