Density: the reason a giant pumpkin will float, but a tiny cranberry won't. Lesson begins with a demonstration of two of the same-sized cubes having different densities. Then pupils take eight cubes, each of the same size, and have to...

First graders investigate the Commutative Property of Addition. It is introduced using models such as students, counters, balances and dominoes. They discover the order of the numbers in an addition sentence does not change the result...

Students explore polymers by designing and preparing an inexpensive and effective reusable ice pack. They develop and test a design for a reusable ice pack in the science lab. Students apply chemical and physical properties of polymers...

Seventh graders describe and conduct an experiment that identifies the physical properties of light. They explore sources of visible light and an electromagnetic spectrum. Students explain the conversion of one form of energy to another.

In this three- and two- dimensional geometry worksheet, 7th graders solve 12 various problems related to geometric shapes and measurement. They first use paper and a pencil to sketch the front, side, back, top and bottom views of each...

In this review of math skills worksheet, learners determine elapsed time in minutes, compare two-digit numerals, add values of money, identify an addition property and a solid figure. Students solve five problems.

Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.

Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

The objectives in the resource allow students to explore the characteristics of simple solid shapes. Youngsters learn to recognize the face shapes, corners, and edges that make up 3-D figures by filling in a chart. Lastly,...

Students investigate properties of circles. In this geometry lesson, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.

Sixth graders develop a rule for finding the volume of rectangular solids using colored cubes. They investigate the properties of solid figures and find the volume of an object by counting units. Students fill spaces with standard-sized...

Young scholars construct polygons. They identify attributes of three-dimensional shapes. Students name common three-dimensional shapes. They draw three-dimensional shapes, and sort three-dimensional shapes. Young scholars use K'NEX...

Learners record scientific observations in a science journal.  In this season lesson, students make observations about each of the seasons and record in their journals.  Learners record organisms response to seasonal changes...

Young scholars investigate the effects of radiation exposure and how it can effect objects on earth and space. They conduct research using a variety of resources and use the information to create a project that is reflective of good...

In this chemistry of art learning exercise, students read about the chemical reactions that turn art made of different metals colors. They answer three questions about the chemical reactions related to metals and art.

Let's paint the town equal parts yellow and violet, or simply brown. Pupils calculate the amount of blue and red paint needed to make six quarts of brown paint. Individuals then explain how they determined the percentage of the brown...

Get a line on the snakes. The assessment task requires the class to determine the species of unknown snakes based upon collected data. Individuals analyze two scatter plots and determine the most likely species for five...

Students participate in a series of hand-on, online, and multimedia activities to examine 2 dimensional and 3 dimensional shapes. They describe common geometric solids. They construct rectangular prisms using straws and ribbon.

The history of math is fascinating! Utilize a woodcut primary source image from 1492 and posters from the 1930s to help geometers apply their volume-calculation skills to real-life questions. 

Seventh graders are able to demonstrate the harmful effects of an acidic solution. They become aware of the harmful effects of acid rain. Students make predictions before they began the experiment. If vingegar contains acid, then how...

Students work with three dimensional objects. In this geometry lesson, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.

Students relate chemistry to an object they use everyday. They research information related to chemistry and create their own webpage. They are to keep their page up to date as new observations are taken.

Students investigate orthographic drawings. In this geometry lesson, students identify properties of three dimensional drawings in space. They solve problems using volume and area formulas.

Why do some items feel colder when they are the same temperature? How should you keep your soda cold? What makes the wind blow? These are just some of the things middle schoolers discover when completing a lesson on...
