Learners investigate the basic properties of pendulums as a function of spreadsheets. Working in groups, they measure the period for a pendulum at six different lengths and record the results. They prepare a file using Microsoft Excel...

Students investigate gas laws and apply them in experimental conditions. Using an apparatus composed of a syringe and wooden blocks, they experimentally verify Boyle's and Charles' laws of gases.

Fifth graders are introduced to the atlatl system and how to test and control variables. In groups, they use the Internet to research how the system has changed over time. They test various variables and record their results in a graph...

Learners estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays

Eighth graders biew each volume container and discuss where they have seen them in their home, and how they have seen them used. They explore the different names of volume sizes and their equivalents towards one another. Students...

In this circuits worksheet, students compare voltage, current, and resistance. Students draw a battery with a resistor, switch, and light bulb. This worksheet has 6 short answer, 1 matching, and 6 drawing questions.

Fourth graders conduct an experiment to get them thinking about the invisibility of air, and to prove that air has weight.

Students discuss glaciers and the current distribution of glaciers around the Earth. They create simulated glaciers using cornstarch, shoeboxes, water, and pebbles.

Fourth graders, in groups, experiment with density and the displacement of water by creating and designing their own boats and seeing which boat holds the most centimeter cubes without sinking..

Students determine what factors effect the period of a pendulum.  In this pendulum lesson students complete a lab activity and report their findings. 

Fourth graders, acting as foresters, determine timber volumes as sawtimber or pulpwood for marketing. They find the marketable value of a tree using its diameter and volume.

Students recognize the symbol for and demonstrate the rules of set.

Third graders describe an amount of turn from a particular position to another using the 'circular' benchmarks of 0, ++, ++, ++, and full turn. Estimation language such as 'just about', 'between', 'not quite', 'just over', and similar...

Students explore the size of a kilometer and the time it takes to cover this distance. They develop a concept of a km. They measure a distance of 1 km and the time taken to cover it.

Students use seconds, minutes, and hours. They then discuss the size of a thousand. After that they read time in digital or analogue form.

Students study the three types of rock characteristics; igneous, sedimentary, and metamorphic. They are divided into three groups and each group takes one of the rock characteristics. They then act out the characteristics of their rock...

Young scholars study the Periodic Table to investigate basic properties of metals used to make coins. They discuss how historic events like the Civil War and Gold Rush had a direct impact on the trime.

Students use the internet to find reasons the rainforest is endangered and ways that affects the rest of the world. They read for information, perform experiments, locate rainforests on maps, and write about this ecosystem.

Students create an experiment in which they measure the speed of a wave and record the data in a graph. They work in small groups to write the procedure for the experiment and share it with another group for cross checking of the...

Students discuss the relationship between technology and manufacturing. They then use their ideas to construct a model of a paper board carton package. Next they view a PowerPoint presentation to learn about the history of packaging...

Second graders examine the properties of liquids and their classifications. They compare and contrast cups of different liquids and record their findings in journals. Students observe how liquids flow at various speeds and that unlike...

First graders understand that gases take up space even though you can't see or smell it. This is done through many experiments like trapping air in different sized bags, using balloons and plastic bottles, and blowing bubbles. They...

Second graders discover how matter changes from one state to another by observing melting ice cubes. They decide on means to warm the ice and predict what will happen. Students record how long it takes for the cubes to melt.

Based on a set of criteria, students will evaluate the quality of pecans.1. Bring a gram scale and papershell pecans. Provide five pecans for each student. 2. Divide the class into groups of five and provide each member with five pecans....
