Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them.

In this video segment, the ZOOM cast demonstrates how to use cabbage juice to find out if a solution is an acid or a base.

In this video segment adapted from ZOOM, two cast members demonstrate what happens when vinegar is added to baking soda inside a container. The resulting chemical reaction produces enough carbon dioxide to launch their paper rocket skyward.
Recommended for: Grades K-5

A car propelled by the reaction between lemon juice and baking soda has more in common with rockets and jet aircraft than one might think. In this video segment adapted from ZOOM, two cast members demonstrate the power of rocket-propelled vehicles and how to exploit the force produced by the carbon dioxide gas. Grades 3-8.

It would seem that bottles of lemon juice and rockets have only their basic shape in common. However, as two cast members from ZOOM demonstrate in this adapted video segment, when baking soda is added to the mix, a plastic bottle can act very much like a real rocket. Grades 3-8.

In this section we will be talking about the basics of acids and bases and how acid-base chemistry is related to chemical equilibrium. We will cover acid and base definitions, pH, acid-base equilibria, acid-base properties of salts, and the pH of salt solutions.

Students play and record the “Mary Had a Little Lamb” song using musical instruments and analyze the intensity of the sound using free audio editing and recording software. Then they use hollow Styrofoam half-spheres as acoustic mirrors (devices that reflect and focus sound), determine the radius of curvature of the mirror and calculate its focal length. Students place a microphone at the acoustic mirror focal point, re-record their songs, and compare the sound intensity on plot spectrums generated from their recordings both with and without the acoustic mirrors. A worksheet and KWL chart are provided.

This lesson employs direct instruction and small-group discussion to help students learn new vocabulary skills while reading Patricia Polacco's "Pink and Say".

This online tool enables students to learn about and write acrostic poems. Elements of the writing process are also included.

Students create acrostic poems using their names and the names of things that are important to them.

Creating an illustrated alphabet book of action words, from "attack" to "zap", reinforces the definition of verbs as it stretches and expands students' vocabulary.

Students must "become" a character in a novel in order to describe themselves and other characters using powerful adjectives.

Students construct rockets from balloons propelled along a guide string. They use this model to learn about Newton's three laws of motion, examining the effect of different forces on the motion of the rocket.

This lesson is based on the Annenberg Classroom video âA Call to Act: Ledbetter v. Goodyear Tire and Rubber Co.,â which tells the law-changing story behind the Lilly Ledbetter Fair Pay Act of 2009. Students gain insight into law-making process, consider how statutory decisions made by the Supreme Court can prompt better laws, and learn about the rights and responsibilities they will have when they enter the workforce.

The estimated time for this lesson is four days.

Students should have a solid foundation of the regional differences in the former colonies, now states, as well as an understanding of the ratification of the Constitution. This Lesson is best used after students have read The Constitutional Convention and The Ratification Debate on the Constitution Narratives in Chapter 3. The James Madison and the Bill of Rights Narrative in Chapter 4 can be used as background for the Lesson or can be assigned as homework after the Lesson to reinforce main ideas.
