Students use a balance to complete subtraction problems and weigh out the items they take away. In this subtraction lesson plan, students use a pan balance and record their equations.

Third graders review telling time. In this lesson on telling time, 3rd graders discuss various items that show length of time, including clocks, calendars and sand timers. Students review and practice what they already know about telling...

Students investigate modular clock arithmetic and cryptography. They perform basic operations in modular (clock) arithmetic and encode and decode messages using simple shift and affine ciphers.

Students calculate acceleration due to gravity.

Students describe famous people to others that do not know who they are. They complete a worksheet with a list of physical attributes. They are to describe a family member to one of their classmates.

Students explore the everyday implications of system failure. They are challenged to identify the causes of system failure.

Fourth graders discover that the inverse of squaring is finding a square root. and that square roots are found in many formulas used in many disciplines. They utilize a worksheet imbedded in this plan that gives them quite a bit of...

Students examine the difference of squares equation, and multiply binomials using the FOIL method. They complete the Case of the Missing Middle Term worksheet.

Students investigate how excess nutrients enter a body of water, and the harmful effects they have on aquatic organisms.

Students experiment with static electricity and make their own electrical circuits. Students experiment with their circuits to explore conductors and insulators. Students identify Thomas Edison as the person who invented the electric bulb.

Students examine the effects different substances have on proteins. They test different molecules reaction to water. They discover how the amount of water affects the shape of the protein.

Tenth graders apply their knowledge of angles related to a circle, radii, secants, tangents and chords of a circle. They practice using formulas related to a circle. They also apply what has been practiced to real life situations.

Students explain how the components of a cell operate as a system. Students examine a bicycle and find out if parts were arranged differently, could the system still be carried out. They look at cells as well and see what function they...

Learners will make many discoveries about how and why objects move. They will explore and manipulate the motion of objects and the forces required to control that motion (pushing, pulling, throwing, dropping, rolling, and so on). This...

Students gather (research) information on neuron structure and action potential. Students are guided to make inferences about the synapse and its relationship to neurotransmitter release and action. They are also guided to make...

Students calculate the costs for lodging and meals for a virtual field trip. They calculate the number of nights lodging needed for road and city travel and the number of meals needed, the costs for each, and input the data using...

Fifth graders discuss ways that humans pollute our natural water supply. They observe a video about water pollution. Students identify eight different ways water is contaminated. They investigate an oil spill by conducting a hands-on...

Seventh graders simplify algebraic expressions using multiplication and division to combine like items and solve for the variable. They work with inverse operations to solve equations with guided practice. Students complete various...

Livestock managers reinforce math and science skills while learning about the nutrients found in manure. They predict which animal produces the largest amount and which animal's manure contains the most nitrogen. Finally, they compare...
