In this lab activity, students will test household chemicals with litmus paper and using red-cabbage juice inidcator and use the results to classify household substances as acids or bases.
Using third grade Michigan Science Standards students will learn about force and motion then design, describe, and create an arcade game for others to play. Since this is a PBL, many ELA content standards are also included.
This is a remix of Caine's Arcade PBL, orginially authored by Val Capel, Katie Johnson, and Michele Randle. The original work was aligned to Michigan State Standards and housed in Google Drive, which made it difficult to remix on this platform.This version has been aligned to North Carolina State Standards and was created on this platform for easy remixing by others.
Students will investigate heat transfer by using a standard calorimeter set-up.
Students will burn a peanut to learn basic principles of calorimetry.
Students will be able to explain, on the molecular level, how a gas dissolves in water. They will also be able to explain why the gas comes out of solution faster in warm water than in cold water.
Water is a limited resource that we use over and over again. The idea is to teach the science behind the water cycle, where water comes from and is located on the Earth. After research and developing and understanding of conservation students will create a water tower that will collect and store rainwater. Students will also create a Public Service Announcement (PSA) on water conservation.
Students will place isopropyl alcohol, mineral oil and corn syrup in water to see if any of these liquids dissolve in water. Students will extend their understanding and definition of "dissolving" and see that certain, but not all liquids can dissolve in water.
This activity demonstrates the use of a catalyst in the decomposition of hydrogen peroxide.
In this activity, students are introduced to the concepts of static and kinetic friction and discover how the type of surface involved affects the strength of the frictional force.
In this activity students will investigate how different materials are changed when heated or cooled. Students will choose from a variety of materials and devise a method of data collection.
In this lesson, students learn about homogenous and heterogeneous mixtures. They will then devise a way to separate a heterogeneous mixture of salt, black pepper, and sand using the equipment available to them. This lesson begins on p. 24 of the pdf document.
In this lab activity, students will investigate chemical changes that occur when acids and bases react. It is meant to introduce the concepts of chemical changes, mass of gases, conservation of mass, and balancing equations. Students will make qualitative observations and quantitative measurements.
In this tutorial students will learn how to identify the components of a chemical equation and how to balance chemical equations.
Students will perform several experiments. For each one they will be expected to write an equation and indicate the type of reaction.
This resource is an in-depth discussion, with diagrams, covering the different types of chemical bonding. It details ionic bonds, covalent bonds, polar covalence, and electronegativity.
In this lab activity, students will investigate the characteristics of a chemical change. Students will also provide a definition of what constitutes a physical change through observation of several examples. Students will develop (through discussion) and use the criteria for identifying a chemical change. Several examples of a chemical change will also be observed for students to compare to physical changes. The students will use the five characteristics of chemical change to determine/judge whether or not baking soda, citric acid and water creates a chemical change. Students will write down observations of the reaction and use the five characteristics to explain why it is in fact a chemical reaction (The five characteristics will be listed for use).
This interactive resource includes 10 equations for students to practice balancing equations.
This short interactive tutorial provides students practice in balancing chemical equations.
In this interactive students will learn chemistry concepts by discovering how "Croda" products transform the bathroom from a disarray to a fully functional clean bathroom. There are articles attached for students to review about various topics.
