How confident are you? Explore the meaning of a confidence interval using class collected data. Learners analyze data and follow the steps to determine a 95 percent confidence interval. They then interpret the meaning of the confidence...

Conduct an experiment to determine the accuracy of pedometers versus pedometer apps. Class members collect data from each device, analyze the data using a hypothesis test, and determine if there is a significant difference...

Students discover the relationship between the circumference of a circle and its diameter. They find the length of an arc of a circle.Students use estimation strategies in real-world applications to predict results (i.e., interpolation...

The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

An interesting instructional activity on hypothesizing about the diameter of a drop of blood that is splattered. To test their theories, learners work in groups to make blood droplets splatter from different heights. They use graphed...

Learners construct a model of an electromagnetic spectrum using play-doh and string. They use exponents and plot the radio/microwave, infrared, and visible bandwidths of the spectrum.

Students examine the built environment and infrastructures of their community by constructing contour equipment, using the equipment, and comparing their results to current topographical maps of the same area

Can you name the three planets with rings in our solar system? Everyone knows Saturn, many know Uranus, but most people are surprised to learn that Jupiter also has a ring. The third in a series of six teaches pupils what is around...

Students explore the concept of measurement. In this measurement lesson, students discuss what specific measurement tools such as an odometer measure. Students recite a measurement poem. Students make a foldable with conversion units...

Use a variety of whole fruits to represent the different planets in the solar system to introduce scale sizes to your math or space science class. They follow suit by creating a non-scaled model of the solar system using specific-colored...

Line dancing is the repeating of a pattern of steps, done to music. Teach youngsters how to line dance and they won't feel so awkward when they grow up. Let them experiment with creating their own patterns and teaching their classmates....

Students identify and demonstrate a positive learning attitude and use basic concepts and skills. Learners also communicate clearly in oral, artistic, written, and nonverbal form. Finally, students participate in the daily data...

Explore the concept of ratios, unit rates, and proportions. Learners convert fractions and percents to decimals. They discuss rates and where they can be found in the real world. A hands-on experiment and numerous flash cards and...

Prepare your class for the real world and learn the basics about credit and the principles behind using it wisely. The activity includes handouts that explain the necessary vocabulary and concepts to understanding credit. After reviewing...

Sometimes you need to play a game in order to reinforce learning. Use Bingo cards to review the equivalents for both dry and liquid portions. Playing Bingo helps learners to practice recognizing measurement units, abbreviations, and...

Young explorers review the basic shapes (circle, triangle, square, rectangle) and practice putting them together to make new shapes. Given an outline of a pond, they recreate it by combining other shapes.

Students, using a map, drawing or aerial view of a pond, represent the shape of the pond using simple geometric shapes or fractions of those shapes. They identify the numerator and denominator in each fraction created.

Students study how to find prime numbers. They investigate the teachings of the mathematician Eratosthenes and apply his theory of prime numbers less than 100.

Students measure distances and report them in fractions, convert fractions to decimals, and multiply decimals.

Students practice estimating and counting and using a ruler to measure distance.

Young scholars estimate the distance from Baltimore to Philadelphia via the water route before the Chesapeake and Delaware Canal was built. Students study canals and how transportation and economic necessities dictate the building of a...

Students review the definition of a parabola. They trace a parabola by locating points the same distance from a point as they are to a line. Students develop an equation for a parabola with its vertex at the origin. Students solve...

Students calcute distances using trigonometry and angle measurements. They estimate the width of the Trig River, measure it and compare their results with their classmates. They collaborate with a group to research and find the results.

New skills are developed as young scholars use graphing calculators and ranger technology to capture and graph the sequence of bounces a ball makes when dropped. After recording the height of four or more bounces, they use the collected...
