Fifth graders participate in a class activity that helps them learn some geometric terms along with their definitions. They describe relationships between two and three-dimensional shapes and analyze attributes and properties of...

Students identify geometrical shapes displayed in photographs of everyday objects in a metropolitan setting.

Fourth graders use computer drawing tools to create a house of geometric shapes.

Fourth graders predict, observe, and compare what happens when a force is applied to an object. In this forces lesson plan, 4th graders complete a 'swinging hammer' activity to learn about forces and motion.

Students create sets of similar triangles which, when fixed together with a piece of Scotch tape, form a spiral-like, segmented shape, slightly similar to the cross section of the shell of a nautilus.

Students discover that four special segments have a common intersection point. They identify the position of the intersection point in triangles. They produce conjectures about areas of the divided triangles.

Students prepare for or evaluate their experiences in learning about animal persistence. This is part of a multi-segmented unit on animal living, adaptation, and survival.

Students write about a time they were made to feel different, and when they were on the other side of the equation. They read other first hand accounts of times in history when people were made to feel like outsiders.

Students examine the effects on motor functions in mice. They make observations and graph their data. They analyze the data and draw conclusions in each of the three experiments.

Students investigate the concept of lung capacity. They use flow meters to measure the maximum capacity of themselves and others. The data is collected in order to make some conclusions concerning the mean of individual lung capacity....

Students explore seasonal change in the environment around their community. They investigate how changes in climate are affecting hunting, trapping, fishing and berry picking around their community. Students write about the...

Students investigate the potential toxicity of water samples using California blackworms to test water quality. They observe the worms' behaviors in different water samples and determine which sample has the highest toxicity. At the...

High schoolers, using directed questions, identify five internet resources. They use these resources to identify relevant information by highlighting those sections that address the provided questions. Students present the answers to...

In this math worksheet, middle schoolers find the solutions to the problems that involve solving equations with and without rational expressions.

In this antonyms worksheet, students complete sentences in column A matching italicized words to their antonym in column B, 10 sentences total.

Young scholars identify toxic household products. In this ecology lesson, students research on the health effects, rating and disposal of these products. They rank them based on the danger they pose.

Explore the world of acute triangles in this mini-lesson. Explores its properties, how to create it, and other interesting facts related to acute triangles.

This MathWorld site gives a short discussion on acute triangles with links to related terms and topics. The site offers a discussion on the least number of acute triangles to compose various polygons, and a discussion on the relationship...
