Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

Students study the water cycle and how the sun is an important factor.  In this water cycle lesson students investigate how to desalinate water and explore the different densities of fresh versus saltwater.

A thorough math test divides the content into two 40-minutes sections, covering material through algebra and geometry. Problems incorporate analysis and applied problem solving.

The t-test tutorial will fit your needs to a T. After calculating the mean, sum of squares, standard deviation, and variance of two data sets on a spreadsheet, scholars learn to calculate the t-values. They then learn to use the TTEST...

First graders learn the basic needs of plants and identify geometric shapes while planting a fall garden. Combining math and science in one lesson, the resource guides kids through starting their class garden as they...

In this problem solving worksheet, students answer 10 multiple choice SAT practice problems.  Students find the area of circles, slope of a line, solve absolute value inequalities, etc.

In this precalculus test, students select the best answer from 8 multiple choice problems. They solve 4 short answer problems and graph one cycle of each of four equations.

In this trigonometry activity, students look for the answers to the problems to many functions and define the terms found there.

It's not so straightforward — lines can model a variety of applications. Pupils experience linear relationships within the context of science, including Hooke's and Ohm's Laws. Class members got a taste of motion and speed from the...

The price of those new shoes involves more than just money! Individuals explore the concept of opportunity cost using a video clip and gratification discussions. They prepare a budget based off of their set of values in regards to...

As a middle school assessment task, learners interpret the graph of distance versus time for a bike ride. Pupils then determine distance of the trip, length of the trip, and speeds.

Time to see what they've learned. Seventh graders solve a set of seven short problems in the ratios and proportional relationships domain. Applications include photo negatives, washing machines, coffee powder, sleep, stamps, etc.

Responsible farming is important for maintaining natural resources. Eager scientists complete a WebQuest to explore what happens to nitrogen when it enters the soil. They learn about the chemical makeup of nitrogen-based molecules...

Students examine and analyze the characteristic problem of each phase of the business cycle. Students articulate the appropriate choices for each of the problems described. Students apply the writing process to write an essay.

It's probably a good idea to use the unit. Young mathematicians learn about conditional probability using Venn diagrams, tree diagrams, and two-way tables. They also take into consideration independence and the addition rules.

Use STEM activities within the class to provide connections to concepts. The resource includes activities that range from working with buoyancy to building rockets and launching them. Other activities involve the engineering design...

A helpful and versatile activity requires young mathematicians to analyze data in order to create graphs and answer questions. Additionally, it prompts learners to find the mean, median, mode, and range of some of the data sets.

Students conduct an experiment to determine the frequency of pulling various parts of an ancient Greek sculpture out of a hat.

Young scholars relate economics and government policies. In this lesson, students explore the relationship between economics and government policies. They understand how the economy works and can make better decisions as it relates to...
