In this matter and change worksheet, students answer 24 questions on topics such as elements, compounds, mixtures and chemical reactions. Students answer questions about the properties of matter such as their physical state and shape. In...

Do your young mathematicians need practice getting familiar with comparing decimals and fractions? This instructional activity is designed to allow youngsters to visually represent the decimals that are provided by shading a...

Students investigate mixtures made of water and familiar solid materials. They observe and discuss the changes that occur immediately and set the mixtures aside for a day. Finally, students observe the mixtures, note changes, and graph...

Students study about chromatography, a process used to separate mixtures.

Students observe that colored markers are a mixture of many different colors by performing a chromatography experiment. They make observations, record information, and make generalized inferences from their observations.

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.

In this idea gas worksheet, students review Dalton's law of partial pressures, vapor pressure, relative humidity, and dew point. Students answer 3 problems.

In this story problem activity, students read story problems, write equations, and solve. They use the law of sines, the law of cosines, the distance formula, and rates to solve problems. This two-page activity contains seven story...

In this equilibrium worksheet, students determine what effect a catalyst has on the rate of a reaction and the activation energy. Students explore how the equilibrium shifts when different stresses are added to a compound. This worksheet...

In this dimensional analysis worksheet, students solve six word problems using dimensional analysis to solve for an unknown. These include finding density, and converting from one unit to another. They also categorize samples as...

Young scholars construct a water filter. In this engineering lesson, students discover how to construct a water filtration system. Young scholars work in groups to sort tools by their properties. Students analyze and construct a water...

Third graders use the scientific method as they separate the colors used in ink. In this chromatography lesson, the teacher introduces students to how chromatography is used in several careers, then students perform an experiment to see...

In this systems of equations worksheet, students solve 6 systems using the substitution method. Students then set up and solve 2 systems of equations word problems, one being a mixture problem.

Learners discover that a system of linear equations models this mixture of quinoa and corn in a collaborative task. Your learners receive all the relevant information in this second of three variants of tasks that ask them to find...

Don't table the discussion on equivalent ratios — do it now! Scholars create tables of equivalent ratios to represent contextual problems. Pupils go on to use the tables to answer questions within the context. The lesson is ninth in a...

A mixture of quinoa and corn is for dinner in this collaborative task that sets up nicely as a system of linear equations. Your supper guests discuss numerical precision and percentages as they formulate a plan of how to solve the problem.

Aunt Barb's salad dressing is a mixture of oil, vinegar, salt, herbs, and a pinch of math. Fifth graders add the fractional measurements of ingredients to find a total amount. The fractions have unlike denominators. After finding the...

Learners will shout "Eureka!" in this quick but deep activity replicating the famous bathtub experiment of Archimedes. Given the scenario of a king with a suspected fake crown, young investigators develop formulas using density to...

Scholars demonstrate understanding of kinematic graphs through matching dot graphs to position time graphs, dot graphs to velocity graphs, and a mixture of the two. If users feel stuck or confused, a Help Me! button offers an explanation...

In this conversion factor worksheet, students convert 15 problems within the SI system of measurement. They show their work and indicate the proper units.

There is more than one way to answer a question; especially when you have fractions in measurement. Here are three questions with real-world situations in which 5th graders are asked to provide answers in three ways: a larger unit of...

All chemical reactions require energy. To explore thermodynamics, classes read and discuss its laws, exothermic and endothermic reactions, enthalpy in many forms, calculate enthalpy problems, and use Hess' Law to calculate enthalpy of a...

Students make simple observations, test mixtures, and make generalized inferences from their observations. They observe bleeding of colored inks with water.

In this health and illness worksheet, students match the problems with the remedies given. Students complete 16 matches total.
