A lesson on states of matter using marbles for molecules expands into 3 more lessons elaborating on properties of a gas.
This is a teacher demonstration used to show an example of kinetic molecular energy using food coloring and water. The students are also given opportunity to develop their own questions and tests.
This activity provides for small group investigation of the properties of different liquids leading to the discovery that liquids are different in many ways, including density.Students would be led to a very beginning understanding of density.
This lab activity is designed to have students use their knowledge of balancing and identifying chemcial reactions and apply it in a fun and interesting way!
In this lesson, students first create factor posters for a variety of different numbers that will be displayed in the classroom to be utilized as a resource throughout the school year. They make discoveries about factors using color tiles, represent their discoveries using graph paper, and display their information on poster board as find factors of an assigned number. The plan includes a list of materials, questions, assessment options, and extensions.
This is an interactive applet game exercises a student's factoring ability. A student can play against the computer or against a friend on grids containing the numbers 1-30, 1-49, or 1-100. Each player in turn chooses a number from the board, and then the opponent claims all of its remaining proper factors. A player's score is the sum of all the numbers and factors she/he has chosen. When there are no numbers remaining with unclaimed factors, the game ends and the player with the greater total is the winner.
An online, interactive, multimedia math investigation. The Factor Game engages students in a friendly contest in which winning strategies involve distinguishing between numbers with many factors and numbers with few factors. Students are then guided through an analysis of game strategies and introduced to the definitions of prime and composite numbers.
When students play the Factor Trail game, they have to identify the factors of a number to earn points. Built into this game is cooperative learning students check one another's work before points are awarded. The score sheet used for this game provides a built-in assessment tool that teachers can use to check their students' understanding.
This interactive applet allows a student to visually explore the concept of factors by creating different rectangular arrays for a number. The user constructs the array by clicking and dragging on a grid. The length and width of the array are factors of the number. A student can elect an option of a randomly selected number or the student selects his own number between 2 and 50. Exploration questions are included to promote student discovery of mathematical concepts with factors.
This lesson is a presentation of famous scientist throughout history where the students will learn and take notes about the contributions and discoveries made in science.
Play with a bar magnet and coils to learn about Faraday's law. Move a bar magnet near one or two coils to make a light bulb glow. View the magnetic field lines. A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude of the current. You can also play with electromagnets, generators and transformers!
Light a light bulb by waving a magnet. This demonstration of Faraday's Law shows you how to reduce your power bill at the expense of your grocery bill.
Students study an ancient bronze statue, analyze its pose, and discover how conservators remove and prevent corrosion. They learn that the bronze used to make this sculpture is an alloy of copper and tin with small amounts of antimony, lead, iron, silver, nickel, and cobalt. They use the periodic table to research the chemical formulas of compounds used to make bronze. After learning about oxidation-reduction reactions that occurred in the statue, students speculate about the conservation techniques needed to conserve the bronze sculpture.
Students study an ancient bronze statue, analyze its pose, and discover how conservators remove and prevent corrosion. They learn that the bronze used to make this sculpture is an alloy of copper and tin with small amounts of other elements. They use the periodic table to research the chemical formulas of compounds used to make bronze. Students compare conservation techniques in two ancient bronze objects.
Students can use this interactive Flash applet to practice subitizing and counting groups of objects, to understand the importance of 5 in our base-10 number system, and to learn basic addition facts. In the four included games students construct groups of 5 objects, add groups of objects within 10, and identify and record numbers within 10. Auditory prompts support students with limited reading ability.
This activity is an observation lab where students observe the colors emitted by various metal ions in salt solutions.
This is a classroom lab where students will explore the concept of density by investigating how various solids and liquids interact.
This activity is a guided inquiry activity where students take simple measurements and use unit analysis to determine the thickness of a sheet of aluminum foil, the volume of an aluminum atom, and the radius of an aluminum atom.
Explore the forces at work in a tug of war or pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.
In this lesson designed to enhance literacy skills, students learn how the forces of gravity and air resistance affect the motion of falling objects.
