Make a Speaker

In this activity, students will learn how an electromagnet works by making a simple one. Using this knowledge, students will design a diagram to make a working speaker using household materials. Then students will follow instructions on one method of making a speaker, and test their own designs to compare results.

Building A Solar House

Buildings that are called “green” or “environmentally sustainable” are designed to use energy as efficiently as possible. In Missouri, Washington University’s Tyson Living Learning Center achieves sustainability by incorporating green technologies in different ways, including the use of solar panels. In this activity, students will explore how solar panels work by building a simple circuit, a series circuit and a parallel circuit, using a solar panel to light a bulb and comparing which method yields the brightest light. Then students will build a solar-powered house using a shoebox, and test some variables to determine the most efficient way to harness solar energy to power a model home.

Grabbing a Bite to Eat

In this activity, students will perform an experiment that replicates the dilemma that birds face in acquiring food from a confined area. Students will be given a variety of objects to use as “tools,” and will explore various ways of extracting the food item from an enclosed shoebox without directly using their hands. Students will compare and contrast which tools worked best, and use problem-solving skills to design and develop unique methods for extracting the food item from the shoebox.

Flower Anatomy

In this activity, students will discuss the various methods by which pollination can occur in flowers or plants. Students will dissect and identify the different parts of a flower, hypothesize the function of each part, and discuss the importance or relevance of each part to pollination.

The Color Of Flowers

In this activity, students will perform an experiment to find out where flower colors come from. Students will extract petal juice, use acid and base indicators, and observe chemical reactions to investigate how the amount of acid or base influences the color of a petal.

Lighting Up Celery Stalks

In this activity, students will conduct a series of hands-on experiments that will demonstrate how the working of these veins, known as capillary action, enables water to travel throughout the length of a plant. Students will learn how the forces of water cohesion and adhesion contribute to the process of capillary action.
