What makes a good best-fit line? In the 10th part of a 16-part module, scholars learn how to analyze trend lines to choose the best fit, and to write equations for best-fit lines to make predictions.

Here is a lesson which describes a lab activity in which a rat is dissected, and its heart is studied. The lesson has ample background information about three of the rats internal systems, and excellent lab sheets that support the...

If Earth is modeled by a grapefruit, what planet could be represented by a golf ball? This activity uses everyday and not-so-everyday objects to create a model of the Solar System.

Explore the human body through hands-on activities. Young learners will trace their bodies and place cut out body organs in the proper place, print patterns using cut fruit, sing songs about good nutrition, and use their five senses...

Every moment, the systems in your body are working together to keep you breathing, standing, and thinking. Elementary schoolers explore the human body and its systems with an impressive, 15-page lesson plan that should leave your...

Playing with bugs and buttons has never been so much fun! Offering a variety of different activities, this is a great resource for developing basic skills in preschool and kindergarten-aged children.

This model of the amount of anibiotics in a person's system is represented abstractly by a finite geometric series. Learners translate this real-life situation into algebraic form and then extend their knowlege by answering questions...

Investigating the large numbers of science is the task in a simple but deep activity. Given a one-sentence problem set-up and some basic assumptions, the class sets off on an open-ended investigation that really gives some...

Learners investigate various aspects of the human body  in this imaginative Tree House Detective episode about the biological biosphere. In a series of They take measurements, analyze data, and use technology. The lessons...

The accuracy required by the design and measurement of an Olympic running track will surprise track stars and couch potatoes alike. Given a short introduction, the class then scaffolds into a detailed analysis of the exact nature of the...

In this density of the human body worksheet, students measure several parts of the body to calculate the body volume. Students convert the body volume to body mass and body density.

Third graders find symmetry in their body. In this symmetry lesson, 3rd graders look at different geometric shapes and identify which ones are symmetrical and find their line of symmetry. They measure body parts to the nearest half inch...

Students explore things that are their size, literally. In this early childhood lesson plan, students use their bodies for measuring and comparing sizes as they work in pairs to complete the activity.

Second and third graders explore the size of their bodies. They use string to measure parts of their body in small groups. After measuring with string, students measure the string with a ruler. They then glue their string to a piece of...

Communicating results is just as important as getting results! Learners create a poster to highlight their findings in the experiment conducted in the previous instructional activity in a 30-part series. The resource provides specific...

Integrate art, math, life science, music, and fun in this beginning addition and subtraction activity. Children kinesthetically represent adding and subtracting numbers to 10; they stand up one at a time as you count forward and sit down...

As part of an investigation of transformations of exponential functions, class members use Newton's Law of Cooling as an exponential model to determine temperature based on varying aspects. The resource makes comparisons between...

How are forces and motion important to a swing set? Scholars explore the concepts of force and motion using swing sets. In preparation for their own STEM design project, individuals take surveys and data from peers, complete labs on...

A daily counting routine builds a caterpillar with 100 body segments (marked with symbols to indicate 2s, 5s, and 10s) by the 100th day of school. Provides structured repetition as part of the morning routine so that by 100th day,...

Is foot length to forearm length a linear association? The class collects data of fellow scholars' foot length and the length of their forearms. They plot the data and find a line of best fit. Using that line, they make predictions of...

Learners practice using the Spanish words for the days of the week and numbers. They use a calendar to help them with the activity. They also demonstrate their ability to say "tomorrow will be" and "yesterday was".

Students determine the approximate time a cell spends in each phase of mitosis by counting cells in each phase from a prepared slide. They use a few simple calculations to estimate how long cells spend in each cycle in the body.

Students use geometric shapes to describe body parts. In this geometry lesson, students use geometry vocabulary as they discuss body parts. They practice drawing bodies using shapes based on a wooden model that is poised to show specific...

Investigate division through the use of array models. The lesson focuses on using area models to compare division as sharing with division as grouping. Learners evaluate the usefulness and limitations of the two array models.
