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,...

In this word problems activity, learners read and problem solve nine  mathematical word problems involving grids, measurement, compensation and angles.

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

Introduce teams to quantum dot solutions with an activity that has them expose solutions to a blacklight, observe the colors, and take measurements. Groups graph the data and analyze the dependence between particle size and...

In this chemistry overview worksheet, students calculated the volume of different gases and liquids given in a word problem. Students had to calculate the molecular mass and write the empirical formula and the molecular formula.

You will appreciate a useful learning exercise for grasping an understanding of liquid volume and practicing metric unit conversions. All of the problems involve liters and milliliters, so the conversions are very elementary. Neat...

From their sweat to the water vapor in their breath, astronauts recycle every possible drop of water while in space. After watching a short video describing the different ways materials are recycled and reused in space...

It's assessment time! Determine your young mathematicians' understanding of elapsed time with this brief, five-question quiz.

The history of math is fascinating! Utilize a woodcut primary source image from 1492 and posters from the 1930s to help geometers apply their volume-calculation skills to real-life questions. 

For this metric system worksheet, students convert measurements of volume from the English system of measurement to the metric system. They also convert within the metric system and answer questions about volume measurements.

In this metric system worksheet, students complete notes on measurements used in the metric system, the metric system prefixes and estimates of measurements of length in centimeters.

In this water on planetary surfaces learning exercise, learners read about the Galileo spacecraft and the surface of Jupiter's moon Europa. They read about the energy needed to keep the water in a liquid state on Europa. Students solve 4...

In this thermometric titration worksheet, students determine the concentrations of hydrochloric acid and ethanoic acid using a titration where they measure the temperature of the solution as it is titrated. The equivalence point is found...

For this burette-use worksheet, high schoolers are given directions for titration using a burette. They practice reaching the end point of titrations and calculate the mean volume of three trials.

In this classification of matter learning exercise, students answer 15 questions about solids, liquids and gases, types of mixtures and compounds vs. elements. They also answer 2 questions about measurement and 1 question about a biome.

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to students their different roles in the activity, the teacher reads aloud a...

A thorough investigation of cell transport is provided when completing the assignment. The first half requires biology class members to answer questions about diffusion and osmosis with the aid of diagrams. Then they fashion an...

An educational lesson allows young chemists to test the solubility of different types of salt at various temperatures. Groups create a graph using data from unsaturated, saturated, and supersaturated solutions.

In the summer of 1815, snow fell every month in New England. Was this related to the volcanic eruption of Tambora in Indonesia earlier in the year? Young scientists design their own experiments to research the long-term effect a volcanic...

What does viscosity have to do with splatter? An activity shows that the viscosity of a substance is inversely proportional to the distance of its splatter. Learners conduct the experiment by collecting data, graphing, and analyzing...

How does water pollution affect the organisms living in the water? Use three science experiments to examine how erosion and other pollutants can affect water quality. Each experiment focuses on a different aspect of pollution and...

Learn about radiation, convection, and conduction with a multiple choice worksheet. Each question prompts kids to decide what is different about each form of heat energy transfer, and what is the same.

For this identifying the weather terms activity, students read phrases about the weather and choose the term being described. Students choose 11 multiple choice answers.
