In this activity, learners create a garden in a disposable glove. They learn about the conditions necessary to make the seeds sprout and actively participate in caring for their plants.

Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

This activity (on page 2 of the PDF under SciGirls Activity: Forecasting) is a full inquiry investigation into meteorology and forecasting.

In this math lesson, learners record and graph plant growth and interpret data. Learners plant seeds, and once the seeds sprout, record the change in height of the plants for several days.

In this activity, learners use an astrolabe to measure the altitude of objects. Learners will first practice taking measurements by measuring the altitude of trees and buildings.

Learners construct a bird feeder from re-used materials. After hanging their feeder, they keep a journal about what birds visit the feeder.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

This activity (page 2 of the PDF under SciGirls Activity: Bogs) is a full inquiry investigation into decomposition.

In this indepth hands-on activity, learners build a structure that allows them to observe the growth of roots and the correlation between root growth and stem extension.

The Butterflies in Space Teacher's Guide uses "life in space" to encourage learners to conduct their own open-ended scientific investigations.

In this activity about physical stress (page 28 of PDF), learners discover that muscles and bones need to work to stay strong.

Use the Zoo Calendar (page 1 of PDF) to involve learners in interdisciplinary, whole language, and writing activities about ecological concepts.

In this activity, learners will train to develop upper and lower body strength in their muscles and bones by performing body-weight squats and push-ups.

In this activity, learners train to increase muscular strength and improve upper and lower body coordination by performing the “bear crawl” and the "crab walk.” Learners perform the exercises over tim

In this activity, learners will train to improve lung, heart, and other muscle endurance as they walk a progressive, measured distance.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity, learners will train to increase bone strength and to improve heart and other muscle endurance by performing jump training with a rope, both while stationary and moving.
