In this activity, students are asked to decide which would melt faster: a large block of ice or the same block cut into three cubes. The activity is one of 80 mathematical challenges featured on the FigureThis! web site. The animated introduction to this activity notes that surface area and volume are important to the work of architects, interior designers, and chemists. Students are encouraged to compare the surface area of the ice cubes to the larger block. The complete solution demonstrates h

Gone fishing : my, my little fish, how you've grown!

Opening with a cartoon showing the weights of three combinations of fish, this activity challenges students to determine the weight of each fish. This activity is part of the Figure This! collection of challenges emphasizing real-world uses of mathematics. The introduction discusses algebraic reasoning and notes its importance to scientists, engineers, and psychologists. Students are encouraged to begin by adding the weights on all three scales. The answer page describes three strategies for sol

In this activity, students explore the nature and impact of friction. Students will observe, predict and record an object's motion over smooth, slippery and rough surfaces. These tasks will include an introduction to basic statics and dynamics in engineering through a discussion of forces and friction and a hands-on activity. Learners conduct 2 demonstrations using marbles and coins to learn about friction. Forces, simple vectors and free body diagrams which depict the forces can be discussed wi

Logic for Computer Science: Foundations of Automatic Theorem Proving

This book is intended as an introduction to mathematical logic, with an emphasis on proof theory and procedures for constructing formal proofs of formulae algorithmically. This book is designed primarily for computer scientists, and more generally, for mathematically inclined readers interested in the formalization of proofs, and the foundations of automatic theorem-proving. The book is self contained, and the level corresponds to senior undergraduates and first year graduate students. However,

The Age of Einstein

The Age of Einstein, is a brief introduction to Einstein's Theories of Special and General Relativity. It is a book for the inquisitive general reader who wishes to gain an understanding of the key ideas put forward by the greatest scientist of the 20th-century. No more than a modest grasp of High School Mathematics is required to follow the arguments.

Online Poetry Classroom

"Songs My Teacher Taught Me," created by Teaching Fellow Anthony Consiglio, is a series of three lesson plans intended to guide students through approximately one month of poetry study. This unit involves minimal technology requirements but extends across a wide range of poetry. Of the eighteen poets included; eight are women, six are African-American; two are nineteenth-century poets and the three lesson plans are thematically broken into "What is Poetry?", "Poems of Childhood," and "Self and S

Light, Matter, and Energy

This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they are introduced to Einstein's life and work with four engaging and kid-friendly areas. Equation Invasion, a look at the world's most famous equation about the relationship between energy and mass. Web Master, the scientists whose ideas and discoveries shaped Einstein's career. Light the Way, an introduction to "the fastest thing in the universe" and the waves it travels in. E

Igneous Petrology

This PowerPoint presentation is part of the Whitman College petrology course. The presentation provides an introduction to the structure of the earth in the context of the generation of igneous rocks. Slides in the presentation cover the composition of layers of the earth, P-wave and S-wave velocities through layers of the earth, pressure and heat characteristics of the earth, and regions of igneous generation within the earth. This resource is part of the Teaching Petrology collection. http://s

Igneous and Metamorphic Petrology Class Materials

This web site is maintained by John Winter of Whitman College, and contains 31 PowerPoint presentations for an igneous and metamorphic petrology course. The course and the lectures are keyed to his text, An Introduction to Igneous and Metamorphic Petrology. The PowerPoint presentations are organized by chapter and contain many maps, graphs and illustrations. Each chapter is a separate PowerPoint file that can be downloaded and modified to suit the user's needs. In addition, the website includes

Information literacy: not just for students

Good Internet research skills are important for teachers, too. This article provides an introduction to "information literacy" concepts and a list of references for teachers and media specialists.

KS2 Numeracy SATs revision 4

The presentation (introduction) revises what a fraction is, how to make equivalent fractions or write fractions in their simplest / lowest terms, how to change between improper fractions and mixed numbers and finally how to work out a fraction of an amount. The levels test these aspects of fractions. The final level tests all of the skills. Most answers are entered using an on-screen keypad, with some multiple choice questions. The order of questions is randomised. Progress is tracked and numero
