Historically, sea floor mapping (bathymetry) was done by soundings.

Using simple, inexpensive items, learners build and test submarine models.

In this activity, learners explore liquid crystal thermometers to observe how heat flows by conduction, convection, radiation, and evaporation.

This activity (located on page 4 of the PDF under GPS: Sea Turtles Activity) is a full inquiry investigation into testing a repair material.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

In this activity (11th activity on the page), learners use pennies to test their hearing acuity.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this activity, learners determine the elastic and plastic properties of different types of metal wires.

In this activity, learners build a recording timer made from simple materials (e.g., small dc motor, sharpie pen, craft sticks, adding machine paper tape, etc.).

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

This activity (on page 2 of the PDF under SciGirls Activity: Forecasting) is a full inquiry investigation into meteorology and forecasting.
