In this lab activity, students investigate differences in ocean water density. Students record density data from salt, ice, and hot water samples in their notebooks. Students then simulate ocean water temperature levels in a graduated cylinder, extending density knowledge by introducing oil as a pollutant.
In this STEM activity, students are provided with a variety of materials to build a hot air balloon. Teams of students will use their knowledge of density and heat transfer to design, construct, and test their balloon. The activity concludes with flight testing the balloons and then a review of the design features of all balloons for the most advantageous design features.
In this activity, students use the scientific method to design a paper car that will travel down a ramp on its own. Then they will use the car to investigate and calculate speed.
In this activity, students design their own airplanes and fly them. The challenge is to create a fast plane and a slow plane and compare the speed to the design. Students will hypothesize and test which factors affect the speed of the plane (e.g. mass, shape, force thrown, etc.).
In this activity, students will measure the rate at which the photosynthesis process occurs. Students will work in small groups to design an experiment with one independent variable and test this variable on spinach leaf disks.
In this activity, students will discover the magnet's field where the magnet can exert its power to push or pull.
In this lesson, students are introduced to normal seasonal sea surface temperature (SST) variation as well as extreme variation, as in the case of El Niño and La Niña events, in the equatorial Pacific Ocean. They will learn how to download seasonal SST data from the Pacific Marine Environmental Laboratory (PMEL), via a THREDDS server, for the years 1982 to 1998. With My World GISTM, they will visualize and analyze that data, looking for the tell-tale SST signature of El Niño and La Niña events that occurred during that time period. At the conclusion of the chapter, students will be given the opportunity to analyze a season of their own choosing to determine if an El Niño and La Niña SST pattern emerged in that year's data.
In this lesson, students develop an understanding of the relationship between pressure and volume of a gas. They will determine a mathematical formula for this relationship, practice data collection and graphing skills, and make the connection between force and pressure.
In this lab activity, students observe the effects of temperature change on the color of nitrogen dioxide and dinitrogen tetroxide by manipulating glass tubes containing the gases at equilibrium. Students are then challenged to figure out how to impose the stress of temperature change on the gas tubes using a limited set of provided equipment. Students will also write a balanced equation for the reaction and correctly determine the color of nitrogen dioxide gas.
In this activity, students will "dig" for paper fossils and make observations of various fossils to determine characteristics of chimpanzees and humans. Students will then use their new knowledge to dig up and analyze a new fossil discovery that must be presented, with evidence, to the scientific community (class) during and oral presentation.
This activity will allow students to analyze a direct measurement video clip of a blow dart colliding with a cart initially at rest. Students will be able to make measurements directly from the video that will allow them to investigate physics concepts such as velocity and conservation of momentum.
This activity is intended for an entry level algebra-based physics course in the chapter of forces in two directions. The objective of this lesson is for students to use a direct measurement video to calculate the coefficient of kinetic friction of a block sliding down a ramp. This video is best used after the students have a good grasp of forces in two directions, and the students must have prior experience with direct measurement videos.
In this short lab, students will observe the acceleration of a object as it initiates acceleration, maintains a steady speed, and slows to a stop. The student will diagram the motion of an accelerometer (a bubble level attached to the object).
In this data-based activity, students gather data as a class from a person running at different rates on a football field. Synchronizing stopwatches and placing students every 10 yards apart as a classmate runs down the field and data is collected. The students then share the data as a class and transfer it to any graphing program. Once graphed, the entire class has the exact same distance versus time graph. As a class we then discuss what was happening between various time intervals, record in words what the graph is showing, and calculate average velocity.
In this lesson, students will investigate how land is used for mining. Students will mine for "ore" and observe damage to the surrounding land. Students will then have the opportunity to reclaim the land by filling in the holes and they will observe how the land has changed.
In this multi-age lesson, students will work with an upper elementary partner to collect and observe soil samples from the school grounds. They will divide a paper plate into four sections and label them animals, pllants, rocks and other and dissect their soil, placing what they find on the labeled paper plate sections. At the end of the lesson, students discuss as a group what they found in the soil.
In this unit students will learn why it is important to study drought.
