In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

In this activity, "write" a secret message in genetic code as beads on a string.

In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this four-day lesson, learners identify three-dimensional forms in castle design, research different parts of the castle with a focus on their uses, and design and enlarge a banner for the great ha

Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the atom's outer unstable

Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.

In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.

In this activity related to plant biotechnology, learners use the tissue culture process to rapidly produce clones (genetic copies) of a particular plant (cauliflower, rose cuttings, African violet le

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

In this activity (on page 2 of PDF), learners make their own totem poles out of recycled materials.

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.
