In this online activity, learners find out whether they are smart enough to survive as a plant.

In this activity, learners will dissect a pumpkin or winter squash to learn the parts of the plant. This activity gets your learner hands on with every part of the plant and will be messy.

Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).

This guide outlines how to plant a garden even if you don't have a yard!

In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.

In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

In this activity, young learners will make their own flower seed nursery in an egg carton.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this activity, learners will design a seed and test how it travels. Learners will use the Engineering Design Process to create a seed which can move from place to place.

In this activity, learners are challenged to design and build a miniature tree house in a potted plant. This activity uses engineering concepts to encourage creativity.

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

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

As a long-term project, you can rear monarch butterflies at home or in a classroom.

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 experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.

In this outdoor activity, learners cut through and investigate rotten logs and then make log-profile puzzles for each other.

In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.
