Students will make and record observations as well as identify experimental variables. Students will conduct several investigations to help them to understand the differences between chemical and physical changes. Students will record investigative observations and use their observations to provide evidence that a physical or a chemical change has occurred. |
| Drink Mix Mix-Up | In this inquiry activity, students will identify unknown powdered drink mixes. They will use their knowledge of various physical properties to design tests for the unknown drink mixes and then compare them to the known. Students will use their own generated data as evidence to form a conclusion and support their findings. |
| Knight Shipping, Inc. | In this design challenge students will take what they have learned about calculating the volumes and densities of cones, cylinders, and spheres, to decide which shape would make the best shipping container. Students will calculate the volumes and densities to help select the best design and then test them to move at least 3 containers of the chosen shape across the classroom. Students will fill the shapes with marshmallows to visually confirm which shape would hold more. |
| Maintaining Mass | The student will demonstrate that mass is conserved when substances undergo chemical and/or physical changes through experimentation and evaluation of experimentation procedures. Students will be able to analyze the demonstration and provide evidence for or against the law of conservation of mass.Students will first view and then hypothesize, based on their knowledge of the law of conservation of mass, why a teacher demonstration does not seem to prove the law. Students will then explore a modified version of the experiment to determine ways that the teacher demonstration should have been changed to show conservation of mass effectively. |
| Measurement and Data Collection | In this interdisciplinary lesson, students will practice the skill of data collection with a variety of tools and by statistically analyzing the class data sets will begin to understand that error is inherent in all data.

| Overloading Circuits | In this design challenge, students will explore electrical circuits. Students will use their skills in science, math, and technology to determine how many light bulbs can be powered off of one circuit. Students will build circuits, measure luminosity, graph data, analyze the data and then report their findings to Kiser construction. |
| Shipwrecked Pirates | In this lesson, students will take the role of shipwrecked pirates. Working in groups, they will have to use the concepts of force, speed, scatter plots, and literal equations to come up with a way of getting one student to a nearby sister island so that they will both have enough food to survive. |
| Expanding the Universe | Students will draw three dots on an unblown balloon to represent three different galaxies. They will measure the distance between these "galaxies" and then blow up the balloon in three stages, measuring the distance between the "galaxies" at each stage. |
| Rocks Makin' Rocks: Rock Cycle Simulation | Students will participate in a simulation model of the rock cycle. Collecting data by throwing die, students will develop an understanding of the movement of atoms and rock particles through the rock cycle. |
| STEM Catapult Challenge | In this lesson, students will design catapults for offense that will be able to shoot down as many objects as possible in a 20-object tower. They will also design a 20-object tower for defense that is least likely to be knocked down by their opponents catapults. As they complete their investigation, they will be designing and implementing two experiments in one. They will identify a problem, make a prediction, collect and analyze data, and draw conclusions. By the end of the lesson, they should be able to differentiate repetition from replication as well. |
| What if ….you never saw another shell? | This lesson connects the Carbon Cycle with the elevation of global temperatures causing dissolution of carbon-containing substances and rise in acidity. Students conduct a simulation experiment and model carbon loss due to temperature changes lowering pH. |
| Starry Science | In this engaging lesson, students will investigate and explore the effects of temperature, size, and magnitude on the luminosity and life span of stars using glow sticks. This lesson includes a guided inquiry lab and website exploration. |
| Choosing the Best Magnet Program for a High School | In this Model-Eliciting Activity (MEA), students will try to decide which magnet program they would choose for a high school.
Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought processes. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.

| Discovering Kepler's Law for the Periods of Planets | Students listen to a video that describes Kepler's determination that planetary orbits are elliptical and then will use data for the solar distance and periods of several of the planets in the solar system, then investigate several hypotheses to determine which is supported by the data. |
| NASA Beginning Engineering, Science and Technology | The NASA BEST Activities Guides is designed to teach students the Engineering Design
Process. These lessons are created to accommodate grades 6-8.
All follow the same set of activities and teach students about humans' endeavor to return to the
Moon. Specifically, how we investigate the Moon remotely, the modes of transportation to and on
the Moon, and how humans will live and work on the Moon. |
| Scientific calculations from a distant planet | Students will act as mathematicians and scientists as they use models, observations and space science concepts to perform calculations and draw inferences regarding a fictional solar system with three planets in circular orbits around a sun. Among the calculations are estimates of the size of the home planet (using a method more than 2000 years old) and the relative distances of the planets from their sun. |
| Measurement in the Science Classroom | Students will practice measuring length, mass, volume in a variety of ways using a variety of tools including triple beam balances and graduated cylinders. Density will then be calculated. |
| Force (Weight versus Mass): Newton's 2nd Law | Students will examine the relationships between mass, force and acceleration, applying Newton's 2nd Law.
This is part 2 of a two-part lab. It is recommended that the teacher cover the first lesson (, ID 51003) prior to completing this lesson. |
| Dissolving Gobstoppers Using Controls and Variables | Students will conduct a simple laboratory experience that practices the proper use of controls and variables. Students will conduct a controlled experiment in their laboratory groups. |
| Ancient Archery: Scientific Method and Engineering | In this Model Eliciting Activity (MEA), students must assist an archaeological research team to determine which material ancient archers likely used to string their bows. Students must design an experiment to test various materials for power, precision, and durability. After the data is collected, they must develop a system to determine which material would have been most desirable for the ancient archers.
This MEA is a multifaceted lesson designed to address both the processes of discovery through scientific investigation and problem-solving through engineering. The full-scale MEA involves the development of a complete experiment and a proper lab report and then an application of the collected data to address the problem-solving requirement of the MEA.

| Elements of Experimental Design | Understanding the process of experimental design. It is a process that is structured in order to control variables, maintain consistency, incorporates a hypothesis or a prediction and is testable. The design of the experiment specifies that the experiment must be repeated 3-5 times in order to validate your findings. |
