The purpose of this experiment is to show students that pulleys are made of at least two wheels with groves for holding a rope or cable. By using the pulley that they have constructed, students will see first-hand how a pulley makes work easier by lessening the force needed to lift or move a load. Finally, as a review of previous lessons on simple machines, students will be able to match examples of all the simple machines to their correct category.

In this lesson, students will use their energy to understand inertia. Students will run a distance of 10m and attempt to stop exactly on the finish line. They will then discuss why it was difficult to stop their motion.

In this lesson, students identify three shapes: circle, square, and triangle. They will bend a pipe cleaner into a shape of their choice and group it with similarly shaped pipe cleaners their classmates have made. They will also be able to identify the colors of their pipe cleaner and group them with similarly colored pipe cleaners.

In this lesson, students extend their use of dilation to explore similar triangles. Students will be led through an activity using Geometer's Sketchpad, and using their prerequisite knowledge of dilated figures to explore "similar triangles", as will as properties of similar triangles
In this lesson, students will explore how sound travels through the air …
In this lesson, students will explore how sound travels through the air and how sound interacts with the eardrum. Students will stretch plastic wrap across a bowl, place rice grains on top, and make observations when a noise is made close to the bowls. Students can experiment with different sizes of bowls and varying volumes of the noises.
In this lesson, students will investigate the basic concepts of speed and …
In this lesson, students will investigate the basic concepts of speed and distance. They will time how long it takes them to move at varying speeds through several distance measures.
In this lesson, students construct their own sundial and use it to …
In this lesson, students construct their own sundial and use it to investigate how a shadow is formed. They can also predict changes in shadow length and direction in relation to light source and motion.
This lesson helps students better understand why and how the moon shines …
This lesson helps students better understand why and how the moon shines at night, why it is dark at nighttime, and that it is always day somewhere on Earth.
In this lesson, students will learn about the layers of the Earth …
In this lesson, students will learn about the layers of the Earth and where lithospheric plates are located and how plate movement can affect the Earth's surface. They will also create models of the different types of volcanoes.
In this lesson, students will explore erosion by investigating the impact runoff …
In this lesson, students will explore erosion by investigating the impact runoff has under three different scenarios with varying amounts and types of vegetation.
