This term the students in LA 20 are learning about the physics of light. We’ve begun to engage in the topic by discussing what we already know about light and generating questions about what we would like to find out over the term. We’ve been nearly completely paperless too, as we’re using an ebook with interactive activities and worksheets! Yesterday we investigated “peek boxes” so that we can draw ray diagrams to describe how light travels.
In LA16 we’ve been investigating what happens when different liquids and materials are mixed together. We had lots of fun making our own glittery lava lamps. We made the base to our lava lamps using a plastic bottle, black card and lots of glitter and sequins. Then came the exciting part! First, we used a funnel to fill our plastic bottles one third full of water. We then poured in cooking oil, filling our bottles nearly to the top. After that, we added 5 drops of our favourite food colouring. Next came the magical part! We dropped an Alka Seltzer tablet into our bottles and watched the magic happen! There were lots of beautiful bubbles which rose to the surface then dropped again. It was just like a real lava lamp J
After making our lava lamps in class we were very keen to do the same thing at home, to show our brothers and sisters. So, to help us to make our own home made lava lamps, we wrote a set of instructions explaining what to do.
The Five Senses in Pre-Primary
During this term LA4 has been learning about the five senses to observe the world around us. The Five Senses are Sight, Taste, Touch, Smell and Sound. We have been using our senses to explore the properties of different materials.
To accompany our literature unit on Goldilocks and the Three Bears earlier this term we used our sense of smell and taste to try porridge with sugar, with salt and with no flavours added and we graphed our favourites.
Another one of our experiments included an investigation to see what recyclable materials are suitable for floating. We had a range of materials such as plastic bottles, foam trays, fabric, paper, paperclips, pencils, blocks, lids and yogurt pots. Our year 6 helpers Sienna and Maddy assisted us to conduct a test in the water trolley and water trough in our class. We used our senses of sight and touch to describe the properties. We had to use describing words, called adjectives, to describe what properties made each item float or sink. Aidan B said “The foam tray is large and flat which helps it to float.” Jayden said the metal paperclip was small and hard so it will sink.”
Asja said “The plastic bottle will be waterproof if the lid is closed. The water can’t get through plastic”
We then had to design and make a boat for Technology and Enterprise using the knowledge we had acquired during our floating and sinking investigation. We were amazed at the students’ ability to construct a labelled plan, and flexibly use the recycled resources available to build their boats using care and cooperation, even solving problems if the piece they planned to use was no longer available.
Balin included a yogurt pot tied to the side of his boat. “I made an air bubble on the side of my boat that will help it float.”
Zander used a meat tray “because it is light and will make a good bottom for a boat.”
Taj M attached a wooden spoon under his meat tray to make the boat stable. When asked about this he said “I’ve seen lots of boats with propellers or the bit under the middle.”
Muds and Suds
This term we have been studying the Science of cleanliness. We began by reading Mrs Wishy Washy and then we role played how Mrs Wishy Washy cleaned the animals. We then had a real dog, ‘Titch’ come to our class and we all had a turn at washing and drying him. We found out that it is important to keep our pets clean for both their own health and the health of the people they live with too.
Titch was really well behaved while we washed, cleaned and dried him!
Sundial Experiment 16-8-13 (Soraya)
On Friday we made some sundials. We used paper plates and old pencils. First we drew a hole in the centre of the plate. Then stuck the pencil through the holes very carefully. Then we went over to the Kindy area and placed them into the dirt. We went each hour to mark the shadow. Mine went up, down, up and up, which was a bit strange. Once we went back inside and Mrs. V. gave us some string and we measured them.
Sundial Experiment 16-8-13 (Sara)
On Friday LA17 made sundials. First we put a pencil into a paper plate. Then we walked outside of the Kindy and through the gate. Then we stuck the sundials in the ground to make a shadow. We marked where the shadow was and went back to our classroom. We repeated this at 12pm, 1pm and 2pm. At about 2pm we pulled the sundials out of the ground and we went back to the classroom. We wrote the times on the marks we did. My sundial didn’t go very well because mine broke.
Sundial Experiment 16-8-13 (Brandon)
On Friday last week, LA17 made sundials. First we found the centre of the paper plate and stuck a pencil in the centre. Then we put the paper plate outside on the ground next to the Kindy area. We marked where the shadow pointed to. We checked every hour from 11am to 2pm. Mine turned out to be in order of smallest to largest. Once we had finished we did a graph of our shadows. We also answered some questions about the sundials.
To celebrate National Science Week this year, Harmony ran our second annual Science Challenge as a Land Yacht Race. This year there were two categories, years 1-3 and years 4-6. There were close to 80 entries in the race this year with some truly amazing and innovative designs. Students followed a design brief which stated that they must only use recycled materials and that their yacht could be no larger than 1 square metre. Congratulations to all students and families who participated. The final results were:
1st Place – Charlee (LA 8) 10.61 metres
2nd Place – Tioni (LA 17) 9.1 metres
3rd Place – Noah (LA 16) 8.95 metres
1st Place – Ella (LA 27) and Kate (LA 26) 11.34 metres
2nd Place – Oliver (LA 21) 8.36 metres
3rd Place – Sinead (LA 26) 7.6m metres
The Inter-School Challenge
Charlee, Tioni, Oliver, Ella and Kate all represented Harmony at the first ever Inter-School Science Challenge for the Cockburn Central Education
Network on Tuesday the 20th of August at Atwell Primary School. In the years 1-3 category Charlee placed 5th and Tioni placed 7th. In the years 4-6category Oliver placed 4th and congratulations to Kate and Ella who won first place!
We’re looking forward to National Science Week next year for our next Harmony and Cockburn Interschool challenges!
