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.
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 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.
This great introduction to the importance of indicators is a science experiment, with different levels of questions presented for each grade level from kindergarten to middle school. Clear, thorough, and fun explanation of acids and bases.
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 seven experiments that demonstrate that the sciences of biology, chemistry and physics are part of our life at home. Set 1 of a series of experiments titled Science at Home, includes a description of experiments, scientific method report form and an explanation of probable results.
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.
