“The kids loved it. I have 52 students/day 3rd - 6th graders and only 45 minute blocks with each, so this was perfect science activity for the range of ability and short time to execute. THank you! I thought I wouldn't be able to do any science Fridays this year, but I think I will be able to do some of them! The kids LOVED it - and the spiders double as reasonable kites! :)”

· Jennifer · Teacher
“The children had a lot of fun making it and they experimented different ways of making the spider crawl - upside down, sideways, at an incline, going over objects, etc. I let them come up with their own ideas. My kids are English Language Learners and there was a lot of language involved so a win all around. Thanks and keep these wonderful activities coming!”

“The embedded visuals and videos were very engaging for students. Also the scaffolding in the drawing instructions made the task much more manageable for even artistically challenged students. The mystery lesson was able to be completed efficiently and matched the estimated time markers in the lesson prep.”
· Kimberly · Teacher
“The kids loved the dancing spider! Everyone was out of their seats copying the peacock spider dance. The students also enjoyed mimicking the behavior of the crab spider snatching its prey.I loved that they practiced doing a detailed drawing to learn about the parts of the spider's body and how each spider is a little different based on its adaptations. Thank you for another wonderful lesson!”
· Lisa · Teacher
“I am legit loving these lessons! They are super fun and engaging, informative and easy peasy for me to set up. I seriously don't know how I've taught science up to this point without Mystery Science. And I am not being the teeniest bit hyperbolic in my praise. If anything I am playing it cool (okay, maybe that is a little hyperbolic) but I really do love it! A lot. (What's the law on marrying online subscriptions?)”
· Mary · Homeschooler
“The students loved using your pics to create accurate drawings of the spider they picked, they loved picking up a few quick facts, and of course they thought it was cool that the spider could actually climb!! As a 4th grade teacher, I was able to reinforce earlier learning about structure and function. Another thing I love is how the kids really learn to listen and follow directions on these activities!!”
· Cynthia · Teacher
“Watching the videos about spiders wowed the kids and got them excited to learn more about spiders!”

· Lillian · Teacher
“There are spiders crawling all over my room! They had so much fun. There is a lot going on at our school today and we did it in increments. I love how much spider discussion we have had today. ”
· Susan · Teacher
“My third grade class loved the video mini lesson on spiders and the extension activity. Our spiders were really moving. My studentslook forward to Mystery Doug every week. You are like a member of our class. The students learn a lot and have fun at the same time. Thank you for preparing the videos, and we always love when they have extension activities.

Prep Instructions

We suggest students work in pairs. Homeschool students will need a partner to help. Students will need a little bit of space in the classroom to spread out for testing their Spider Climbers.

Prepare Yarn

Cut your yarn so that each student will have a piece that is about 6 feet (2 meters) long.

Separate Supplies for Distribution

You may want to separate your supplies for easier classroom distribution. In addition to their Spider Climber template, each student will need the following supplies:

Spider Climber supplies

Teacher Tips

If a Spider Climber doesn’t run up its string, make sure that the string is not taped to the inside of the template, and also make sure students are holding the ruler and not the string when they are in the “Fly” role. The climber will only work if the string is able to move freely.

Spider Climbers (Grades K-2)

For the younger grades, we have provided three Spider Climber templates, each picturing a different spider (Jumping Spider, Crab Spider, and Orb Spider). In a class, we suggest giving students a choice of which spider they’d like to color. If students finish early, you can have them color in the other spider templates.
