An engaging activity enlightens young chemists in this instructional activity on atomic structure. They play musical chairs through a series of concentric circles that represent electon orbitals. A laundry basket in the middle holds the...

Include a lab about alloys and magnets in your fourth grade science lesson. Young scientists read the necessary background knowledge about alloys, then choose which objects (a screw, a bell, scissors, or coins) will be attracted to...

Students examine the concept of potential energy and see that it is the ability to do work.  In this energy lesson students complete several activities on potential energy. 

Students attempt to design and build the most stable "earthquke resistant" structure. They create model buildings and test them on a shake table to see which design holds up the best.

Students complete a hands on activity to determine how scientists use indirect observations to define problems that are not directly measurable. They complete an associate student handout.

Young scholars make observations of a bouncing ball and study how it travels.  In this height lesson plan students complete a lab activity and describe and explain the motion of the ball. 

Kindergartners learn about the ways force can stop and reverse motion. Several illustrations of children help them determine if the motion is causing an item to change direction. Next, they conduct an experiment to see if a water balloon...

Students discover and identify positive and negative electrical charges and understand that like repels and opposite charges attract.  In this physics instructional activity, students observe how friction can be used to give...

How do the laws of motion work in space? Learners explore Newton's laws of motion in different experiments as part of the Christa's Lost Lessons series. They rotate around the room in three stations to experience each law in action using...

Shake up your lessons on earthquakes. A simple seismograph lets scholars record "earthquakes" in the classroom. These earthquakes occur when classmates drop balls from different heights. Young scientists measure these with seismographs...

Students observe how different density soils and rocks behave in wind and in water. They make predictions and careful observations as they explore sediment transport and sediment rates in streams and rivers.

Students explore the reaction rates of an enzyme-mediated reaction through experimentation. In small groups, they use everyday objects to demonstrate the effects of environmental variables on enzyme function. Students graph and...

Students explore reaction rates of an enzyme-mediated reaction. They examine the effects of environmental variables on enzyme function. Students collect, graph, and analyze data relating to the reaction.

Young scholars discuss the topic of streamflow and how it occurs. They take measurements and analyze them. They interpret data and create their own charts and graphs.
