In this activity, learners will investigate the impacts of harmful phytoplankton using NOAA's Coastal Services Center Harmful Algal Bloom Forecasting (HABF) Project data.

In this quick activity, learners observe how wind creates ocean currents.

In this activity, learners design a crushing test and discover that identifying and controlling the variables may be difficult.

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 activity, PVC pipe, plastic water bottles and vinyl tubing are used to make a simple working toilet model. The model shows the role of a siphon in the flushing of a toilet.

In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.

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

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

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.

The objective of this inquiry-based lesson is for learners to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms.

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

In this activity, learners discuss how life is defined and conduct a simple experiment, looking for signs of life in three different “soil” samples.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

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

In this activity, learners predict whether a ball on Earth or a ball on the Moon bounces higher when dropped and why.

In this online activity about heart disease, learners will pick one of three patients (based on actual patient histories) and help a cardiologist diagnose and prescribe treatments for him or her.
