Is butter better? In terms of saturation, young chemists find out! Using titration methods, they will compare the degree of saturation of butter with that of margarine. Knowing the unsaturation, they can make conclusions about the...

Students examine how effects of farming practices in the early 20th Century contributed to severe soil erosion of a large portion of the North American grasslands.

Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand. 

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

For this science worksheet, students take a close look at the composition of air while focusing on the content of oxygen. They use clay to model the amounts.

Learners develop a comprehension of parts per million as a concept. They work in teams to create successive dilutions of a solution to reach a parts-per-million concentration. Students list what they think the atmosphere is made of. They...

In this comet learning exercise, students will read information about the Comet Halley that has been collected by recent space probes. Students will use this information to complete 7 short answer questions.

For this redox reaction worksheet, high schoolers perform a redox titration to determine the number of iodide ions that react with each mole of iodate (V) ions in a solution. They calculate their answer using a given equation.

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

Tells the story of how Archimedes discovered the Archimedes Principle and his water displacement method for determining the volume and density of an object. Provides an explanation and several examples of how it is done.

Students discover the concept that density is a characteristic property of water by measuring the volume and mass of water and calculating its density.

In this activity, students' will use a force sensor to measure the weight of a water filled funnel as it drains. They analyze the weight versus time data and describe it using concepts of slope and intercepts of a linear function.

How much water do you use everyday? Find out in this engaging investigation, where you compare your water usage with your classmates and other people around the world. An exploration filled with lots of math and science that students are...

Students are introduced to our planet's structure and its dynamic system of natural forces through an examination of the natural hazards of earthquakes, volcanoes, landslides, tsunamis, floods and tornados, as well as avalanches, fires,...

In this lab, students will measure and combine colored liquids to receive the expected results. The intended outcome would be to take primary colored liquids, measure them and combine them to create a "rainbow" colored set of water in...

Students will use two different methods to determine the densities of a variety of materials and objects. The first method involves direct measurement of the volumes of objects that have simple geometric shapes, while the second uses the...

In this first part of a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate the densities of several common, irregularly shaped objects with the purpose to resolve confusion...

Students act as chemical engineers and use LEGO MINDSTORMS NXT robotics to record temperatures and learn about the three states of matter. Properties of matter can be measured in various ways, including volume, mass, density and...
