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?

Conducting Scientific Research to Support a Claim

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.

Rating
0.0 stars

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.

In this course, we will explore what makes things in the world the way they are and why, to understand the science and consider the engineering. We learn not only why the physical world behaves the way it does, but also how to think with chemical intuition, which can’t be gained simply by observing the macroscopic world.
This 2018 version of 3.091 by Jeffrey Grossman and the 2010 OCW version by Don Sadoway cover similar topics and both provide complete learning materials. This 2018 version also includes Jeffrey Grossman’s innovative Goodie Bags, Why This Matters, and CHEMATLAS content, as well as additional practice problems, quizzes, and exams.

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.

Rating
0.0 stars

This guided inquiry learning activity is designed to be used in a large introductory chemistry course. By working in small groups to discuss the presented information and question prompts, students will engage in cycles of exploring and analyzing data, inventing new conceptual understandings, and applying those concepts. Students should be tasked with working together to complete the prompts in each section by a set time limit. After each section is completed, the entire class can share their answers via a personal response system, and the instructor can review and explain the correct responses, using the accompanying slide deck, which translates the problems into multiple-choice prompts.Instructional resources include 1) the learning activity (.docx and .pdf) 2) the learning objects (.docx and .pdf) and 3) the slide deck (.pptx).- Atomic Orbitals- Chemical Fuels- Gas Laws- Intermolecular Forces- pKa Trends- VSEPR

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!
