Students research measurements of the moon and Earth as well as the distance between the two in order to create scale models of the Earth-moon system. With a marble to be used as the moon, they must determine how large to make Earth...

Meet me in the tunnels. Scholars choose a tunnel entrance and mark it on their side of the cardboard. They describe the location to their partners and see if they can guess each other's locations. Punching a hole through the cardboard...

What does it take to show two triangles are similar? The 11th segment in a series of 16 introduces the AA Criterion for Similarity. A discussion provides an informal proof of the theorem. Exercises and problems require scholars to apply...

Students measure irregularly shaped bones, once using a variety of measurement methods and tools, and then again using standard conventions and metric tape measures. They explore firsthand that standardizing data collection makes...

In this measurement worksheet, students write 4 questions that can be answered by making measurements. Students also use estimate the measurement for 4 given objects.

Young scholars identify what factors effect global warming and how the greenhouse effect occurs.  In this environmental lesson plan students view videos then complete an experiment using a terrarium to observe greenhouse gas.

Young scholars review estimation, measurement, fractions, decimals while familiarizing themselves with a new classroom at the beginning of the year.

Ninth graders examine the rate of motion and changes in motion using a ramp and a rolling object. They conduct the demonstration, determine the average speed, and describe how a moving object can have zero acceleration and deceleration.

Students view a video clip about the building of tunnels. They discover the importance of measurement and communication between groups when building a tunnel. They participate in an activity in which they must communicate with others.

Students collect statistical data.  In groups, students play a dart game and then determine the distance between darts.  They collect the data and plot the information on a coordinate plane.  They identify the mean and the...

Sixth graders investigate physics by creating paper airplanes. In this flight experiment lesson, 6th graders utilize stationary tools to create elaborate paper airplanes which they fly on their school grounds.  Students complete...

Learners explore the world of nanotechnology by synthesizing ferrofluids in a series of chemical reactions. In small groups, they follow the procedure to create the ferrofluids using precise measuring techniques. They test the resulting...

Students investigate ways to enhance an object's flying ability.  In this model construction lesson, students construct two paper airplanes, one of which is twice as big as the first.  Students compare and contrast the two...

Here is an activity that is intended to highlight a very important issue about precision in reporting and understanding statements in a realistic scientific context. Discuss different ways of reporting the half life of Carbon 14...

In this home school support worksheet, 2nd graders review the process of measuring with a six inch ruler with a home support person. They practice by measuring small items around the house to the nearest inch.

Students explore the concept of measurement, modelling the increments on a standard ruler using cubes and grid paper. They identify the length of a line to a designated standard unit and measure specified body parts.

A comprehensive practice exam, this resource covers many areas of chemistry. The test includes 71 multiple choice questions on topics such as problem solving, chemical equations, chemical formulas, thermodynamics, acids and bases, and...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...

Explore Snell's Law using thin films. In the fifth installment of a seven-part series, pupils solve a set of problems relating to Snell's Law and use this skill during an experiment requiring the collection of reflective measurements...

Why do all sizes of pictures not show the same thing? Class members analyze aspect ratios of various sizes of photos. They determine which sizes have equivalent ratios and figure out why some pictures need to be cropped to fit...

How do you create a technical drawing? Cover the basics of technical sketching with a few practice sketches of simple shapes. A technical sketching lesson introduces the proper precision measurement techniques. Pupils progress...

Develop a model for a hanging chain. Pupils find a mathematical model for a hanging chain and then they compare their models to the precise function that models the curve. Scholars come up with a strategy to determine how close...

Does doubling mean everything doubles? Learners adjust the scale factor between two rectangles. Using the calculated measurements, pupils investigate the ratios between the lengths, perimeters, and areas of the rectangles.
