Wonderful program! We are a science family. Dad is a PhD organic chemist. Our 13 year old who loves science is doing very well with it independently - great for both mom and student. I struggled to find something appropriate for his age that would still be challenging since he knows so much, and this hit the mark perfectly! He loves his science time and of his own initiative enjoys teaching me in detail what he's learned when we're in the car. That shows me he's really absorbing the information, and that Plato's doing a great job explaini...(more)

PLATO is the best homeschool curriculum my daughter and I have ever used! I tell everyone about it. The coursework is so engaging and easy to use. All of the coursework can be done at a pace that works for the student, and for my daughter who lives with the challenges of Autism, this makes a world of difference. The wonderful visuals make learning (and teaching) so much easier and so much more fun! And I find that my daughter retains so much more. Please don't ever stop carrying PLATO, it's the most affordable, effective program we've eve...(more)

The earth science course was fantastic. I have been recommending it to all of my friends. It was informative, interactive, and entertaining. My boys wanted to do it everyday and were so exciting when it was their time slot and they could go online to learn more. We look at clouds differently now. They are no longer rain clouds, rather cumulonimbus clouds. My youngest stared drawing pillow lava in art class.

This is an exceptional program. My son used this for physical science and air/space 2 years ago. On standardized testing he has scored consistantly above the 80th percentile for the past two years. However, last year we used a book biology only with a dissection lab and on this year's testing he scored about the 50th percentile for that information. I deduce that PLATO presented the information in a more meaningful and memorable manner.
I must say that the PLATO experience was also more pleasant than the book only. I am looking forward to p...(more)

Just want to let you know that my two boys look forward to PLATO science three times a week. They would love to do it everyday! We have also had several occasions where they have told me some interesting facts and when I asked how they knew that they replied "From our computer science program." We definitely plan to renew our subscription and have already recommended to friends. Two of them have gotten subscriptions and also love it!

Plato Middle School science courses have been just right for our current homeschooling needs. Our son is able to watch the lectures and complete the questions with minimal reading, keeping him grade level in science and freeing me up to spend extra time tutoring him in language arts.
NB, Co-op Member
We have used a number of PLATO learning courses over the years.

The middle-school level courses are very thorough. The voice speaks quite slowly, which bothered my kids a bit (probably done to accomodate English language learners), but the content was high level.

Where they shine is in the high school level courses. The content is very high. My kids are now taking an AP Biology class, and much of what they are studying was already covered in the PLATO program. With the available study guides that the students can print and complete, t...(more)

I am using the Earth and Space Science with my 14 year old son. Content wise, it is very thorough. It is also done very well with the picures, diagrams, etc. He really enjoys learning Science in this manner. The website is also very easy to use. I like that you can see at a glance what you have mastered.
Debbie Wilks, Co-op Member
Thank you so much for negotiating affordable pricing on the PLATO Learning courses! The quality of instruction for the Algebra and Middle School Science courses is excellent. Please keep this great program available so we can explore other courses!
N.D., Co-op Member
We bought both the life science and physical science for my children. Both we wonderful programs that exceeded what we expected. I would say if you are looking at either of these programs they are worth it.
M. Fletcher, 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.
