Double Pendulum
What's better than a pendulum for studying motion and periods? A double pendulum! Young physical scientists use an interactive to explore pendulum motion—times two. The resource boasts a host of parameters to change and a running graph...
Curated OER
Reflection and Mirrors
In this reflection worksheet, students will review the law of reflection and label a diagram with its angle of incidence and angle of reflection. Then students will compare different mirror surfaces as convex or concave. This worksheet...

Trajectory - Angle Launched Projectiles
Horizontal and vertical speeds change as projectiles move through space. As part of a series on vectors and projectiles, scholars create vector diagrams to compare these speeds at various locations. They they determine the values for...
Curated OER
Simple Angles
Third graders identify and construct right, acute and obtuse angles and begin to appreciate the degree and unit of measurement of angle. They know the degree value of angles that are simple fractions of a whole turn know that the angle...
Curated OER
Measuring Body Angles
Students use technology to graph and compare angles. In this geometry lesson, students range of motion in the environment. They identify the missing parts of polygons using similarity and congruence.
PhET
Molecule Shapes
The shape of a molecule is determined by the arrangement of atoms around the central atom and lone pairs of electrons. Scholars build models of molecules using single, double, and triple bonds. They can then see real molecules bond...

Three of a Kind
One is chance, two is a coincidence, three's a pattern. Scholars must determine similarities and differences of a regular hexagon undergoing dilation. They look at lengths, angles, areas, and symmetry.
Willow Tree
Ratios and Proportions with Congruent and Similar Polygons
Investigate how similar and congruent figures compare. Learners understand congruent figures have congruent sides and angles, but similar figures only have congruent angles — their sides are proportional. After learning the...

Christmas Tree Angles
In this angles worksheet, students measure angles to make triangles and cut them out to make a Christmas tree. Students draw and cut 5 triangles to make their tree.
Curated OER
Working With Angles
In this math worksheet, students collaborate with a "study buddy" or "coach" to learn whether an angle is acute, obtuse or right. Students follow the directions to go through the process of deciding what classification an angle has....
Curated OER
Introducing Angles
Sixth graders identify, compare and interpret the characteristics of polygons and angles in order to meet spatial sense, geometry and measurement standards. They also sort shapes into three categories, polygons (regular and irregular)...

Leveled Problem Solving Special Pairs of Angles
In this special pairs of angles practice worksheet, students sharpen their problem solving skills as they solve 6 story problems.
Curated OER
The Sum of All Angles
Young scholars add up the different angles using the angle addition postulate. In this geometry lesson, students differentiate between interior and exterior angles. They calculate the different angles for triangles and use proof to show...
Curated OER
Angle Insolation
In this science worksheet, young scholars look for the answers that are related to the concept of insolation and measuring different angles.
Curated OER
Right Angles
In this math worksheet, students compare different shapes while identifying the right angles. They also write down the right angles seen in a classroom.
