Equality does not equal equity. That's the take-away from a lesson that asks young people to consider what could be done to make a variety of situations more just, more equitable. After examining images that illustrate the difference...

Kepler's second law of planetary motion, specifically, the law of equal areas, is demonstrated by your high schoolers. On the provided graph paper, they mark out the designated path of Earth at two different times of the year and then...

In this measurement worksheet, students use the ladder method to convert basic units. Then they compare each using greater than, less than, or equal to. Students also write the correct abbreviation for each metric unit.

It's the law—every action requires a reaction, no matter how small. Pupils experience two demonstrations of Newton's third law of motion as it relates to thrust in the 10th segment of a 22-part unit on flight. Using their mathematical...

Apply robotics to connect physical properties to chemical properties. Future engineers use robots to determine the melting points of various fats and oils. The robots can do this by measuring the translucency of the fats as they heat up.

Photosynthesis requires energy and produces food, and cellular respiration produces energy and requires food. An interesting lesson analyzes the factors that affect the rates of photosynthesis and respiration. Classes spend one day...

Second graders, in groups, develop models to show how forces such as gravity, friction, equal, unequal forces and change in direction work on marbles.

Learners examine their own strengths and weaknesses and try to determine if it is a result of nature, nuture or both. After reading an article, they discuss how gender may or may not account for differences in intelligence. They...

Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...

Create models of the infrared, visible, and ultraviolet portions of the electromagnetic spectrum. Working in small groups, your class can investigate metric conversions calculations. They will find the length of the waves in nanometers,...

Three memorable activities build on each other to give physics masters a firm grasp of Newton's Second Law. Pupils play with a lab cart on a flat surface and on an incline to confirm that force is equal to mass times acceleration. In the...

Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

Students investigate the coefficients in a chemical equation and their relation to moles. In this moles and coefficients lesson plan, students perform a single replacement reaction of copper (II) sulfate and zinc and find the ratio of...

Force equals mass times acceleration. Physics whizzes apply this formula to six different diagrams, solving eight acceleration problems in all. This is a practical assignment, perfect for homework when practicing Newton's second law of...

Sometimes it is difficult to grasp topographic maps. Here is a clever presentation designed to help your middle school earth scientists understand. Beginning with a side view of a pair of mountains, a graphic guy walks up one slope. As...

Dare your class to drive dissolved carbon dioxide out of carbonated liquid at different temperatures to discover if there is a difference in rate. To make this experiment more sound, have explorers use equally measured amounts of soda...

Can you disprove the law of conservation of mass? Pupils observe the teacher weigh each part of a reaction. Then, the teacher weighs the result of the reaction and everyone sees that the products do not equal the reactants. Then they...

Learners estimate and determine the number of cents (pennies) that are needed to equal the mass of a variety of common objects. They develop a process for measuring and explore concepts related to units of measurement.

In this chemical equations worksheet, students learn to balance chemical equations by counting the number of atoms of each element in the products and reactants and making them equal. This worksheet has 5 problems to solve.

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...

The Milky Way gets great reviews on Trip Advisor — 100 million stars. The activity allows scholars to rethink their assumptions and prior knowledge. Pupils observe a set of two lights at equal distance and brightness, but they believe...

High schoolers discuss that the conservatin of energy states that the energy imput must equal the energy output. They then figure out how can a machine help you to perform task otherwise considered impossible? Students discuss the six...

In this Kepler's Laws instructional activity, students answer questions about Kepler's three specific laws. They identify what the Elliptical Orbit Law, the Equal Area Law and the Harmonic Law mean.

In this equilibrium learning exercise, students read about the factors that effect equilibrium in solutions such as the pressure of the solution, the temperature and the concentration of the solution. They answer three multi-part...
