If you have some innovative laboratory exercises that use or promote a problem-solving or investigative approach, and if you are willing to share, you may submit materials for posting. Click here if you want specific ideas and detailed instructions about the preparation and submission of materials. This reference includes information about HTML editors and where to obtain such programs. Just be certain to include relevant date so expired items can be purged. Unless otherwise indicated, materials are oriented to a college level.
Many materials are adaptable to various levels.
A twig key program listed under Science Lessons for Elementary Teaching can be used for ages 10-11 and up, so don't let directory categories overly limit your imagination and creativity. Do contact me if you find the materials that you seek, or if a link does not work. Many materials for posting have not yet been converted to hypertext. In many cases, plain text version exist, and attempting to access these files will display instructions for browsing and downloading the plain text file. Sorry for any disappointment.
