1.4  Plants need water



                Activity


                Healthy plants?

                What could we do to help these plants grow?

                What do you think will happen to these plants?

                Tell other people what you predict.



                                                                          B
                            A









                           If plants do not have                      If plants have too much

                      enough water, they can die.                        water, they can die.




                 Think like a scientist 1                      Do plants get water

                                                              through their leaves
                 How plants get water
                                                                or roots? Let’s do

                   You will need:                                      a test!

                   two plants, a plastic bag, string, a watering can



                 Zara pours water onto the leaves of one plant.

                 She puts a plastic bag around the leaves of the


                 other plant and waters the roots.

                 Predict what will happen.

                 Now try this science investigation.


                 Observe what happens.

                 Draw the plants before and after the investigation.

                 Make sure you wash your hands after touching the plants.
