This activity is a teacher-directed investigation where students observe leeches, create questions and determine which ones are investigable. Together, teacher and students design and carry out a test for their question and record the information in a science notebook.

This lesson is an introduction to a unit on habitat. It is designed to combine literature and science.

The goal of this task is to use geometry study the structure of beehives. Beehives have a tremendous simplicity as they are constructed entirely of small, equally sized walls. In order to as useful as possible for the hive, the goal should be to create the largest possible volume using the least amount of materials. In other words, the ratio of the volume of each cell to its surface area needs to be maximized. This then reduces to maximizing the ratio of the surface area of the cell shape to its perimeter.

Just about everything you can do on a computer—checking your email, posting to Facebook, online banking and shopping—is powered by software. The people who come up with that software, and keep it working efficiently, are behind the scenes of a big portion of our lives.  Software engineering is an exciting career,.In this remix, some reflections questions for students have been added.

Student teams follow the steps of the engineering design process to meet the challenge of getting their entire class from one location on the playground to the sidewalk without touching the ground between. The class develops a well thought-out plan while following the steps of the engineering design process. Then, they test their solution by going outside and trying it out. Through the post-activity assessment, they compare their problem-solving experience to real life engineering challenges, such as creating new forms of transportation or new product invention.

This is a guided inquiry in which the students determine how a light bulb works.

This article highlights the four recommended research-based practices described in the How to Organize Your Teaching U.S. Dept. of Education What Works web site.

This activity is a student based inquiry looking at various natural disasters and their impact.

This activity allows students to deduce part of Newton's Law of Inertia that states an object in motion will stay in a straight line motion unless an outside force acts on it.

Students will create and investigate testable questions about how basil changes based on growing conditions.

During this activity, students will investigate leech behavior. Students will learn to ask a question about leech behavior that can be investigated.

In this hands-on inquiry activity, students will design and construct an apparatus that will permit an egg to survive a nine foot fall. Students are given limited materials, so they must critically think about the design and improvise strategies during the building of the apparatus

This activity is an introductory activity where students observe the characteristics of ionic compounds and crystals They also work on making observations and writing hypotheses.

This activity is an extension to standard labs that have students generate a pH curve from strong acid/strong base data. Students are asked to predict and test how the the titration end point will shift when titrating vinegar (a weak acid) with NaOH (a strong base).

This learning experience is where students launch a bottle rocket and compare how long the bottle was in the air to how much water is placed in the rocket.

This is an exploratory activity involving matter and density. There are many assessment pieces including a laboratory.

This activity is a field collection investigation where students gather earth materials and make observations about their collection that leads them to discuss the nature of Earth surface and how it is changing.

This activity is an investigation where students gather information about the rate of evaporation, interpret their findings, and apply this knowledge to the water cycle.
