In this 2-day lesson focused on exponents, middle schoolers will cross the curriculum by engaging in science, history and language arts activities. Exponential growth will be explored using grains of rice on a chess board. Exponential...

Sixth graders visualize different percentages as parts of a whole on visual images. They observe alterations of photographs, and models of circles, squares and sets. This incredibly detailed, eight-page plan leads you through everything...

Physics lab groups finagle with laser lights to determine the critical angle of refraction for both water and Lucite. Because there are no detailed steps or an answer key for this enlightening exercise, an inexperienced physics...

Car crashes provide an excellent way to study kinetic energy transfer. Scholars explore energy through hands-on simulated crashes. They work together to design their own experiments and apply the knowledge gained to a situation that...

Who says scientists are boring geeks? Certainly not the narrator of a short video who dishes up the scandals associated with Tycho Brahe, a Danish scientist and alchemist (now that's two labels you don't often see together) who used...

In this calculator learning exercise, students will solve 10 equations using their calculator. Then students will turn their calculator upside down and match the word with a clue at the bottom of the page.

Students research population growth of regions of Canada. In this Social Studies lesson, students use included links on the Internet to find information about population growth in areas of Canada. A worksheet for each region is included....

Middle and high schoolers calculate the volume of cylinders. They measure the height, radius and diameter of cylinders. Following given formulas, students calculate the area and volume of the cylinder. They compare cylinders and predict...

Students investigate reaction rates.  In this seventh or eighth grade mathematics lesson, students collect, record, and analyze data regarding how the temperature of water affects the dissolving time of a sugar cube. Studetns...

Students observe and experiment with the concept of density. This is done using a simple experiment that helps them to apply scientific principles of observation and proving a hypothesis.

Students demonstrate some common operations done while using fractions based upon mathematical standards. They are also changing common fractions to decimals with estimation skills and the use of a calculator.

Using a simple method, learners explore gravity, cohesion, and adhesion. They perform an experiment in which they determine how many drops of water can fit on a penny. Afterwards, they discuss their results.

What is the area? Because there is only one problem here (and it is followed by a detailed explanation) use this as an all-class warm up. Cover up the bottom half until scholars have shared their own answers. They examine a rectangle...

Develop a definition of irrational numbers through an exploration of square roots. The 11th lesson in this series of 25 asks scholars to estimate the value of a square root. Learners observe as the estimation extends further and further...

How do you fit a tape measure around the Earth? No need if you know a little geometry! Pupils begin by extending their understanding of the Side Splitter Theorem to a transversal cut by parallel lines. Once they identify the...

Watch as acids and bases put smiles on their faces. Young chemists learn the concept of acid-base titration firsthand in a microscale experiment. Working groups collaborate, titrate, then use their data to determine the concentration of...

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

Hard boiled or raw? Which egg will you get? A hands-on activity has scholars explore the impact of conditional probability. Based on a skit from the Tonight Show, pupils model the selection of the two types of eggs using beads. They...

Use a KWL chart and discussion to explore the concept behind loans with interest based on percentage rates. Learners examine different types of interest, the history of interest loans and calculate the costs of a loan over a ten-year...

Using a TI-Nspire calculator, learners will work to better understand function notation and input/output functions. They write equations with a function symbols, identify what makes an equation a function, and graph lines in order to...

Develop young mathematicians' knowledge of two- and three-dimensional shapes with this geometry workbook. From learning about the classifications of different shapes and figures to calculating their area, perimeter, and volume, this...

Every pupil with a sweet tooth will be clamoring for this lab and analysis, particularly when they're allowed to eat the results! Volume and surface area formulas for cones are developed from models, and then extended to the printing of...

Mixtures, weighted percentages, and varying speeds make problem solving difficult. The resource give learners a strategy for tackling these types of problems effectively. 

Can a cat have 2,000 descendants in 18 months? To determine if this claim is realistic, individuals must take different pieces of information into account when justifying their responses.
