Shadow Stick Investigation (Primary Connections Idea):
heks_in_maan.gif
Aim:
1. To investigate what happens to the length and direction of shadows during the day.
2. To determine when shadows are at their longest and shortest.
Method:
1. Form a relatively large ball of plasticine or bluetac.
2. Stick the plasticine or bluetac in the centre of an A3 piece of paper.
3. Stand a stick in the middle of the plasticine or bluetac so that it stands upright.
4. You are going to place your paper with the stick facing upright in the plasticine in the sun and record the shadows that the stick produces throughout the day. How are you going to record your observations? Will you require any further equipment? Record your thoughts in your Science journal and draw and label a diagram of how you will set up your experiment.
5. What do you predict will happen? Will the shadows produced by the stick change or remain constant (the same)? Why do you think this? Do you have any evidence to support your claim? Record your thoughts in your Science journal.
6. Conduct your experiment.
Results: (options)
1. You may like to record your results in the form of a table and then draw a graph to represent your data.
2. You may like to create a graph online using Create a Graph .
3. Alternatively, if you have SMART Notebook software your teacher may like to view the creating a graph video tutorial so you can create graphs using your smartboard.

Cross Curriculum Ideas:
Sundials were used by many cultures to help the people know what time it was. When the Sun was directly overhead and the shadows of people and objects were at their shortest, it was said to be noon. As technology advanced, clocks and watches took the place of sundials.

- Learn how sundials work
- How to build a sundial

For teachers: Summative Assessment of Process skills
Students:
- Carry out an experiment
- Record results and observations
- Make a claim and evidence statement
- Apply knowledge to a new situation
