Students hypothesize whether the soil sample may have lead contamination and why. They describe what they see happening with the soil samples and the corresponding swabs. Pupils write a brief description of what they observe as the...

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...

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.

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.

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

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...

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

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.

Students work together to discover the flow rates of faucets and rivers. They relate their results to engineering and applied science concepts. They make predictions on the flow rate of a nearby river in their local community.

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 use Robolab sensors and software to design an experiment that incorporates the use of temperature probes. They conduct the experiment, complete a lab sheet, evaluate the results and then consider if their hypothesis requires...

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...

Tenth graders examine the effects of the breakout of the West Nile Virus. They make predictions on its origin. They develop and present an action plan to stop the virus from spreading.

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 explore robotics. They design and draw a robot to fit a specified function. Students examine motor functions necessary for the robot to perform. They discuss types of sensors available to assist in the building of a robot.

Students determine their lung capacity by completing a science experiment with a bottle of water. In this lung science lesson, students discuss the lungs' purpose. Students complete an experiment to determine their lung capacity using a...

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 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.

Students engage in a lesson that is concerned with the allocation and finding of water resources. The location of different settlement areas is considered as one looks how the water is distributed. They map some of the early Spanish and...

Students extract DNA from split peas. In this biology lesson, students hypothesize what DNA looks like and perform the experiment to verify their hypothesis. They explain the importance of DNA in living things.

Students evaluate their current food choices. In this health science lesson, students test different drinks to rate the amount of Vitamin C content. They discuss results in class.
