Students create an experiment about ozone levels using a Smog City Simulation on the Internet. They complete a worksheet and study associated vocabulary.

Young scholars model the biosphere and manipulate variables affecting change and plan their experiments with the help of others. They describe their question, hypothesis, and methods of investigation.

Learners work in teams of four as they conduct four controlled Jell-O experiments over a two-day period. The Family Page extends this learning to the community by providing families with challenges to explore at home.

Students design an experiment to test the problem of the porridge in Baby Bear's bowl as being just right while the other porridge was either too hot or too cold. They explain the steps of their experiment and record their observations...

Eighth graders biew each volume container and discuss where they have seen them in their home, and how they have seen them used. They explore the different names of volume sizes and their equivalents towards one another. Students...

Students conduct an experiment to determine what type of environment sow bugs prefer. They use petri dishes with partially wet paper towels to assess whether they prefer wet or dry habitats.

Students participate in a lab showing the effects of pesticides on Lumbriculus variegatus. Several extensions and variations are also included in this lesson including one which relates the experiment to how pesticides enter our drinking...

Fourth graders identify variables that influence rates of change. They, through group consensus and using the assigned materials, design and build what they believe to be the strongest mountain possible.

Students conduct an experiment to demonstrate how fruit fly populations are controlled by spiders. They observe a variety of environments with fruit flies and spiders and consider how vital spiders are to controlling the insect population.

Students work in small groups collecting and analyzing data as they learn how to best grow yeast. This lesson allows students to conduct several student-created experiments as they continually generate questions and hypotheses. ...

Students formulate their own hypothesis, determine which variables are important to test their hypothesis, design an experiment in which they collect data. They utilize instruments and tools to measure, calculate, and organize data.

Students create and conduct various experiments to determine the origin of a family artifact, and then determine whether their results were successful. Students summarize their results and evaluate whether their hypotheses were correct.

Students evaluate the importance of hormones in living things. In this biology instructional activity, students experiment on carrots to differentiate how humans and plants reproduce. They collect data from experiment to answer analysis...

Ninth graders observe the relationship between electrical charge and force.  In this electrical charge lesson students experiment and find the quantitative relationship between force and the center to center distance between objects.

Students design an experiment to analyze the timbre of different instruments. In this physics lesson, students analyze the missing quality in sound. They discuss their results in class.

Learners experiment with enzymes as key components of chemical reactions in all living things through this series of lessons.

Young scholars develop and conduct an experiment to answer the question," How does cardiovascular exercise affect the pulse rate?". They record the changes to heart rate during different levels of exercise.

Learners investigate the behavior of pendulums and identify the variables that affect it.  In this pendulum lesson students complete a lab on pendulums, make conclusions about frequency and the period then conduct a controlled...

Learners brainstorm on ways they use water, and where water comes from. They view video, Down the Drain, to gain specific facts about water use, properties of water, problems of water and the water cycle. They perform a lab activity...

First graders learn the basic needs of plants and identify geometric shapes while planting a fall garden. Combining math and science in one lesson, the resource guides kids through starting their class garden as they...

Students take on the role of epidemiologists. They investigate an "outbreak" in serious birth defects that occur in infants born to teenage girls. students discover a link between the use of the acne drug called Accutane and birth defects.

Student observe the effect soap (or detergent) has on the movement of food color in milk. Pupils observe the properties of solids and liquids while making butter. They read a poem, Shaking, and listen for ryhming words. Studdents...

Students collect and graph data and use the internet to research the skeletal muscles.

Students examine what it takes to purchase a car and the resources out there to help find what you are looking for.  In this scientific method lesson students complete different problem solving situations.
