Adapting the song "A-Hunting We Will Go," students put a "whale" in a "pail" and even "take a little "bear" and hug it if we "dare"."

The standard citation style guide book for the fields of business, education, health science, public service, and social science is the Publication Manual of the American Psychological Association, 6th edition, 2010. The American Psychological Association (APA) publishes the manual. We commonly refer to it as "the APA Manual".

The business, education, health science, public service, and social science departments at IRSC recommend APA format for papers written in these fields.

Two types of citations are included in most research papers: citations within the text of the document and a list of reference citations at the end of the paper.

In-Text Citations:

The APA Manual uses the author-date citation system for in-text citations.

Reference Citations:

The sources you use in your work are included as a separate list at the end of the paper. The APA Manual suggests using the title, References, for the list.

Created by NHPRC Teacher Participant/Creator David Richman for his AP World History course. Adaptable to US History. Adaptable to other grades. Assignments ask students research the effects Executive Order 9066 had on families of Japanese descent, to analyze primary sources, and to create an illustrated story book detailing Ms. Wakatsuki’s time spent at Manzanar, a Japanese internment camp.

Podcasting can be a great way to get students, parents, and community members involved with classroom activities and information. ELL students can use podcasting as a way to demonstrate the skills they are developing as well as provide a way to reach other ELL students who may be encountering similar (difficulties).

Direct teaching of vocabulary can help improve comprehension only when taught in meaningful context. Through the use of technology, students can develop their academic vocabulary in an engaging and fun way.

An interactive applet and associated web page that shows how triangles that have two angles and their included side the same must be congruent. The applet shows two triangles, one of which can be reshaped by dragging any vertex. The other changes to remain congruent to it and the two angles and the included side are outlined in bold to show they are the same measure and are the elements being used to prove congruence. The web page describes all this and has links to other related pages. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

You will present students with a challenge: build a structure from different materials that will protect a model of the Ares launch vehicles (a raw egg) from the heat of a propane torch for as long as possible. Then they design, build, test, and revise their own thermal protection systems. They document their designs with sketches and written descriptions. As a culmination, students compile their results into a poster and present them to the class.

This activity explores the concepts of energy transfer with the following standards:
• Energy is a property of many substances and is associated with heat and light.
• Heat moves in predictable ways, flowing from warmer objects to cooler ones, until both reach the same temperature.

This activity focuses on getting the students to think about disabilities and how they can make some aspects of life more difficult. The students are asked to pick a disability and design a new kind of sport for it.

Aboriginal Hand Print
(art + history; art + social studies)
"One old man in Arnhem Land remembered being carried as a child on his father's shoulders as his father climbed up a log leaning against a rock wall. His father then sprayed his hand with red ochre against the rock, leaving a stencil he could still recognize many years later. The main function of the stencils was to record people's presence and association with a site." — Aboriginal Art Online

The stenciled hand print and aboriginal style drawings help children to relate to the man from the Australian Aboriginal Culture stated above, while helping them to understand the use of line in art. A black paper with white splattered paint was used, but white paper with red (ochre) splattered paint would make a nice impression also. Construction paper crayons make bright, bold, linear designs around the hand stencil.

Grade Levels K-4

This problem involves solving a system of algebraic equations from a context: depending how the problem is interpreted, there may be one equation or two.

In this activity, students explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also learn several things that engineers are doing to reduce the effects of acid rain.

How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?

This activity is acid-base titration lab where students determine the percent of calcium carbonate in an eggshell.

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.

In this project, each student will be assigned to a group of three to four students. Each group will be given random character description cards. These characters will be treated as the first generation in a fictitious town. The cards will include specific genetic traits, skills, jobs, as well as reference if the character suffers from type 2 diabetes. Students will need to use the character cards to author and illustrate a short story about the fictitious town which follows at least three generations of the families in the cards. Students must also include pedigrees for a minimum of three traits as well as diabetes as evidence of inheritance.

How can you use the Engineering Design Process to access a geographically inaccessible location to deliver supplies?

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

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 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.
