Plants need nutrients to grow. This is why we apply fertilizers to grass and food crops. In this activity, learners will explore how fertilizers can affect lakes and other bodies of water.

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.

In this experiment with planaria (a type of flatworm), learners will investigate the capability of different body sections to regenerate.

In this activity, learners simulate taking HIV antiretroviral drugs by using Tic Tac mints and Kool-Aid packets.

In this health activity (located on page 4 of the PDF), learners will discover the importance of hand washing by observing mold growing on potatoes.

In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.

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 environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this hands-on botany activity, learners sprout vegetables in film canisters.

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

This lesson plan enables learners to explore the differences between weather and climate.

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

This activity shows you how to make a mold terrarium using a jar and leftover food.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

In this activity, learners use food scraps from the kitchen to grow new vegetables.

In this activity, learners model estuaries, artificially enriching both fresh and salt water samples with different amounts of nutrients and observing the growth of algae over several weeks.

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 astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).
