Students develop an understanding of how aspirin works and how understanding its interaction with other chemicals in the body aided doctors in medical research.
Students devise a scientific investigation to detect acids and bases in common materials. Students will prepare a test solution whose color changes when an acid or base is added.
In this activity, students will use a chemical reaction to test for the presence of carbonate in calcite and limestone. Students will drop a small amount of acid on mineral specimens and observe the bubbles of carbon dioxide forming from the reaction of the acid with carbonite minerals.
This worksheet provides practice problems for computation of [H+] and [OH-].
Students will learn to identify and define acid and base and classify household chemicals as acids or bases using universal iindicator.
In this lab activity, students will determine the concentration of a solution of NaOH by titration with a standard solution of HCl. They will also determine the concentration of a sample of white vinegar by titration with a standard solution of NaOH.
In this lab activity, students will test the pH of a number of common substances.
This worksheet provides practice problems for computation of [H+] and [OH-].
In this animation students will learn about refraction and how sound waves influenced the outcome of several Civil War battles.
In this lesson, students work collaboratively and use art supplies to create a display of the Earth's landforms.
Students will investigate concepts related to endothermic and exothermic reactions and activiation energy. Students will construct and interpret an energy diagram showing the progress of an exothermic reaction.
This brief video lesson discusses chemical reactions in the body and how enzymes assist in the process. Discussion/assessment questions and suggested supplemental resources are also included.
This article describes covert and overt active engagement strategies for use with elementary students. Find the Question templates are included for use with informational text.
This quiz allows students to check their understanding of active transport processes.
This online tutorial covers primary and secondary active transport.
This article discusses the four forms of identifying similarities and differences: comparing, classifying, creating metaphors, and creating analogies and how these strategies can be used in an elementary classroom.
Selected resources provide three web-based activities to complement science lessons in an issue of Beyond Weather and the Water Cycle. The free, online magazine for Grades K-5 teachers explores the essential principles of climate literacy.
In this activity, students play a game that simulates the carbon cycle. During the activity students will compare the carbon cycle before and after the industrial revolution.
In this activity, students learn about different types of water erosion and develop strategies to slow down erosion where man is involved.
In this activity, students learn about different types of wind and ice erosion and explain the difference between weathering and erosion.
