Technology of the Deep: Experiments with Buoyant Forces

Students demonstrate the scientific method by conducting an ice cube melting experiment. They make predictions and observations, and conclude what factors make ice melt more slowly or quickly than normal.

When making sweet tea, why do people dissolve the sugar in hot tea instead of cold tea? The class discusses the previous lab and builds upon it. Working in groups, they design an experiment to determine how temperature affects the...

Test your class' understanding of free falling objects with a video demonstration that shows two equal weights dropped simultaneously. One hits the ground first, which is contrary to what students understand about the acceleration due to...

Students consider the first part of Newton's First Law of Motion, the Law of Inertia of objects at rest, which states that every object remains at rest unless acted on by a force. They perform hands-on experiments which demonstrate this...

Looking for a quick way to supercharge your electricity and magnetism unit? Assign a very responsive interactive designed to illustrate the relationship between charge, electric field, and the resulting forces. Learners experiment with...

Is there more to evaporation than just less liquid? Show young scientists the energy transformation that occurs during a phase change through a series of simple experiments. Lab partners place drops of water, ethanol, and ethoxyethane on...

Do not let friction drag you down! The 11th segment in a series of 22 focuses on the fourth force acting upon an airplane—drag. Pupils learn about the effects and causes of drag.

Does size or mass impact gravitational pull? Scholars experiment with force pairs to answer that question. They can change the size, mass, and distance between the objects using an engaging simulatoin. This allows pupils to visualize the...

Middle school chemists visit interactive websites in order to discover what happens to molecular motion when heat is added to matter. They conduct an experiment that demonstrates the expansion of matter with the addition of heat. A lab...

Students view a video and complete experiments with force and motion.  In this force and motion lesson plan, students examine small pieces and how they affect the motion of a toy car.  Students also experiment with sand paper,...
