Jumping to the decade

Write simple RCQ for kid beginners: Broken Arm Blues Kyle and Carrie did everything together. They worked on their homework together, played soccer together, and went to karate class together. "You're like two peas in a pod," their father liked to say. One day, while playing soccer, Kyle broke his arm. A doctor at the hospital put Kyle's arm in an arm cast. Three days later, Carrie broke her arm in karate! The same doctor put Carrie's arm in a cast, too. "Cool. We get to have broken arms together," Kyle said. "Let's get everyone to sign our casts," said Carrie. The first week they had their casts was exciting. Kyle and Carrie didn't have to run laps in soccer practice. Their parents wrote their homework for them. Everyone signed their casts, even their teachers. The second week they had their casts, Kyle and Carrie both had the broken arm blues. So many things were hard to do with one arm in a bulky cast. Carrie couldn't put her hair in a ponytail using just one hand. Kyle couldn't play video games, and neither of them could jump rope. "We can't do anything fun!" yelled Carrie. "I'm so bored," Kyle said. "I feel so blue," Carrie agreed. Kyle and Carrie had to watch their soccer team play without them. They couldn't even clap their hands when their team scored a goal. The third week Kyle and Carrie had their casts, they were angry. One of their best friends had a birthday party with a jumping castle at the pool. They couldn't jump or swim. They had to watch everyone else having fun. "I'm sick of having a broken arm!" yelled Carrie. "My arm is so itchy!" Kyle howled. "Mine, too," Carrie said. "And your cast is starting to smell." "Your cast stinks," Kyle said, holding his nose. The fourth week Kyle and Carrie had their casts, they decided to team up to beat their blues. Together, they could jump rope. They each used one of their hands to clap together when their team scored in soccer. "You're like two peas in a pod," their father said. After six weeks, their casts were off! Now they could swim, play soccer, and go to karate class. Now no one had the broken arm blues!

Make a quiz about the following mini-lab: Mini-Lab: Measuring Reaction Time and Hang Time Objective: In this mini-lab, you will work in groups to measure distances and use calculations to determine your reaction time and hang time. These experiments will help you understand fundamental concepts in physics and reaction time. Materials: Ruler (with metric units) Sticky notes or masking tape A vertical surface (like a wall) Clear space for jumping Calculator (if necessary) Part 1: Measuring Reaction Time Introduction: Reaction time is the time it takes for a person to respond to a stimulus. In this experiment, you will measure distances and use them to calculate your reaction time. Procedure: Preparation: Attach a sticky note or masking tape to the bottom edge of the ruler. Stand facing your partner. Hold the ruler vertically with the zero end at the bottom, lined up with your index finger and thumb. Measurement: Your partner will release the ruler without warning. When you see the ruler fall, try to catch it as quickly as you can. After catching the ruler, measure and record the distance the ruler fell. Data Collection: Each group should repeat the ruler drop experiment three times. Calculate the average distance and record it. Part 2: Calculating Hang Time Introduction: Hang time is the total time a person spends in the air while jumping. In this part of the mini-lab, you will measure distances using tape to mark your jump height and use them to calculate your hang time. Procedure: Preparation: Stand in front of a wall. Reach up as high as you can with your feet flat on the floor. Use a piece of tape to mark this point on the wall. Your partner should stand ready to observe and assist. Measurement: With a loop of tape on your finger, jump as high as you can. Stick the tape on the wall where your fingertips reach when jumping. The difference between the two pieces of tape marks your jumping height. Data Collection: Each group should repeat the jump and measurement three times. Calculations (Make sure to check your units before doing any calculations): Calculating Reaction Time: Use the average distance from Part 1. Calculate the time it took for the ruler to fall using the formula: y = viy t + ½ g t², where viy in this case is zero and "g" is the acceleration due to gravity (approximately 9.81 m/s²). This time is your reaction time. Calculating Hang Time: Use the average jump height difference from Part 2. Calculate the time you spent in the air using the formula: y = viy t + ½ g t². Remember that the velocity at the peak is zero and the total time in the air is twice the time it takes to get to the peak. Conclusion: Discuss your results with your partner and other groups. Compare your reaction times and hang times. Think about factors that may have influenced your results and how you can improve your reaction time and jump height. Consider the real-world applications of understanding reaction time and hang time in physics and sports. Assessment: Work with your partner to write a short report summarizing your findings, including calculations of your reaction time and hang time. Reflect on the factors that may have affected your results and propose improvements to your techniques. Be prepared to discuss your findings in class.

Bonk, the Healthy Monster A candy store has just opened. Bonk has been waiting. He runs inside with money from his piggy bank. "Wow!" he says. "There's cotton candy!" Bonk says. He sees chocolate eggs and rainbow taffy, too. Bonk buys and eats the candy. The next day, Bonk goes to the candy store. "There's root beer!" Bonk says. He sees bubble gum and jelly beans, too. Bonk drinks the soda and blows big bubbles. Day after day, Bonk eats junk food. His piggy bank gets lighter and lighter. But Bonk does not. The candy store owner gives Bonk a balloon. "You are my number one customer," says the owner. Later, Bonk visits the dentist. The dentist looks at Bonk's teeth. "Candy and soda are not healthy for you or your teeth," he says. The weeks pass by with more trips to the candy store. Soon, Bonk can't ride his bike as fast as he did before. Jumping rope is hard work, too. Sometimes, Bonk's tummy hurts. "What should I do?" Bonk asks Lurk and Uzzle. "I know," says Lurk. "Me, too," says Uzzle. Lurk, Uzzle, and Bonk go for a long walk. "You need exercise to be healthy,' says Lurk. They have a picnic of apples, cheese, and fresh brown bread. "You need good food to be healthy, too," says Uzzle. "But what about rainbow taffy and cotton candy?" Bonk asks. "You can have a piece or two," says Uzzle. "I can't have the whole bag?" asks Bonk. "No, never have the whole bag," says Lurk. Bonk's tummy begins to feel better. Soon, he can race his bike and jump rope again. Now, Bonk is not the number one customer at the candy store. But, Bonk is number one at being healthy!

Where’s the Joey? What's a Joey? A joey is a baby marsupial (mar-SOO-pee-ul). A marsupial is an unusual type of animal. Its babies are carried in a pouch, or pocket, on the mother's belly. As it grows, the little joey stays hidden inside the pouch. Safe inside, the tiny joey drinks milk and grows while it is carried around. Even after it can walk, the joey may still ride in mom's pouch. There are over three hundred types of marsupials. Most of them live in Australia (aw-STRAYL-yuh) and eat plants. Let's look at a few kinds of marsupials and their joeys. A Jumping Joey This joey stays in its mother's pouch for eight months while it grows very tall. Its feet and tail grow very long. too. Can you guess what it is? It's a red kangaroo! A red kangaroo is the largest marsupial. It can stand over six feet tall and weigh 200 lbs (91 kg). It can jump 30 feet (9 m) with each leap! A Joey That Lives in a Tree When grown, this little joey will look like a furry teddy bear with big ears. It will live most of its life sitting in trees and eating leaves. Can you guess what it is? It's a koala! A koala lives, eats, and sleeps in eucalyptus (yoo-kuh-LIP-tus) trees. It is happy just to sit anp eat lots of leaves every day. A koala usually only walks around at night. Joey the Screamer This marsupial mom might carry three or four noisy joeys in her pouch at one time. Her little joeys can scream very loudly. What are they? They are Tasmanian devils! The Tasmanian devil gets its name from its loud screams, sharp teeth, bad smell, and wild look. It is a meat-eater, and lives only on the island of Tasmania (taz-MAY-nee-uh). Protecting the Marsupials Most marsupials eat plants, and many, like the koala, live quietly in forests. When those forests are cut down, their homes, food, and safety are lost. Other marsupials have lost their sources of food to herds of grazing cows or growing cities. Marsupials Are Special Animals Most marsupials and their joeys live in only one place on Earth. We need to protect their special habitats and food sources-so we will always know where the joeys are.

Bonk's New Bike Bonk has dreams about the bike he wants. It is red with cool handlebars and spokes. Bonk sees the bike on TV. He sees it in the newspaper, too. He opens his monster bank. He has only five pennies. "I have to earn enough money for my new bike," says Bonk. "I will start a dog walking business," he says. He goes door to door asking people if he can walk their dogs. "Can we help walk dogs, too?" asks Jupe. "I'll do it by myself," Bonk says. "I'm saving my money for a new bike." Soon, Bonk's phone begins to ring. People knock on his door. They all want Bonk to walk their dogs! "This will be a fun and easy way to earn money," Bonk says. On Saturday, Bonk picks up each dog. There are big dogs, little dogs. fancy dogs, and plain dogs. The dogs are barking, jumping, and running around. Bonk gets all their leashes together and begins to walk. One dog tangles up his leash. Another dog rolls in the mud. Another dog chases a cat! "This is not fun!" Bonk says. "It is not easy either!" Lurk, Uzzle, and Jupe ride their scooters past Bonk. "Do you want some help now. Bonk?" Jupe asks. Bonk gives each of the monsters a dog to walk. When they are finished walking. the dog owners pay the monsters. "I'm sorry I said you couldn't help with the dog walking," says Bonk. "I couldn't have done it without you." Jupe, Lurk, and Uzzle talk. They give their money to Bonk. "This is for your new bike," says Jupe. "But you earned this money, too," says Bonk. "We want something other than money," says Lurk. "Anything you want," Bonk says. "When you get your new bike, we want to take turns riding it!" says Jupe. "It's a deal!" says Bonk.
