Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

Ninth graders compare ancient and modern technology in water transporting. In this lesson on the evolution of the aqueduct, 9th graders build a working aqueduct model and examine its components. They explain the importance and use of the...

For this pressure worksheet, learners find the pressure of objects using the equation for pressure. They find the pressure of air in the atmosphere and the pressure of water in the ocean at different depths.

Students investigate the effects of substances on the viscosity of egg yolks. For this viscosity lesson plan, students separate egg yolks from their albumen and then add different masses of albumen back to each egg yolk. They measure the...

Your young apprentices build a function describing the percent concentration of salt in a brine. The rational function is then related to the parent function, y= 1/x, and graphed. Finally, the apprentices predict the amount of fresh...

High schoolers explore displacement. In this displacement and density lesson plan, pupils find the volume of irregular shaped objects. Afterward, they determine the volume of containers. They compute the amount of water displacement.

Sixth and seventh graders construct a "metric machine" as a kinesthetic aide in converting from one unit to another in grams, liters, or meters. They complete a metric activity on the Internet and view about five minutes of a video on...

Why is calcium good for the body? Where is it stored? Young chefs discover the importance of calcium and review a list of foods that are rich in the material. They then make delicious smoothies high in calcium! Teaching kids how to...

Explore types of angles and the characteristics of each. After observing a PowerPoint Presentation, learners tour the school facilities and use a digital camera to capture prescribed angles. Using the digital pictures and written...

Students investigate unit conversion.  In this unit conversion lesson, students will build models of square and cubic centimeters using grid paper and generate formula tables for converting units of area and volume.  The tables...

Your class is asked to use inverse operations to solve eleven equations for unknown variables or to rearrange formulas to highlight a quantity of interest. By using the same reasoning as solving one- and two-step equations, algebra...

n this geometric lesson, students define and identify two dimensional shapes based on their attributes. They complete worksheets based on the geometric concepts.

Fifth and sixth graders practice working in pairs to determine whether they can walk with constant speed. They test themselves, collect their data, draw graphs with their data collected, manipulate the data, and then draw conclusions...

Numbers that are very large or very small are difficult to express in standard notation. Pupils learn how to convert between standard and scientific notation. They also multiply and divide the numbers in scientific notation. 

Students view a quicktime video of basketball players going from Atlanta to Springfield, Mass. In this scaling instructional activity, students use a map to calculate the distance of the trip and the length of travel time. Students apply...

Learners determine the density of 1 drop of water. In this determining density lesson plan, students determine the mass and volume of a drop of water in the lab using appropriate lab techniques and calculate the density of a drop of water.

Seventh graders investigate how changes in the mass or height of a ramp can affect the change in potential energy. They discuss the concepts of work and energy, then using the four question strategy, they design an experiment that...

Students experiment to observe air and its mass.  In this air lesson, students use the scientific method to complete experiments that demonstrate the properties of air. Students view a video as follow-up.

Young scholars describe how objects in the universe range from smaller than atoms to larger than galaxies. they explain how the metric system works and compare it to the English system of measurement.

Learners investigate the concepts of hurricanes and violent weather conditions. For this violent weather lesson, students access an Internet site and watch a video about how air masses behave, how a tornado forms, how hurricanes form,...

Students investigate Nanotechnology. In this physic's lesson, students evaluate a hands-on model made from chocolate syrup and pretzels to determine the advantages of size.  Students weigh chocolate syrup to determine it's wait...

Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture. 

Two young scholars are blindfolded and each receives a cardboard square, one with pompoms glued around the edge and one with pompoms glued all over the surface. They identify what they feel. The class discusses perimeter and area of...
