Classroom Resources: Chemistry Basics

51 – 60 of 60 Classroom Resources

• 

  Phase Changes, Physical Change, Observations, Temperature | Elementary School, Middle School

  Lab: Condensation

  In this lab, students will explore the process of condensation. Students will investigate how water vapor condenses, and then they will conduct a comparison test to see if cooling water vapor has an effect on the rate of condensation.

• 

  Separating Mixtures, Density, Physical Change, Chemical Change, Mixtures, Intermolecular Forces, Intermolecular Forces | Middle School

  Lab: Clean it Up!

  In this lab, students will consider and utilize various separation techniques to purify and reclaim used motor oil.

• 

  Solute & Solvent, Physical Change, Solubility | Middle School, High School

  Lab: Chemistree

  In this lab, students will prepare a solution to observe a physical change.

• 

  Chemical Change, Observations, Chemical Change, Reaction Rate, Interdisciplinary, Physical Change, Reaction Rate | Middle School

  Lab: Chemical Weathering in Geology

  In this lab, students will explore the differences between erosion, weathering and chemical weathering. They will complete a lab experiment that simulates chemical weathering on 4 different types of rocks. They will also learn how to use the Mohs Hardness Test to analyze the results.

• 

  Chemical Change, Physical Change, Observations, Chemical Change, Interdisciplinary, Acid, Chemical Change | Middle School

  Lab: Break It Down!

  In this lab, students will examine the physical and chemical changes that take place within a landfill by composting leftover fruits and vegetables from their lunches. They will also record pH and temperature measurements during the process.

• 

  Reversible Reactions, Observations, Chemical Change, Physical Change | High School

  Lab: Breath Test

  In this lab, students investigate whether chemical reactions can happen only in one direction, or whether they can be "undone."

• 

  Mixtures, Mixture, Chemical Change, Physical Change, Observations, Density, Acid Base Reactions, Chemical Change | Elementary School

  Lab: Analyzing a Lava Lamp

  In this lab, students create a mixture of oil, water and food coloring, and then add an Alka-Seltzer tablet, to create a homemade lava lamp. Student will record their observations during each step of the process and answer follow-up questions about the chemical and physical changes that took place.

• 

  Physical Change, Chemical Change, Solute & Solvent, Observations, Inferences, Physical Change, Identifying an Unknown | Elementary School

  Lesson Plan: Alien Invasion?

  In this lesson, students will explore both physical and chemical changes as they try to help the Department of Homeland Security analyze and identify materials found in a mysterious capsule. Students will examine and observe an unknown object (a frozen water balloon) as it changes (melts). They then mix combinations of everyday substances to observe chemical changes.

• 

  Physical Change | High School, Middle School

  Activity: Magic Bubble

  In this lesson, students will create and interpret particle diagrams that represent elements and compounds at the molecular level. They will also describe the process of dissolving and create particle diagrams that represent mixtures at the molecular level.

• 

  Intermolecular Forces, Polarity, Molecular Motion, Intermolecular Forces, Molecular Motion, Physical Change, Physical Change

  Simulation: Comparing Attractive Forces

  In the November 2014 issue, students explore the different attractive foreces between pairs of molecules by dragging the "star" image. In the accompanying activity, students investigate different types of intermolecular forces (London dispersion and dipole-dipole). In the analysis that follows the investigation, they relate IMFs (including hydrogen bonding) to physical properties (boiling point and solubility).
