In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.

In this math lesson, learners compare products to determine the best product.

In this weather activity (page 1 of the PDF), learners will construct their very own anemometer to measure wind speed.

In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In this fun snack and craft activity, young learners make "Ants on a Log" and their own model of an insect. The purpose is to learn the three main insect body parts—head, thorax and abdomen.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.

Why does milk make some people sick? In this activity learners explore this question and explore the chemistry of milk, and our bodies!

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

Learners play the role of materials engineers as they test the flexibility of different materials.

In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.

In this activity, learners create their own archaeological profiles.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

In this activity, learners design a device to solve a problem: how to get a ball out of a drain pipe.

In this activity, learners identify the DNA base bars guanine, cytosine, thymine and adenine. Learners create a DNA model using colored paper clips to resemble these base pairs.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.
