Welcome to our page where you can download our science lesson plans for Classical Conversations and more!

Cycle 3 Fall Lessons will be posted in Early June

As usual, lesson plans will be $3 each or come in a Fall bundle for $30. And of course we'll have a free lesson to try plus our Materials List for the fall and spring activities.

 We'll update this page shortly with the Materials List!

FREE! Cycle 2 Materials List (follows Cornerstone's Lesson Plans)

A list of everything a class will need when using our lesson plans to conduct the experiments proscribed in the 5th edition Foundations Curriculum for Classical Conversations.

FREE!  Cycle 2 Week 13 lesson: Spoon bells & "singing" wineglass

Sound is energy waves that we can hear, and even feel!

In this pair of experiments, you’ll learn about sound frequency and amplitude, and how sound can travel as vibrations through both solids and gasses.

 Cycle 2 Week 14 lesson: Cool conductors & tense pepper

In the first of two experiments, students will learn about conduction, one of three types of energy transfer. In the second, they will learn about water’s surface tension, and how it can be disrupted.

 Cycle 2 Week 15 lesson: Carol of the bottles

In this experiment, students use glass bottles and water to create their own set of musical instruments, and then perform a song! Along the way, students will get reinforcement on the topics of vibration and frequency, and the reasons why the bottles make different sounds.

 Cycle 2 Week 16 lesson: Rollin' around & free falling

In this pair of experiments, students will learn about the diameter of a circular object affects its acceleration, and how surface area and shape affect how fast an object falls through the air.

 Cycle 2 Week 17 lesson: Energy conservation & holding steady

In this pair of experiments, students will learn about how energy is converted from potential energy to kinetic energy, and how inertia works against forces to resist changes to motion.

 Cycle 2 Week 18 lesson: Somethin' screwy & inclined planes

In this pair of experiments, students will learn about how screws work, along with their history and many, many uses. Then they’ll discover how an inclined plane relates to a screw.

Using paper airplanes, students will learn about the four forces most important to flight—lift, thrust, drag, and gravity. Different paper airplane designs address these forces in different ways, making airplanes that are fast or slow, fly long or short distances, and fly straight or in circles. Four step-by-step paper airplane templates are included in this lesson.

See our step-by-step video for these designs at:

Cycle 2 Week 20 lesson: Straw Bridge Construction

Using straws, rubber bands, and modeling clay, students attempt to design and construct a truss bridge of a given length that can hold a target weight.

Cycle 2 Week 21 lesson: Medieval Warfare Part 1--Tower Construction

Have fun storming the castle! During the Medieval Period the use of siege towers reached their peak. In this activity you’ll work on building a tower out of drinking straws to reach over the top of the enemy’s walls and bring victory to your army!

Cycle 2 Week 22 lesson:Medieval Warfare Part 2--Catapults

Once more unto the breach, dear friend, once more! This week’s activity involves the history and forces used in catapults, then making two different catapults that can throw mini-poms.

Cycle 2 Week 23 lesson: Egg-Protecting Devices

Using craft stick, rubber bands, and tissue paper, pairs of students will build and test protective device that will keep an egg from breaking when dropped from a given height.
