Hands-on investigation of Riemann sums becomes possible without intensive arithmetic gymnastics with this interactive lesson plan. Learners manipulate online graphing tools to develop and test theories about right, left, and...

Patience is the name of the game. Using Plaster of Paris and chicken bones, learners simulate an archeological dig site. They excavate the chicken bones over a period of several days using tools and a large amount of patience.

Build upon and stack up data to get the complete picture. Using the applet, pupils build bar graphs. As the bar graph builds, the interactive graphically displays the mean, median, and mode. Learners finish by exploring the changes in...

Students describe and compare the layers of the atmosphere. They explain how to measure the temperature of the atmosphere and discover what causes the atmosphere to heat up in some places more than in others.

Students are presented with the problems of percentages and focus upon numbers in contrast to 100. They calculate problems with money and are engaged with the use of games as a teaching tool. Students also interpret data as presented in...

In this science worksheet, 3rd graders answer multiple choice questions about measurement, plants, water, fossils, and more. Students complete 25 questions.

Students discover the importance of water.  In this physical education science lesson plan, students consider mental and physical activities.  Students find their pulse and measure their heart rate. Students discuss the...

Help your young economists put the current financial situation into context with this fluid and informative presentation. Complete with a thorough list of key terms at the end and a useful navigation tool on each slide, the presentation...

Meteorologists and the tools they use are the subject of a reading comprehension worksheet that asks kids to read the attached article and respond to a series of comprehension questions.

Your class is going to love this activity. They get out their rulers, cardboard, and paints as they make Samurai breastplates. The simple art lesson lends itself to many different subjects such as, math/measurement, world history, and...

This can be used as a critical thinking exercise in congruence or as a teaching tool when first introducing the concept. Four octagons are arranged in such a way that a square is formed in the middle. With this information, geometry...

If you have a rotating office chair in your classroom, you can have physics pupils participate in this simple, yet effective demonstration of angular momentum. One partner sits in the chair, arms outstretched, holding heavy weights. The...

Take charge of your biology class by using this exciting analogy to relate the ATP process with batteries. Pupils use batteries and rubber bands to simulate the phosphate bonds between molecules in the body. They measure the distance in...

Future statisticians and potential psychics first conduct an experiment to collect data on whether a person can tell if someone is staring at them. Statistical methods, such as hypothesis testing, chi-square tests, binomial tests, and...

The Hopewell people of the central Ohio Valley used right triangles in the construction of earthworks. Pupils use the Pythagorean Theorem to determine missing dimensions of right triangles used by the Hopewell people. The assessment task...

Different colors of the spectrum travel at different speeds through media, causing them to refract at different angles—which allows humans to see their colors. Through a simulation, pupils see how air, water, and other media bend light....

Connect the size of a rolling cup to the size of circle it makes. Pupils view videos of cups of different sizes rolling in a circle. Using the videos and additional data, they attempt to determine a relationship between cup...

Can microorganisms live in the dry, cold climate of Antarctica? Young scientists view a research project measuring microorganisms in the Taylor Glacier. They record the findings from dirty ice, clean ice, boots, sediment, and more. Then...

Teach budding mathematicians how to square a triangle with an interactive that shows a graphical proof of the Pythagorean Theorem. Pupils alter the lengths of the legs using sliders. Using the inputted lengths, the applet displays the...

What is the best way to test water quality? Using plastic bottles, scholars create monitoring sensors to test water quality. Creating three different sensors allows individuals to measure water quality at different water levels.

Circles, circles, everywhere! Pupils learn all about circles, central angles, inscribed angles, circle theorems, arc length, area of sectors, and radian measure using a set of 12 lessons. They then discover volume formulas through...

Scholars go on a hunt to locate objects that best fit the measurements to create an eye-catching scale model of the solar system. 

Young scholars, in groups, estimate measurments and then select the tools needed and measure various items at Black Bayou Lake refuge.

Sixth graders estimate the measurement of angles and then measure the exact distance using an angle ruler. In groups, they explore shapes and recognize the characteristics acute, obtuse and right angles. Students sketch required shapes,...
