This is a teacher demonstration used to show an example of kinetic molecular energy using food coloring and water. The students are also given opportunity to develop their own questions and tests.

This activity provides for small group investigation of the properties of different liquids leading to the discovery that liquids are different in many ways, including density.Students would be led to a very beginning understanding of density.

This activity is an extension of the FOSS Variables Lifeboat investigation. Students choose a lifeboats variable to investigate, write up an experiment based on the variable to be tested, test the variable, and create a lifeboats investigation poster to share their results.

You can space weights along a string so that they make a regular rhythm of beats when they strike the ground.
Through this activity several concepts can be explored: acceleration, gravity, weight, rhythm, sound.

The 9-session NASA Family Science Night program invites middle school children and their families to discover the wide variety of science, technology, engineering, and mathematics being performed at NASA and in everyday life. Family Science Night programs explore various themes on the Sun, the Moon, the Stars, and the Universe through fun, hands-on activities, including at-home experiments. Information about Family Science Night implementation and support resources, including the facilitator's guide, are available by registering on the Family Science Night Facilitators website (see Related & Supplemental Resources for link).

This lesson is a presentation of famous scientist throughout history where the students will learn and take notes about the contributions and discoveries made in science.

This is an activity about using what you can see to identify what you cannot see. Learners will examine images of the Sun taken over one complete solar rotation and look for data features that appear on the farside of the Sun which persist at the same location as the Sun rotates to bring that part to the side facing Earth. This activity requires access to the internet to obtain images from the Stanford University solar magnetic map archive from 1996 to 2011. This is Activity 6 of the Space Weather Forecast curriculum.

Play with a bar magnet and coils to learn about Faraday's law. Move a bar magnet near one or two coils to make a light bulb glow. View the magnetic field lines. A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude of the current. You can also play with electromagnets, generators and transformers!

Light a light bulb by waving a magnet. This demonstration of Faraday's Law shows you how to reduce your power bill at the expense of your grocery bill.

All of us have felt sick at some point in our lives. Many times, we find ourselves asking, "What is the quickest way that I can start to feel better?" During this two-lesson unit, students study that question and determine which form of medicine delivery (pill, liquid, injection/shot) offers the fastest relief. This challenge question serves as a real-world context for learning all about flow rates. Students study how long various prescription methods take to introduce chemicals into our blood streams, as well as use flow rate to determine how increasing a person's heart rate can theoretically make medicines work more quickly. Students are introduced to engineering devices that simulate what occurs during the distribution of antibiotic cells in the body.

Working individually or in groups, students explore the concept of stress (compression) through physical experience and math. They discover why it hurts more to poke themselves with mechanical pencil lead than with an eraser. Then they prove why this is so by using the basic equation for stress and applying the concepts to real engineering problems.

This is a hands-on inquiry activity using zip-lock plastic bags that allows students to observe the process of fermentation and the challenge of producing ethanol from cellulosic sources. Students are asked to predict outcomes and check their observations with their predictions. Teachers can easily adapt to materials and specific classroom issues.

In this primary grades Illuminations lesson, students identify figures on a football field. They look for both congruent and similar figures, and they consider figures that are the same but that occur in a different orientation because of translation, rotation, or reflection. The lesson includes a student worksheet and discussion questions.

This is an activity about cause and effect. Learners will investigate various online sources to find data and other pertinent information regarding reported effects on Earth for the solar events they identified in the previous activities in this curriculum set. Then, they will summarize their findings for this activity as part of the overall Space Weather project. This is Activity 13 of the Space Weather Forecast curriculum.

This is an activity about searching online data archives for solar wind events. Learners will find at least three episodes of increased solar wind activity impacting Earth using direct measurements of solar wind velocity and density. Then, they will characterize each events by its rise time, the time it takes for the solar wind speed to rise from normal levels to the peak speed of the event, and the percentage increase in solar wind velocity. This is Activity 11 of the Space Weather Forecast curriculum.

In this video segment from Cyberchase, Harry decides to train as a firefighter and uses line graphs to chart his physical fitness progress.

This activity is an investigative introduction to class 1 levers. Students create levers and record observations to determine the use and components of a lever.

This is an exploratory activity where students in small groups discover the relationship between the force of resistance, the force of effort, and placement of the fulcrum in a first class lever.

This activity is an observation lab where students observe the colors emitted by various metal ions in salt solutions.
