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...

Students participate in an investigation in which they compare a polyethylene bag designed for recycling or disposal with a polyethylene food storage bag. Students use hexane to determine the differences between the low density...

Groups of students rotate through five classroom stations to estimate, measure, and record volume, length, weight, mass, and area using both customary and metric measure. They evaluate their data to determine how close their estimates...

Fifth and sixth graders compare decimals to the place-value structure in the base-ten number system. They represent fractions as parts of unit wholes, as parts of a set, as locations on a number line, and as divisions of whole numbers....

Space scientists investigate the cosmic phenomena in order to search for answers to possible origins of the solar system. They consider the concepts of elements and  isotopes. Data is analyzed looking at tje abundance of elements...

In this chemistry exam worksheet, students solve fifteen problems related to acids and bases, rates of reactions, and half life.

This exam is aimed at assessing college level organic chemists. Ten problems are to be solved and include drawing molecular structures, assessing degrees of saturation, ordering alkenes according to stability, and explaining chemical...

Teach your class the descriptive characteristics of soil. Provide information about particle size and a flow chart for assessing texture. Soil scientists then analyze samples and hypothesize which would be the best type for a rain...

Does technology affect our intelligence? Stefanie Olsen's article, "Intelligence in the Internet Age," and the thought provoking reading comprehension questions that follow, are sure to generate a lively discussion. 

Covering both permeability and porosity, scholars perform a hands-on experiment testing various soil types. The material includes a pre-lesson worksheet to help focus pupils on the task at hand. 

Avoiding lab safety rules will not give you super powers. The lesson plan opens with a demonstration of not following safety rules. Then, young chemists practice their lab safety while finding the mass of each item in a mixture and...

How much land does a parcel hold? How much fertilizer does it take for a field of corn? Pupils answer these questions and more as they apply ratio reasoning and unit analysis. 

What a waste! The last installment of a nine-part technology/engineering series teaches learners about medical waste disposal systems. Conducting a simulation allows individuals to understand how monetary considerations constrain waste...

What does stretching a balloon have to do with equilibrium? Groups explore preconditioning by stretching a balloon to a point of equilibrium. They then measure the amount of force required to stretch the balloon to the same point several...

There are many ways to correlate coffee to life, but in this case a worksheet looks at the price of two different sizes of coffee. It requires interpreting a graph with two unknown variables, in this case the price, and solving for...

Strive to think outside of the quadrilateral parallelogram. Worksheet includes two problems applying prior knowledge of area and perimeter to parallelograms and trapezoids. The focus is on finding and utilizing the proper formula and...

Get a line on the snakes. The assessment task requires the class to determine the species of unknown snakes based upon collected data. Individuals analyze two scatter plots and determine the most likely species for five...

Scholars identify and continue the numerical pattern for the number of wheels on a train. Using the established pattern and its inverse, they determine whether a number of wheels is possible. Pupils finish...

Many problems in life have more than one possible solution, and the same is true for advanced mathematics. Scholars solve seven problems that all have at least two solutions. Then three higher-level thinking questions challenge them to...

It's time to redesign the healthcare system. The seventh installment of a 9-part technology/engineering series teaches future engineers about patient flow and how to design healthcare centers to improve flow. Classroom simulations allow...

Here is a (great) lesson on using parentheses! The task requires the expression of ages using algebraic expressions, including the distributive property. Pupils use their expressions to determine the individual ages.

What figure is formed by connecting the midpoints of the sides of a quadrilateral? The geometry assessment task has class members work through the process of determining the figure inscribed in a quadrilateral. Pupils use geometric...

Does the number of calories you eat affect the total time you sleep? Young mathematicians tackle this question by collecting their own data and making comparisons between others in the class through building scatter plots and regression...

By focusing on "Candium", pupils can work through this guide to learn more about different isotopes.  The teacher will supply M&M's, Skittles and Reeses Pieces to provide data about mass and abundance.
