How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?

In this section we will be talking about the basics of acids and bases and how acid-base chemistry is related to chemical equilibrium. We will cover acid and base definitions, pH, acid-base equilibria, acid-base properties of salts, and the pH of salt solutions.

Conducting Scientific Research to Support a Claim
Conditions of Use:

How can we conduct scientific research so that we have evidence to support a claim?Students in this problem-based learning module are invited to design a testable question to guide Scientific Research, Evaluate the pH of various solutions, Identify Variables, Conduct a Scientific Investigation, and Analyze/Communicate results.    How can we conduct scientific research so that we have evidence to support a claim? Antacid tablets are a multi-billion dollar industry.  Claims are made regularly by certain brands that their extra strength tablets contain “DOUBLE the acid neutralizing power per tablet of regular strength antacids.”  How effective are antacids?  Are double-strength antacids twice as effective as regular strength antacids?  Have you ever noticed a parent/guardian/family member take an antacid tablet? Stomach chemistry is about acids and bases.  When the pH of a stomach is too acidic then it might make the person have a stomach ache.  In some cases “heartburn” or “acid reflux” are used as terms to describe the problems some people face.  Antacids are usually basic which, when taken, might help raise the pH level in a stomach thus making a person feel better.You are invited to design an investigation with a partner, or a team of 4 students, to test your own idea about the effectiveness of antacids.  The challenge?  Have a driving question, clear variable identification, and an analysis of your results.  Materials for your test will be provided to you by your teacher.  At the culmination of your investigation your design team will make a 30-second pitch on your phone to show at your family Thanksgiving meal to explain the benefits (or negatives) of using antacids, and how antacids work.

Engineering Out of Harry Situations: The Science Behind Harry Potter
Conditions of Use:

Rating

Under the "The Science Behind Harry Potter" theme, a succession of diverse complex scientific topics are presented to students through direct immersive interaction. Student interest is piqued by the incorporation of popular culture into the classroom via a series of interactive, hands-on Harry Potter/movie-themed lessons and activities. They learn about the basics of acid/base chemistry (invisible ink), genetics and trait prediction (parseltongue trait in families), and force and projectile motion (motion of the thrown remembrall). In each lesson and activity, students are also made aware of the engineering connections to these fields of scientific study.

Inorganic chemistry is a division of chemistry that studies metals, their compounds, and their reactivity. Metal atoms can be bound to other metal atoms in alloys or metal clusters, to nonmetal elements in crystalline rocks, or to small organic molecules, such as a cyclopentadienyl anion in ferrocene. These metal atoms can also be part of large biological molecules, as in the case of iron in hemoglobin (oxygen-carrier protein in the blood). Upon successful completion of this course, students will be able to: Describe nuclear charge and calculate effective nuclear charge in terms of Slater's rules; Demonstrate an understanding of trends in the periodic table; Describe the bonding between atoms in terms of valence bond theory; Describe inorganic structures by using valence shell electron pair repulsion theory; Identify the nomenclature rules of coordination compounds; Demonstrate an understanding of crystal structures, lattice energies, and different types of unit cells; Explain the electronic structure of solids, the concept of band gap energy, and how this band gap determines the electronic properties (insulator, conductor, and semiconductor) of solid materials; Describe general trends in the reactivity of elements within Groups I through VII.

This unit helps you understand the properties of nucleotides and how they contribute to secondary and tertiary structures of nucleic acids at the molecular level. You will learn about the different composition and roles of nucleic acids in the cell, their interactions with each other and the use of ribozymes, aptamers, antisense and hybridization as tools in molecular research. The unit covers the function of DNA packaging within the cell, the interactions between the DNA double helix and the nucleosome and it helps you understand the various chromatin states within the interphase nucleus.

Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!
