Engage your students with this interactive and informative lab. Designed for elementary students, this lab explores the topic of how our bodies use energy to move. Perfect for science lessons, this resource will help students understand the connection between energy and physical activity. It is written at the 3rd-grade reading level.

In this activity, students will first begin by exploring the area and perimeter.  Tell your students to make a shape that has a specific area or perimeter and then give them time to explore and create.  As you go, make the math challenges more difficult.  When they have had a chance to explore, have them play the game.  The challenge is to see how many levels they can complete.  Keep in mind that the last level is unique in that students now have to create a shape with a specific area while creating a fraction of the shaded color like the second image below.

In this lab, students will design and experiment to determine which sediment type is the most permeable and porous. This is very open to a student's design. The teacher should give little to no help with this experiment. I use this lab to assess a group's ability to design and experiment and come up with a statement of conclusion. I am looking for their ability to use time wisely, set up an experiment, gather data, practice safe lab techniques, and use variables correctly. Teacher reflection and procedures are included.

This Study Jam video does a great job demonstrating the differences between weather and climate.  It discusses how temperature and air pressure can change due to a change in elevation.

This video can also be used during reading units dealing with compare and contrast.

This "It's OK to be Smart" video discusses the human nose and its awesome ability to sense smells.  Please note that this video does talk about human sperm so you need to judge your students' maturity level.  Nerves, olfactory receptors, eyes, and ears are also discussed in the video.

Students solve these array problems by counting the images down and across and then multiplying the numbers.
