Source document note

The official curriculum document has a fault in this entry, so the curriculum text above is transcribed exactly as printed:

• indicator text - p.54: this is the only indicator under content standard B3.2.2.1 and it is numbered .2; the document prints no B3.2.2.1.1. The code itself is printed "B3.2. 2.1.2", with a stray space

Exemplars (from the NaCCA curriculum)

- Begin this activity by asking learners to predict whether it is possible for bean and maize seeds to germinate/sprout in water without soil.
- Place learners into groups and give each group two transparent glasses or plastic containers (labeled A and B), cotton wool, water and viable maize and bean seeds.
- Learners pack container A with the cotton wool and push one of each of the different seeds through the side of the container but not to touch the bottom.
- Guide learners to pour a little water to soak the cotton wool. The set-up is left to stand for one week while keeping the cotton wool always wet.
- Guide learners to prepare container B using the same method but with a dry cotton wool.
- Learners observe the set-up critically and record whatever they see.
- Challenge learners with the question: What made the seeds germinate in set-up A?
