Students investigate, through a hands-on activity, in which type of soil a bean seed grows best. They create a bar graph representing each plant's growth in different soils.

Students are involved in hands-on activities to determine how course conditions affect bobsled, luge, and downhill ski races.

Eighth graders collect data from Bottle Biology compost columns and record using Excel spreadsheet.

First graders make ice cream and determine what makes this liquid turn into a solid.

Find out what variables are in a scientific investigation and what the difference is between an independent, dependent, and controlled variable. Look at samples of different types of variables and find out what makes a good variable.

By making a simple sled kite from the template provided and using the suggestions in the Science Buddies project, you can experiment with variables that test different aspects of flight. The Science Buddies project ideas are set up...

Plants have evolved many clever mechanisms to ensure that their seeds will wait for appropriate conditions before sprouting. Some may only germinate after a fire, others only after going through a cold spell. This project explores one...

Students investigate the best way to cushion wrap a sugar cube to protect it from a collision in this lesson plan. During their investigation, students learn about collisions and variables that affect collisions.

In this activity, you will be able to observe the oxygen production in leaves by doing a floating leaf disk experiment. You can also find out how quickly plants produce oxygen, and what variables affect photosynthesis.

[Free Registration/Login Required] This flipchart gives a guideline for planning and conducting science experiments. It gives an organized approach to planning, obtaining evidence, presenting and evaluating the results.

Hunkin's Experiments is a group of simple cartoon illustrations of scientific principles. Some would work well in the classroom, but others have little value beyond entertaining students. All of the projects are easy to do and use...

Take this self-checking, five question practice quiz over various methods of science.

Students are challenged to design a way to drop a raw egg from varying heights without letting the egg break. Creative thinking and evaluation of results are critical to the project.

This site explains genetic beliefs before and after Mendel, and also includes a section on Mendel himself and his experiments, entitled, "The Monk and his Peas".

This site is provided for by Michigan Reach Out. Students experiment with the variables of force, pitch and volume after making a drum.
