Students examine how gravity affects launching rockets into space. In this physical science lesson, students review the concept of gravity and use an interactive online site, "Gravity Launch," to simulate a rocket launch.

Students conduct a hands-on experiment with collisions between two skateboards of different masses. They are introduced to the concept of conservation of momentum in collisions and consider how their observations might help engineers...

Middle schoolers work in groups to conduct experiments the demonstrate the differences between static and kinetic friction. They consider how friction affects us in our everyday lives, determine the effects of weight on friction and...

Students investigate technology and make a correlation between technology and the weather. In this science instructional activity, students experiment with the weather and climate using technology to help them understand forces and...

Students explore the water cycle. In this earth science lesson, students observe and measure water in a closed container and in an open container. Students record their observations and compare their sets of data to draw conclusions...

Young scholars discover how seeds travel from their parent plants in search of water, sunlight, and nutrients, and conduct experiments in which they note characteristics that encourage seed dispersal by means of wind, water, animal...

Students perform an experiment to determine the stomaltal index on the upper and lower epidermis of two species of leaves. Stomatal densities change in response to changing atmospheric levels of carbon dioxide and to annual rainfall.

Students perform an experiment to demonstrate the principles of antibody-antigen binding, the secondary immune response, cross reactivity, and complement fixation. The materials to be used include antibodies from a rabbit that was...

Students conduct and observe experiments in Newtonian mechanics, kinematics, and projectile motion. They analyze the motion of a ball rolling off a table, falling, and then bouncing. Students answer a series of questions analyzing the...

Fifth graders experiment with student-made aluminum boats to test for buoyancy. They design a boat and determine how many marbles it takes to sink it while recording their data in a spreadsheet. They design a graph using the data and...

Fourth graders explore the concept of echolocation during a unit on whales. They listen to the book and watch the Reading Rainbow video for "Humphrey: The Wayward Whale," explore various websites, and conduct experiments to demonstrate...

Eighth graders participate in an experiment that emulates a sonar signal bouncing off the ocean floor. They determine how the ocean floor is measured by the length of time it takes for the sonar signal to return. They work with a wooden...

Students watch the teacher do a demonstration of density with diet and regular soda. Note: try this first, as different types of artificial sweetener have different densities. Students discuss density and volume. They discuss "Relational...

Learners research and define a muscle biology research question and organize an experiment to address the question utilizing either NADH staining or acid buffering. They analyze data as well as draw conclusions about their research....

Young scholars investigate what a calorie is and how and why we measure them. They conduct an experiment to compare the calories of a peanut and a mini-marshmallow, and explain and discuss how calories are directly related to the amount...

Students identify the investigator whose studies formed the basis of modern genetics (Mendel). They list characteristics that make the garden pea a good study organism, and summarize the 3 major steps of Mendel¿¿¿s experiment.

For this biology worksheet, students identify and define the vocabulary terms listed and make a prediction about the outcomes of the experiment. Then they complete the chart of the observations of the plankton diversity in drops of pond...

In this scientific methods worksheet, students identify the control group, independent variables, and dependent variables in 4 different experiment descriptions.

In this experimental design activity, students are given two experimental scenarios to read. They answer questions about each including finding the hypothesis, the independent and dependent variables and controls. They design a graph for...

In this alchemy worksheet, learners read about how alchemists kept their experiment notes in secret code. Students design their own secret code for the given elements. This worksheet has 2 problems to solve.

Students experience the life a spider through several cross-curriculum activities that address multiple learning styles. In this cross-curriculum lesson, students listen to The Very Busy Spider by Eric Carle and toss string in a circle...

In this volumetric analysis worksheet, learners determine the relative molecular mass of an unknown group 1 carbonate by experimenting with a known amount of hydrochloric acid. Students use volumetric analysis to determine the moles of...

Seventh graders identify variables and controls in a paper airplane investigation. In this scientific method lesson, 7th graders conduct an experiment to determine the variables that affect the flight of paper airplanes. They design an...

Students study the water cycle including condensation, evaporation, and precipitation. In this water cycle instructional activity, students watch a video and access assigned web sites to investigate the water cycle. They complete an...
