In this ZOOM video segment, cast members make bottle rocket cars using lemon juice and baking soda, and experiment with different ways of launching the cars. [4:46]
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.
What happens when you mix baking soda and lemon juice? Watch the ZOOM cast launch a rocket using kitchen chemistry. [3:26]
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.
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
In this video, effective for engaging students with significant cognitive disabilities, watch how the teacher acknowledges the student's communication attempt.
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 teaches elementary students new vocabulary terms through book discussion groups. Students use context clues, prior knowledge, and print and online resources for vocabulary understanding in their discussion.

Students must "become" a character in a novel in order to describe themselves and other characters using powerful adjectives.
Students learn to use manipulatives and calculators to explore what happens when they change one number at a time in an addition number sentence. They record and develop the pattern that develops.
This interactive explores how neurons communicate using action potentials.
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.
Students make rockets that travel along a string.
This tutorial focuses on active listening including what it is and how to become an active listener; a slide show provides the five basic elements of listening. It also offers a video of Alice Walker reading Soujourner Truth's "Ain't I a Woman" [3:13] for students to use to practice active listening. It ends with ways to improve listening skills.

This recurring lesson encourages students to comprehend their reading through inquiry and collaboration. They choose important quotations from the text and work in groups to formulate "quiz" questions that their peers will answer.
In this activity, students watch a short clip from the ASHP documentary 1877: The Grand Army of Starvationto learn about the impact of railroad expansion on Americans and the nation as a whole. After watching the clip, students complete the “Technological Turning Points and their Impact” worksheet in order to examine the positive and negative effects of the railroad.
