In this activity, learners take core samples of candy bars with a straw and carefully observe & excavate their sample, modeled after what the NASA Perseverance rover will do on Mars.

In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex

In this activity, learners create their own weather forecast map.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this activity, learners create a star show and discover how they can prevent light pollution. Using simple materials, learners first design constellation boxes.

In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

In this activity, learners try to blow up a balloon hanging inside of an empty bottle.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

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.

This fun and simple hands-on astronomy activity describes techniques scientists use to find planets orbiting other stars.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.

In this activity, learners use their hands as tools for indirect measurement.

In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.

In this activity, learners create their own icons for a forecast-at-a-glance poster for their classroom/learning space.

In this activity, young learners go on a walk with caregivers and use their senses to observe nature with the help of scavenger hunt sheet.
