Pupils Recognise that light from the sun can be dangerous and that there are ways to protect their eyes. In a separate 50 ml beaker, measure out 4.1 g of the base cream. Add 0.9 g of zinc oxide/paraffin paste and mix them with a glass rod until combined. This creates a sunscreen that is 10% zinc oxide, which equates to an SPF of approximately 10. Students can use this tool to develop and use a model to describe how waves are reflected, absorbed, or transmitted through various materials. The core concept of our bead design is to use modular sequence assembly in the synthesis process. Unlike existing approaches which synthesize and target beads in one workflow, thereby yielding beads limited to one sequencing task, we design beads in which the barcode sequence is assembled in a first step, and appropriate primers as targeting moieties are added in a second step, such as poly-T for scRNAseq or multiplexed panels for scDNAseq.

Zhang, F. et al. Haplotype phasing of whole human genomes using bead-based barcode partitioning in a single tube. Nat. Biotechnol. 35, 852–857 (2017). Barcode bead fabrication starts with microfluidic emulsification of a gel precursor solution serving as the bead scaffold 16, 17. Once polymerized, we recover the beads and the covalently linked primers serve as anchors for barcode synthesis.Take the experiment bag outside, in an area of direct sunlight. Record the color of the beads after 10 seconds of exposure to outside sunlight.

Lapis Lazuli Round Size 6mm Handmade - Natural Gemstone Crystal Bracelets - 6.5"-7" Elastic Crystal Bracelet Place on a tray: control and experiment bags from Part A and one of each of the materials from the front bench (clear plastic, opaque plastic, sunglasses, glass plate, foil and cloth). Take the tray outside to an area of direct sunlight.Presenters Frankie and Louise are enjoying the sunshine and put some sun cream on to protect their skin from the sun’s harmful UV rays. Students can explore the idea that different frequencies of light have different energies, and the damage to living tissue from electromagnetic radiation depends on the energy of the radiation. UV beads are beads that change colour when exposed to UV light. Dangerous ultraviolet (UV) light can be revealed using these beads. UV Beads contain pigments that turn different colours when exposed to UV light. The beads are white in ordinary, visible light but in UV light, you’ll see different colours depending on the pigment added to each bead. The beads will change from white to a colour about 50,000 times before the pigment will no longer respond to UV light.
