Middle schoolers investigate the strength of acids and bases experimentally. They answer the question, "How can pH be used to determine possible product tampering?" by testing acids and bases with litmus paper.

Third graders find the area of rectilinear shapes by partitioning them into two non-overlapping rectangles and adding the areas of the non-overlapping parts together. It allows learners to recognize area as an additive.

Third graders measure area by counting unit squares inside a rectangle.

Demonstrate to your middle school science learners how chalk breaks down in a weak acid. Discuss what affects acidic rain might have on ecosystems. Lab groups then choose one of two questions: "How does acid precipitation affect an...

Young scholars find the density of diet soda and regular soda. In this density lesson plan, students measure the mass of a graduated cylinder with 10 different volumes of each soda. They find the mass of the liquid alone and use the...

A more challenging set of worksheets, third graders are required to measure area by counting whole and partial unit squares. Students will realize that two partial blocks make up one whole block. Each shaded figure is on a square unit grid.

A fabulous lesson which combines mathematics with space science. Middle schoolers work in cooperative groups in order to research early astronauts and their accomplishments. They look at a variety of rocket and space shuttle designs, and...

Third graders simply count the square units that make up each figure in order to find the area. Remind the class to count carefully in order to find the correct answer.

See the underwater world through a different pair of eyes! Middle school marine biologists identify deep-sea organisms by examining images taken by an ROV from the Okeanos Explorer. After determining what creatures lie beneath the...

How do we prepare kids, especially those with disabilities, for life after school, for the workplace, for independent living? This 96-page packet is loaded with self-assessment surveys, with skill builders, with information about rules,...

Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...

Just because we have the ability to determine an organism's traits through genetic testing, should we do it? Middle-school medical experts examine the ethical dilemmas in biotechnology in the 18th and final installment in a series of...

Sometimes the hardest part of planning any unit of instruction is determining the activities that reinforce the concepts of the lessons and support the development of student skills. This first resource in the Health Smart series...

Students explore DNA restriction mapping. They cut pieces of paper into lengths representing those produced when specific enzymes are used to cut a strand of DNA.

In this determinants worksheet, 9th graders solve 10 different problems that include different matrices. They calculate the determinant of each matrix using the data given for each. Then, students define the 2 X 2 matrix and its...

Students analyze cantilever stress using COSMOSXpress. In this engineering lesson plan, students calculate the beam's maximum deflection. They investigate the effect changing beam dimensions.

In this map skills worksheet, students analyze a city map and study the compass rose. Students answer 10 questions about the map. This is an online interactive worksheet.

Seventh graders use their knowledge of multiplication and problem solving to determine the total weight of multiple objects. In this multiplication instructional activity, 7th graders weigh various manipulatives, record the weight, and...

In this DNA worksheet, students examine a sequence of DNA of a fictitious species. They determine the traits the species has given amino acids sequences and chart of traits that each amino acid sequence indicates. Students transcribe and...

Sometimes all you need is a good heading to determine the main idea in a block of text. Young readers learn how to use headings to guild them to determining the main idea. They practice as a class, in pairs, and then on their own. The...

In this dialogue worksheet, students determine what words are missing from the conversation between Ellie and Alice. This exercise tests English language learners' contextual language skills.

What does that word mean? I can sound it out, but it just doesn't make sense. Teach your class a sure fire strategy to combat those pesky unknown words. You'll introduce the concept of context clues through metacognitive modeling,...

Pairs use an online simulation to determine the epicenter and magnitude of an earthquake. Using real data about the earthquake's maximum S wave amplitudes, they then determine the magnitude. The resource provides a great career...

Explore optics using an inquiry-based experimental approach! Young scholars use a set of materials to design and build a unit capable of focusing a beam of light. They experiment with different lenses to determine the best approach to...
