Students conduct a lab to determine the best way to separate a variety of mixtures choosing between paper, thin layer and column chromatography. They use chromatography techniques to identify unknown substances and submit a lab report on...

Learners build a Lego design and then work with a partner to reproduce that design. They guide the building of the reproduction by description only and then check their work.

Students listen to a lecture on four factors that influence microbial growth and they discuss how to test the optimal growth requirements of a designated bacterium. They design and carry out laboratory investigations to test growth of...

Students work collaboratively in small groups to create and edit various publications to promote their school's activities and accomplishments. Groups work to complete these publications and publish or update them bi-monthly.

Fourth graders participate in a scientific experiment involving growing lima beans. Students plot information gathered on included charts and graphs. Students use the steps of the scientific method throughout this experiment.

Eighth graders practice technology skills through the use of a spreadsheet and a discovery lesson focusing upon linear equations. The technology allows for the visual changes to be displayed for different lines of equations.

High schoolers conduct simple sampling of plant and insect biodiversity at ground level in two contrasting environments of their own choosing. They recognize and record different species then compare and contrast species numbers in the...

Students observe, measure, and sort tree leaves. They examine leaves individually, in groups, and in relationship to the entire tree. Pupils take a walk outside for a "Leaf Walk." Students are each given a lunch size paper bag, so that...

Students demonstrate the attraction of small pieces of paper to a charged plastic rod and conduct experiment with other objects to determine whether they can hold a charge. They then use online applets to apply their experiments to...

Eighth graders discuss the forms of heat transfer that relate to the human body. Discussion revolves around the ability of different designs of hats to change the rate of heat transfer to and from the body. Students then experiment...

Seventh graders design and conduct experiments to determine what environmental factors favor decomposition by soil microbes. They use chunks of carrot for the materials to be decomposed, and their experiments are carried out in plastic...

Learners conduct an experiment mimicking a hardness test. They determine the hardness of chocolate bars. Students examine indentations to determine the hardness of chocolate bar and infer reasons for the differences in hardness. They...

Students experience a guided inquiry into the workings of an ultrasonic motion detector. They are led to study something they cannot see, hear, feel or taste. Students design strategies to avoid becoming prey of the predatory "Batzilla."

In this word search activity, students locate words related to biology. The word list includes protists, viruses, plants, spiral, and biotechnology.

In this where do plants get their food worksheet, students design an experiment that will disprove the idea that plants obtain their food from soil. Students will set up their experiment and design a data table that will record data over...

For this DNA worksheet, learners access a website to determine the information that was used to understand DNA replication. Students compare the difference between observations and opinions. This worksheet has 7 short answer questions...

Students examine the three different types of soil and their physical properties.  In this soil lesson students design and implement a model of a water treatment plant. 

Students explore methods for reconstructing the past. In this forest succession lesson plan, students examine forest succession and how to read the land in order to predict patterns of change. Students will visit a historical site, act...

Students study how to better their cohesion and communication skills.  In this investigative lesson students work in teams and learn how to communicate better as they help to solve problems and communicate their needs.
