Step-by-step building of a catapult from craft sticks; this unit presents the elements of a science project (research, hypothesis, etc.) that can be used for this catapult experiment and applied for other science projects in the future.
An experiment that demonstrates chemical testing by adding a turmeric test liquid to 12 substances. Color changes illustrate whether the substances are base or not. Includes instructions for the experiment and a lab worksheet for students.
A set of four physics experiments in our Where We Find Science series that demonstrate the properties of the surface tension of water. Includes a Scientific Method report form and an explanation and results page.
Build a pond project, part of our "Where we Find Science" series. This project offers opportunities to observe biology in a pond. Instructions for building a pond, plus explanation of possible results and a form for observations of changes in pond are included.
An advanced astronomy project in which student builds a device to measure the position of the sun in the sky and record its changes, to help understanding of seasons. Includes scientific method report form. Part of abcteach's Where We Find Science Series.
An explanation of Archimedes discovery of the formula to measure density of an object using water. Includes directions to conduct an experiment using the Archimedes' method, plus a report form. Part of abcteach's Where We Find Science; Science in Water Series.
A set of two experiments about static electricity, which includes directions, an experiment report form and an explanation of probably results. Part of abcteach's Where We Find Science - Science at Home series.
