Equations for Curves Passing through a Given Set of Points
Learner use three random locations on the coordinate system and simplify the expression and assign result to the variable loc. They substitute guesses for the center and radius of the circle in the equation for the center of a circle and plot the result and solve for the radius, and the coordinates of the center.
The Cylinder Problem
Students build a family of cylinders and discover the relation between the dimensions of the generating rectangle and the resulting pair of cylinders. They order the cylinders by volume and draw a conclusion about the relation between dimensions & vol
Circles, Circles, Everywhere!
Young scholars explore the concept of circles. In this circles lesson, students use their Ti-Nspire to collect data on various circles of different sizes. Young scholars measure the diameter and circumference of the circles and plot the data in a scatter plot of diameter v. circumference. Students find the slope of the line to be Pi.
Size of Atoms - Trends
This compendious collection of slides leaves no questions when it comes to the concept of atomic size. Thorough and easy-to-read graphs, tables, and graphics explain atomic radii, the shielding effect, the octet rule, isoelectric species, and electron-dot notation. There is enough material here to support more than one day's worth of lessons for your budding chemists.
Investigating the Sine and Cosine Functions
Students explore the concept of sine and cosine. In this sine and cosine lesson, students collect data from a unit circle about sine and cosine values at different angle measures. Students graph the sine and cosine data on a coordinate plane to discover the shape of the sine and cosine function.
New! Circumference & Area Worksheet 3
You can't go wrong with this series of practice problems about circumference and area. The answer keys are provided, so you can use some or all of the problems without needing to worry about solving beforehand. Some problems have your learners plug in the radius or diameter while others ask them to solve backward for the radius or diameter. Good for use as an assessment as well.
New! Circumference & Area Worksheet 1
Don't stress about creating your own problems and use this series of circumference and area worksheets. The problems ask pupil to plug diameter and radius into the formula to solve for area or circumference. The problems also have learners to work backward and solve for the diameter and radius when given the area or circumference.
New! Circumference & Area Worksheet 2
With plenty of problems to chose from, this series of worksheets provides you different types of area and circumference problems. Your learners can plug diameter and radius in to solve, or they can work backward when the area or circumference is given. No formulas are listed on the page, so this can be used as an assessment.
Math 7/8 Review for Formulas, Area, Surface Area, and Volume
In this area, surface area, and volume learning exercise, students solve 19 short answer problems. Students find the area of two dimensional polygons and circles. Students find the surface area and volume of prisms and pyramids.
Pupils explore the concept of dimension and its affect on overall volume. They construct rectangular prisms out of paper, then fill their prisms with popcorn. By transferring the same amount of popcorn to various prisms, they are able to compare the different sizes. This makes the concept of volume not only visual for your class, but also quite tasty!
In this Pi worksheet, students answer 20 questions about diameter, circumference, and the value for Pi. Students use GeoGebra to investigate the Pi relationship.
A Classical & Relativistic Trip to a Black Hole
Students calculate distance, velocity, acceleration and time on their fantasy trip to the black hold. They apply Newton's Laws of Motion and calculate circular motion. They discuss any questions that may arise.
How Much Does It Really Weigh - Enrichment 7.7
In this multiplying decimals worksheet, students research the weight of 10 common objects on Earth, then multiply by a decimal factor to find the weight of each object on the different planets. Students research how scientists calculate the mass and radius of planets, then write a paragraph describing the methods.
Towers of Steel
This lesson starts with geometers discussing how to find the volume of a cone and pyramid, using what they know about the volume of a cylinder or prism. Then, using the formulas, they calculate the volume of cones and other conics using the correct formula.
Round and Round enrichment 16.6
In this recognizing round and round worksheet, 6th graders use the diameter or radius of circular objects and distance traveled to find the circumferences and revolutions and use this information to solve word problems. Students solve six word problems.
The difference between circumference and radius is the focus of this geometry instructional activity. After entering data into a spreadsheet which has the formula for circumference of a circle built into it, pairs of learners perform a hands-on exercise where they cut pieces of string that go around the lids of jars, then lay the string across the lid to see the relative size difference between circumference and radius. A good instructional activity with many components.
Mini-Video on Ion Size
Sal discusses what happens to elements when they become ionized. He demonstrates that when neutral atoms become ionized, it can significantly change their relative atomic sizes. He uses the Periodic Table of the Elements to illustrate this important point.
The Milky Way: A Mere Cloud in the Cosmos
In this galaxy worksheet, students calculate the volume of the Milky Way Galaxy, they determine the total mass, the density and the volume of the Milky Way Galaxy. They also solve 2 problems about the volume and size of the universe in comparison to the Milky Way Galaxy.
Direct, Inverse, And Joint Variation
Students engage in a lesson that has them practice solving equations using multiplication and division. They practice solving problems using the properties needed and then students practice changing word problems into an equation.
Chemists compare the electronegativity, ionization energy, electron affinity, and ionic radius of different elements. This worksheet is composed of 11 multiple choice questions, and 8 written explanations. Critical thinking skills are required, making this a terrific homework assignment. An answer sheet follows for your convenience.
