Many ZOOM into Engineering (elementary and middle school level) experiments are available in Spanish in addition to English. See http://pbskids.org/zoom/printables/activities/ and look for the ESP designation. This site provides handouts in PDF format that you can print out and take to the classroom. All of the instructions are included, just check and see what supplies you will need and your visit is practically planned! Some example are attached below.
High school experiments
Transistor experiments
Objective: With this experiment, students will learn more about how transistors work, how they are used to make decisions and how see some example applications
Terms to understand:
Transistor: This is the basis of any electronic device you could mention that you have in your home, school, car, computer, games, etc. In most cases, it is really a simple switch which is either on or off, like answering a question, yes or no. The simple model of a transistor is shown below: 
Software protocol
|
Objective: To illustrate how computers communicate large amounts of information over a single wire or communication channel Terms to know: Protocol: A set of rules that are used to accomplish a task more quickly, more efficiently and more reliably. Handshaking: An indication that the current task has been completed. An example would be acknowledging the receipt of a piece of e-mail by sending back a reply. |
Mouse trap vehicle
Supplies:
- 1 Mouse trap (rat traps are even better!)
- Toy wheels (either with small tacks/nails or on axles) - up to 4
- string
- elastics
- Elmer's glue
- odds and ends (toothpicks, small sticks, thread spools, small blocks, etc.) ÂÂ
Procedure:
Materials under stress
Experiment 1: Materials Deform Under Stress
In this exercise, we will explore the behavior of elastic bodies under load, identifying parts that are under stress (compression or tension). In the following steps, observe the space between the grid lines on the flexible (elastic) urethane foam beam. 
Refer to figure 1 as you perform the following experiments.
Build a bridge
The following is an activity that I tried with a class of 8th graders last year that proved successful and fun.
Activity: Engineering a Bridge
Time required: 50 minutes
Objective: Allows students to experience what it is like to participate as a member of an engineering design team to complete an engineering project within a specified budget and schedule.
High school experiments
These experiments are suitable for high school students.
