A scenario is presented for chemistry techs to address. Using titration techniques, they must analyze hydrogen peroxide solution samples. They evaluate accuracy and precision in the process. They also gain experience consulting the MSDS...

This is the grown-up version of the classic "float an egg in salt water" experience, plus an experiment in soap making. High schoolers explore density, but more importantly, practice accuracy, precision, and the use of significant...

Hold a free-throw shooting challenge in your engineering class! Each team must design a contraption that will fire off a "robot arm" or, more specifically, a catapult, to send a Ping-Pong ball into a basket. Use this as an opportunity to...

Students explore motor skills by creating art projects from apples. In this hand-eye coordination lesson, students utilize a knife, red apple, and different art supplies to create a person's face on the fruit. Students work slowly with...

In this significant figures worksheet, students make measurements in the lab using the metric system and answer questions about the proper way to represent their measurements using significant figures.

High schoolers define accuracy and precision, and differentiate between the two terms, apply the concepts of accuracy and precision to a given situation and correctly apply the concept of significant figures to measurement and...

The difference between accuracy and precision is fundamental for high school science learners. Using test kits for nitrate concentration in water, they compare readings with each other. They consider the accuracy, precision, and bias of...

In this measurements worksheet, students fill in 10 blanks, determine if statements are true or false, match 6 terms with the appropriate definitions, and solve 2 problems. Topics include converting to scientific notation, identifying...
