This problem uses the same numbers and asks essentially the same mathematical questions as "6.NS Bake Sale," but that task requires students to apply the concepts of factors and common factors in a context.

Through this four part lesson students develop an understanding of the relationship between area and perimeter. The lesson involves students making human rectangles, exploring geoboard connections, playing perimeter war, and playing Square Off from Calculation Nation. The lesson plan includes all data collection worksheets, games pieces, link to Calculation Nation, extension and assessment ideas.

This activity teaches students how to formulate research questions and perform empirical analysis. Students analyse family budgets from late 19th-century industrial workers.

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.

Students use the engineering design process to solve a real-world problem shoe engineering! Working in small teams, they design, build and test a pair of wearable platform or high-heeled shoes, taking into consideration the stress and strain forces that it will encounter from the shoe wearer. They conclude the activity with a "walk-off" to test the shoe designs and discuss the design process.

Students design, build and test shoes to develop new styles and improve existing designs.

This Farming Fast Plants activity introduces a classroom investigation that is easily adaptable for all grade levels and designed to engageteachers and students as investigators. The activity has the practical outcome of producing an abundant supply of Fast Plants seed for future classroom use and for sharing with other teachers. The central question of the activity is ĺŇHow many seeds can your students produce from each seed planted?ĺÓ

Students use wood, wax paper and oil to investigate the importance of lubrication between materials and to understand the concept of friction. Using wax paper and oil placed between pieces of wood, the function of lubricants between materials is illustrated. Students extend their understanding of friction to bones and joints in the skeletal system and become aware of what engineers can do to help reduce friction in the human body as well as in machines.

This four-page handout explains the key steps to follow when caring for Wisconsin Fast Plants (Brassica rapa) throughout their life cycle, from sowing through harvesting seeds. This handout includes information about the materials needed, methods for tending and caring for your plants, and troubleshooting tips.

This PDF chart provides an organizational guide for recording student data as observations, measures(estimates), counts and descriptions on the growth, development, and reproduction of up to 5 Fast Plants (Rapid Cycling Brassica Rapa or "RBR"), and statistical summaries of the data. Data from individual student charts can be aggregated into class or group data charts or a spreadsheet for further display and analysis. These student data can then serve as the basis a deeper understanding of the nature of phenotypic variation, providing a basis for investigating the inheritance of a target characteristic and examples of its variation.

Description and links to computer simulations that allow students to perform genetic crosses quickly. Students can use these simulations to test their genetic models developed from experiments done in the classroom with actual Fast Plants. These simulations were developed in 2000-2001 by Tom Whitaker and were tested successfully by hundreds of students at Madison West High School in Madison, Wisconsin as part of a new approach to genetics used by the Biology I team.

Description: This is an investigation describing the procedure for looking at a seed pod from a mature Fast Plant with a dry pod by sandwiching the pod between layers of clear tape, then exploring the sibling seeds. Questions that might be considered:- In how many ways can you describe the pod (the mother)? Are the pods from one plant more like each other than they are like the pods from other plants? What about the siblings from a single pod? - Do all the seeds in a pod have the same father? - How much variation is there within and between families of Fast Plants? - How much does the environment affect the variation in Fast Plants, e.g. the number of seeds per pod, style length, plant height, days to first flowering, etc? - Is there any relationship between the length of the seed pod and its position on the maternal plant?

Students conduct experiments to determine the flow rate of faucets by timing how long it takes to fill gallon jugs. They do this for three different faucet flow levels (quarter blast, half blast, full blast), averaging three trials for each level. They convert their results from gallons per second (gps) to cubic feet per second (cfs).

In this activity, students are introduced to faults. They will learn about different kinds of faults and understand their relationship to earthquakes. The students will build cardboard models of the three different types of faults as they learn about how earthquakes are formed.

Students have the opportunity to create and interpret data from simple daily questions.

This task provides students the opportunity to make use of units to find the gas need (N-Q.1). The key point is for them to explain their choices. This task provides an opportunity for students to practice MP2, Reason abstractly and quantitatively, and MP3, Construct viable arguments and critique the reasoning of others.

This task allows students to relate addition and subtraction problems to money in a context that introduces the concept of scarcity.

In this primary grades Illuminations lesson, students identify figures on a football field. They look for both congruent and similar figures, and they consider figures that are the same but that occur in a different orientation because of translation, rotation, or reflection. The lesson includes a student worksheet and discussion questions.

Filtering is the process of removing or separating the unwanted part of a mixture. In signal processing, filtering is specifically used to remove or extract part of a signal, and this can be accomplished using an analog circuit or a digital device (such as a computer). In this lesson, students learn the impact filtering can have on different types of signals, the concepts of frequency and spectrum, and the connections these topics have to real-world signals such as musical signals. Students also learn the roles that these concepts play in designing different types of filters. The lesson content prepares students for the associated activity in which they use an online demo and a variety of filters to identify the message in a distress signal heavily corrupted by noise.

Students learn the basic principles of filtering as well as how to apply digital filters to extract part of an audio signal by using an interactive online demo website. They apply this knowledge in order to isolate a voice recording from a heavily noise-contaminated sound wave. After completing the associated lesson, expect students to be able to attempt (and many successfully finish) this activity with minimal help from the instructor.
