First graders make ice cream and determine what makes this liquid turn into a solid.

Fifth graders are introduced to convergence of sequences based on averaging previous terms in the sequence. The power of the "fill-down" function in spreadsheets is exploited. By using various starting numbers, and inferring the limit,...

Students work in pairs, to make a square on the geoboards with a rubber band (or draw one on the dot paper). It can be any size and in any location and share their answers with the class.

Students examine a recent flight of Pathfinder. In groups, they use the information to create a table of values showing the battery charge of the space machine. They predict what the charge would be further on in the mission. They use...

Students make patterns. In this early sequencing lesson, students observe and state a pattern when they see one. The teacher begins be using students to demonstrate a pattern with half of the children standing and every other child sitting.

Students inquire into how the center of mass is the key factor in designing cars. They construct an oddly shaped object and determine its center of mass. They find that engineers are able to predict how objects will behave while they are...

Fourth graders are introduced to the problem using a bottle of medicine. They estimate the volume of the medicine and predict the instructions on the bottle. They then think about how they might solve the problem before asking them to...

Just how far off is the least squares line? Using a graphing calculator, individuals or pairs create residual plots in order to determine how well a best fit line models data. Three examples walk through the calculator procedure of...

Build right angles using coordinate geometry! Pupils explore the concept of slope related to perpendicular lines by examining 90-degree rotations of right triangles. Learners determine the slope of the hypotenuse becomes the opposite...

Using this resource, scholars develop graphs that model situations by showing change over time. They answer 15 questions based on information from charts that show growth in weight. They extend the concepts to an assessment section of...

Seventh graders graph ordered pairs on a coordinate plane. They create a scatterplot. Additionally, they determine the line of best fit and investigate the slope of the line. Multiple resources are provided. An excellent resource!

An outstanding lesson plan on music awaits your young composers! They learn about patterns found in music, the different sections of an orchestra, and see the differences between musicians and a composer. Excellent streamed videos and...

Students explore pi. In this circle measurement lesson, students define and identify radius, diameter, circumference, and perimeter. Students work in groups to measure several plastic lids and record their findings. Students compare the...

Analyze data using technology. Middle schoolers design data investigations, describe data, and draw their own conclusions. Then they select the best type of graph, graph and interpret the data, and look for patterns in trends. They also...

Learners explore the Pythagorean Theorem. For this math lesson, pupils solve problems using the Pythagorean Theorem. They select the appropriate numbers to substitute in the formula to solve problems.

Will human population growth always be exponential, or will we find a limiting factor we can't avoid? Young scientists learn about both exponential and logistic growth models in various animal populations. They use case studies to...

Twelfth graders examine the physics of rocket flight. They build and launch model rockets to measure their performances.

An incredibly thorough, and well-designed lesson teaches youngsters about the presumed extinction and rediscovery of the ivory-billed woodpecker in Arkansas. Learners discuss the environmental factors that led to the birds disappearance....

Sixth graders investigate the relative diameters of planets and distances between them and the cause for seasons on Earth using the 5-E Learning Model. They appreciate the size and distances involved with objects in the real universe....

Not only is pattern recognition an essential skill for young children to develop, it's also a lot of fun to teach! Over the course of this instructional activity, class members participate in shared readings, perform small...

Students explore probability by using games based on probable outcomes of events. They name all of the possible outcomes of an event and express the likelihood of such an event occurring.

Tune in for savings! Scholars investigate pricing schemes for two different online music download sites. After comparing the two, they determine the numbers of songs for which each site would be cheaper.

Don't want to sound corny, but your class will be a-maize-d by an engaging activity! Explore the history of the modern corn plant through a video and Punnett squares. Junior genetics experts get hands-on experience with actual research...

Put the better archer in a box. The performance task has pupils compare the performance of two archers using box-and-whisker plots. The resource includes sample responses that are useful in comparing individuals' work to others.
