In this activity, learners will rate the day, a book, or something else on a scale from -2 to 2. This activity works well for groups of all ages.

In this nighttime, outdoor activity, learners keep a record of what they see in the sky by drawing constellations, the Moon, and making note of the weather and conditions each day.

In this activity, learners model a population of deer and see how the number of deer changes over time.

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this activity related to climate change and data analysis, learners examine temperature and precipitation data to determine if climate variations are due to El Niño.

This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.

In this on site "field trip" activity (located on pages 6-9 of PDF), learners get hands-on experience identifying building materials by playing "Building Bingo".

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

In this family or group activity, learners create a nature journal by visiting a local nature center or backyard, observing creatures in their natural habitats, and sketching what they see.
