Classroom Resources: Chemistry Basics
76 – 90 of 90 Classroom Resources
-
Indicators, Chemical Properties, Observations, Acid Base Reactions | Elementary School
Lab: Can a Cabbage Distinguish an Acid from a Base?
In this lab, students will first determine what colors the cabbage indicator turns in acidic, neutral, and basic solutions.
-
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."
-
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.
-
Polymers, Physical Properties, Introduction, Observations | Elementary School
Activity: Bouncy Ball
In this activity, students explore the chemical reaction between borax and glue, creating a polymer ball. The properties of the polymer ball will be analyzed and compared to a store bought bouncy ball.
-
Inferences, Observations, Scientific Method | Middle School, High School
Activity: Black Box
In this activity, students will experience how scientists carry out a scientific investigation through inquiry.
-
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.
-
Chemical Change, Classification of Reactions, Oxidation, Reduction, Redox Reaction, Electrons, Electron Transfer, Ions, Observations, Inferences, Chemical Change | Middle School
Lesson Plan: One Tube Reaction
In this lesson, students will observe a chemical change involving oxidation and reduction.
-
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.
-
Observations, Scientific Method, Experimental design, Error analysis | High School
Lab: Airplanes
In this lab, students will design a procedure to test for the intended outcome of a longest flight.
-
Chemical Change, Observations, Exothermic & Endothermic, Temperature, Chemical Change | High School
Lab: Observing a Chemical Reaction
In this lab, students will practice making careful observations and measurements while witnessing a chemical change.
-
Observations, Combustion, Phase Changes | High School
Lab: Observing a Candle
In this lab, students accumulate observations of a candle including a look at the combustion reaction's reactants and products.
-
Observations, Inferences, Scientific Method | High School
Demonstration: Observations vs. Inferences
In this demonstration, students will learn the the difference between observation and inferences.
-
Redox Reaction, History, Oxidation, Reduction, Chemical Change, Observations | High School
Demonstration: Nitric Acid Acts Upon Copper
In this demonstration, students will hear a story about Ira Remsen and watch a demonstration that recreates her first experiment reacting nitric acid with a copper penny.
-
Chemical Change, Chemical Change, Observations, Acid, Chemical Change | Elementary School
Lab: My Pennies
In this lab, students will investigate how an acidic, vinegar based solution can help to get “dirty” pennies clean. Students will observe chemical change and investigate real-world connections to this lab.
-
Chemical Change, Observations, Mixture, Acids & Bases, Chemical Change | Elementary School, Middle School, High School
Demonstration: Inflating a Balloon with Chemistry
In this demonstration, the teacher will perform a reaction between acetic acid (vinegar) and sodium bicarbonate (baking soda) in order to inflate a balloon and to introduce the concept of a chemical reaction to students. Students will observe the reaction, and identify indicators of chemical change as well as discuss the different types of matter that are involved.
