Plants In Action Update

Two weeks ago the students in 4KJ formed inquiry groups for our new topic, Plants in Action. To begin our investigations, we planted seeds in a snaplock bag. You can read about it here.

There were no noticeable changes after the first couple of days of observation. However, when we returned from our Maldon camp last week, we saw that our seeds had started growing!

The photos below show the growth of our broad beans and long beans.

TUESDAY 6TH AUGUST 2013

My plants are making a big changes right now.

Here are the changes I have noticed since last week.

CHANGES:

  1. From one of our broad beans there is a really big root which is about 6cm long.
  2. From the same broad bean, a big shoot is growing  from the root on the side of the seed. It is about 3cm long.
  3. The long beans aren’t changing that much, but some of them are growing really long roots.
  4. One of the broad beans has been very smart and hidden under the cotton wool.

What changes have you observed in your seeds?

Have you ever grown seeds or plants at home? If so, what kind?

Do you know the parts of a plant? What do these parts do?

Plants in Action

Today we launched our new inquiry topic, “Plants in Action”.

During this unit of work, students will learn about:

  • Plants and plant growth
  • The changes that occur in a germinating seed
  • How pollination occurs
  • How fruit develops.

During the term, students will increase their vocabulary and make observations about plant growth and seed germination in their individual science journals.

To begin our topic, students formed inquiry teams in class today. Each team member has a special role within their group. These roles are:

  • Manager – Collects and returns all materials the team needs.
  • Speaker – Reports back to the class during discussions.
  • Director – Makes sure that the team understands and completes each step.
  • Recorder – Records any notes and observations that will assist the team to complete their science journal.

Our focus today was bean seed germination.

Students planted broad beans and some long beans in snaplock bags. Over the coming weeks, students will observe the seeds and record any changes in their science journals.

Once the seeds were planted, students wrote a procedural text to explain the process in their science journals. You can read Millie‘s procedural text below with the photos.

HOW TO PLANT SEEDS IN A SNAPLOCK BAG

Equipment: snaplock bag, cotton wool, broad beans, long beans and water.

1. Grab a handful of cotton wool (enough so that your bag is half full) and put in in your bag. You may have to squish it down a bit.

2. Carefully wet the cotton wool. It cannot be drenched, so do not turn the tap on very hard. Turn it on so there is just a little trickle and the  cotton wool is just damp.

3. Take 2 – 3 broad beans and 5 long beans (you may choose to do a bit more or a bit less depending on the size of your bag) and push them gently into the cotton wool.

4. Hang your bag up on a window, where it will get sunlight. You need to leave the top of your bag open, so the beans will have air.

5. The beans don’t grow instantly, you may have to wait for a couple of weeks. You may need to water your beans during this time.
