Solar Kit Lesson #14 - Solar Cells as Control Devices
Given four suggested concepts, emerging electrical engineers research, design, and constuct a working device that willrespond to changes in the intesnisty or the direction of sunlight. This is a challenge for learners to rise to, as the...
Curated OER
Elastic Recoil in Arteries and Veins
A lab in which high schoolers examine the difference between arteries and veins. Budding biologists will find out which blood vessel can stretch furthest, recording their data in a table then answering several questions evaluating their...
Crash Course
Calorimetry
When the chemists who designed hand warmers were working, they had to consider how much heat they could give off to keep people warm — and not burn anyone in the process. How is this heat given off in a chemical reaction measured?...
Texas State University
Earth: Deposition and Lithification
Geology geniuses analyze sediment samples with a hand lens and sort according to physical characteristics. They also learn about the processes of cementation, compaction, and lithification within the rock cycle. The lesson plan is...
Curated OER
Solar Kit Lesson #8 - Positioning Solar Panels II: Explorations with Stationary Panels
This lesson is preparation-intensive, but well worth the investment. You will construct five or six portable testing stations with which lab groups will gather data on the best position for collecting sunlight with a solar panel. This is...
Curated OER
Drug Analysis Using Thin-Layer Chromatography
Students use forensic science to positively identify any suspected drugs submitted to the laboratory. They determine the identity of the drugs found in the bodies of drug-overdose victims. Students use TLC to identify the active...
Curated OER
The Greenhouse Effect
Why does it get so hot inside of our cars in the summertime? The greenhouse effect! Lab groups experiment to see what happens to an ice cube enclosed in a jar and placed in sunlight as compared to an ice cube outside of the jar. They...
Curated OER
Solar Kit Lesson #1 - Solar Cell Inquiry
Give youngsters the components of a solar-powered electric circuit and turn them loose to figure out how to connect them in order for a light to shine or motor to turn. They compare energy output of a solar panel to that of a battery. On...
Curated OER
Solar Kit Lesson #6: Solar-Powered Battery Charger
In a previous lesson, learners build an ammeter. That ammeter, or a pre-made one, is required in order to carry out this lesson. The objective is for lab groups to design a way to connect solar cells that can recharge a battery. Basic...
