1 - Getting Started ~4 mins
Look at the plants you set up earlier in this project. Which ones look healthy and which ones look weak or unwell? What do you notice before we measure anything?
2 - Remember Our Question ~4 mins
Today's focus word is evidence: what we saw or measured that helps us answer our question.
What did we ask earlier in this project, and what did you predict would happen?
3 - Observe and Compare ~10 mins
With your group, look carefully at both plant cups: the one that grew in one condition (for example on the windowsill) and the one that grew in the other condition (for example in the dark press). Use a ruler to measure how tall each plant is in centimetres. Write both heights on your watching log straight away so you do not forget them. Notice colour, leaves and stems as well as height. Talk about what is the same and what is different.
4 - Pool Our Heights ~8 mins
Each group will call out both conditions and how many centimetres tall each plant is. We will put the heights on the board together.
Then we will look at the chart. Which bars are tallest or shortest?
Which plants grew better, and how can we tell from the bars and from looking? Remember: we also use colour and how full the plant looks, not only which bar is tallest.
How tall did our plants grow?
5 - Record What We Found ~8 mins
On your Investigation Journal page, do two jobs. First, draw or label the two plants, write how tall each one is, and note one other difference such as colour or leaves. Then write one short sentence about what plants seem to need to grow well, using what you noticed.
