In this Hess' Law worksheet, students write their data and calculations from the lab they performed on Hess's Law. They calculate the heat of reactions per mole of substances used and calculate the theoretical heat of reaction and...

Students study five of the seven life zones in North America. In this journalism lesson students use the Scientific Method working in teams. They use lab equipment and technology to create a presentation on five of the seven life zones...

In this radon worksheet, students identify the sources of radon in their home and the factors that effect the radon concentrations inside. Students draw a diagram of their house and illustrate potential routes of radon entry. They...

In this chemistry worksheet, students use their workbook to answer short answer questions about chemistry and lab safety. Students complete 7 questions total to get their merit badge.

Middle schoolers explain the benefits and harm caused by bacteria in the body. In this biology instructional activity, students observe bacterial growth in the lab. They explain why anti-bacterial soap may not be beneficial for the human...

Tenth graders observe various chemical reactions in the lab. For this chemistry lesson, 10th graders list the indications that a chemical reaction took place. They give real life examples of reactions they see everyday.

Middle schoolers perform tests in the lab to identify an unknown substance. In this physical science lesson, students observe the physical and chemical properties of substances. They formulate a conclusion based on experimental results.

Students examine solubility and the significance of water.  In this aqueous solution lesson students complete a lab activity on soil profiles.

Students examine Barton's pendulums and watch the video Tacoma Narrows bridge.  In this pendulum and momentum lesson students complete a lab activity, view a video and research a given topic. 

Students develop a device that can measure pH. For this science lesson, students test different solutions and determine whether they are acidic or basic. They write a complete lab report about the process.

How are bubbles made? A simple experiment involving the construction of bubbles is available in this lab worksheet. A fun activity prompts pairs of learners to use dish soap in order to make bubbles. They keep track of the size of the...

Students study pill bugs and their behaviors.  In this pill bug lesson plan students complete a lab activity that includes sketching a pill bug and testing environmental conditions. 

Though the publisher designated this unit for use with third through eighth grades, this particular lesson would be best used with middle schoolers due to the specific measurement skills required. Basically, they set up the reaction...

Now that learners have been exposed to chemical changes, they learn that some take in heat and therefore, decrease in temperature. The same reaction that they have been investigating between baking soda and vinegar is revisited,...

Conclude this chemical change unit by having your class combine two liquids that result in formation of a precipitate. The learners discover that chemical reactions result in new materials. Make sure to consider all of the preceding...

Getting back to the beginning of the unit, learners use reactions with red cabbage juice to determine if solutions are acidic, neutral, or basic. This is a straightforward and classic investigation, but what you will appreciate is the...

Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how...

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

Following this procedure, eager engineers construct a working model of a piston system, similar to that in an internal combustion engine. Perfect for STEM or automotive technology classes, the activity comes complete with analysis and...

Oh nuts! Do macadamias or almonds produce more thermal energy? Energy enthusiasts find out with this experiment. The objective is to demonstrate to your class how the chemical energy contained in foods can be converted into useable...
