In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

In this activity (on pages 36-39), learners make a model of a watershed out of paper, then run water down the mountain to simulate how rainfall and pollution affect watersheds.

This marine biology activity (on pages 11-17) introduces learners to kelp (seaweed) forests that grow in the ocean and are home to many species of sea animals.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this activity, learners will build a design and build a place for pollinators to drink from.

This activity (on pages 23-27) lets learners simulate the work of scientists who take core samples of Earth's rocky layers to determine geological history.

In this activity, learners will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

Have you noticed the plastic rings that are used to hold six-packs of soda? Those rings are great for carrying cans, but they're real trouble when they become trash that animals can get tangled in.

Learners design their own experiment to investigate how pollution diffuses through ground material.

¡En esta tira cómica, Mateo y Cientina son detectives! Ellos usan sus destrezas investigativas para identificar de dónde provinieron algunas muestras de arena.

In this activity, learners will create a magnifying glass called a waterscope, using water and household items, to examine various objects.

In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

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 activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.

In this activity (on pages 10-17), learners discover how scientists study biodiversity and the health of the environment based on inspection of small areas—a process known as sampling.

In this activity (on pages 29-35), learners examine water pollution and filtration.

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.
