# Activities

### Agent Exoplanet

Use the Agent Exoplanet interface to measure changes in the brightness of a star as an orbiting exoplanet transits. Contribute measurements to the Agent Exoplanet community. Describe an exoplanet light curve and its relationship to the physical process causing it.

### Astronaut Training: Dexterity

Working in teams, students must complete a jigsaw puzzle and reveal the hidden word as quickly as possible, while their dexterity is impaired, to simulate the difficulties faced by astronauts when attempting to fix satellites and instruments wearing bulky spacesuits. Assembling a puzzle quickly and correctly will help them understand the importance of dexterity, hand-eye coordination and communication -- essential skills for an astronaut!

### Astronaut Training: Taste

There are no refrigerators or ovens on the International Space Station, but that isn’t the only reason that eating can be a strange experience for astronauts. Due to lack of gravity and shifting fluids, things can taste very different in space. In this activity students will carry out a taste test to explore how our senses affect the flavour of our food, and what this might reveal about eating in space.

### Astronomical Seeing - How Good are the Observing Conditions?

Have you ever wondered why you see the stars in the night sky more clearly on some nights than on others? You are about to measure quantitatively how the Earth’s atmosphere affects the quality of sky images, and thereby imposes fundamental limitations to ground-based astronomical observations.

As a first task, you will acquire two sets of images with a robotic telescope.

As a second task, you will then pick 3 stars in one of the observed fields, and compare how these look on the different images that you have acquired.

### Calculating the Age of Solar System Objects

Author: Sarah Greenstreet and Sarah Eve Roberts

How old are the objects within our Solar System? One method scientists use to answer this important question is counting the number of craters on their surface. This information, combined with the time it takes for craters to form on each body, gives us a strong estimate how old the object is. In this activity students will put this method into practise to calculate the age of five bodies within our Solar System.

### Craters in the classroom

After carrying out this activity, students will understand the effect the mass, velocity and angle of an impacting object has on the resulting crater, in terms of diameter, depth and ejecta rays, and relate this information to the craters on the surfaces of Earth and the Moon.

### Create a Hubble Tuning Fork diagram

In this activity you will create stunning colour images of galaxies and add them to the Tuning Fork template to recreate the famous Hubble image.

### Down2Earth: Making Impact Craters

The aim of this activity is to understand the effect the mass and velocity of an impacting object has on the resulting crater, in terms of diameter, depth and ejecta rays and relate this information to the craters on the surfaces of Earth and the Moon.

### How Big is the Solar System?

How long would it take to travel to the Moon? Could you travel to the edge of the Solar System and beyond? In this activity students learn about the size of the Solar System, beginning with the Earth and Moon and reaching out to encompass the entire Solar System.

### How to Create Stunning Colour Images of the Cosmos (Using GIMP)

This guide will show you how to create beautiful colour images using free software that can be downloaded from the Internet.

### How to Create Stunning Colour Images of the Cosmos (Using Pixlr)

This guide will show you how to create beautiful colour astronomical images, using a free web app called Pixlr.

### How to Find Images Using the LCO Science Archive

There are many thousands of astronomical data files in our archive. We've created an archive search page that lets you limit your search by different attributes. This guide will walk you through the steps to finding the images you want.

### Measure the Age of Ancient Cosmic Explosions

In this project you will calculate the age of a supernova remnant using Las Cumbres Observatory and Hubble Space Telescope observations. You will compare the remnant's radius in images taken several years apart to determine the expansion velocity and use this to calculate how long ago the supernova explosion occurred.

### Measure the diameter of the Sun

In this activity you will measure how fast the Sun moves to caclulate how big the Sun appears in the sky. All you need are some household items and about 20 minutes on a sunny day.

### Measuring the Age of the Universe

The discovery of the expanding Universe was one of the greatest revelations in astronomy. During this activity students will relive Hubble’s monumental discovery by using real supernova spectra to create a famous Hubble Diagram.

### Play Bingo with Charles Messier

Play a game of bingo and learn about the many wonders of the cosmos!

### Plotting a Supernova Light curve

A supernova is the explosive death of a massive star. Although they only burn for a short amount of time, supernovae can tell us a lot about the Universe. Study of supernova has revealed that we live in an expanding Universe and the origins of all of the elements in the Universe that are heavier than iron, they also provide a tool to calculate distances in space. . Using supernova tracker, members of the public contribute to a series of observations of supernova over time. In this activity you will plot the changing brightness of the object and interpret your data to studying how these objects evolve.

### Plotting an Asteroid Light Curve

One of the things we hope to learn through observation of near-Earth objects is their exact rotation rate. We can do by taking a series of observations of the object over time, and plotting the change in brightness. Using Asteroid Tracker you can help collect observations of interesting NEO targets, then plot and interpret your data to measure the rotation period of an asteroid.

### Preparing an Observation Request on LCO

Students will carry out an observing session on the LCO robotic telescope network, using astronomical catalogues and planetarium software to determine target objects suitable for observation with the instruments available, within the allotted time window. Students will select appropriate observation parameters including filters and exposure times.

Students will work in groups to design, test and build a model lander to safely transport their “astronaut” to Earth. This activity will provide your class with an exciting context within which to explore the effects of gravity, air resistance and friction on movement.

### Star in a Box

Have you ever wondered what happens to the different stars in the night sky as they get older? This activity lets you explore the life-cycle of stars.

### Star in a Box (Paper-based)

Have you ever wondered what happens to stars as they get older? This activity lets you explore the lifecycle of stars. In this activity you will explore the evolution of stars with different masses.

### The Cosmic Distance Ladder: Parallax

Determining the position of a star or other object in space is an important concept in astronomy. During this activity you will learn how the distances to nearby stars can be measured using the parallax effect, and put this method into practise to determine the distance to nearby stars.
