  • Hi! I’m listening to my 6.5 year old ASD/ADHD/SPD/GAD kid in his science class with Blair right now, and I just feel like everyone should know how incredible these classes are. They’re hands-on, engaging, absolutely challenging but also totally appropriate for interested young kids, and FULL of great science. Blair and Alison have been so patient and kind with Gus and they do a great job developing a comfortable and exciting learning community. We’ll definitely be signing up for more classes and I’ll recommend them to anyone who’s looking. If you’ve been on the fence, give it a try! Update: He is running around the house finding simple machines, and just grabbed a pencil to draw as many types of levers as he can imagine. 💜 Becca and Gus


  • We are absolutely loving the format, content and of course teaching in our Thursday Science Series! Thank you for all the hard work you have done. It’s fabulous and hands down the best homeschool class my kids have ever taken. C.D.


  • My child is really enjoying your class and I love how you are teaching to this age group! I wish there were more classes like this for the elementary age group you are offering! S.N.


  • I wanted to let you know that when I ask the girls what their favorite class is, both agree, it is your online science series :-). C.W.


  • My child has genuinely enjoyed your class. My father is a life-long ecologist and so my child has been exposed to a lot of science. It’s tough for me to find something interesting and engaging enough for them - and you’ve delivered in spades! Thank you! Your excitement and engagement with these kids is terrific! B. is genuinely enjoying the classes!!! We can’t wait for more!!! K.P.


  • R. loves all science and the way you teach is so engaging for my child. The hands on projects have been a lot of fun. Thank you for sharing your enthusiasm with the children. It is wonderful!


  • How The Earth Got It’s Shape was wonderful. Thank you. M. cracks me up. I am purposely not around so she can tell me ALL about it after, as that is really how she learns best, by teaching. The way she talks about you, is so endearing. She says, Mom, Blair is seriously in love with science. LOL. :)


Blair Lee will have your children LOVING science as much as she does!

Class Information and Details

Age Range: 7 - 11

For each session we have 3 weeks of class followed by a 1 week break. There is 12 weeks of live instruction for all 4 sessions spanning 15 weeks.


Engineering Basics with Beavers 

When European colonists arrived in North America, there were an estimated 400 million beavers. These beavers had engineered 250 million beaver ponds, turning free-flowing creeks into fertile wetlands that supported a wide range of plants and animals. After being hunted to near extinction, beavers have made a comeback. As many as 15 million beavers now swim in North America’s waterways. Scientists have come to understand the importance of beaver engineering to healthy inland waterways.

Flight 

In this project-based science series, students will engage in hands-on learning as they use their design thinking skills. How do birds, bees, kites, and airplanes all fly? Once learners understand the four forces of flight, they can apply what they are learning to answer that question!

Historical Inventions

History and science come together in this project-based science series. Students will engage in hands-on learning as they make models of 3 important scientific and historical inventions. Learners will investigate the design thinking skills used by some of history’s greatest thinkers. In addition to learning the history, science, and building techniques of these inventions, each week we will brainstorm additional building innovations students can make to their models.

Dinosaurs 

Dinosaurs were (and are in the form of birds) an incredibly diverse group of animals. For much of their existence from 243 million years ago to 65 million years ago, when all non-avian dinosaurs went extinct, they were the dominant terrestrial vertebrate (land-living animals with a spine).

But these non-avian dinosaurs did go extinct. So, how do paleontologists take a few bones and determine what a dinosaur looked like? In this 3-week series, learners will build models of dinosaur skeletons. We will look at three important geologic periods to look at important evolutionary steps that occurred in this diverse group of animals.

This series uses the book Excavate! Dinosaurs for the model templates.

This is the first time this class has been taught, so there are no reviews for it yet. Below you will find reviews from parents and students who have taken other classes with Blair.

  • Annabelle looked forward to taking Blair’s Marine Science classes every week. She was so excited to contribute to the discussions and really felt empowered by how Blair and Alison interact with the learners. Annabelle now feels more confident sharing her marine science knowledge with family, friends and really anyone that will listen. It also reignited a passion to save marine life. Annabelle felt so proud of the reports she completed and presented to the class. That was also thanks to the enthusiasm, love and support given to her by her AMAZING teachers. Thank you Blair and Alison!!! Annabelle is always engaged and learning. I love how real terminology is used and learned. No dumbing down. High expectations that all seem to meet! Blair and Alison are so kind and really engage with each learner and make sure everyone is seen, heard and valued.  Yvonne And Annabelle 
  • Blair really brings the subject to life when she teaches. My daughter can't help but be so excited about the topic she is hearing about from Blair! Marine Biology has such amazing nuances on the amazing creatures of the ocean. I found myself wanting to listen in on my daughters class, as I LOVED hearing so many cool things about kelp, and endangered species. My daughter leads the way when it is time for this class. (and not all her classes) She gets to class early to chit chat and see her instructors and LOVES learning in such a safe, and fun environment. Colleen and Millie
  • The dog communication lab was really fun. It was the best online class I’ve ever had. My daughter had an excellent experience with Blair in the Wolves class. She was always very excited to login to each class, and came running out with a smile and tons of facts to share after each session. Would absolutely recommend it. We look forward to her next classes! Kate and Alice
  • From the student: The instructors made the material, which might sound bland and boring, super fun. Blair is an exciting teacher who is clearly very enthusiastic about her work. From the parent: Blair is very supportive of her students and was prompt with communication if we ever needed anything outside of class hours. I would recommend her classes to anyone! Rachel and Carlos
  • Loved the Interactive part. My learner is very social (can get distracted/be distracting) but the teacher was good at letting her meet her social needs and gently redirecting when needed. My daughter is very engaged in the content and enjoys the live and interactive format of the classes. Blair Lee does a great job with these classes. Erika and Hazel
  • Biology 2 has been a well structured class. The course content and materials cover the subject well and the weekly meetings have been welcomed for continuity. Blair's enthusiasm for the subject comes across strongly and is encouraging for the young learners. Sheila and Elisa

Reviews for SEA Online Classes.

  • SEA online classes have a way about them that ENCOURAGES my child in a way that I know that EVERY instructor will bring my child to life, and empower my child to work harder as she WANTS to do her best. I never worry about a teacher who shames or uses cohesion in class. That is a gift! SEA has teachers of very high character and professionalism. C.D.
  • From homeschooling parent classes to learn how to best guide our learners to outsourcing subject classes with passionate teachers, SEA Online Classes have been a vital part of our homeschooling journey. I am so grateful for the variety of subjects offered and for the wonderful team making it all happen. We are happy to support SEA online classes, where we hope to be learning for years to come! Outsourcing some of our subjects has been a positive change to our homeschooling curriculum. It has allowed myself and children to stay on target this year and I'm very appreciative of the teachers and this forum for our learning. Sheila
