Grade Six Science

Hello Boys and Girls,

How are you this week? How well are you doing in your tests and quizzes? I know your teachers are giving you many exercises and practice work. These are very good for you.

Last week we found out about the different ways by which seeds are dispersed. Without checking back, see if you can name these ways. We identified eight ways. How many did you remember? We also saw that for a seed to develop into a young plant, there are several conditions that need to be in place. Name them.

Do you remember the stages in germination? Draw a diagram showing how the seed germinates.

I sure you did that well with that.
