Limpet Edentification Lab

Don't let the term, "slotted wood board" detract you from the value of this experiment. Class members tie a string to a cart and, with even horizontal force, drag it up an inclined plane. The objective is to compare the work done with...

Computer-interfaced motion detectors are required to carry out this inquiry. It is a new twist on exploring motion with plunger carts: they are set back-to-back and then propelled away from each other. Their velocities are measured, and...

If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels....

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

Students examine fabric. In this Applied Science lesson, students look at the fibers of fabric through a microscope. Students compare and contrast a variety of fibers.

Students create a list of lab safety statements in small groups. They share their lists with the entire class and the entire group decides on at least seven rules, with accompanying reasons for using proper lab safety.

Life science learners view an online animated mini textbook comparing two types of cell division. Working in groups, they use a digital microscope to capture images of cells in different stages of mitosis and meiosis. Then they create an...

Teachers can download this teaching package that discusses the limits on animal size, both big and small, and what effect size has on animals. Students will enjoy the hands-on activities described in the lessons. Teachers will appreciate...

If you've ever had an injection, the horseshoe crab protects you from infection! Young marine biologists discover how scientists use the unique physiology of the horseshoe crab in medicine with a thought-provoking video. The narrator...

Scholars work through three different activities applying their knowledge of total internal reflection (TIR). First, they simply identify which diagrams create TIR and which don't. Next, they match different types of boundary behaviors...
