MIE Unplugged SCIENCE Inquiry Module 1: Scientific observation Session: S6 Observing our environment AIMS This is the final session in the first module: Science observation. In this session we are going to design our own experiment to investigate how light pollution in our local area is impacting either human health and sleep or animal behaviour. By carefully and accurately observing our environment we will see the impact of human activity on our wildlife and our own health. By the end of this session we will have collected all of the observation stickers plus our first methodology sticker! Evaluating Detecting Exploring Observing and making judgments Finding patterns and not missing details Inquiring to learn new things Designing Logic Making rules to test ideas and systems Making predictions and analysing things
MIE Unplugged SCIENCE Inquiry Module 1: Scientific observation Session: S6 Observing our environment Exploring From the last session we looked in more detail at how light pollution impacts on 2 main areas of concern Inquiring to learn new things Disruption to animal behaviours Human sleep and health
MIE Unplugged SCIENCE Inquiry Module 1: Scientific observation Session: S6 Observing our environment Exploring Inquiring to learn new things Sleep is really important for our physical and mental health As a class brainstorm what you think are the benefits of sleep and then write them down on the board Sleep patterns Now lets see how we did!

Helps your body fight illness boosts your immune system 2. Strengthens your heart and cardiovascular system 3. Repairs your body 4. Improves your mood, mental functioning, cognition and productivity 5. Leads to greater exercise performance, more energy, better coordination, faster speed 6. Leads to more social and emotional intelligence 7. Prevents depression and weight gain

MIE Unplugged SCIENCE Inquiry Module 1: Scientific observation Session: S6 Observing our environment How does sleep do all this! Exploring Inquiring to learn new things We have two internal biological mechanisms Circadian rhythms These natural bodily rhythms control the timing of your sleep and cause you to be sleepy at night and wake in the morning without an alarm. Your body s biological clock, which is based on a roughly 24-hour day, controls most circadian rhythms. Circadian rhythms synchronize with environmental cues (light, temperature).
MIE Unplugged SCIENCE Inquiry Module 1: Scientific observation Session: S6 Observing our environment How does sleep do all this! Exploring Inquiring to learn new things We have two internal biological mechanisms Sleep-wake homeostasis keeps track of your need for sleep. The homeostatic sleep drive reminds the body to sleep after a certain time. It tracks how long you are awake. It makes your sleep drive gets stronger every hour you are awake and causes you to sleep longer and more deeply after a period of sleep deprivation.
MIE Unplugged SCIENCE Inquiry Module 1: Scientific observation Session: S6 Observing our environment How does light affect our sleep? Exploring Inquiring to learn new things Perhaps the greatest influence on these two mechanisms is the exposure to light. Specialized cells in the retinas of your eyes process light and tell the brain whether it is day or night and can advance or delay our sleep-wake cycle. Exposure to light can make it difficult to fall asleep and return to sleep when awakened. Can you like of things that you do before bed that make it harder for your brain to produce melatonin and feel sleepy?

MIE Unplugged SCIENCE Inquiry Module 1: Scientific observation Session: S6 Observing our environment Exploring Inquiring to learn new things Bats and bugs are really important to our survival As a class brainstorm why you think bats and bugs are crucial to our survival and then write them down on the board Bat and bug behaviour Now lets see how we did!
MIE Unplugged SCIENCE Inquiry Module 1: Scientific observation Session: S6 Observing our environment Bats are really important for human survival Exploring Bats and bugs are awesome because! Inquiring to learn new things 1. Bats are the biological pest police they can eat their body weight in bugs in a night, controlling the insect population and saving crops and farmers money. Plant dispersal many plants rely on bats and bugs to spread their seeds. Without bats we wouldn t have these fruits or chocolate! Bats aid in restoring forests as they are one of few animals that drop seeds outside of forest areas, bats have been called farmers of the tropics . More than 50% of the old world rainforest is maintained by bats. Plant pollination - Nectar-eating bats are crucial pollinators for over 500 plant species and bugs as well as birds do the rest! Fertilizer production guano is some of the richest fertilizer in the world. Bat saliva may soon be used to treat human cardiac patients. Bat and bug behaviour 2. 3. 4. 5. 6.

MIE Unplugged SCIENCE Inquiry Module 1: Scientific observation Session: S6 Observing our environment Exploring How does light pollution affect bat and bug bahaviour? Inquiring to learn new things Many insect species are attracted to artificial light, which makes them easier for bats to foraging. In fact, areas with bright lights, such as over car yards or tennis courts, can be a good place to watch bats and bugs during warm weather. However, many species of bats are adversely affected by brightly lit areas at night, which cause them to change their migration or feeding routes. This puts them at a much greater risk of death from predation for example by owls or cats, road kill, flying into buildings or sheer exhaustion from being disoriented.

MIE Unplugged SCIENCE Inquiry Module 1: Scientific observation Session: S6 Observing our environment Evaluating Results and Discussion Observing and making judgments Sources of error and improvements! Detecting Finding patterns and not missing details Getting everyone to collect a small amount of data and then putting it all together is a great way to investigate a big problem. Logic Making predictions and analysing things But can you think of any problems with this approach? Did you all follow the same method? Was one method a better approach than others, or should you have collected more variables to define sleep quality, and bat and bug behaviour? Do we need more data to better map our area? Do we need more people living in different environments with different levels of light pollution to tell the true affects of light pollution? What would you do next time?
