Learners explore linear relationships. In this sixth through eighth grade mathematics lesson plan, students explore the symbolic representation of verbal descriptions of mathematical rules defining the relationship between two variables.

Students are assigned to groups, and determine each member's role in the group. They will design an experiment to determine a way to produce the three primary and five secondary colors. Students discuss color and mood. They listen to a...

Middle schoolers use the scientific method to conduct an experiment and use varied methods to gather background information. They correctly use lab equipment and prepare tables and graphs that organize, conclude, and present their...

High schoolers plan, design, and carry out an experiment to determine an empirical formula for a hydrated salt X that tell students when all the water has been removed from hydrate crystals.

Students design and conduct an experiment to test their ideas about how to speed up or slow down the rate of an enzyme-catalyzed reaction. They have access to an array of physical and chemical factors that might influence enzyme...

Seventh graders hypothesize about the number of drops of liquid that can be placed on a penny before it spills over. They examine both the concept of devising a hypothesis and the idea of surface tension. They determine the difference...

Students design and conduct an experiment to investigate what happens when salt and ice come together and to determine if one form of salt is better for melting ice on steps and sidewalks.

Students review the components of the scientific inquiry method. In groups, they develop hypothesis on a variety of different topics and design an investigation or experiment to test it. They share their conclusions with the class and...

Students determine how speed is measured. In this physics lesson, students design an experiment to find out if the robot's drive wheel size affects its speed. They collect data and discuss results.

Students determine the most appropriate site for a car wash, based on each site's soil characteristics (chemical, physical) and topographic features. They perform an experiment to determine the changes to three different soil types when...

Students conduct an experiment using leaf packs.  For this leaf lesson students complete an activity in groups and complete a handout. 

Students discuss what plants require in order to grow, identify plant parts and their functions and discuss a video about plants. They conduct a controlled experiment with bean seeds and then record and observe the bean plants.

Students explore the factors that affect how long coffee stays hot. They develop a question and a testable hypothesis for one factor such as initial temperature or size of opening of the container. Then they design and conduct an...

Students improve their science skills by designing an experiment for the relationship between electricity and magnetism. In this science skills lesson, students discuss the scientific method and use the given materials to complete an...

Learners answer questions about how microorganisms can affect our food supply and how they can be controlled. The first set of inquiry activities are directed by the teacher. Subsequent activities are based on students generating their...

Students describe the need of plants to have water, soil and sunlight to grow. They use the scientific method when completing experiments. They identify the core democratic values that are needed for a democracy to grow and compare them...

Students examine each soil sample and record observations. In this biology lesson, students design an experiment to test soil flow rate. They write a lab report about the experiment.

Eighth graders design and perform an experiment that uses a Universal Indicator Color Guide to measure the strength of acids and bases. They also determine happens when acids and bases are mixed together. They decide which of three...

Students assemble a classroom river model as an example of a lotic system. They control and measure biotic and abiotic information for the in-class system and compare data with a lotic system in a natural environment.

Students create and conduct experiments on a "classroom river habitat." They manipulate the biotic and abiotic factors so that they are able to compare an artificially prepared river model to a naturally occurring lotic ecosystem.

Students observe the changes between elodea leaves placed in darkness and light.  In this life science lesson, students experiment to find evidence of photosynthesis in elodea leaves. Students use indicators to detect the presences...

Students germinate seeds in unflavored gelatin to which liquid house plant food has been added. Students observe and record plant growth in this medium with a variety of variables in a number of experiments.

Students identify the control and the variables in the experiment. They describe the growth of plants with and without nitrogen fixing bacteria, then name the bacterium responsible for making nitrogen available to the plant.

Students describe the roles of controlled, manipulated and responding variables in scientific research. They also identify biotic and abiotic interactions affecting the makeup of a plant community.
