Published by OpenStax College, this introductory, algebra-based, two-semester college physics book is grounded with real-world examples, illustrations, and explanations to help students grasp key, fundamental physics concepts. College Physics includes learning objectives, concept questions, links to labs and PhET simulations, and ample practice opportunities to solve traditional physics application problems.
Students will investigate the characteristics of electromagnetism and then use what they learn to plan and conduct an experiment on electromagnets.
This is a description of a student experiment that teachers can adapt to allow students to prove that electric current produces a magnetic field. The sample includes a specific example of how to do the experiment which can be adapted to an inquiry investigation by having students complete the initial experiment and then write their investigation question and further investigate the phenomena. When completing this as a demonstration or student experiment batteries can be substituted for the variable power supply if power supplies are not available or convenient to use. The voltage provided to the circuit can be easily manipulated by changing the number of batteries connected.
In this lab activity, students use a digital temperature probe to compare the temperature changes when four different alcohols evaporate. The analysis questions provided guide students to connecting the energy changes associated with the change of state with the structure of molecules of substances. Before beginning the lab, students are asked to consider the structural formulas of the alcohols used in the lab: methanol, ethanol, 1-propanol, and 1-butanol. After collecting data for the first three alcohols, students predict the temperature change for 1-butanol and then collect data to test their prediction. The resource linked here is a sample. More complete information, including teachers guide and safety information, is available for purchase from Vernier Software and Technology using the link provided on the final page of the sample.
These two lessons work together to explore reversible and irreversible changes of state through guided investigations. The PDF is a set of activities focusing on materials followed by some optional post-activity lessons. Two of these post activity lessons deal with reversible and irreversible changes to materials. The first lesson involves teachers showing students phenomena and then asking the students to generate questions about their observations of the phenomena. The second lesson involves students engaging in investigating, explaining and asking questions about two irreversible changes and using observations to identify what about the changes make them irreversible.
The goal of this lesson is to assist students to relate the forces acting upon particular objects and the “unseen” resolution of those forces. The video begins with a story line involving Adam, who helps his father in the garden by disposing of a garbage bag of leaves—the very act that involves resolution of forces. This lesson includes embedded video clips, animations, diagrams and inquiry-based experiments where students are required to work collaboratively and answer thought-provoking questions. The experiments will involve the study of the resolution of forces on objects placed on varying planes or on platforms of different angles, using materials that are easily found. Finally, students are required to discuss and apply what they have learned to determine whether it is easier to push or to pull a luggage bag with wheels. The lesson will take about 50 minutes to complete.
This video lesson is an example of ''teaching for understanding'' in lieu of providing students with formulas for determining the height of a dropped (or projected) object at any time during its fall. The concept presented here of creating a chart to organize and analyze data collected in a simple experiment is broadly useful. During the classroom breaks in this video, students will enjoy timing objects in free fall and balls rolling down ramps as a way of learning how to carefully conduct experiments and analyze the results. The beauty of this lesson is the simplicity of using only the time it takes for an object dropped from a measured height to strike the ground. There are no math prerequisites for this lesson and no needed supplies, other than a blackboard and chalk. It can be completed in one 50-60-minute classroom period.
Part 1 of the X-ray Spectroscopy Unit from NASAs Imagine the Universe! lesson plans includes a series of three lessons on the formation of elements in stars. During this three lesson series, students learn about the life cycle of stars and model the formation of elements in stars. The lessons are a demonstration of type so fusion reactions and modeling not just the changes to matter during the processes but also the energy involved in these reactions.
This video lesson highlights how science can be learned from daily life experiences. It emphasizes the ways in which simple laws of physics can be understood from personal observations and experiences, and in fact it demonstrates that we use these laws as if they were built into our instincts. The video also introduces Newton's laws of motion. The title, Gravity at Work, comes from a fascinating example of two laborers working at a construction site in Pakistan. In this lesson, Newtonian equations of motion are used to determine the velocities and height achieved by the projectile in a very simple and basic manner.
This video lesson is part of a two-part series and introduces the concept of temperature. Temperature can be a challenging concept to convey since our perception is tied to words that are relative to our own experience, which varies quite a lot. A short activity to be performed in the classroom shows the need for a temperature scale since qualitative descriptions are not adequate. Temperatures that vary from the hottest to coldest recorded temperatures on earth are shown in advance of introducing the boiling temperatures of a number of cryogenic liquids.
The aim of this lesson is to introduce the concepts of heat and temperature, which many students find confusing. During the lesson, students will be asked to explore and discuss situations where even though the same amount of heat is absorbed by several substances, the increase in temperature of the substances is different. This video lesson presents a series of stories relating to heat and temperature, beginning with a visit to a factory where gamat oil is produced. In the video, a man dips his finger into boiling gamat oil yet feels no pain. The scene will draw students’ attention and raise their curiosity about how this is possible. Students will also carry out several experiments to compare and relate the situations where the same amount of heat absorbed by substances will result in different temperatures. By the end of this lesson, students will understand the term “specific heat capacity” and will recognize the difference between a high or low specific heat capacity. They will also understand the term “thermal diffusivity” and how this relates to the topic of the lesson. This lesson offers some authentic learning experiences where students will have the opportunity to relate the concept of heat and temperature to everyday situations. It will take about 50 minutes to complete - however, you may want to divide the lesson into two classes if the activities require more time.
In this lesson, we learn how insects can fly in the rain. The objective is to calculate the impact forces of raindrops on flying mosquitoes. Students will gain experience with using Newton's laws, gathering data from videos and graphs, and most importantly, the utility of making approximations. No calculus will be used in this lesson, but familiarity with torque and force balances is suggested. No calculators will be needed, but students should have pencil and paper to make estimations and, if possible, copies of the graphs provided with the lesson. Between lessons, students are recommended to discuss the assignments with their neighbors.

Students use the engineering design process to design and build magnetic-field detectors, and use them to find hidden magnets. Parallels are drawn to real-world NASA missions and how NASA scientists use magnetic field data from planets and moons. The website has video clips, teaching suggestions, a student handout, and a link to the pdf of the Teachers Guide for Mission: Solar System. The Inspector Detector challenge is a series of activities that form a unit in the Mission: Solar System collection. * NOTE: The Teachers Guide does not contain the lesson plan. You will need to click on the Student Handout heading of the website to download the Inspector Detector Challenge Leaders Notes.
Students will investigate the magnetic pull of a bar magnet at varying distances with the use of paper clips. Students will hypothesize, conduct the experiment, collect the data, and draw conclusions. As a class, students will then compare each teams data and their interpretation of the results.
This is a lab procedure during which the student investigates the strength of a magnetic field within a coil of wire using a magnetic field probe. Students will investigate how the magnetic field strength depends on the current in the wire as well as the number of coils in the wire.
This lesson presents the basics of aerodynamics by using kite flying as an example, i.e., forces acting on a flying object. Students will measure the net force acting on a kite due to blowing air and will learn how a simple instrument like a spring can be used to measure such force. They will also examine and experience how the force on the kite is transferred to the string in the form of tension and will again measure that tension with a simple spring. This lesson will take about 30 minutes to complete. One will need a calibrated spring to measure forces, as well as a few springs to study the coplanar forces.
