Students study different formats of data and determine the nitrogen dioxide concentrations.  In this seasons lesson plan students understand the different relationships that NO2 can have.

Explore the properties of gases through one activity and two investigations in which super scientists observe the changes gas makes when encountering different conditions.

Model hardness testing with a self-designed hardness test. Young scholars rate the hardness of different types of aspirin using the Vicker's Hardness scale. They then relate hardness to the solubility of each aspirin tablet.

Young scientists get the chance to dissect pellets "owl" by themselves to determine the owls environment and nourishment. This is the third part of a three-part series. 

What variables change heart rate? Young scientists observe the beating heart in Daphnia to understand these variables. They make changes in temperature, chemicals, and other factors as they graph the heart rates. Analysis questions help...

Take a field trip to a location where water and land meet to study patterns of sediment organization in wet habitats: river or ocean beaches, sand dunes, tidal marshes, the edge of a pond, or a woodland stream. Small groups collect pairs...

Learn why what goes up must come down in both air and liquids. Investigators discover how convection transfers thermal energy and the movement of particles in liquids and gases due to density differences by viewing an animated video....

Most living things go unnoticed. Change that using a fun activity about the nutrient cycle. Pupils use hula hoops to mark areas of study and then make observations about the living things they see. They first make surface observations,...

Why do athletes load up on carbohydrates the evening before a competition? The instructional activity helps answer this question as it relates the type of food to the amount of energy it contains. After a discussion, scholars...

What do a bird, an egg, a rabbit, and a toad all have in common? This fun-filled resource explains the similarities and differences between cells and how all cells are similar, yet all are different. Learners begin by depicting a...

Teams of Texas tourists gather into groups to analyze what they can do with $50 worth of an alternative fuel. They write checks, keep a balance sheet, and map out their sight-seeing route taking into consideration the location of...

In this scientific investigation activity, students conduct scientific investigations on what happens to the speed of a marble when the height of a ramp is changed, what happens when you add salt to water, and 3 other experiments....

In this lesson, Animal Investigation, 2nd graders will develop investigative and inquiry skills. Students choose one animal as a class to observe. Students ask questions about the animal and record observations, or answers to the...

Students create leaf rubbings as they study the parts of a leaf. They describe the leaves and chart their observations.

Write, edit, and then revise! The fourth lesson in a five-part series asks peers to provide feedback on research. Individuals then use the research to edit and revise conclusions and develop their presentations.

Watch as your class makes the transition from pupils to researchers! A well-designed instructional activity has scholars pick a solar wind characteristic to research. They then collect and analyze official data from the LANL...

Take young geologists on an exploration of the rock cycle with this six-lesson earth science unit on rocks and minerals. Through a series of discussions, demonstrations, and hands-on investigations your class will learn...

It's time to boldly go where your class has not gone before! The introductory lesson in a five-part series takes young oceanographers aboard the NOAA Ship Okeanos to begin a study of ocean exploration. The lesson includes a comparison of...

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

What is a prism? A place for light waves that commit minor refractions! The thorough resource includes three hands-on investigations covering light reflection and refraction; mirrors, lenses, and images; and optical systems. Subject...

Middle schoolers analyze given data on density and diameter of objects in space by graphing the data and then discussing their findings. This ninth installment of a 22-part series emphasizes the Galilean moons as compared to other...
