Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.

In this group activity, learners see and hear the speed of sound. A learner designated the "gonger" hits a gong, once every second, as the rest of the group watches and listens from a distance.

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 make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!

In this activity, learners construct a three-dimensional ambiguous cube to explore visual illusions and how our brains interpret or misinterpret information.

In this lab (Activity #2 on page), learners compare bacteria growth on two petri dishes containing nutrient agar. Learners touch the doors, faucets, etc.

In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

In this activity, learners calculate the width (horizontal diameter) of the blind spot on their retina. Learners make a blind spot tester using a piece of notebook paper.

In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

In this activity about scale, learners investigate the world of the very small by cutting a 28 centimeter strip of paper in half as many times as they can.

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

In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

In this activity related to the famous "Stroop Effect," learners explore how words influence what we see and how the brain handles "mixed messages." Learners read colored words and are asked to say th

Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en línea, en libros de consulta, y en calendarios y almanaques.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.
