Topographic Maps…

A cold wind is blowing fiercely. Her blonde, plastic hair “flips” in the wind while she treks up the 5 whole inches of this steep, mountainous terrain. If only she had looked at her handy-dandy topographical map to find the easiest way up, she wouldn’t have almost fallen off to her demise

That’s right everybody we are learning about TOPOGRAPHIC MAPS!!!!

To go with our last lesson about maps, it was time to learn a little bit about elevation! These maps offer more specific information about height and steepness of geographical forms. Of course there is other information included on these maps, like depth of water bodies, populations, camp sites, waterways and other natural formations. The lines that are on the map represent elevations. To understand this better, we went for the Play-Dough to see it in a more 3D way.

This was our process: first we grabbed a nice big hunk of dough and shaped it into a mountainous terrain. Then, we poked holes evenly up the side. We grabbed some fair, innocent citizens of the United Vintage Polly Pocket Nation and sprinkled them across the range (making sure they had their phones in case they got lost!) to remind us of the potential hazards humans can face when traveling without a Topo (that’s lingo for topographic) map! We then traced a line around the base of the mountain and with a piece of thread, cut on the first dotted line (closest to the bottom) and lifted of the top of the doughy fortress. Then we removed to bottom and set it aside but didn’t squish it… If you’re doing this yourself repeat the last couple steps until you’ve cut on every dot. TRACE! CUT! LIFT! SET ASIDE! TRACE! CUT! LIFT! SET ASIDE! WHOOP WHOOP!!!!! Once you’re done tracing, cutting, lifting and set aside-ing, you can see that on the lines on the paper have left a 2D representation of the doughy mound. After doing this project, it was much easier to understand which would be the easiest and also, the most dangerous path of travel for our Polly Pocket hikers. Lines closer together – STEEP! Lines further apart? Better.    Much better.

The wind continued to blow. Blonde, plastic hair still whipping in the wind, she reached the summit. Only to find her tea had gotten cold and her Biscoff biscuits had frozen. No matter. With her topo map in hand, she found the quickest and safest route down to the vintage civilization and headed straight to the cafe for a slice of rustic pumpkin pie.

Tippity Toppity Top!

As a fun school project involving rotation, inertia, torque and velocity, we made a couple tops! Made out of wood, these laser cut spinners are smooth to the touch and they are easy to put together. Adding color to the patterns was fun and it was cool to see how they changed once in motion. The faster they rotated, the more the colors blended. The tops are made by a company in Texas named Bright Beam Goods. Check them out, they also have cool puzzles!
