What happens to the momentum of an object when it strikes another object? Scholars roll a marble down a ramp so it collides with another marble. By measuring the speed of each marble before and after the collision, pupils answer this...

Audio speakers, hard drives, credit cards, and even the earth use magnetic fields. While we observe the effect of magnetic fields, we can't actually see them. A viewer helps participants explore magnetic fields, some of the items that...

We all know someone who won't eat the banana with a brown spot, the grape with a dimple, and the apple with a bruise. Scholars use different fruits to explore what happens when fruits really start to decompose. They set up an experiment...

Here is a lesson which may be best suited for a library science teacher, or one that can be done by a regular teacher when in the library. In it, learners explore the best ways to use print and electronic resources to find information...

It is all in a matter of time. The model curriculum module uses parametric equations and vectors to solve problems dealing with particle motion along a curve. At the beginning of the lesson, the unit reviews parametric equations and...

There might not be a butcher or baker, but you'll have a class full of candlestick makers after a hands-on lesson about candles make from beeswax. After a brief history of where beeswax comes from, young artisans craft their own...

Students experiment with sense of smell, and how it relates to sense of taste.

Students use topographic maps to identify parts of rivers. In addition, they discover gradient and predict changes in the channels caused by variations in water flow. Other activities include sketching a river model with a new channel...

Fourth graders calculate density, compare densities of solids and liquids, measure liquids using a balance, and investigate the significance of density. They conduct an experiment to determine an order of densities, and complete a...

Students design and create packaging material for food. In this snack attack lesson, students design a package to protect a food item from heat and water. Students consider costs of materials, design, and test the package to see if it is...

Students study mechanical engineering and how it plays a part in the creation of windmills. They design and test their own windmills using various materials and sail designs.

Students compare various brands of floor polishes and test their durability and appearance.  In this floor polish lesson students test different polishes and check performance. 

Students test water for its quality and record their information.In this water quality instructional activity, students investigate water for pH, macro invertebrates and identify its characteristics. Students complete worksheets on their...

Learners test the adhesive strength of different tapes. In this adhesive instructional activity, students conduct an experiment to test the shear strength of the adhesives, take measurements, record data, and draw conclusions to explain...

Learners test the stickiness of natural substances. In this adhesion as a property of matter lesson, students build a tool to test the adhesion of natural "glues" such as honey, peanut butter, flour and water paste, and jelly. Learners...

Students conduct an experiment with bubbles.  In this observation and comparison lesson, students read Bubbles, Bubbles, Everywhere and conduct an experiment where they test different kinds of liquids to see which is the best for a...

Students determine density and hardness of wood samples based on several investigations. For this physical science and music lesson, students visit four centers and perform tests on wood samples to determine densities and hardnesses....

Eighth graders build a structure that is able to withstand a simulated earthquake. They research earthquakes, earthquake measurement, and society's preparation for and reaction to them. Pupils build models and present them to the...

Students examine fossil fuels, nuclear and renewable fuels. They study investigate types of heat transfer such as convection, conduction, and radiation. They complete crossword puzzles based on the vocabulary. They design, construct and...

Seventh graders investigate the vitamin C content of orange juice. For this chemistry lesson, 7th graders analyze the variables that cause result variation in their experiment. They design a new experiment to test variables in question.

Students examine the four forces of flight. In this flight lesson, students test to see which types of items will fly. Students make predictions on whether the item will fly or not. Students gain knowledge about lift, gravity, thrust and...

Learners simulate the movement of the Earth using their body motion. In this earth science lesson, students explain how this causes seasonal changes on Earth.

Students investigate acids, bases,and pH. They test the acidity and basicity of various household items using litmus paper. Using their results, they rank the substances according to pH and identify the contributing chemical on the label.

Students demonstrate simple circuits and find the differences between parallel and serial circuits.  In this electronic lesson plan students work in teams to test different designs using a low voltage light bulb.
