Young scholars examine how candles work and how scientific theories are developed and tested. Students propose hypotheses about what is burning in a candle then perform tests in order to develop their scientific theory. After a teacher...

Fifth graders, in groups, complete an experiment/activity in which they dissolve salt in a cup of hot water and then observe what happens as the water evaporates over the next few weeks.

Students investigate the changes that can take place in an aquatic environment. They conduct research using a variety of resources. The research is used to report different possibilities of change because of abiotic or biotic factors.

Learners explore the habitats of mammals and their physical characteristics. They research examples of mammals that must deal with daily changes in their habitat and how they cope with them. In small groups, students create a table...

High schoolers explore solubility of gases in water, Henry's Law, LeChatelier's Principal, and supersaturation of gases in water.

Students explain basic components of the space shuttle stack and the chemical fuel makeup and storage used on the external tank of space shuttle. They discuss findings of Columbia mission accident. and the safety improvements that have...

Students, in groups, take samples from a creek and keep a field journal on their samples. They also perform tests on their samples.

Sixth graders examine the processes and transformations that occur in carbon pools. They play a game to identify paths taken by carbon through the environment.

Learners play the role of scientists testing for water quality in the area. In this ecology lesson, students determine the water sample's pH, temperature, dissolved oxygen and turbidity. They write a journal reflection after the activity.

Students conduct a series of activity that demonstrates Charles' and Boyle's Law. In this chemistry lesson, students determine the relationship among pressure, volume and temperature. They solve problems using mathematical equation.

Students use the six step scientific method to experiment with the differences in adhesives. Students test for tack, shear, and peel in these activities.

Students study the different types of metals.  In this investigative instructional activity students watch a demonstration on the effects of temperature on atoms and take a tour through baone matter.

Students explain the value of blood in trials.  In this DNA lesson students work together to collect and share information and ideas that they come up with after learning how to distinguish blood from other stains. 

Sixth graders discover the difference between weight and mass. In an experiment, they examine the Law of Conservation of Mass in action and discuss if a physical change causes a change in mass. They observe chemical and physical changes...

Young scholars list some of the health effects of radiation exposure. They are engaged in a unit on nuclear power by demonstrating the potential environmental health risks involved.

In this science worksheet, students solve the crossword puzzle using the context of energy to acquire a new understanding of vocabulary words.

Students use authentic satellite data on the NASA website to determine when the sea surface temperature meets the criteria to induce coral bleaching.

Students understand how clouds are formed. In this cloud lesson, students participate in three experiments to make clouds. Students complete activity sheets for each experiment.

Students build metal atomic models using styrofoam. In this chemistry instructional activity, students identify the different unique properties of metals. They explain how metal atoms bond.

Students explore how clouds are produced through three different age-appropriate hands-on experiments.

High schoolers recognize that the sun is the source of energy driving atmosphere cells. They relate the motion of the atmospheric cells to mantle convection cells. Students recognize that the function of atmospheric cells is to move heat...

Pupils write the electron configuration of elements using the Aufbau principle. In this chemistry lesson, students build their own key that demonstrates the principle.

Students determine
