Element Experts -Group Project
Element Experts in Team:
________________________________________________________
This project requires each student in your group to become an “Element Expert” on the
element assigned to you. After learning all about your element and completing your
Element Experts Square and informational essay, student groups will combine element
information to create a group PowerPoint showcasing each element and the unique
features of the family your group of elements represents.

Element Experts -Group Wiki and PowerPoint
There are 7 sections to this PowerPoint. The PowerPoint includes a title slide, a Family
information slide, four Element slides and a Reference slide. (See Grading Rubric)
Each student in the group gets one slide on the PowerPoint that focuses on their
element. Each element slide is required to have 2 graphics. (See Element Requirements
Sheet) All the information from the element information sheet must be on the element
slide.
POWERPOINT PRESENTATION –
Must have at least 7 slides (no more than 10)
All requirements for the Element Square should be included in your PowerPoint
presentation. (Provide detail and elaborate on each item)
Make good use of graphics and animation (Note: too many sounds or special
effects can be distracting to the audience.)
Make sure your Internet search includes appropriate sites. (5 references
minimum. See Grading Rubric)
When presenting, be sure to speak toward the audience.
Talk loud enough for the people in the back of the room to hear you.
Share equal time. All group members must contribute equally – each student talks
about their own slide information. Decide who want to read the title slide and the
family information slide.
Your presentation should be between at least 2 minutes in length. (No more than
4 min.)
Be an expert on your element and be able to answer questions after the
presentation.
CLASS WIKI Go to: http://teamrscience.pbworks.com/TEAM-R-SCIENCE
On our class wiki pages, you can write about your research and store files of images,
music and PowerPoint slides. All the information the group collects will be ready to go
into presentations! You can work from home or the homework club to organize and edit
your group’s research and assignments. Collaborate with your group members to compile
your PowerPoint slides together by uploading your slide after you have logged on with
your username and password. Your teacher will assign you a wiki role from the chart
