Having fun in science

It has been a fun couple of months teaching Science. The students love to conduct experiments and love being able to see and touch things first hand. It’s a privilege being able to take the students outside in MEP. It’s great allowing them the freedom to walk amongst the gardens whilst looking at and documenting the things they can see. Being able to see, touch and feel real living things really helps to highlight the similarities and differences between various topics. Here are some other fun things we’ve done this month.

Science Experiments:

For each experiment we made a prediction, discussed the methods, and drew up conclusions. Discussing a prediction has really helped the students develop abstract ideas in relation to considering all the possible outcomes.

1) How does a plant grow?

We planted 4 different types of seeds and made sure each plant got sufficient water, air and sunlight each day. Some seeds began to show results after 3 days, sprouting into baby plants called seedlings. The tiny green shoots grew up towards the light and white stringy roots grew down.

  • Sunflower seeds.
  • Papaya seeds.
  • Basil seeds.
  • Zinia seeds.

2) How does water move through a plant?

We took some cabbage leaves and flowers and placed them into various pots of green and red food colouring. After a couple of days the flowers and cabbage leaves changed colour and at the end of each stem were coloured dots. These dots are narrow tubes inside the stem that draw up the dyed water into the petals showing the direction of water flow.

3) What do the parts of the plant do?

A carrot is seen to be the root of a carrot plant.What do roots do?

First we propped the bottom half of a carrot in water and second, placed the cut top of another on a saucer of water covering the top with a glass. The carrot propped in water began to grow extra thin white roots to help it soak up the water. The carrot top we placed on the saucer of water, like a root, soaked up the water, helping the stalk to grow.

We also had lots of fun in science this month making crafts based on the new things we had learnt. Here are just some of the things that worked well including a list of materials used.

  • Life cycle of a plant- Paper plates, circular sectioned template, split pins, scissors.
  • Seed packets- Rice, seed packaging template, scissors, glue.
  • Two dimensions flowers- straws, string, cake cases, leaves, rice, scissors, glue, paper.
  • Leaf rubbing- Leaves, crayons, paper.
