In this design challenge, learners will practice empathy and design thinking skills by creating an invention of the future.

In this activity (page 1 of PDF under SciGirls Activity: Pet Handedness), learners will construct a simple spinning top out of a circle of construction paper, a film canister lid, and a bamboo skewer.

In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp

In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.

Learners explore the endless possibilities of cardboard engineering in this open-ended STEAM activity. Practice being creative by building structures with no glue, only cardboard and scissors.

In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.

In this activity, learners will explore engineering concepts to construct a blanket fort using materials sourced from home.

In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

In this activity, learners will engineer a roof using simple materials to protect a construction paper person from a rainstorm.

In this activity, learners design and build their own parachute using household materials with the goal of landing their passenger safely on a target.

In this activity, learners explore different ways to stack cups to meet a personal goal.

In this activity learners will build structures out of blocks and then roll balls to try to knock them down.

In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

Learners follow the template to build and fly a paper helicopter.

In this engineering activity, challenge learners to make a "grabber" that can pick up trash. Learners use simple materials to create pinchers that can grab small items.

In this activity, learners investigate balance and symmetry by designing a symmetrical butterfly, using a paper cutout.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.

In this math activity, learners use what they know about shapes to copy a friend's hidden picture. Learners create a design out of pattern blocks and then hide their picture behind a screen.

In this engineering activity, challenge learners to invent a water filter that cleans dirty water.
