Pupils explore the midsegment of a triangle in the geometry instructional activity. They draw and measure the segment joining the midpoints of the two sides of a triangle and compare its length to the length of the third side of the...

Here is one of the better lessons I've come across on how to teach fractions and decimals. This lesson does a great job of showing how these two mathematical representations of numbers are interrelated. Some excellent websites, printable...

Instructions for series of six activites, a reading of scientific literature, and a choice of six assessments await you in this physics resource. Well-written plans guide you in guiding your pupils to experiment with levers, pulleys,...

Students examine data to investigate the impact of lead shot pellets on waterfowl populations. They graph their findings and discover how lead in ingested by birds and poisons them. As an extension, students research legislation and...

Students investigate the question, "how does understanding the properties and characteristics of light help us to enhance our quality of life?". They apply knowledge gained though the unit in order to create an optical device.

Students investigate space travel. In this space travel lesson students examine space exploration history, engineers and scientists involved in space exploration, and Newton's third law of motion. Students make rockets.

Color is the focus of this amazing resource packed with math, social studies, science, and language arts activities. Kids create a color word wall and post symbols, graph the number of objects they find of each color while on a...

High schoolers explore the concept of right triangles as they construct a right triangle using Cabri Jr. Learners find the midpoint of the hypotenuse and construct a line from the midpoint to the vertex of the right angle. They then...

Scholars investigate how the tempo of music affects heartbeats. Groups  develop hypotheses about music and its connection to heartbeats before carrying out an experiment. They analyze and present data from their investigations.

This heady calculus text covers the subjects of differential and integral calculus with rigorous detail, culminating in a chapter of physics and engineering applications. A particular emphasis on classic proof meshes with modern graphs,...

Take a another look at ellipses. The seventh segment in a series of 23 in a Precalculus module continues to investigate the graph and equation of an ellipse from the previous lesson. Scholars investigate the fact that the sum of...

Right angles, acute angles, obtuse angles, central angles, inscribed angles: how many types of angles are there? Learners first investigate definitions of inscribed angles, central angles, and intercepted arcs. The majority of the...

How do you find the measure of an arc? Learners first review relationships between central and inscribed angles. They then investigate the relationship between these angles and their intercepted arcs to extend the Inscribed Angle Theorem...

Discover the scale factor by finding the constant of proportionality. Pupils investigate drawings to determine whether the distances are proportional. The activity defines the scale factor as the constant of proportionality, or unit...

Investigate complex problem situations by applying inequalities. Building from concepts explored in the previous lesson plan, learners read word problems and develop inequalities to represent the situation. They then solve the...

Escape to investigate hyperbolas. Pupils take a look at what happens to the elliptical orbital path of a satellite that exceeds escape velocity as the opener to the eighth lesson in a unit of 23. Scholars analyze basic hyperbolas and how...

Move all rational functions—well, maybe. Learners investigate the graphs of the reciprocals of power functions to determine a pattern between the graph and the power. Pupils graph rational functions where transformations are clearly...

Combine functions for the first time. Pupils investigate composition of functions using a function table and then function machines in the 17th installment in a 23-part Precalculus series. Scholars learn the two notations for composition...

Second graders study Earth's materials. In this air and weather lesson, 2nd graders note changes in the weather and examine tools that help us study the weather. Students analyze how changes in the environment make changes in the...

Students use logical arguments and inductive reasoning to make or disprove conjectures. After observing a teacher led demonstration, students discover that the deductive process narrows facts to a few possible conclusions. In groups,...

This turn-key unit on ratios and unit rates walks through a 30-lesson unit on teaching proportional reasoning, with each lesson broken into detailed teaching notes and time allotments for all parts. An unbelievable resource when taken...

Students participate in an activity in which they investigate the scientific method and seed germination as well as practice graphing and metric measuring skills. Students examine toxicity by exposing Wisconsin Fast Plants seeds to toxic...

Young scholars investigate that chemicals may affect different people in different ways. They also realize that their perceptions of dangerous materials may not be realistic and that the news media may not provide all the information...

Investigate the growth rates of alien animals. Pupils study fictional animals from another planet to determine how much they grow per year. The investigators plot the growth of their animals over a period of time and then compare...
