Young scientists discover the importance of scientific investigation by observing live crayfish. They carefully observe the patterns of crayfish in different environments. Then they discuss their conclusions and define what all living...

Kinematic equations are used to calculate the velocity and momentum of different types of balls bounced on different surfaces. The lesson plan is detailed and provides a materials list, background information, and procedures....

How do different minerals affect the growth of plants? Budding botanists find out in a multi-week experiment that has them using solutions with specific mineral deficiencies. While there is a lot of preparation for the investigation,...

Does your cat sneak up on you in the middle of the night? Maybe it would help if he glowed in the dark like Mr. Green Genes, the first fluorescent cat in America. In a fun and engaging lesson about genetic engineering, high school...

Physical or life science learners measure the amounts of water eliminated by intestines and the urinary system, and the amounts lost via respiration and perspiration. In doing so, they discover that the body's water must be replenished...

Like good scientists, kids often want to see first-hand why things are as they are; they can do just that in the starch-testing photosynthesis activity found here. Depending on the age of your pupils, you may wish to do the investigation...

In a mini-lab, the class will prepare Hawaiian Haystacks to eat. A note-taking worksheet is included for learners to use during a PowerPoint presentation about six basic dietary guidelines. Most of the time required for this activity is...

If your future physicists know how to construct simple circuits, include resistors, and use a multi-meter to measure voltage, then you might employ this lesson on Ohm's law. Each lab group investigates the relationships among...

In this simulation activity, young biologists examine blood types to determine whether the death rate in a hospital was caused because of incorrect identification of patient blood types. You will need obtain and follow the procedures of...

Demonstrate how ice floats on water and get the class thinking about why icebergs are so deceiving. Investigators then experiment with mixing water of the same temperature and water of different temperatures. Make sure to explain the...

Go through the proper steps to setting up and conducting an interview as part of research. Slides detail preparation, materials you should have, and follow-up procedures. Specific questions for the interview are not suggested but the...

Suitable for an AP Biology class, the lab found here has teen bioengineers working with plasmids to clone DNA. If you have not done a similar lab, the instructions may be rather difficult to follow. Both the teacher and learner...

This lab sheet gives a detailed procedure for your class to find the mass of Butane.  There is a complete guide for calculations, data analysis, and conclusion.

Students will determine the direction of Earth's rotation as viewed from the north and south if they were suspended out in space. They will model how the rotation of the Earth causes currents to be deflected in different directions for...

Students examine the effect of temperature on how often crickets chirp. In groups, they complete the experiment and answer lab discussion questions. They create a graph of temperatures and the amount of chirps and discuss the results.

In this microbiology worksheet, students complete 9 review questions after finishing a group lab in which they perform four biochemical tests to help divide the Enterobacteriaceae into two major groups- E. coli and...

In this biology worksheet, students identify the different types of reagents being used with the samples as part of an extensive lab experiment.

Fourth graders complete activities to study weather and the water cycle. In this water cycle lesson, 4th graders observe a demonstration of the three stages of water. Students work in groups to complete a water cycle lab activity....

In this membrane permeability worksheet, students read introductory information about the cell membrane structure as it pertains to permeabillity and draw a representation of the membrane as they complete a lab. Students record the...

Students examine the steps and safety procedures in the cheese making process. They make and taste a variety of cheeses comparing their properties.

First-time physicists experiment with pendulums in this physics lesson. They vary the weight of the bob, record how long each takes to complete ten period swings, and then calculate the time for one period. They repeat the procedure,...

Here is a lab that has teenage scientists examining samples of their own blood under a microscope. Learners carefully prepare slides, then make detailed observations and identifying different types of cells using a key. 

For any science class, learners can use this lab sheet to plan an experiment. It includes a space for the title, question, materials, setup, and procedure. If you want your class to complete this in typed form, you can provide the web...
