I am new to homeschooling this year and I don’t know what we’ll be doing for a STEM program. My children love hands-on activities, so I know I need to figure something exciting out soon! I love your blogs and posts with ideas that I can use at home!
I love STEM! Our favorite project so far has been creating rockets and roller coasters. With rockets each child was given one piece of paper and a roll of tape. The object of course was to make it fly. After some trial and error they did. There were a lot of great aha moments. With roller coasters they were gone foam pipe insulation cut in half, marbles and tape. Third goal was to create a coaster that had one loop and one jump where the marble landed in a bucket at the end. Lot of fun!
Diana M says
We love STEM projects here. Gak is always a favorite with the youngest. But my older two really enjoy physical engineering challenges, like boat or bridge building with limited materials. I love watching them be create.
Kyla Hughes says
We love marshmallow and toothpick STEM building challenges!
Traci K says
My son loves to take apart anything that doesn’t work. We try to figure out what the different parts do ( which is quite hard with some of the electronic items) but we have learned a lot. And even fixed a few things!
We use a variety of blocks and craft materials regularly and come up with challenges as a family. We also have a science book of experiments that we like to pick from too.
Kendra Wright says
Where do you enter?
Karyn Tripp says
SORRY!!!! My form wasn’t showing up. It is there now.
Stacey Ross says
One of my favorite STEM activities is creating square foot gardens with my children. Using a seed package can yield a wide variety of mathematic concepts. The square foot garden concept allows for measuring, adding, multiplication, and division– and al of this on top of the scientific nature gardening gifts children. Children use technology to plan the design, capture changes, and share their learning.
Stem is such a great addition to homeschool. We like to incorporate art as well (steam). This year we will have weekly stem challenges. The kids will choose from a bin of pre prepped bags and complete the challenge inside.
Alyssa Ziegler says
I was teaching 5/6 science and math. I connected the two subjects and incorporated other subjects to create STEM projects. This past year we created gravity cruisers and presented our projects to the entire community. This year I was moved to 4th grade the week before school started! STEM is still something I want to incorporate so I am looking for new ideas for a different grade level.
Mary W says
Using an extra large suntan lotion bottle ( which I received from a friendly drug store display) we compared the size of items for a person who used a regular sized suntan bottle Most of which are are about one human hand tall. This introduced our nut on ratio and proportion. It also used estimation and opened their eyes to actual applications.
As we are entering this wonderful world of STEM in our homeschooling, I am so excited to have this opportunity to enter such an awesome give-away! Thank you thank you!
Such great ideas. My guys love chemistry. Making bouncy balls and goop are a favorite. I need to try some of these other experiments.
Kelly Kiggins-Lund says
My favorite STEM based activities are biology and chemistry based. We’ve even done crime scene investigation science studies as my father is a retired police officer.
Danielle Evans says
I give a building challenge every day and that is our favorite stem activity!
I love having my students in eighth grade learn about velocity by building their own marshmallow guns using a variety of materials and then testing the effectiveness.
I need help with stem, we don’t do it enough!
Andrea Peak says
Making a volcano is one of our favorites
We love to do anything related to physics. My kids had fun hitting a plate out from under an egg and watching the egg drop straight down into a cup of water.
We’ve really enjoyed garden projects this season. Music lessons are in their honeymoon stage & I’d be excited for ways to continue their enthusiasm. We’re looking into Rube Goldberg now! I’d love to play more games with our 7 & 10 year old kids.
