In this activity, learners explore the unique challenges in transportation engineering, such as devising a method for skiers or hikers to get to the top of a mountain.

In this activity, learners construct a simple air pressure launcher for paper rockets.

In this activity about the heart (on page 22 of the PDF), learners examine sheep or chicken hearts to learn about the heart's structure and the flow of blood through the heart.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

In this activity, learners explore chemical engineering and how the processes of chemical plating and electroplating have impacted many industries.

In this "Sid the Science Kid" activity from Episode 106: My Mushy Banana, learners explore the effects of decay by comparing and contrasting something (an old pumpkin) that's decayed with the same thi

In this activity, learners try to figure out who has their matching rock type by reading a description of their rock (no talking!).

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this Bob the Builder(TM)-themed activity, learners explore what it means to work together as a team.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).

Learners will build and experiment with their own windmills made from simple household materials.

In this series of exercises, learners predict the conditions necessary for bacterial growth, test their predictions and at the same time practice the aseptic techniques and safety procedures needed wh

This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.

In this activity (page 7 of PDF), learners will identify the general two-dimensional geometric shape of the uppermost cross section of an impact crater.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.

In this activity, learners explore the properties of metals at four stations. The stations include A) Magnetism and Breakfast Cereal; B) Conductivity of Metals; C) Alloys; and D) Metal Plating.
