This activity combines field and classroom investigations about snowflakes to develop a testable question.

In this activity students investigate soil pH differences and buffering capacity as it relates to acid rain, interpret and present their findings, and develop a new, experimental question.

This activity is a classroom investigation where student observe several properties of water; adhesion and cohesion. They will transfer this knowledge to predicting other materials that will have adhesion with water molecules.

In this video segment adapted from ZOOM, the cast builds a suspension bridge from a couple of chairs, some cardboard, and rope.

This activity is a classroom lab where students test common household liquids for pH level on the pH continuum, 1-14. They compare and contrast everyday use of the liquids, and how this relates to the liquids' pH property.

This activity is an inquiry investigation where students gather data on why the Cartesian diver sinks or floats. They then develop a new question and then conduct a new investigation by changing one variable and repeat the altered experiment and record their conclusions.

In this activity students collect snow in a cup, predict how much water will be in the cup when the snow melts. Students are exposed to evaporation as the water "disappears" over time and try to stop this from happening.

This activity is a chemistry lab-based investigation where students apply observational skills and critical thinking skills to finding specific heat and heat capacity using different temperatures of water and solids. A final activity will assess students understanding of specific heat and heat capacity and promote data analysis skills, using real-life situations.

This activity will give kindergartner the chance to see what happend when they paint an iodine solution over a lemon juice message. They get to make thier own invisible message!

In this interactive activity from ChemThink, learn how ionic bonds are formed and how an ionic bond structure is represented by its formula.

This is a POGIL activity geared for general chemistry students. The activity guides students through the process of determining how ionic and binary compounds are named as well as inorganic acids.

This activity lends itself well to the review and repetition of previous topics and skills. The multi-faceted learning (and display of learning) is an excellent manner of getting the students to think about what they are doing and how they are answering.

This activity is a mini-lab where students determine a procedure they might use to prove that air is matter.

This lab helps students to understand the density is state dependent and can change based on the state of the element.

Spreadsheets Across Curriculum module/Introductory chemistry course. Students build spreadsheets to examine unit conversions between the metric and English systems. Spreadsheet level: Beginner.

In this video segment adapted from NOVA scienceNOW, follow scientists in their quest to understand how stable elements are made and how to create the elusive element 114.

This site explores the classification of igneous rocks. Content addresses classification based on color and texture, mineral composition, and chemical composition.

This site from the Nobel eMuseum of the Nobel Foundation provides an excellent overview of Johannes van der Waals. This detailed biography covers all aspects of his life, with a particular emphasis on his scientific achievements.

John Polanyi, 1986 Nobel Laureate in Chemistry, published this essay in 2000. In it, he discusses threats to democracy in the form of weapons, and how scientists today must remember their higher purpose, and use their technical expertise and status to support democracy everywhere.

Through two lessons and five activities, students explore the structure and function of cell membranes. Specific transport functions, including active and passive transport, are presented. In the legacy cycle tradition, students are motivated with a Grand Challenge question. As they study the ingress and egress of particles through membranes, students learn about quantum dots and biotechnology through the concept of intracellular engineering.
