Students find the factor of proportionality in similar polygons. In this similarity of polygons lesson plan, students measure the sides and angles of polygons and derive a factor of proportionality between corresponding pairs of sides...

Tenth graders investigate the theorems of ASA, AAS, AAA and ASA. For this geometry lesson, 10th graders discuss the theorems of triangles and how it is used to solve for missing sides or angles. They review how two angles are formed by...

Learners investigate an accident and relate it to math. In this trigonometry lesson, students measure the accident scene, the friction produced, and the speed from the skid marks. They create a poster of their findings.

Students become familiar with the causes for formation of shadows. They create shadows, compare the size and shape of the shadow with the actual object, engage in shadow play theatre, and discover what happens to shadows when there is...

Students make a circle graph. In this graphing instructional activity, the teacher conducts a class survey, then demonstrates how to make a pie graph. When students are comfortable with the material, they use a worksheet to create their...

Pupils investigate conservation laws using a potato launcher. In this physics lesson, students measure angles, time and distance of the potato. They discuss applications of experiments like this.

In this exploring pendulums worksheet, students experiment with pendulums they make in the lab. They vary the length of the strings and the weights to observe the changes in the pendulum's amplitude and frequency. They answer 3 analysis...

Students participate in finding the slope of a sand pile and then other materials. In this geology lesson, students describe what happens to the piles of materials when they are poured through a funnel. Students measure the slope using a...

In this triangulation worksheet, students solve and complete 11 steps of an experiment to determine the distance to a far away object using triangulation and trigonometry. First, they select a far away object and create a baseline far...

Students conduct an experiment.  In this landslides lesson, students learn about landslides and discuss how they could minimize the risk of landslides.  Students complete an experiment to see if changing the slope of the land...

A six-page packet walks, or bends learners through angles that combine to create triangles. Definitions are given for right triangles, obtuse and acute triangles. They draw angles according to directions, using a protractor to meet the...

In this solar storms worksheet, students use a diagram given the location of two STEREO spacecraft satellites, a coronal mass ejection, the sun and the Earth to solve 2 problems about the coronal mass ejection. Students use segments,...

Learners participate in an experiment to discover the properties of lift. They work together to complete calculations and collect data. They share their results with the class.

In this geometry worksheet, students answer questions about midpoints, distance, lines and segments. They are given different shapes and asked to calculate the angles, and sides of polygons.

Students observe, measure and sort leaves.  In this leaf lesson students divide into groups and observe the different kinds of leaves. 

Young scholars use protractors, strings, and straws to construct a device used to determine the height of tall objects. In this applied geometry lesson, students use common objects to construct a tangent height guide. They use principles...

Seventh graders investigate with light rays. In this light lesson, 7th graders determine the angle of reflection using simple materials. They continue the investigation by exploring the theory that light which is not reflected or...

Students discover soil and Earth movement by experimenting in class.  In this Earth Science lesson, students utilize a stream table, soil, graduated cylinder and water to create a re-enactment of a landslide.  Students simulate...

Students explore the concept of similarity and congruence. In this similarity and congruence instructional activity, students cut out strips of paper and form a triangle. Students try to prove that their triangles are congruent using the...
