HippoCampus is not a credit-granting organization, and does not monitor, grade, or give transcripts to anyone using the site. However, many home schooling families have used HippoCampus content to supplement or guide their home curriculum, and we welcome them as users.

Yes, although homeschoolers should realize that the content presented is not a complete course. The content is intended to have an instructor to provide supplemental assignments and instruction. Since there is no teacher available through HippoCampus, the parent must take the role of instructor. We have done research to identify some very good wet lab resources for virtual schools that could also be used successfully by homeschoolers.

Here are a few of the options: Full sets of labs labs per course are offered for a fee. These kits are used with web courses, telecommunication courses, home-schooling programs, and all other forms of independent study. Students are not required to log in to HippoCampus. Our Terms of Use specify that HippoCampus is provided by the Monterey Institute for Technology and Education for personal enrichment and individual instructor use only.

The unlicensed use of this content by educational organizations or commercial vendors is prohibited. Unfortunately, there is no way to download the video from our website. As an individual user, however, you may create a custom HippoCampus page and then link to an individual topic. After you have created your custom page, there will be buttons in the upper right corner that allow you to view the text version when available , bookmark, or link to the topic. Yes, in multiple ways.

First, there is a "maximize" button beneath the bottom left corner of the Media Window which will widen the screen. There is also a "hide column" button beneath the first column of content in the Browse Topics tab.

These can be used simultaneously or independently. For some content, such as that from Khan Academy, a small button in the lower right corner of the media control bar allows the content to be shown full screen. For other content, such as Algebra I--An Open Course, right-clicking the mouse over the video content will open a menu that offers Full Screen as an option.

This problem occurs if you are using version 7. To fix the problem, go into the QuickTime "Preferences. Your screen resolution may be set too low. The Algebra course requires that your screen resolution be at x or higher. Most of the other content requires a resolution of x or higher.

All the content we provide at HippoCampus is created by other educational institutions and contributed to us to distribute as part of our non-profit mission. Due to the complexity of modifying the multimedia content, we cannot always correct errors within the video presentations.

There is an Errata icon that appears with any topics in which a known error has been identified. We encourage our users to report any errors they discover so that we can notify everyone of the problem.

There is also an errata sheet available for some courses if you select "Launch a Full Course. Use the "Comments and Questions" feature in the Media Window control bar. The icon looks like a small speech bubble, and allows you to send in a description of the error directly from the relevant piece of media.

Or you can send an email to Help HippoCampus. Please describe the issue as precisely as possible. If you provide your email address, we will inform you about the correction process, or ask any follow-up question necessary to clarify the report.

The tests that appear on our website are intended as open tests for self-assessment only. They are not intended to be secure tests since the answers are freely available at several websites. There are answer keys available for the chapter tests but not for the review questions. The answer keys for the chapter tests are located as a link right under the chapter test link. This is a problem that was in the original content we received from the course developer.

We have no way of fixing this at this time. The Environmental Science labs require you to have Java installed on your computer. You can get the latest version at http: We know a lot of homeschoolers use HippoCampus. We are often asked if homeschoolers can study the content at HippoCampus and then just take and pass the AP exam. However, as with any teaching resource, they should not be considered a singular solution, but can be used as a good foundation for an AP teaching curriculum. If you wish to receive college credit for taking an AP course, most colleges will require that the course have been approved by the College Board.

Schools wishing to give their students AP credit must go through the AP audit process. The same is true for homeschoolers. The AP Course Ledger section below gives more information about the audit process.

The Ledger is an annual and culminating product of the AP Course Audit, a process by which college faculty confirm that courses submitted by AP teachers and schools provide students with the essential elements of a college level experience.

As an exclusively Web-based registry, the Ledger is published annually in November and updated weekly throughout the academic year to reflect newly authorized courses. Here is a link to AP Audit information, and you can find other links on this page to various other resources: Yes, the AP Course Audit is only required for schools desiring to: Our AP content is a good resource to help students prepare for AP exams.

However, while we provide content resources, we do not have instructors who teach the courses. In order to be authorized by the College Board and put in the AP Course Ledger, an instructor must submit a syllabus for the course.

While we do not have instructors who teach our courses, we do have NROC member schools that teach the courses for credit and they have been approved through the AP College Board. Box Marina, CA NROC members cooperate to develop and share digital resources and tools to impact college and career success.
