Middle schoolers relate fractions to decimals and find and compare equivalent fractions.

Students experience the process of creating a "dance team" type routine by following a set procedure.

Students solve an environmental problem on a local river. They use their knowledge of river ecology to develop an action plan. They use river-monitoring equipment to collect river- monitoring data, including biological, physical, and...

Pupils match definitions with vocabulary words and learn basic facts about matter. Then, they see how to determine the physical characteristics of matter. They determine the mass, volume, and density of objects using appropriate tools...

Students view and discuss a video about the use of pattern block shapes to form pictures. They, in groups, form garden and quilt designs using pattern blocks and then decorate the room with their art.

Learners examine and discuss Newton's Laws and discover his contribution to physics. In groups, they participate in an experiment in which they much apply the Laws to the world around them. They describe contact and conservative forces...

Students explore how climatic factors influence the growth of plants. They create an experiment to find how variations in water, light, and temperature affect plant growth and describe how precipitation and geography can affect the...

Students solve vector problems and identify the x and y coordinates. They determine if the coordinates are positive, negative, or zero. Students solve problems and convert the x and y coordinates to magnitude and direction.

Fourth graders follow directions given in bearings. They invent their own maps using them and use a protractor to help them with their designs. Students produce their own maps with instructions for navigating the maps. The channels...

High schoolers design a cafeteria floor plan. In this area and perimeter lesson, groups create an efficient lunchroom layout on poster board by using geometric shapes and formulas as the basis for their designs. In the accompanying...

Students explore Ultraviolet detecting beads and conduct several investigations with them.  In this investigative lesson students participate in an experiment to see the harmful effects of UV light and discuss their findings. 

Students make bread and understand that bread gives us energy. In this bread lesson plan, students read the story A Trip to the Market, and learn about the importance of bread. Then they make the bread!

Students demonstrate the changes that take place when they complete their experiment.  In this battery lesson students complete a lab activity. 

Fifth graders conduct experiments in simulated water pollution using a box of items to hold "pollutants"and an aquarium, representing a waterway. They observe how "rain" from a watering can poured into the box washes the pollutants into...

Students identify the parts of the respiratory system and how they interact. They define vocabulary words and draw an outline of themselves and label the parts of the respiratory system. They distinguish between healthy and unhealthy...

Pupils 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...

Second graders explore Earth science by participating in a nature observation activity. In this four seasons lesson, 2nd graders identify the four seasons on Earth and the weather patterns they are known for. Students read several books...

Students investigate the use of multiplication and division of whole numbers to solve problems including equivalent ratios and rates.

Students create an astrolabe and locate the North Star in the night sky. They determine the latitude of the North Star, and calculate an average latitude based on class results.

Students describe how several different objects magnify a provided sentence and decide if they are good magnifiers or not. They then write a sentence describing two properties an object must have in order to be a good magnifier.

Students examine tessellations and their geometric properties. Students explore the concept of tessellations and lines, planes, angles, and polygons. Students experiment with the area and perimeter of polygons. Students analyze...

Students are introduced to the notion of surface area and volume. Students review surface area and volume by finding the area of a two-dimensional shape. They practice using the computer to create different surface area shapes.

Fourth graders explore how to find the area of a rectangular object. As a class, they discuss definition of area and strategies for finding area. The teacher models finding the area of an object by counting squares. Students observe...

Students create a new playground design to present to elementary students during Playground safety week. They review basic geometry to use in observing and recording the equipment on a local playground. They research playground safety...
