This is an activity about a very important ingredient in most baked goods - gluten! Why is gluten so important? Without it, there would be nothing to hold the gas that makes bread rise.

This modeling activity allows learners to discover for themselves what Mendel uncovered in his famous pea experiments.

In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.

This lab activity has learners create a pendulum with a one-second period.

This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

Learners build simple catapults and use them to launch cotton balls.

In this activity, learners discover how solar energy can be used to heat water.

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.

In this lab (Activity #1 on page), learners explore how we see color.

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.

In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

Learners use compasses to detect the magnetic field created by current moving through a wire. This is one of four activities learners can complete related to PhysicsQuest 2008.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery

In this activity, learners investigate procedural memory.
