We have been using PLATO middle school science (Earth and life) for several months now with my finishing 5th and 3rd graders (she's quite accelerated). We all love it! The kids are engaged, learning tons, and NEVER complain - even though I make them outline the lessons before taking the Mastery tests, and "require" 90% on tests rather than the 80% considered mastery. Its a clear winner here!

I love the fact that it is rigorous, solid science (I am a physician), engages the kids without being full of games, bells and whistles, and that t...(more)

My daughter has become interested and knowledgeable in chemistry thanks to Plato Science. It allowed her to learn at her own pace and stretch her mind. Not being well versed in science, I could not have taught this subject to her. I am glad you offered this science program at a price we could afford. We are definitely considering using Plato Science in the future.

Thanks for offering so many options to homeschoolers.

My girls look forward to Plato. It is a secular science program. However, we feel it is so well-done and enjoyable that we "tune-out" the billions of years ago statements. Plato gets an A+! We conquer the mastery tests online and then we do the paper tests. It's challenging and yet very palatable. It keeps my girls' attention who need to learn using the auditory senses. It's a superior science program.
Pam S., Co-op Member
As homeschoolers we are so pleased with the quality, flexibility and format of the Plato Life Science course. The tests give me measurable results for learning while we can learn at the pace that is comfortable for my student. We plan on using other Plato science courses in the future.
Michelle B., Co-op Member
We have really enjoyed Plato science. The colorful and detailed illustrations help make the lessons fun. I appreciate that the lessons are linear and not too busy. Although much of the vocabulary is new, the lesson uses the terms frequently, with illustration, and in context so that the words soon become familiar. As a busy mom, I like this curriculum much better than unstructured resources no matter how complete. I expect that we will continue to use Plato Science as long as I continue to homeschool.
D. Dayley, Co-op Member
We give homeschooling to our children and PLATO-Leaning is a success story. Our oldest son who is in 9th grade is using the curriculum of PLATO-Physics. He is learning with enthusiasm and at his own pace. We will definitely continue to use PLATO-Leaning.
Ivonne D., Co-op Member
At my house, we love PLATO. My son, only starting 5th grade, but excelling in science, is able to work independently on his science without becoming the slightest bit distracted (an amazing feat). The format is phenomenal with its interactive lessons and follow up tests. He rarely had to repeat a lesson (less than 85%-my standard for him). That's a huge testiment to the presentation style. Further, he completed all the sciences available (except chemistry) within a year's time. Not praise for my son (although very good) but rather: a program th...(more)

Linda B.,
I love it! My 12 year old son is using the astromony portion of Earth Science and Space while my 14 and 16 year olds are using biology! I just today found the teacher's area and the quizes and tests are wonderful! I also like the worksheets although they are too long and detailed to print. I am using apologia books and have interspersed the PLATO. It will be interesting to see which they prefer and which they learn more and easier from! They are enjoying the activities also. I also purchased Life Science and now just need to find time to ...(more)

We have enjoyed using PLATO Life Science during our first year of homeschooling. We plan to complete Earth and Physical Science this year. It kept my electronically-inclined son quite engaged with its vivid and entertaining lectures. I appreciated its thorough content and mastery tests. I have recommended it to other homeschooling families.
Desiree D., Co-op Member
My daughter used PLATO science programs for middle school science through an online program. We wanted a substantial high school science program and looked to see if PLATO did high school science as well, but were disappointed to find out that Edmentum does not sell to individuals. So I was really happy to find that we were able to get PLATO through Homeschool Buyers Co-Op. My daughter loves science so I got the "unlimited" package -- she's been really happy to be able to open all the high school science courses at the same time.
Barbara W, Co-op Member
I have had so much difficulty finding a good science program that would give my kids a solid science background. Plato has impressed me so far. The videos are engaging and well put together. The worksheets, applications and tests are thorough and well done. My high school aged son has enjoyed it and is constantly explaining to me the concepts he has been learning about in the lessons. I now plan to use Plato science courses for junior high and high school for all my kids. I am so glad I don't have to grade everything (some worksheets require ...(more)

This year my son is using PLATO Physics. He finds it very user-friendly. The site is easy to navigate, the lessons are an appropriate length, the material is clearly stated. Because we are paying one price per month for access to Physics, Chemistry, Biology and Earth Science, my son is taking advantage of this and going back to review Chemistry. We will use PLATO for my other son for high school. Wish I had tried it sooner.
