This is an introductory physics lab where students will review scientific measurement concepts, and then develop a procedure, in which they will use the concepts of proper precision in measurement and significant figures, to determine the density of a marble.

This activity is a lab investigation where students collect and analyze data on towers built with various components and compare the two.

This laboratory activity demonstrates how seismic waves are generated and helps students understand how they can reveal the composition of Earth's inner layers. Students will construct models by filling shoe boxes with various materials, drop rocks on them to generate 'seismic waves', record the waves, and make observations about their differences.

Dope the semiconductor to create a diode. Watch the electrons change position and energy.

Students learn how to classify materials as mixtures, elements or compounds and identify the properties of each type. The concept of separation of mixtures is also introduced since nearly every element or compound is found naturally in an impure state such as a mixture of two or more substances, and it is common that chemical engineers use separation techniques to separate mixtures into their individual components. For example, the separation of crude oil into purified hydrocarbons such as natural gas, gasoline, diesel, jet fuel and/or lubricants.

This lab is a two part investigation on separating a solid from a liquid where students are asked to develop their own investigable question and carry out the experiment on day two.

Module outline and learning resources for H81SPF Separation Process Fundamentals.

The module aims to introduce basic principles and concepts behind basic unit operations used in chemical and environmental processes and applications. The module enables understanding so that students are able to apply separation processes in given applications and use appropriate calculation techniques to size process equipment.

Students learn about STEM education through an engineering design challenge that focuses on improving building materials used in shantytowns. First, they consider the factors that lead to shantytown development. After researching the implications of living in shantytowns, students design, build and test cement-based concrete block composites made of discarded and/or recycled materials. The aim is to make a material that is resistant to degradation by chemicals or climate, can withstand natural disasters, and endure through human-made conditions (such as urban overcrowding or pollution). The composites must be made of materials that are inexpensive and readily available so that they are viable alternative in shantytown communities. Students assess the results both chemically and physically and then iterate their designs with the materials that proved to be strongest.

This chemistry lesson uses Sharpie Markers, rubbing alcohol and t-shirts to make a exciting tie-die looking t-shirt

This article, written for students in grades 4-5, introduces the concept of albedo and describes the shrinking of Arctic sea ice. Modified versions are available for students in younger grades.

In this decision-making exercise, students investigate what would occur if a dam were built along Nanticoke Creek, a real stream just north of West Corners near the Village of Endicott, New York. They will use topographic maps to determine how much area would be flooded by the new reservoir, to study river drainages, and to consider the impacts of dams on a region. They must also consider rivers in the context of their relation to humankind. The exercise can be extended to other, more local locations having similar topography.

In this adapted ZOOM video segment, cast members calculate how much water they each use during a typical shower. They compare their results to their original predictions.

This activity is a hands-on activity where students learn about polymers and the science of plastics, while making shrinky dinks.

This module is an introduction to Accuracy, Precision, and Sig figs.  It includes how to count the number of significant digits and defining accuracy versus precision.  

In this module we will be exploring the idea of Significant Figures. At the end of the module you should be able to...1. Determine the number of significant figures in a given number. 2. Determine the number of significant figures your answer should have after basic math functions. (Add, subtract, multiple, and divide) Corresponding OpenStax Textbook Section 1.5Significant Figures

Student teams make polymers using ordinary household supplies (glue, borax, water). They experiment with the semi-solid material when warm and cold to see and feel its elastic and viscous properties. Students will begin to understand how the electrical forces between particles change as temperature or the force applied to the substance changes. Is it a solid, a liquid, or something in between? How might it be used?

In this activity, students investigate convection as it applies to Earth processes. They will assemble a model using a bread pan to view convection in two paired cells. They will also investigate the strengths and weaknesses of the model thay have constructed and answer some questions about what they are seeing.

In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts. Escapements are found in mechanical clocks, such as those driven by a pendulum or a spring. Learners will build the wrapping form of escapement said to be used in a fifteenth-century German clock.

This video segment from IdahoPTV's D4K lists, describes and shows examples of the 6 simple machines and how they make work easier.

In this activity, learners create a tiny electric, motorized dancer. Learners use the interactions of magnetism and electric current to make a wire spin, while displaying the Lorentz Force in action. This lesson guide provides one of many ways to build the spinner and links to other methods.
