Students discover the relationship between the sides of a polygon and the number of diagonals that can be drawn from one vertex, the number of triangles that those diagonals form, and the sum of the interior angles of that polygon.

Third graders study the meaning of the digits an any whole numbers with up to 3 decimal places. They order decimals with up to 3 decimal places and perform measuring tasks, using a range of units and scales.

In this unit students use the traditional tale of the gingerbread man as a context for ordering and comparing lengths. They compare the length of two objects directly, order three or more objects by length and select objects that are...

Students participate in and conduct a survey to determine various class favorites. They collect, organize and display their data, interpret the results, and complete a packet of worksheets to display the information.

Students receive a miniature pumpkin and proceed through several stations to measure a variety of physical properties. The data is entered into a data sheet and the mass and volume measurements are used to calculate density. They also...

Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.

In this chemistry review worksheet, students review terms and concepts covered. Students practice metric conversions, factor labeling, temperature conversions, heat calculations, atomic structure, and gas laws. This worksheet has 3...

Young scholars calculate the length, width, height, perimeter, area, volume, surface area, angle measures or sums of angle measures of common geometric figures. They create an equation of a line of best fit from a set of ordered...

In this solubility worksheet, students calculate the final concentrations of the ions involved in a chemical mixture. Students calculate the solubility of different compounds. This worksheet has 13 problems to solve.

Students identify different woods based on their density. In this density lesson, students use a triple beam balance to find the mass and a metric ruler for the volume. They look through various wood blocks and identify what type of wood...

Sixth graders measure and investigate the densities of several objects. They, in teams, determine the mass and volume of each of the 5 objects and record the measurements in the data table.

Students analyze velocity and how it is determined. They experiment with velocity in order to measure and calculate the magnitude of speed. They use examples in their novel "Skateboard Renegade" to relate velocity to real life situations.

In this stoichiometry worksheet, students practice calculating mass or volume for specific chemical reactions. This worksheet has 5 problems to solve.

Students discover scales for both the solar bodies' relative sizes and their distances from the sun. They find equatorial circumference and volumes of their solar bodies. Students apply estimation strategies and proportioanl reasoning to...

Students examine various triangles and discuss how similar triangles have sides that are proportional. They utilize an ancient Egyptian method to determine the height of a flagpole.

Young scholars collect data and make observations on how given element samples respond to the field of a magnet and they calculate the density of the samples by finding the mass and volume.

In this gas worksheet, students apply the gas laws by calculating the mass, volume, pressure, or temperature for given gas reactions. This worksheet has 13 word problems.

In this decimal word problems worksheet, 5th graders solve 6 word problems with addition and subtraction of decimals. This worksheet in interactive and students will receive immediate online feedback.

In this elements worksheet, students give the symbol for given elements. Students determine the number of protons, electrons, and neutrons for atoms. This worksheet has 9 fill in the blank and 5 problems to solve.

Students use scientific measuring tools to collect and use scientific data. They determine the density of four different objects by using their data to explain why objects have similar/different densities even though they are both made...

For this 9th grade science review worksheet, students complete 63 true or false questions on topics such as atomic notation, isotopes, covalent bonds, Ohm's law, and electric circuits.

Young scholars explore the surface ratio of an object.  In this surface area to volume lesson students construct a data table, make calculations and create a graph. 

In this decimals instructional activity, learners solve word problems containing decimal numbers and one step problems. Students complete 5 problems.
