Tenth graders are provided with a piece of paper such as index, art, construction, or computer coating it with a universal indicator. They use cotton swabs HCl and NaOH to draw a picture repeating the same process using lemon juice and...

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.

Students explore the skills and information needed to complete a science fair project. They follow guidelines to create an document their science fair project.

Students apply an interactive smog visualization application, Smog City to see how ozone levels are related to population levels and emissions. They study associated vocabulary and complete a worksheet.

Students utilize The Nature Park Adventure educational software program to Introduce Modelling, Including the Estimation of Angles.

Sixth graders create a Venn diagram of different soil types. They plant cord seeds in clay, sand, and fertile black soils are record their growing rates. After two weeks they discuss the effects of soil types on the growth process.

Fifth graders test the shelters that were built in a prior activity. They determine the level of durability and water resistance of these shelters through a scientific investigation.

Ninth graders explore the concepts of motion, velocity and acceleration through graphing their own movement using LoggerPro. They become more familiar with the computer technology. Students explore graphing in real time and graph on...

Students determine the changes in different types of water in a sealed container over time. They investigate how to measure dissolved oxygen, temperature, and carbon dioxide with calculator or computer probe-ware. Students determine the...

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.

Fourth graders explore the earth's revolution around the sun and the changes in weather that follow this motion.

students study bird migratory patterns and the methods that researchers use to study them. Students are introduced to the concepts of the study of bird movements.The skill of scientific questioning is used to find results.

Find out what variables are in a scientific investigation and what the difference is between an independent, dependent, and controlled variable. Look at samples of different types of variables and find out what makes a good variable.
