Students are told that an air tank contains a fixed volume of air under pressure. As air is used, the pressure decreases at a rate that depends on the depth. Students discuss how SCUBA divers calculate the amount of time they can spend...

The scientific method is emphasized in this engaging and exciting chemistry lesson. Learners get to create Alka-Seltzer cannons out of film cannisters, water, and Alka-Seltzer tablets. Carbon dioxide gas builds up inside the cannister,...

Students are introduced to the processes of evaporation and condensation as they observe physical changes in water. They observe how matter changes from a solid to a liquid state. Students are explained that steam is water in its gaseous...

Students investigate the properties of air through inflated objects. In this physical science instructional activity, students examine gas as a state of matter. Student push on inflated objects and note the space the gas has taken up...

High schoolers explore Boyle's Law. For this Boyle's Law lesson, students complete problems involving Boyle's Law. They examine the effects of Boyle's Law upon the human body. High schoolers use the Internet to complete a lab activity.

Build an air lift siphon using your mad physics skills! Learners first investigate the importance of circulating water in aquaponics systems. They then use density to their advantage as they engineer an air lift siphon

My forecast is that you'll want to use the resource. Pupils design and create a weather bot as part of a project-based unit. These bots should be able to measure temperature, humidity, barometric pressure, wind speed and direction, and...

Students study the gas laws in particular the three variables; pressure, temperature and volume.  In this gas laws lesson students complete an activity and discuss their findings. 

Students work in a mini lab where they measure the temperature every 30 seconds for several minutes as water is heated. They are asked what makes liquid different from a solid. Students view a PowerPoint on the model of liquids,...

Students discover simple gas laws by observing an egg sucked into an Erlenmeyer flask. When the flask is warmed, the egg is placed atop it. when both are placed in ice water, the egg slips into the flask. The procedure is then reversed....

Students apply the ideal gas law and Dalton's Law of Partial Pressure to develop an experiment which determine the molar mass of butane from disposable lighters. In small groups, they develop a procedure and have it approved before...

Students investigate the properties of air by capturing it, squeezing it, and feeling its weight. In this forces lesson, students capture bags of air and examine its properties. The weight and pressure of air is emphasized.

In this experimental relationship worksheet, students read about direct and indirect relationships between variables in experiments. They answer three questions about relationships between variables.

Students discover the principles of solubility and phase state and their influence on chemical phenomena observed around deep-sea volcanoes. They describe the effect of temperature and pressure on solubility of gasses and solid materials.

Students explore how clouds are produced through three different age-appropriate hands-on experiments.

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Young scholars explore how principles of gas behavior relate to diving in order to plan safe underwater activities.

Students observe water change from a liquid to a gas state when heated and then return to its liquid stage when cooled. They learn that gas molecules move faster than liquid molecules. They discover physical properties that describe how...

Fifth graders watch a demonstration in which a balloon is inflated using the gas created by combining vinegar and baking soda. Then, in groups, they combine various assigned substances and watch and record the results.

In this physics review worksheet, students complete 24 matching and problem solving questions pertaining to math code, speed, experiments and variables, slope, and acceleration and average speed.

In this chemistry worksheet, students calculate the freezing point of a given solution. Students calculate the final temperature and state of the water in a given problem. Students solve several problems provided.

Young scholars investigate the carbon dioxide content of different sodas. In this chemistry instructional activity, students explain why PET containers are preferable than HDPE for soda bottles. They collect data and graph them.

Students discover that scuba diving is more than a sport. It's a science that operationally integrates physics, chemistry, physiology, and oceanography. They perform a simple experiment which simulates the air tanks used in scuba diving.

Students define several laws of pressure and see how they relate to scuba diving.  In this ocean explorer instructional activity students answer questions and complete an activity.
