A differentiated test which assesses studenta around level 1 to 4 (old NC levels)
You can of course alter in any way you wish. The assesment requires students to use a hand lens to draw what they see.
The scores are 0, 1 or 2 (you change or delete as you wish) the idea being 0=no understanding, 1=some understanding, 2=understands fully...this helps you gauge the level of understanding for this topic
This is a tried, tested and improved assesment that has worked well with many students.
The assesment is based on the old NC levels 1 to 5 (subdivided into a,b & c)but you can convert into any level description you need, frankly a staged 1 to 5 indicator is as useful as ever whatever you may wish to call it.
I have devised a sytem which gives you a measure of success: each question can score 0, 1 or 2, if a student scores a 2 then you can say they understand the concept fully, score of 1 they understand partially, 0 means they may have experienced the concept but do not understand it much if at all.
The support sheet can be used as a teaching scheme for staff. Split into 3 columns the first column states what concept is being testsd, 2nd column tells you what is required for a score og 1, 3rd column what is required for a score of 2.
I have used this sytem to calculate a score for students...if they achieve 75% or more then I believe you can say they have achieved that level.
A simple quiz with well thought out and tested questions intended to stimulate thought and discussion about materials and their properties.
There is no mark scheme as I have found that students come up with unexpected but valid answers which can engage the class and foster interest
Simple worksheet that allows students to invstigate materials and their uses around school (at home for HW).
Students can look at specific objects(chair) and write down what it seems to be from.
Students are also encouraged to look for the material and say what it is used for...so that materials and properties are approached from both ways.
Then the more tricky task of putting materials into groups, students can classify them in their own way..get ready for some unusual classification techniques.
As an extension students can continue with materials/objects of their own choice..this usually introduces the student's own interests into scientific method.
Students are given some dirty salt (salt +sand/soil..whatever you wish) I have even simulated urine(orange juice) to reinforce the plight of poor hygeine in some countries.
The sheet takes students through the 3 steps of purifying the salt.
The final step of evaporating the water using evaporating basins can be tricky if the heat is left on too long.....if no bunsens/heat is available you can just leave the solutions to "dry out" naturally..you can get nice crystals forming over a couple of days.
Why not take the students out for fish and chips later on (keeping a sample of your salt to sprinkle on your chips)
Lovely activity, not for the faint hearted.
Give students a selection of materials which they examine and describe simply.
They then (with the required H&S) heat the material/object using a bunsen(roaring or yellow...you decide), tongs, observe and describe the material afterwards.
I have done this expt using tea light candles in a classroom, with bench mats and an extra pair of eyes it worked beautifully.
This promotes many aspects of chemical changes, durability, suitability etc etc of materials for specific tasks
Students use hand lenses, magnifiers, whatever you have available....this can lead to a "not fair" discussion as some students only have low magnification.
The worksheet contains pictures of very small living things with varrying amounts of legs, antenae, wings, spots, colours...students must use the magnifier to draw as carefully as they can the pictures.
The students can then mark their own efforts after you tell them what detail you expected and they should have spotted..be prepared for lots of moaning and a bit of banter.
A simple activity which could last a few lessons..depending on what you/the students find.
Possible extra apparatus you could use: mirrors, cotton wool buds to help counting (don't use cocktail sticks unless you have a few hors spare to fill in the incident forms).
The clear picture on the worksheet shows students which teeth are which and all they have to do is count their own and record the numbers. They can try on their own in pairs, use their tongue to keep track or cotton wool buds to "tap" the teeth as they count.
A mirror is very useful.
The activity usyually lends itself to much discussion regarding missing teeth, extra teeth, decay, bad breath, bacteria, diet etc.
I like it because you can just watch the students find out about "themselves" remind them it is not a competition, unless you want it to be.
I love these activities...you must be prepared for all sorts of ideas from the students...but more importantly allow them to try it out..PLEASE DO NOT tell them "this won't work because" and then give them all the answers that are required by law and the curriculum....let them excercise their own problem solving skills and love you for letting them try it out..in a controlled way of course.
Basically they need to find out/ try out/ explore what conditions seeds need to germinate successfully
I have had students burn some seeds with a bunsen as they had seen plants growing after a forest fire..indeed you can discuss thet some seeds need extreme heat before they germinate.
Other ideas students have had:
put in freezer overnight, soak in water, hit with rock, put in acid, keep in dark, keep in light, and so it goes on
Worksheet that enables students to draw what they see under the microscope, suggested samples are on the sheet but of course you can add your own or even leave some blank for students to suggest.
I have had students hunting for insects, leaves are popular, worms, ants are tricky but petri dishes are helpful, dust, finger nail dirt, etc etc
Students love to enter the world of the microscopic..be prepared to allow a couple or 3 lessons to let their imagination soar.
Very simple worksheet designed to make students realize that scientific names of parts of plants...roots, stem, flower, fruit have common names that they already know...carrot, leek, fruit
I have provided a shopping bag of fruit & veg to display and just let the students explore and realize, of course a set of photos works just as well but you can't eat them afterwards
A simple A4 template that allows students to make a small but useable periscope, you will need the mirror card to glue onto the periscope.
Challenges to make them longer...ie make an extension tube...does not need to be square! could be tin foil tube etc...periscope is cut in half and the ends slipped over the extension tube.
I have had students make a "sea" out of tables, they crawl around underneath and pop up a periscope in gaps between tables to look around.
A beautiful demo with students timing with stopwatches.
I typically do this around bonfire night, but if you buy some rockets (the banging type) you can do this anytime.
You really need a school playing field with no sports or the like going on.
Wedge the wooden stick of the rocket (any size will do) into the ground in one corner of the field, get students with stopwatches as far away from the rocket as poss (yes for safety..but more importantly the further the better results you get)
YOU light the rocket and let students 200/300m away know that by usual jumpimg up and down or arm waving...students prepare to start stopwatches as soon as they see the FLASH (on the ground because the rocket is wedged into the ground)...the sound of course eerily does not get heard until a second or so later.
Do this as many times as you have rockets, all results can be pooled and averaged later on.
There is scope for this demo to be done a mile or 2 apart..using mobile phones and taking students to a nearby park..the rocket is released and explodes high up above school field...students do the timing thing from as far away as is practicable...Google maps will give you an accurate distance to calculate speed of sound should you wish
We have had so much fun with this!
careful...some students (especially SEN) can get annoyed & "throw their toys out of the pram"...but I often "over" challenge my students so that they can practice handling "upset"..very important life skill.
Working in pairs one student holds a book or card infront of the other student so that they can not see the worksheet, using a mirror they can look at a reflection of the star and try to draw a straight line on the star outline without touching either of the boundary lines...try it yourself first and get rid of all that frustration
A nice powerpoint bunch of slides..sound followed by the answer, you can edit the answers to suit yourself and names of staff for a bit of fun.
Add extra slides with your own sounds/student's or staff voices. Use your imagination...the idea is to recognize sounds...they can be anything..dropping things, flushing, rubbing, scratching, pets, etc etc etc
With limited resorces this gives students an opportunity to test out "sound proofing"
You just need a table, paper clip, ruler and a selection of materials that may be useful in blocking out the noise from a noisy neighbour
Give the students as much guidance as you like or alternatively, as I prefer, just give them the limited resorces and tell them to devise a "fair" test.
Potential for discussion, competition and looking silly walking around with ear protectors made out of the winning material
This is one of my most succesful Investigations/puzzles/problem solving tasks I produced and used over many years
The main aim is to protect a raw egg. Specif materials are given to "teams" they can use them abuse them, cut, rip, chew or even ignore them, but for FAIRNESS every team has the SAME materials.
This encourages Independent work, team work, prblem solving. It works well with motion studies: air bags, crumple zones etc.
The egg with it's protection is placed (by the students) onto the platform...The tricky news..you need to build a simple platform out of 2 bits of wood and 3 dowel rods..pretty easy really, mine has lasted 20 years but shows it.
The creation is placed on the base, you gently lower the top wooden board on top (sandwich like) and begin to drop a mass (I used a 2kg mass) from higher & higher..until the egg is "SQuashed" you must be able to see/feel the egg after each drop.
Over the years I have had spectacular successes & failures...lots of news paper on floor is useful.
Best ever result a 2kg drop from over 2.5m and the egg survived!..the crumple zone produced was superb.
Ideas the students had..air bag (balloon above egg/ below egg, egg INSIDE balloon and pumped up...great fun!
tubes made from paper/card, padding from ,aterials, hammocks using string etc etc
I spent the first lesson or 2 letting the students just make anything..next lesson...TESTED one by one infront of the class..then if you wish discuss the "Winner" & why?...then repeat expt if you wish for the next couple of lessons.
Before hand I usually did the "squash the egg with yiour hand" (in a clear plastic bag) yes I know you know they are strong but have you actually got the students to do it? got other staff..big bloke staff..crying because they can't...NO rings or fingernails just grip...then after they have tried and failed just drop iton the table to prove it is an egg!
