Healthy hearts!

Science Year 2
This unit is part of Year 2 Science Healthy Animals

Objectives

Feel your heart pumping before and after running in the playground and discover that exercise makes your heart pump harder and faster! Carousel around different physical activities, observe the effects and answer questions in pairs.

Science Objectives
i) Describe the importance for humans of exercise, eating the right amounts of different types of food, and hygiene.

Working Scientifically

  1. Observe closely, using simple equipment.
  2. Perform simple tests.
  3. Use their observations and ideas to suggest answers to questions.
  4. Gather and record data to help answer questions.

Lesson Planning

Teaching

  • Understand that exercise makes the heart work harder and is an essential part of a healthy lifestyle
  • Explore the idea of warming up muscles through a simple investigation
  • Warm up and then carousel around different physical activities, counting rate of heartbeat
  • Observe and record the effects of exercise (warm skin, thirsty, heart rate increased, breathing heavily).
  • Consider questions such as: why is exercise important for keeping healthy? What kinds of exercise do you enjoy doing? What exercise can you do outside school?

Activities

  1. Understand that exercise makes the heart work and that warming up before exercise is important
  2. Know that some exercise makes their heart beat fast and some slows it down
  3. Begin to understand that they can observe changes and record data in a simple table

Investigation
Explore the idea of warming up muscles by investigating what happens when cold elastic bands are stretched without being warmed up.

Warm up and then carousel around different physical activities, counting rate of heartbeat. (Exploring, Observing over time)

Vocabulary
Heart, beating, healthy, exercise
