In this music worksheet, students answer 7 questions about music history. For example, "Describe the Bach influences upon Mahler in the second section of this extract."

For this voltmeter worksheet, students design and mathematically analyze a circuit they design. They also answer 17 questions about voltmeters, the voltage in given schematics, and the resistance in voltmeters.

Third graders explore forms of matter through reading, hands-on science activities, and research using the Internet. Students create a booklet, directions given, that they title and decorate, to later serve as a review visualization...

In this music worksheet, students read an excerpt about the classical sonata and how it is defined. They also respond to seven questions based on what they read in the excerpt about sonata.

Students examine how the circumference, diameter, and the relationship of Pi of a circle are related. They count the summer rings of a tree to determine its growth.

Students work together to identify the accuracy of sundials. They track the position of the sun and create a shadow plot. They discover the difference between real time and clock time.

In the process of constructing their own "rulers" Students develop a sense of the size of a centimeter and meter. Students select the appropriate "ruler" for the tasks. Finally, 3rd graders calculate the perimeter of objects using...

First graders study plants and animals and how they depend on one another. They also study that plants give energy to animals and provide oxygen needed for life. Finally, 1st graders give examples of the roles plants and animals play...

Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...

In this measurement instructional activity, students use a measuring tape to measure suggested items located in the classroom, such a table or desk. Students measure to the nearest 1/16th of an inch. They calculate the surface area of...

Eighth graders create their own cane flute. They use a model flute to gain the correct measurements and use the scientific method to construct the flute to have sound quality and pitch accuracy.

Students critique their own drawings for accuracy and make constructive suggestions prior to reworking them. They discover how scale in maps and drawing relate to relative size and distance. In addition, students comprehend the...

Students build their own wind turbine. In this physics instructional activity, students calculate the power output of their wind turbines. They evaluate their design and make the necessary modifications.

Students explore how electronic screens use only three colors to produce the colors that people see on the screen. They make and test a color wheel.

Students participate in a challenge to construct a rotation sensor with the highest degree of accuracy and repeatability. They conduct computer analysis of their sensor using repeated trial.

Students demonstrate their ability to properly make observations using a compound microscope. They prepare an onion skin slide and focus on it in both low and high power. Then they measure the diameter of one of the cells.

Second graders explore the ways in which animals differ. They discuss the characteristics of insects and spiders. Students identify the characteristics of insects and spiders. They compare and contrast insects and spiders.

Students examine how heat moves from substance to another.  In this heat absorption lesson students identify ways that heat is transferred and analyze data.

With so many specialized pieces of equipment used in a multitude of areas, there is a great need for someone with the specialized knowledge to repair these many types of equipment. From repairing cameras to medical equipment to piano...

This maker of precision instruments presents this solid article on the topic of accuracy and precision. Great discussion of types and sources of error, and quality control.

A really nice distinction here in this longish piece from the Bellevue Community College. It's not just accuracy vs. precision, but also error vs. uncertainty. This is a necessary additional consideration for any paper on the topic.

Students learn the conversion relationship between inches and centimeters through data collection. The data collected results from measuring items using inches and centimeters as the units. They use a TI-73 to input the data into lists...

The difference between accuracy and precision is explained, with a precautionary note about being aware of possible bias in the measuring instrument.
