Scientists used flame tests to identify elements long before the invention of emission spectroscopy. Young chemists observe a flame test of five metal cations in the fourth instructional activity of an 11-part series. Individuals then...

Chemists consider a situation in which an ethanol producer needs to determine how much to add to t-butanol to prevent freezing during transport. They work in the laboratory to obtain the freezing point depression constant for the...

This is actually a 10-day mini unit on thermal energy for your high school chemists. Every avenue is taken to get learners absorbed in heat: a pretest, a PowerPoint presentation, Internet exploration, demonstrations, lab activities, and...

There's more to fluids than meet the eye—they include gases, liquids, and polymers, too! Scholars complete three hands-on activities exploring different properties of fluids. They explore viscosity by measuring the resistance, or...

You're bound to get a reaction from your classes with this experiment! Scholars perform several chemical reactions, make observations, and classify the reactions as single replacement, double replacement, composition, or decomposition...

I'm so cool! No, you're exothermic. This thermodynamics lab unit includes an introduction, teacher demonstrations, six labs that students rotate through each class day, homework assignments, application of knowledge, and...

These rocks are HOT! Well, they used to be, anyway. Take young geologists on a two-week journey through the life and times of the average igneous rock. Lab groups work together to hypothesize about intrusive and extrusive igneous...

Students preview a copy of the lab experience and "cookbook translator" prior to the actual lab experience. They participate in the lab experience and complete the "cookbook translator" for evaluation at the completion of the laboratory...

Students participate in a lecture and lab explaining the qualities of a casserole, identifying the different kinds, the function of the ingredients and foods used in the preparation of the casserole.

In this radish seed worksheet, students fill out a lab packet having to do with radish seeds. Students answer short answer questions, charts, and draw graphs of their results.

Eighth graders watch a Lab Safety video and discuss particular questions related to lab safety. Lab equipment is then distributed and the students inspect the equipment and record their finding in their journal. Finally, in groups, 8th...

Students discover the components of primary and secondary colors. In this physical science lesson, students create a set up in which water will separate a color into the component colors along a piece of filter paper. Students will...

Students explore the predator-prey interactions and how humans have an impact on the food web.  For this food lab lesson students complete a food web activity and discuss what they learned. 

Looking for a project to use in an AP® Computer Science class? Engage learners with a simple solitaire game called Elevens. Through these activities, learners break down the task and write the code for a game. Sign in to your College...

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...

The first capacitor was a Leyden jar, invented in 1745. Physics scholars explore capacitors in an engaging simulation. They may view one or set up circuits which contain two to three either in series or parallel. Other views include...

How would a pendulum work on the moon or Jupiter? To answer that question scholars control up to two pendulums including their location, length, mass, and amplitude. Added controls include changing the friction and strength of gravity....

Does size or mass impact gravitational pull? Scholars experiment with force pairs to answer that question. They can change the size, mass, and distance between the objects using an engaging simulatoin. This allows pupils to visualize the...

Can our energy resources keep up with our ever-growing population? Science scholars learn the basics of energy and Earth's energy resources during an electrifying instructional activity. The resource combines video clips and an...

It's important to protect yourself online. An online game has pupils imagine themselves as cybersecurity specialists at a social networking company. They learn about ways to protect data online through a series of challenges.

Don't be fooled by cyber scams! An informative lesson teaches techies about cybersecurity. They watch videos, play a game, and engage in discussion to improve their understanding of online safety.

A sign that washed away from Hurricane Sandy in 2012 beached itself 3,595 miles away in France. This artifact and others from around the world help scientists understand water currents and the far-reaching impact of hurricanes. Scholars...

The intent of this series of activities is to introduce high schoolers to the field of chemical instrumentaiton. They perform a few basic chemistry lab techniques: pH titration, paper, gas, and liquid chromatography, ultraviolet and...

Advanced lab apprentices prepare zinc and copper solutions to which they will compare the same minerals from a multivitamin. Using absorption spectroscopy, they analyze the contents of the multivitamin for concentration. This lab can be...
