This activity gives students the chance to explore area and perimeter in a problem solving setting. Nine differently-sized squares need to be tiled into a rectangular frame of unknown proportions. Three prompts of solving strategies are provided. Ideas for implementation, extension and support are included along with a printable sheet of the problem.

This lesson plan is intended to encourage learners to integrate the visual arts with science and appreciate nature. Students will create a round or square stepping stone using colored glass pieces with a mortar and sand mixture.

Students will design and build a machine to lift "barrels" of volatile chemicals from a "dangerous" spill area to a "safe" area.

In this problem students study motion along a path and the properties of a parallelogram. Students must navigate back to a starting point after traveling three legs in cardinal directions on a compass. Ideas for implementation, extension and support are included.

Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time. View a Free Body Diagram of all the forces (including gravitational and normal forces).

Learn how to make waves of all different shapes by adding up sines or cosines. Make waves in space and time and measure their wavelengths and periods. See how changing the amplitudes of different harmonics changes the waves. Compare different mathematical expressions for your waves.

Express yourself through your genes! See if you can generate and collect three types of protein, then move on to explore the factors that affect protein synthesis in a cell.

Genius Hour Unit plan created by Adam Barlow, adapted for an engineeirng design class.

How does a lens form an image? See how light rays are refracted by a lens. Watch how the image changes when you adjust the focal length of the lens, move the object, move the lens, or move the screen.

How do greenhouse gases affect the climate? Explore the atmosphere during the ice age and today. What happens when you add clouds? Change the greenhouse gas concentration and see how the temperature changes. Then compare to the effect of glass panes. Zoom in and see how light interacts with molecules. Do all atmospheric gases contribute to the greenhouse effect?

In this activity, students explore number decomposition and the powers of two. They play a number guessing game, and by the presence or absence of the secret number on each of six cards, the number can be found. An applet has the computer play the trick with the learner. The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, and ideas for support and extension.

This exploratory problem provides students a way to consolidate their understanding of halving and halves and gives students experience of mathematical proof. The students are given multiple images of squares split in half. The goal is to prove how they are correctly halved and to think of other ways to split a square into two halves. The Teachers' Notes page offers rationale, suggestions for implementation along with a PowerPoint presentation, discussion questions, ideas for extension and support, and printable (pdf) worksheets of the problem.

This problem consolidates children's understanding of halving in a spatial context and will help them to develop their powers of visualization. The students are given four different shapes and the goal is to divide them each into two parts that are exactly the same. The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, a link to an extension activity, Same Shapes (cataloged separately), and a link to a simpler activity, Halving (cataloged separately).

In this investigation, students visualize and compare volumes in solids composed of unit cubes and look for patterns in the measurements. They work systematically to organize and analyze the results. Ideas for implementation, extension and support are included.

A lesson plan for 4th grade science. Kids create a version of the marble roll project to simulate a manufacturing process.

This activity provides an opportunity for students to work on spatial visualization and number sense together. Learners are presented with a hundred grid and told there is another printed on the reverse side. They must work out the unseen numbers for several positions on the grid. Ideas for implementation, extension and support are included along with a printable sheet of grids.

This wiki page documents the STEAM Design Challenge Activity ISKME facilitated during the SLANT Summer Institute at San Francisco Unified School District July 19-23, 2010.Participants designed prototypes for an arts integration project for students and posted their ideas on the wiki.

In this lesson activity students create visual representations for the data presented in the book, "If the World Were a Village" by David J Smith and Shelagh Armstrong. Students are challenged to create different representations and reason why one representation may be better than another. Suggested representations are pictographs, bar graphs, and tables. The activity includes the problem, teacher notes, hints, and solution suggestions.

Make sparks fly with John Travoltage. Wiggle Johnnie's foot and he picks up charges from the carpet. Bring his hand close to the door knob and get rid of the excess charge.

This problem provides an interesting context to consolidate addition of fractions and requires students to develop and analyze different strategies and explain their findings. Students are asked to find a general method for expressing unit fractions (fractions which have numerators of one) as the sum of two different unit fractions. They also explore whether all unit fractions can be written like this in more than one way. The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, and ideas for extension and support.
