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.

Your heart pumps blood throughout your body in one direction, around in a loop. In this activity, learners will make a model of one type of heart chamber called a ventricle.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

Millions of organisms can live in and around a body of water.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

In this activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.

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

Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.

In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.

Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.

Many people get water from a source deep underground, called groundwater.

Most people will break a bone in their body at some point in their life, but how much force does it take to break one?

This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.

In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

Learners use Duplo bricks to build antibodies with shapes that match model viruses.

In this activity, learners look at and touch marine animal skulls to compare them and think about what they eat.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

This is a guide for facilitating interaction at a touch tank with marine animals. The instructions are for setting up a display in an informal science center, but could work anywhere.

Most people break at least two bones in their lifetime. In this activity, learners will use celery stalks to model the many ways that bones can fracture.
