Y1/2 (A): Lesson 4: Ocean food chains

Display the Presentation: Gimme five! Ask the children to think of five things they remember about plants from their Science lessons this year, tell them to a partner, then give them a high five.

Key facts they remember may include:

• Key plant structures (stem, root, leaf and flower).

• Examples of plants (which could include seaweed as an example of an ocean plant).

• What plants are used for (such as food or medicine).

• The plant life cycle (including the role of seeds or bulbs).

• What plants need to grow (light, water and warmth).

Arrange the class in the experiment pairs from the previous lesson. Ask one member from each pair to collect their bottle of soaked ocean litter from the investigation in Lesson 3: Ocean litter. If required, play the Pupil video: Investigating ocean litter from 0:50 to share the results.

Select the observe, test and measure tile from the enquiry cycle in the Presentation: Investigating ocean litter and click forward to the results table.

Allow the pairs to discuss how the litter has changed in appearance, using the keywords in the presentation if required. Hand out a copy of Activity: Investigating ocean litter (one each) and allow time for the children to circulate the class and record how each litter type has changed over a week, soaked in ocean water.

Choose one bottle for each type of litter that has been soaking. Ask for a volunteer to hold each bottle at the front of the class. Invite the class to carefully observe the changes to the materials inside the bottles. Ask the class to help rearrange the volunteers from ‘most changed’ to ‘least changed’, based on what they can see.

Return to the enquiry cycle and select the conclusion tile to display slide 3. Take feedback on the questions and click to reveal answers to demonstrate how the children can summarise their conclusions from the experiment. Allow time for the children to discuss what they would include in a conclusion about their own results.
