  1. Animals Including Humans Year 5 Working Scientifically: Planning an Investigation

  2. Lesson 2Bones

  3. What will you learn today? Name a variety of animals, including humans, that have a skeleton. Name the functions of the skeleton. I can identify independent and dependent variables.

  4. Key words for today • Bones • Calcium • Control • Dependent variable • Fair Test • Functions • Independent Variable • Joint • Scientific enquiry • Skeleton • Variable

  5. Put a piece of wallpaper on the floor and draw around one of your friends. Draw where you think bones should go. Think about their size and shape. Label any bones you know on your drawing. When everyone is finished, go and see each group’s drawings. You can leave post-it note comments about their skeleton drawing and add any additional information you know about bones! Draw a skeleton

  6. Which are the largest and smallest bones in your body? • Why do bones need to be strong? • What are bones made from? • Find a friend who broke their bone and ask them how they did it. Find out how broken bones are fixed. Some things to think about….

  7. An X-Ray is a picture of bones. They are taken with an X-Ray machine, usually if someone has broken a bone. X-Rays Look at your X-Ray pictures. Which parts of your body do you think your bones protect? See if you can match the organ picture cards with the X-Rays.

  8. Science Lab A (Part 1): What are bones are made of? Science Lab A (Part 2): Planning an investigation Science Lab B: Make a moving skeleton Science Lab C: Animal and human bones Science Lab D: People and bones What are you going to do today?

  9. Lab A (Part 1): What are bones made of? • Wear safety gloves for this investigation. • Look at the bones in the beakers. Beaker A has bones in water. Beaker B has a bones in vinegar. • Take both sets of bones carefully out of the beakers and put them on a paper towel. Make sure you don’t mix them up. • Examine the bones. How are they similar? How are they different? • What has happened to the bones in the vinegar? What conclusion can you make?

  10. Bones are made from calcium. Calcium makes bones strong. Lab A: What are bones made of? Calcium is a chemical element. It’s actually a metal! It can be found in different minerals, such as limestone.

  11. Lab A (Part 2) Planning an Investigation Look at the bones from Lab A again. You are going to plan an investigation to find out the answer to this question: Which bone is the strongest? Plan a fair test to answer this question, including: Your independent variable Which variables you will keep the same Your dependent variable What kind of numerical data you will collect

  12. Lab A (Part 2) Record your learning These are the possible variables in my investigation about the strongest bone: • Independent variables: • Dependent variables:

  13. You are going to make a moving skeleton to show the position of the joints. Lab B: Make a moving skeleton Research the following joints, where they are found and how they work: ball and socket hinge gliding fixed pivot

  14. Now that you know all the different types of joints, you can make your skeleton. Draw your skeleton on the card and cut out the bones. Use the split pins to connect the bones Make a video of your skeleton moving and name all the types of joints Lab B: Make a moving skeleton

  15. You are going to find out about the similarities and differences between the skeletons of different animals, including humans. Lab C: animal and human bones Activity A Look at the skeleton and skull models. Match the bones with the labelling cards. Activity B Use the skeleton cards to compare the skeletons of different animals and humans. Group the animals by the kind of skeleton they have. Choose two different animals. Compare and contrast their skeletons. Create a table to show the similarities and differences between the two skeletons.

  16. Lab D: people and bones Research why people who do these jobs need to know about bones: Archaeologist NASA space scientist Osteopath Radiographer Orthopaedic surgeon Write a short job description of each job (25 words maximum)

  17. Challenge! Challenge 1: Find out about osteoporosis. What is it? Who gets it? How is it treated? How can you avoid getting it? Challenge 2: How could you improve your diet to make sure your bones are healthy? Write a short paragraph and list any foods you think you should eat more of.

  18. What did you learn today? Using what you have learned today, write down 3 questions with their correct answers on post-it notes. Ask your partner your questions, and swap. When you have finished, ask these questions: Did you and your partner answer the questions correctly? How could you improve your answers?

  19. How did you get on?
