Science Activities!

Make a Solar Oven

Equipment: foil, cardboard box, 2 sticks, scissors, paper plate, black paper/card, marshmallows and/or chocolate buttons, clingfilm.

How to: cut the lid of the box so that it opens on a hinge like a pizza box; cover the inside of this lid with foil; place the black paper/card on the base of the box; place food on a paper plate and place inside the box; cover the opening above the food with clingfilm to keep the food clean; prop open the lid with the sticks and position the box so that the foil reflects light onto the food.  

What is happening? The black paper/card absorbs the heat and the foil reflects the heat from the sun onto the food, making it melt.

Taking it further: children could explore what happens they use black card/paper as their plate. At what speed do different types of food melt?

Minibeast Modelling

Equipment: foil.

How to: Challenge the children to use a piece of foil to create an insect and a spider. Ask them to explain what is different about them and what is the same: body parts, habitats, what they eat, how they move etc.

Taking it further: if class-based, children could classify, sort and compare their different minibeasts.

Science experiment! πŸ¦‹

Chromatography Butterflies

Equipment: filter paper/a circle of craft paper, felt tips, glass of water, pipe cleaners.

How to: using a felt tip, draw a single-line circle around the middle of the filter paper; only use one colour; fold the circle into a cone shape; place the cone in the glass so that it is just touching the water; what happens as the paper absorbs the water?  After a couple of hours, lie the paper out to dry, then use a pipe cleaner to scrunch the middle together and create a butterfly shape.

What is happening? Chromatography is a technique for separating mixtures. Here, the ink of the felt-tip (the sample) is put on the paper (the stationary phase) and the water then moves up the paper (the mobile phase). The different pigments of the ink have different properties (more/less soluble etc) which means they travel at different speeds and separate.

Taking it further: children could explore different felt tip colours, different sizes of circles or different sizes and types of paper. They could also use rulers to measure the distance travelled by the different colours.

Home Learning 🌈🏠

Check out all the amazing work a pupil has sent me this week. He has completed his Google Classroom tasks as well as completing some work about Captain Tom Moore and a rainbow for the NHS workers.

Keep it up! Remember you can all email me any pictures you wish to share.
