In this activity, learners will create their own lava lamps. Learners will explore density, effervescence and chemistry through this activity.

In this activity, learners will explore acid-base reactions and create their own bubbly results.

In this activity about light and refraction, learners discover how a lens creates an image that hangs in midair.

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.

In this activity, learners design a bungee jump for an egg using nylon stockings.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.

In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

In this activity, learners are challenged to design, build and test a birdhouse that will stay cool in the sun.

In this quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.

Learners attach an egg to a rubber-band bungee cord and drop the egg.

In this design challenge activity, learners build a tower that’s at least 12 inches high with two or more parts that move (spin, sway, or flap) in the wind.

In this design challenge activity, learners build a device to carry a Ping-Pong ball from the top of a zip line to the bottom in four seconds (or less!).

In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.

In this amazing activity about light and reflection, learners will use a pie plate and reflective strips from a mylar balloon to try to morph their face into a friend's.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

In this activity, learners build a seesaw powered by magnets.

This lesson guide includes six simple and quick activities to help learners better understand Bernoulli's Principle.

Learners design their own experiment to investigate how pollution diffuses through ground material.
