Seventh graders discover the definition of density through a demonstration using ethanol and ice cubes and a class discussion using a SMART Board to illustrate formulas and calculations. Students finish the instructional activity by...

Students find the area and perimeter of rectangular figures. They use this information to find patterns and discover relationships between area and perimeter. Students apply and explain formulas relating to perimeter, area, and volume.

Line drawings of a circle, a cylinder, and a cone at the top of the page contain the formulae for area and volume of each shape. Learners complete the missing information in a chart that lists diameter, radius, height, and area and...

Students, in groups, connect a 10 ohm resistor across their 1.5 volt battery, and take voltage readings every 5 minutes.

Students compare, classify and calculate the area of geometric figures such as rectangles, squares, circles and triangles.

Functions require an input in order to get an output, which explains why the answer always has at least two parts. After only three multi-part questions, the teacher can analyze pupils' strengths and weaknesses when it comes to...

Dig deep into a lesson studying volume. Learners view images of a Guatemalan sinkhole that seems too big to be true! Their task is to determine the amount of material needed to fill the hole using information from news articles and videos.

Challenge young scholars' understanding of thermochemistry with this skills-practice worksheet on Hess's Law. Given a series of five multi-step chemical reactions, students must determine the overall change in entropy...

Create a linear equation for a problem when the intercept information is not given. The two-day lesson introduces the class to the point-slope form, which can be used for problems when the initial conditions are not provided. Pupils...

During this hands-on activity, young chemists build molecular models based on the Lewis dot structure before studying valence shell electron pair repulsion theory. 

Engage young mathematicians in applying their knowledge of area and perimeter with a fun geometry activity. Through a series of problem solving exercises, children use their math knowledge to design different-sized garden...

Thirty at the party won't cost any more than twenty-five. The assessment task provides a scenario for the cost of a party where the initial fee covers a given number of guests. The class determines the cost for specific numbers of guests...

Slopes are not just for skiing. Instructors introduce class members to the concept of slope and teach them how to calculate the slope from a graph or from points. The lesson also includes the discussion of slopes of parallel and...

Next time you need to repave your patio, have your scholars do all the math. They first calculate and answer questions using the area of patio blocks. Next, they determine the cheapest block to use to pave the patio.

Design an efficient cereal box. Scholars use set volume criteria to design a cereal box by applying their knowledge of surface area to determine the cost to create the box. They then determine whether their designs will fit on...

Students investigate the concepts of volume for rectangular prisms and spheres. They measure the volume of one balloon and then consider how many breaths it would take to fill the room with balloons. The rectangular prism being measured...

Employ proportional reasoning and algebraic understanding to a determine a real world math quandary. Intel has created a project based unit to engage learners in using algebra to describe the physical world. They will create equations,...

In this interpolation activity, students use a linear interpolating polynomial and then describe the extrapolated value of the function. This four-page activity contains ten problems.

In this QR algorithm worksheet, students use the QR algorithm to solve an over-determined system of equations. This two-page worksheet contains 11 problems.

Students prepare a balance sheet. In this balance sheet lesson, students learn the parts of a balance sheet and how they are represented. Students use a formula to calculate equity.

Eighth graders discuss and analyze Civil War data, manually graph data on handout, work with partners to enter data into spreadsheets, and create charts on spreadsheet for each data set.

Students enter data regarding the height of classmates into a spreadsheet. Formulas will also be entered to find the median, mean, and mode of the data.

Learners create charts and graphs using a spreadsheet. They chart the number of each gift given day by day from the song, "The Twelve Days of Christmas." They create a bar graph and a circle graph from their data on the spreadsheet.

Students predict the speeds of humans and hermit crabs and investigate their predictions using ratios and formulas. AppleWorks is used for this instructional activity, which includes a data worksheet.
