In this activity (on pages 20-23 of PDF), learners build a model of a power plant using simple materials.

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.

In this activity, young learners (2 years and up) explore flower and plant biology and pollination by planting seed in a homemade seed starter.

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

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

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

In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this two-part activity, learners compare and contrast a variety of life cycles to better understand different organisms and how they develop.

In this environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.

In this outdoor activity, learners become beachcombers as they walk on a sandy beach in search of evidence of life.
