What is the steepness of a hill before a unicyclist slides down it rather than pedaling down it? The simulation graphs the wheel speed versus the unicycle speed as the rider goes down a hill. Scholars control the mass of the rider,...

Fight against the current. Pupils explore the resulting path when they are crossing a river while being pushed downstream by the current. Using vector notation, learners express the speed and direction of a ferry. They finish by...

Two vehicles move at a constant rate of speed toward each other, but when exactly will they pass? Pupils use still images from a video to determine the rate of speed and when the two cars meet. Then, they watch the complete video to...

Horizontal and vertical speeds change as projectiles move through space. As part of a series on vectors and projectiles, scholars create vector diagrams to compare these speeds at various locations. They they determine the values for...

How do police determine the speed of a car that has hit a stopped vehicle? Scholars determine the momentum of the car system both before and after a collision. They identify instances where the law of conservation of momentum appears to...

Full speed ahead! Young learners conduct an activity using toy cars and ramps. They collect data on mass, speed, and time to investigate Newton's second law of motion. Ideally, they'll come up with the equation F = ma.

Speed up your scholars' understanding of ratios. Class members compare ratios related with speeds presented in different representations. They then use the unit rates to make the comparisons. 

This unit on integers includes a pre-test, a post-test, four spreadsheets, and links to an interactive web-site to support the learning of integer operations. Access to computers and the Internet are imperative to this unit. The lessons...

In this math worksheet, students answer 7 questions having to do with graphing derivatives of functions, rectilinear motion, speed and distance.

For this math worksheet, students answer 6 questions regarding functions, graphs, one-sided limits, intercepts, vehicle speed and wheel rotation.

Seventh-graders solve 20 various types of problems related to ratio and rate. They write ratios in simplest form for each given statement, to compare the area of two figures, and write two ratios equivalent to each ratio. Pupils express...

Partners or groups work together to practice the correct spelling of words. They speed-cut letters from print sources and arrange them into correctly spelled words from their lists. Newspapers are suggested, but magazines might result in...

In this chemistry exam, physics pupils complete a series of multiple-choice and short-answer questions by performing calculations on speed, velocity, magnitude, and inertia.

Students measure the direction of the wind. In this Science lesson, students make their own wind vane. Students discuss the importance of wind direction and speed.

More extensive than just a general overview of digestion and reactions, this slide show gives information about all areas of enzyme function.  Topics like the chemistry behind efficiency of enzymes, factors that affect speed of...

Learners participate in a series of demonstrations about Bernoulli's principle. They explain how air pressure varies with air speed. They write a detailed lab report about the activity. This is a great way to explore this concept.

Seven pages with 33 multiple choice questions about motion make up this activity. Calculations must be performed in order to choose the correct answer. Physics majors will solve for angles, displacement, acceleration, speed, and time for...

It can be fun to multiply by 10, 100, or 1000! Present all the info needed to make your class multiplication masters. They work through several examples, then take a one minute speed test. This resource comes with a built-in timer that...

While wildlife may not always be visible, they leave their marks behind for people to discover. A wildlife lesson plan has pupils explore the characteristics of animal tracks. They learn different types of tracks, as well as what tracks...

Get those mental mathletes thinking on their toes! Can they recall multiples of seven in these timed exercises? Scholars who have already learned multiples of seven get some timed practice as they finish this 60-problem set. They...

How fast can you finish? Scholars who have already learned multiples of nine get some timed practice as they finish this 60-problem set. They multiply nine by numbers 0-10 with a goal of both speed and accuracy. Two minutes would be an...

Useful as a speed math test or a homework assignment, this resource on equivalent fractions is sure to challenge your young learners. Thirty pairs of fractions prompt pupils to fill in the missing numerators and denominators to make each...

Here is a great subtraction assignment to use as homework or as a speed trial in your second grade class. After reviewing the basics of subtracting 2-digit numbers in three examples, learners solve 32 problems. Most of the problems...

The /r/ sound can be a difficult one, but scholars use some helpful tips to get it right. After examining the letter shape they listen to you pronounce this phoneme and describe what you are doing to create the sound. They try on their...
