When presented with three unopened bottles of water, students are asked to tell decide which one is contaminated with a microbe. Students work in small groups and role play being a Microbiologist, a patient, or a recorder. The patient is...

First graders observe two similar plants as one gets water and the other does not. They make predictions and chart the growth of each. They draw pictures of the plants after one week.

Students investigate aerodynamics by comparing and contrasting the flight of two gliders. They make prediction and observation charts and test a variety of hypotheses using paper gliders.

Working individually or in groups, 4th graders are presented with unusual or at least unfamiliar objects and are asked to speculate on what they are and/or how they are used. The intention is to get students to make careful observations...

Students examine how to act as archaeologists by examining artifacts. The inquiry is meant to teach learners about analysis of ancient civilizations and scientific finds. Fossil evidence is also covered to make connection to the...

Students complete experiments with three different bubble solutions to determine which one creates the largest bubbles. Before conducting the experiments, they discuss the ingredients in each solution, and make predictions on which will...

Middle schoolers hypothesize what forces affect the motion of a falling body. In this physical science lesson, students create diagrams and illustrations to support their hypothesis. They perform the experiment and record observations.

Third graders complete a diagram of the revolution of the earth around the sun and write a one paragraph explanation of the factors that cause seasons.

Students estimate how many drops of water can fit onto the surface of a penny and then test their hypothesis to find out. They also experiment with bubbles.

Students, after identifying and examining the relationship of temperature and air masses in association with smog and pollution, create a temperature inversion in a long aquarium jar. They experience what happens when smog builds up and...

Students study the historical figures and symbols of U.S. patriotism depicted on the penny, nickel, dime, and quarter coins. They explore the processes involved in making coins, and how metals canchange in consistency from the...

Students design and implement an experiment intended to measure and analyze the air quality of a particular location. They focus on looking for ozone and particulate pollutants.

Students are given a pond snail in a clear glass and asked to make observations on the snail's form and behavior. One of the key ideas is that seemly common subjects (like snails) often have surprising or interesting properties.

Students build their own wind turbine. In this physics lesson, students calculate the power output of their wind turbines. They evaluate their design and make the necessary modifications.

Students are introduced to the realm of social insects, their role in the environment and the biological features that make them unique.

Students decide how many times to spray a strawberry crop. They apply marginal analysis and discover the "law of diminishing returns."

Students work together to measure tree heights. They make predictions on what they believe the calculations are and answer questions during the experiment. They share their results with the class.

Fourth graders work together in groups to design and complete one science experiment of their choice. Following the experimental steps, they show their experiment and the results to the class in the form of a PowerPoint. They explain...

Pupils practice their skills of forming hypotheses by conducting various experiments.

Seventh graders create a time line of significant dates in the history of their nation. This requires students to examine the entire history of a country and make informed judgments based on their historical knowledge.

Students study the concept of sedimentation, the process of silting as it effects a man-make lake such as the Kansas-Lower Republican Basin.

Students investigate molecular movement while studying how to perform a chemistry investigation.

Students describe the effects of over-harvest on a salmon population. They explain the importance of salmon to many communities in Alaska. They manage harvest levels to maintain a sustainable population.

Students analyze data from a student discussion website and write a report on the outcome of an investigation regarding their local water quality. As part of a larger unit students then post the summary of their investigation on the...
