In this human population changes in survival worksheet, students interpret and plot data to understand the differences in human mortality and survivorship between historic and modern times. They investigate how these changes influence...

Young scholars investigate mass-mass relationships using potassium carbonate and hydrochloric acid. In this mass-mass relationship lesson plan, students measure a certain amount of potassium carbonate and determine how much hydrochloric...

Students investigate mass-mass relationships in the lab. In this mass-mass relationship lesson plan, students mix sodium carbonate with hydrochloric acid to produce sodium chloride, water and carbon dioxide. Students use the amount of...

High schoolers read about the Spitzer Space Telescope and the technology used to learn about planet composition. They calculate the radius of a planet, the size of a planet, the average density of a planet and the likely core composition...

Space science and math collide in this inquiry that investigates launching times for antacid-tablet rockets! Upper elementary or middle school learners collect data as they launch these mini rockets. They apply concepts of place value...

Investigate perimeter and area of polygons! In this measurement lesson, learners use index cards to create rectangles and trace their hand to estimate its area and perimeter.

Learners investigate matrices by exploring addition, subtraction and multiplication of matrices.  Students find the determinant and inverse of a matrix.  The lesson includes a set of practice problems

Investigate the use of ratios in scale drawings. Learners scale objects up or down using ratios then find the actual size of something using ratios. They apply their knowledge of ratios as they make their own telescopes in science...

Students investigate polynomials. In this algebra lesson, students solve problems dealing with multiplication of polynomials by using the distributive property and the FOIL method. Students also describe how the...

Some background information about density and Newton's Laws of gravitation and motion assist pupils in the following experiment. The procedure will help them further their understanding of gravity, pendulums, and a drop-ball experiment....

Using the TI-Nspire calculator, statisicians identify outliers and their effect on the least-squares regression line. In finding the line of best fit, they determine what points will affect the least squares regressions and what points...

Students investigate topology. In this Applied Science lesson students explore higher, more abstract mathematics using tangles. Students make topologically related shapes.

Investigate equivalent fractions with your class. They compare and order fractions. Then they work cooperatively in groups to experiment and problem solve with fractions using a game format. Multiple resources are provided.

Investigate multiplication problem solving strategies by working with base 10 blocks. Learners decompose problems with a Merlin the Magician theme. Multiple resources are provided.

Resource links to a video, satellite images, data, and photographs of glaciers provide emerging earth scientists the opportunity to examine how the ice has been retreating over the years. A data table is included for pupils to record...

Inquiry-based learning and investigations form the basis of a deep understanding of quadratic functions in a very thorough unit plan.  Learners develop recursive and closed methods for representing real-life situations,...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

The scientific issue of carbon-14 dating and exponential decay gets a statistics-based treatment in this problem. The class starts with a basic investigation of carbon content, but then branches out to questions of accuracy and...

Three days of race car design and driving through the classroom while guessing probability could be a third graders dream. Learn to record car speed, distances traveled, and statistics by using calculation ranges using the mean, median,...

To understand the controversy surrounding the US 2000 presidential election, class members investigate the rationale behind the Electoral Collage, the intimidation involved in the election of 1876, and the 2004 American League...

How do you find the measure of an arc? Learners first review relationships between central and inscribed angles. They then investigate the relationship between these angles and their intercepted arcs to extend the Inscribed Angle Theorem...

Computers are useful for more than just surfing the Internet. Pupils first investigate scatter plots and estimate correlation coefficients. Next, they use Microsoft Excel to create scatter plots and determine correlation...

Test probability concepts with an activity that asks pupils to first complete a task investigating false positive in medical testing and then to evaluate sample responses to the same task.

One block, two blocks, white blocks, gray blocks. In the high school assessment task, learners investigate patterns of sidewalk stones to develop a quadratic expression for each colored block. Young mathematicians then use the expression...
