Examine wood bugs and their habitat. Learners gather wood bugs and examine their bodies. Then discuss their body parts and how they help them survive. They also predict where they think wood bugs live to then graph the class results.

In this rounding off practice, students determine the proper number of significant figures in numbers, in calculations of addition, subtraction and multiplication.

The 20th lesson in a 21-part series connects the wind data and expectations of a turbine to whether such devices should be built in your area. Scholars begin with estimating the wind potential at school by using long-term climate...

Young scholars investigate how to estimate the age and size of turtles, and examine variability in scientific data. They read an informational handout, identify the parts of the shell, measure the shell and estimate the age, and record...

In this student exploration-weight and mass activity, student use the Weight and Mass Gizmo to answer questions and fill in charts with estimating and measuring.

Students use prior knowledge of angle and lines as they conduct an experiment with a rolling marble to determine the shape of a mystery object located under a metal pie tin.

Although the focus of this worksheet is the neutron, you cannot talke about them without also dealing with protons and electrons! Chemistry kids fill in a table of 14 elements, identifying the mass, atomic number, isotopic symbol, and...

How much rain can that cloud make? Through a simulation, the class estimates the amount of candy rain contained in different cup clouds. After probing the clouds using different methods, class members adjust their estimates. Participants...

Sixth graders investigate the various types of pollutants found in water and ways to help prevent water pollution. Through a hands-on experiment, students create samples of polluted water by mixing water with vegetable oil, dirt,...

Space science and math collide in this inquiry that investigates launching times for antacid-tablet rockets! Upper elementary or middle school learners collect data as they launch these mini rockets. They apply concepts of place value...

This lesson entails the viewing of two videos to get an overview of force and its application. The lesson covers how vectors use force in real-world situations.

In this significant figures worksheet, students solve forty eight problems. They identify significant figures in numbers, they complete calculations of addition and subtraction and identify significant figures, they multiple and divide...

In this SI units worksheet, students solve 6 problems including converting from one unit of measurement in the metric system to another, estimating the mass of objects, and using the density of a metal to find its volume given the mass.

Students demonstrate how to use math skills to measure their lung capacity. In this human biology lesson, students use a clear plastic container, measuring cup and rubber balloons to demonstrate how the lungs work. Students estimate the...

Ninth graders select and build one of five different paper airplane designs and test them for distance and for time aloft. Part of this activity is designed to explore NASA developed software, FoilSim, with respect to the lift of an...

Students become familiar with map coordinates. They establish the frequency of earthquake occurrences and study the location and magnitude of earthquakes. To establish the location of plate boundaries.

Fifth graders determine that carbon dioxide is a gas given off during respiration and that oxygent is the gas that is absorbed during respiration. They determine the air capacity of the lungs.

Sixth graders set up an ecosystem, investigate conservation techniques, develop an action plan for conservation, and various other activities to explore the ecosystem.

Students construct simple altitude tracking devices for determining the altitude a rocket reaches in its flight. They estimate the altitude a rocket achieves during flight.

As part of a larger site called "Getting started in Chemistry," this site examines significant figures and claims to teach the user "how to avoid telling lies with numbers."

This site from the University of California provides a lengthy and intelligent discussion of sig figs, absolute and relative precision, accuracy, precision in calculations, rounding off, and the whole shooting match of how we report what...
