# Nasa Wavelength

## Simple Machines

Learners will gain an understanding of simple machines and how they may be used in our everyday lives. Students will also have an opportunity to design a Rube Goldberg Machine of their own. This is lesson 10 of 16 in the MarsBots robotics learning module.

## MY NASA DATA: Basic Line Plots

In this data analysis activity, students interpret basic line plots of wind speed using authentic NASA data. The lesson provides detailed procedures, related links and sample graphs, follow-up questions, extensions, and teacher notes.

## Open Clusters versus Globular Clusters

In this activity, students will describe similarities and differences between galactic star clusters and globular clusters.

## Compass Needles around a Simple Circuit

This is an activity about electromagnetism. Learners will set up a simple circuit using a battery, wire, and knife switch, and then use a compass to map the magnetic field lines surrounding the wire. Next, they will add a coil of wire to the simple circuit and map the magnetic fields again.

## Planetary Nebula NGC 2440 Lithograph

The lithograph contains a Hubble Space Telescope image that shows the colorful Planetary Nebula NGC 2440 with one of the hottest known white dwarf stars at its center. The text briefly explains the process of stellar death of sun-like stars and those with a mass greater than eight times the Sun.

## Two Versions of Gravity: Newton and Einstein

The goal of this lesson is for two groups of students to exchange information (e.g., through poster presentations, Podcasts, debates, or PowerPoint presentations) about how two different theories explain a natural phenomenon: Newton's Law of Gravitation and Einstein's General Theory of

## Dr. Smith vs. the Lawyer

This math problem demonstrates a lawyer's use of some very simple science and math. The case involves a \$26 million lawsuit over a construction waste landfill and lead contamination.

## SciJinks: Play Satellite Insight

In this game students have to think and move fast to keep up with the challenge of capturing and storing the massive flow of different kinds of data being captured by a GOES-R weather satellite.

## How Does Remote Sensing Search for the Geographies of the Past?

Remote sensing offers three perspectives on human or physical features: aerial (birds-eye), oblique (angled) and ground-level. Sketching a classroom object from each of the three perspectives provides students with the foundation to then complete several activities.

## MY NASA DATA: Identifying Ozone Variations over Different Locations

Satellite data on ozone trends is investigated for different locations: the high Southern latitudes, the student's hometown, and a city near the North Pole. Students will download and plot ozone data for each location spanning a one year time period.
