A comprehensive practice exam, this resource covers many areas of chemistry. The test includes 71 multiple choice questions on topics such as problem solving, chemical equations, chemical formulas, thermodynamics, acids and bases, and...

Use this resource to present your number crunchers with how to write a constraint equation and to determine viable solutions. The price of an object limits the amount that can be purchased. The speed at which you walk limits the number...

What's the difference between a rock and a mineral? And what properties are used to identify minerals? The first installment of a five-part series on earth materials and processes prompts young scientists to identify a set of...

Need to prep your science learners in math? Here is a resource that serves as a review guide to support your scientists with the math they need to be successful in chemistry. Comes with basic algebraic problems and a review of...

Learn how ocean currents are vital to humans and marine life. The eighth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program, focuses on ocean currents and how they affect global climate. The...

Learners engage in six activities to lead them through the process of conducting a thorough analysis of data. Pupils work with calculating standard deviations and z-scores, finding the area under a normal curve, and sampling...

Graphs, functions, symbols, and more! Use these strategies to model everything from the flow of a river to the number of cars passing a toll booth. Presented differently but solved similarly, learners consider five different scenarios...

A fascinating lesson on states of matter is here for your young scientists. Dry ice is used to challenge learners preconceived notions about how solids work. They discover all sorts of interesting facts about states of matter from...

Students observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water

Eureka! Using the clay boats made in the previous lesson, learners investigate the idea of buoyancy and water displacement to finish the last installment of five in a Floaters and Sinkers unit. Their observations during the activity...

First graders discuss and predict if a given object sinks or floats. They record their predictions on a data sheet. Pupils test the objects and organize them into floating/sinking groups. Students observe the floating and sinking of a...

Second graders identify the three states of matter by examining fishbowls with various contents. They discuss their observations and the characteristics of matter in each state. Pupils read the story The Rainbow Fish and look for...

Students examine the built environment and infrastructures of their community by constructing contour equipment, using the equipment, and comparing their results to current topographical maps of the same area

Students review the units of the metric system, and practice estimating measures before actually converting between the two systems of measurement. They participate in activities to visualize a concentration of one part per million....

Sixth graders investigate the livability of different planets in the universe by researching and organizing information from a number of sources in this unit project. They decide on a location for a space station which they support in an...

Young scholars are introduced to the forces that are responsible for generating waves in the ocean and how these forcesf differ from those that cause currents. They are able to explain how water molecules in a wave do not move in the...

Ecology aces examine sea surface temperature maps and relate temperatures to concentration in fish and zooplankton populations. Take your class to a computer lab and provide experience with actual remote sensing data. Some of the links...

Student teams use a digital camcorder and iMovie to create a commercial about an element. They also use the Internet and their textbook to gather the following information about their element: the name, the symbol, the atomic number, the...

In this metric units and properties activity, students determine the proper metric unit given a variety of measurements for specific items. They also identify chemical and physical properties and chemical and physical changes.

In this molality and colligative properties worksheet, students determine the molality of solutions and they calculate freezing point depressions and boiling point elevations of solutions.

In this ideal gas law worksheet, learners solve eighteen problems using the ideal gas law to solve for moles of gases, temperature of gases, pressure of gases or volumes of gases.

Compare various types of biological diversity in a coral reef and calculate a numeric indicator that describes the diversity found in coral communities. Your class can work in groups to look at the abundance and distribution data of...

High schoolers solve five problems including finding the cross sectional area of two bodies, determining the swept out volume of a moving body, finding the average particle volume of a body and determining the collision time for a body.

Students use optimization concepts to design their own container. For this optimization lesson plan, students understand how the optimization concept is critical in calculus and why products are packaged the way they are.
