Measuring Short-Term Recall

Compare your recall of a list of non-words versus a list of words in timed sessions. Consider whether or not there might be bias in your experimental design.

Measuring Steepness

Does the ratio of height to distance and the angle of elevation change as you move a ladder? Identify any patterns that exist between the height-to-distance ratios and the angles.

The Median

Determine the median of eleven noodles. Consider what you would or would not be able to tell about the other noodles if you could only see the median noodle.

Medieval Hats

Hats were an important part of medieval garb. Look at pictures of five medieval hats and try to determine which of the people listed wore which of the hats.

Medieval M.D.

You are a doctor in the Middle Ages with three patients to cure. Read about their symptoms and decide what medieval treatment to prescribe.

Melting Rocks

Turning solid rock into liquid magma involves changing its temperature, pressure and water content. Try your hand at melting rock to create magma.

Metronomes

Compare the ticking of a metronome to a sine wave. Use interactive metronomes to explore the phenomenon of spontaneous synchronization.

Mexico

Practice some of the vocabulary and grammar covered in the Mexico episodes of Destinos.

The Midline Cut

You can cut geometric figures into pieces that you can rearrange to form different geometric figures. Show how the midline cut of any triangle can be used to form a parallelogram.

MiniMouseLab

Use a simulation to operate an elevator and see its motion. Examine the graphs that describe the motion you produce.

Monarch Butterflies

Observe monarch butterflies and report their sightings online. Share and review the sightings with other students/classrooms to track hemispheric migratory patterns.

Ms. Anwar's Backyard

Use the slider on the graph to see all possible shapes of Ms. Anwar’s 2,000 sq. ft. backyard. Come up with an equation relating the length (x) and the width (y).

Multiplication with Manipulatives

Area models can be used for many types of multiplication problems. Work with manipulatives to create area models for some multi-digit multiplication.

Mystery Operations

The computer makes up a mystery operation and you have to figure out what it is. Keep entering pairs of numbers for the computer to calculate and try to find the pattern in the answers the computer gives until you think you know what's going on.

Name That Atom

View twelve atoms each composed of different numbers of protons, neutrons and electrons. Determine whether the atom is an anion, cation or isotope and identify the element on the Periodic Table.

Name That Function

Chart graphs of three equations. State whether each graph is quadratic, exponential or linear and explain your reasoning.

Networks

Learn about the different mathematical tools used to analyze and describe networks. Practice building networks that meet specific criteria.

Newspapers: Use Your Document Detective Skills

Read three newspaper articles, one at a time, about events of historical significance. Identify the region and era particular to each newspaper article, and answer additional questions about the topic covered.
