Students investigate various chemical reactions when creating mixtures in ziplock baggies. For this chemistry lesson, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies are included in...

Students investigate the fixed and variable costs that entrepreneurs face. They examine how entrepreneurs identify and control their costs in order to make a profit by completing a number of included activities.

Sixth graders, in groups, observe the difference between physical and chemical changes and create a collage of pictures to show the difference.

Students use scientific method to determine cost-effectiveness of air freshener, and create PowerPoint presentations to share their results.

Students use density to identify what metal a gold colored weight is made of. They use a spreadsheet to graph the experimental density of common metals and compare the know densities to their calculated density of the known metal.

Students calculate fixed and variable costs. In this costs lesson, students read a case study about an entrepreneur and her business costs. Individuals complete the provided worksheets to find costs and make related business decisions....

Students investigate bio-fuel. In this investigative lesson, students create bio-fuel from vegetable oil waste. Students will analyze, predict, collect and synthesize data from their experiments with bio-fuel.

Second graders explain the definition of hail and sleet. In this precipitation lesson, 2nd graders discuss when hail and sleet fall and the results of hail falling.

Students discover the history of hot air balloons by watching one ascent.  In this physics lesson plan, students utilize a Montgolfier Hot Air Balloon from an earlier lesson plan and record the temperature, rate of ascent and the...

Fifth graders design an experiment in which they separate mixtures. In this mixtures lesson, 5th graders define mixtures, solutions, solutes, and solvents. They watch a video, complete worksheets, and perform an experiment to separate...

Young scholars examine the compositions and structure of diamonds. They conduct an experiment growing crystals, watch a video, and conduct Internet research.

Students explore a web-based illustrated text and interactive graphics to determine the relationship between the operation of telescopes and light. optics. They work in small groups to become an expert on one of the ten eras of telescope...

Ninth graders explore ways water moves through various reservoirs on Earth, examine how human activities change water cycle, investigate substances present in water that indicate human activity, and discuss how understanding water cycle...

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

Young scholars read and discuss Boyle's Mechanical Philosophy and his rejection of Aristotle's theory of "Forms and Qualities." They answer a given set of questions and discuss these with the class.

Students practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio and are...

Students investigate the physics of heating and cooling through conduction, convection, and radiation. Working in groups, they determine the best way to cool a can of water and warm a can of water. Temperature is taken at five minute...

In this mixture worksheet, students are given five mixtures and they determine if each is a mechanical mixture or a solution. They also identify the way each substance within the mixture can be separated from the others.

Learners explore the water cycle using educational resources. In this water cycle lesson, students use a global climate DVD to complete a scavenger hunt on the hydrologic (water) cycle.

Students explore mechanical and chemical weathering at stations. They articulate some mechanisms of chemical and mechanical weathering through exploration in a lab. Students stations describe how chemical weathering differs from...

Learners design and construct a boat out of aluminum foil and a few other simple materials. The boats then be tested by floating them in water, then adding mass until they sink. They explore the various shapes of boat construction.

Students explore the generation of magnetic fields from currents in wires and measure the magnetic field directions. They measure magnetic fields in their own environment. They also examine how moving magnetic fields can create currents.

Learners examine the concept of magnetism by doing several activities using magnets and compasses. They explore poles and polar repulsion and attraction.

Learners examine the characteristics of a tornado. They practice using new vocabulary and participate in a question and answer session. They use the internet to gather more specific information.
