Both aerobic and anerobic respiration are introduced in this succinct PowerPoint. The chemical equations for both are included. The last slides give instructions for a lab activity in which pupils use a gas sensor to measure the...

Amateurs of alternative energy build a mini parabolic-trough solar energy collector and use it to heat water. Temperature is recorded over a three-minute period and the data is graphed and analyzed. Note that in order to paint aquarium...

More than anything, this is great practice in scientific inquiry. After discovering that the color coating of an M&M® dissolves in water during a preceding activity, investigators now question whether or not the color makes a...

Learners examine Boyle's Law by analyzing experimental results with a hands-on lesson that provides a set of four experiments that illustrate the relationship between pressure and volume of gases. Groups analyze results using...

In this endothermic and exothermic reactions worksheet, students experiment with water and a salt of choice to determine if heat is absorbed or released in the reaction. Students take the temperature of their solution over a 2 minute...

Students create a list of things that they do with electrical power. They then are shown a PowerPoint on "Basic Electrical Safety." Students evaluate electrical equipment, cords and situations for serviceability and safety problems. They...

In this chemistry worksheet, students look for the weight of acid and examine its mass using chemical equations and a laboratory procedure.

Students investigate condensation in the lab. In this chemistry lesson, students explain molecular motion during phase changes. They relate this observation to Earth's weather conditions.

Students examine what happens when air temperature drops and gets closer to the dewpoint. They perform a lab activity which illustrates the effects on humidity, precipitation and barometric air pressure.

After taking in background information on teeth, marble, eggshell, and fluoride, chemistry aces design an experiment. Their goal is to demonstrate whether or not fluoride has a similar effect on marble or eggshell as it does on tooth...

This is the grown-up version of the classic "float an egg in salt water" experience, plus an experiment in soap making. High schoolers explore density, but more importantly, practice accuracy, precision, and the use of significant...

What effects do temperature and carbon dioxide levels have on the zooplankton of Antarctica? This concluding lesson plan in a short unit on climate change and the ocean helps environmental scientists answer these questions. After...

Hang a soda can from a string and watch it spin by the force created by water streaming out of slanted holes. This plan provides background information, detailed materials and procedures, discussion questions, a lab worksheet, and...

Middle school science stars observe and record data on the solar radiation reflected off or transmitted through various materials. They predict properties for various materials, and test their predictions by touch. This lesson becomes...

Challenge young engineers to design a one-bedroom scale house to collect and maintain as much heat as possible. Particular constraints must be adhered to, but creativity is also allowed. Included is a diagram and background information...

Using a thermostat is an eco-friendly way to control indoor climate. Young engineers practice building electric circuits by designing and constructing a thermostat. Plenty of background information, a vocabulary list, links to the...

High schoolers comprehend how biotechnology can be used to diagnose infectious disease such as protein technologies vs. DNA technologies. They comprehend procedure and uses of PCR, Western Blot, and ELISA as diagnostic tools. Students...

Students are given some components of an experiment, where they are able to identify and fill in missing parts, such as hypothesis, conclusion, results, etc. They form a hypothesis given general scientific facts. Students apply the...

Get things moving with this extensive collection of physical science resources. Covering the fundamentals of measurement, graphing, lab safety, and experimental design as well as the specific scientific concepts...

Young scholars design and execute a lab through which they study the distinctions between density, buoyancy, and volume.

Although the worksheet for the lab activity is not included, this is an activating activity for your class to do when learning about the greenhouse effect. They lay three thermometers underneath a lamp: one out in the open, one under a...

Students participate in lab activities in which they examine immersion, stain resistance, and stress cracking of synthetic polymers. Students use their collected data to discuss service applications and possible performance of materials.

My room isn't messy — it's a scientific experiment in entropy! Scholars investigate entropy, enthalpy, and spontaneity through a guided procedure and set of questions. The lesson connects the Second Law of Thermodynamics, energy...
