New! Kelper's Three Laws
A flipped classroom lesson introduces astrophysics fanatics to Kepler's three laws of planetary motion. After reading about the laws of ellipses, equal areas, and harmonies, and also learning how Newton's gravitation concepts come into play, they answer nine questions as a review. When students return to class after exploring this assignment, review the answers to the questions and then provide some problem solving practice.
Challenge your students to come up with their own explanation of why this interesting mathematical law works! Sal, accompanied by Vi Hart, demonstrates BenfordÕs Law. They challenge the listeners to see if they can give an intuitive reason for why this law fairly accurately models certain number patterns. There is a follow-up video with an explanation.
How does the Law of Sines differ from the Law of Cosines? Learners, working cooperatively in small groups, try to gain insight into this question. The activities center around using both laws in different scenarios including real-world examples.
New! Sources of Law
From where do United States citizens derive their laws? This resource offers an overview of the various sources of law, such as the Constitution, statutes passed by Congress, and judicial precedents established through court cases. It also reviews special systems of law, such as military and juvenile law.
From the Magna Carta. Code of Hammurabi, and common law to today's special interest groups and law enforcement agencies, test your young historians on the evolution of the rule of law in society with this multiple choice assessment.
Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different pressures. In the end, both Charles' and Boyle's laws are explored.
New! Inverse Square Law
The inverse square law is revealed when your class participates in this activity. They move a graph paper or perfboard square back and forth in a square of light to see how the intensity changes. You will definitely want to add this illuminating activity to your collection of physics demonstrations.
Although it was published in the year 2000, this chemistry assignment is ideal for practicing the application of Charles' law. There are seven real-world problems to solve, and plenty of space provided for doing so. Add this to your library of homework pages for when your chemistry class is studying the relationship between volume and temperature.
Explaining "one of the most intuitive laws in mathematics and in probability theory," Sal begins a discussion on the law of large numbers. He clarifies that it is often misused due to its broad application. Students will appreciate his clear-cut instruction about this law, and how he applies it to the concepts he has already covered.
The Law of Thermodynamics states, "Energy can never be created or destroyed, it can only be transformed from one form to another." Sal does a fabulous job of illustrating this crucial law to students through the use of excellent drawings and examples. By the end of the video, he has proven that energy must be transferred into another form.
Sal derives the Law of Cosines using a method similar to the wayward ship captain word problem he solves in another video. This video provides a good review of using the SOH-CAH-TOA model, the Pythagorean Theorem, some of the basic trig identities, and algebra.
Sal introduces students to Hess's Law. The law states that the energy change of a process is independent of how we get from one state to another. He sets up a series of reactions, and solves them to illustrate the principles behind Hess's Law. This video is very heavy on the math and a calculator would be a useful tool.
In this video, Sal proves the Law of Sines by using the SOH-CAH-TOA model and setting up equivalent ratios.
The associative law of addition was confusing for my students, but it is totally necessary for understanding order of operations in later mathematics. In this video, Sal uses the associative law of addition to write the expression (77+2) +3 in a different way. He explains that you can associate or add numbers in different ways. Sal demonstrates that adding (77+2) +3 is the same as adding (2+3) +77.
Sal utilizes a problem from a chemistry textbook in order to illustrate what the enthalpy change is for the formation of methane from a solid carbon, and hydrogen gas. In order to solve the problem, Hess's Law must be utilized. Sal explains what Hess's Law is, then uses it to solve the problem in a clear fashion.
Sal explains the commutative law of addition. He adds the number 5+8+5 three different ways. Then he shows that when he adds 5+8+5 in any order the answer will be the same. Note: This video is great, but would be nicely accented with class discussion and class-worked examples.
New! Kelper's Laws Lab
Using an online planetary simulator, astrophysics students explore each of Kepler's laws. The 13-page printable handout walks them through the activity, which also includes using string, pushpins, and a pencil to model three different ellipses.
Middle schoolers examine the 1834 Poor Laws. In this law lesson plan, students discover how the poor were cared for in the 1800's. Middle schoolers gain knowledge about workhouses and the conditions there. Students view posters and discuss what they portray.
Students simulate the legislative process. In this British Parliament lesson, students discover the steps of the legislative process as they propose mock bills and attempt to make them laws.
Third graders define the term law, explain benefits gained from laws and appreciate these benefits in daily life.
